By following the advice and examples provided here, you’ll be able to produce a top-notch comparison essay that showcases your analytical skills and critical thinking abilities.

Understanding the Basics

Before diving into writing a comparison essay, it’s essential to understand the basics of comparison writing. A comparison essay, also known as a comparative essay, requires you to analyze two or more subjects by highlighting their similarities and differences. This type of essay aims to show how these subjects are similar or different in various aspects.

When writing a comparison essay, you should have a clear thesis statement that identifies the subjects you are comparing and the main points of comparison. It’s essential to structure your essay effectively by organizing your ideas logically. You can use different methods of organization, such as the block method or point-by-point method, to present your comparisons.

Additionally, make sure to include evidence and examples to support your comparisons. Use specific details and examples to strengthen your arguments and clarify the similarities and differences between the subjects. Lastly, remember to provide a strong conclusion that summarizes your main points and reinforces the significance of your comparison.

Choosing a Topic for Comparison Essay

When selecting a topic for your comparison essay, it’s essential to choose two subjects that have some similarities and differences to explore. You can compare two books, two movies, two historical figures, two theories, or any other pair of related subjects.

Consider selecting topics that interest you or that you are familiar with to make the writing process more engaging and manageable. Additionally, ensure that the subjects you choose are suitable for comparison and have enough material for analysis.

It’s also helpful to brainstorm ideas and create a list of potential topics before making a final decision. Once you have a few options in mind, evaluate them based on the relevance of the comparison, the availability of credible sources, and your own interest in the subjects.

Remember that a well-chosen topic is one of the keys to writing a successful comparison essay, so take your time to select subjects that will allow you to explore meaningful connections and differences in a compelling way.

Finding the Right Pairing

When writing a comparison essay, it’s crucial to find the right pairing of subjects to compare. Choose subjects that have enough similarities and differences to make a meaningful comparison. Consider the audience and purpose of your essay to determine what pairing will be most effective.

Look for subjects that you are passionate about or have a deep understanding of. This will make the writing process easier and more engaging. Additionally, consider choosing subjects that are relevant and timely, as this will make your essay more interesting to readers.

Don’t be afraid to think outside the box when finding the right pairing. Sometimes unexpected combinations can lead to the most compelling comparisons. Conduct thorough research on both subjects to ensure you have enough material to work with and present a balanced comparison.

Structuring Your Comparison Essay

When writing a comparison essay, it is essential to organize your ideas in a clear and logical manner. One effective way to structure your essay is to use a point-by-point comparison or a block comparison format.

Point-by-Point Comparison	Block Comparison
In this format, you will discuss one point of comparison between the two subjects before moving on to the next point.	In this format, you will discuss all the points related to one subject before moving on to the next subject.
Allows for a more detailed analysis of each point of comparison.	Provides a clear and structured comparison of the two subjects.
Can be helpful when the subjects have multiple similarities and differences to explore.	May be easier to follow for readers who prefer a side-by-side comparison of the subjects.

Whichever format you choose, make sure to introduce your subjects, present your points of comparison, provide evidence or examples to support your comparisons, and conclude by summarizing the main points and highlighting the significance of your comparison.

Creating a Clear Outline

Before you start writing your comparison essay, it’s essential to create a clear outline. An outline serves as a roadmap that helps you stay organized and focused throughout the writing process. Here are some steps to create an effective outline:

1. Identify the subjects of comparison: Start by determining the two subjects you will be comparing in your essay. Make sure they have enough similarities and differences to make a meaningful comparison.

2. Brainstorm key points: Once you have chosen the subjects, brainstorm the key points you want to compare and contrast. These could include characteristics, features, themes, or arguments related to each subject.

3. Organize your points: Arrange your key points in a logical order. You can choose to compare similar points side by side or alternate between the two subjects to highlight differences.

4. Develop a thesis statement: Based on your key points, develop a clear thesis statement that states the main purpose of your comparison essay. This statement should guide the rest of your writing and provide a clear direction for your argument.

5. Create a structure: Divide your essay into introduction, body paragraphs, and conclusion. Each section should serve a specific purpose and contribute to the overall coherence of your essay.

By creating a clear outline, you can ensure that your comparison essay flows smoothly and effectively communicates your ideas to the reader.

Engaging the Reader

When writing a comparison essay, it is crucial to engage the reader right from the beginning. You want to hook their attention and make them want to keep reading. Here are some tips to engage your reader:

Start with a strong opening statement or question that entices the reader to continue reading.
Use vivid language and descriptive imagery to paint a clear picture in the reader’s mind.
Provide interesting facts or statistics that pique the reader’s curiosity.
Create a compelling thesis statement that outlines the purpose of your comparison essay.

By engaging the reader from the start, you set the stage for a successful and impactful comparison essay that keeps the reader engaged until the very end.

Point-by-Point vs Block Method

When writing a comparison essay, you have two main options for structuring your content: the point-by-point method and the block method. Each method has its own advantages and may be more suitable depending on the type of comparison you are making.

Point-by-Point Method: This method involves discussing one point of comparison at a time between the two subjects. You will go back and forth between the subjects, highlighting similarities and differences for each point. This method allows for a more detailed and nuanced analysis of the subjects.
Block Method: In contrast, the block method involves discussing all the points related to one subject first, followed by all the points related to the second subject. This method provides a more straightforward and organized comparison but may not delve as deeply into the individual points of comparison.

Ultimately, the choice between the point-by-point and block methods depends on the complexity of your comparison and the level of detail you want to explore. Experiment with both methods to see which one best suits your writing style and the specific requirements of your comparison essay.

Selecting the Best Approach

When it comes to writing a comparison essay, selecting the best approach is crucial to ensure a successful and effective comparison. There are several approaches you can take when comparing two subjects, including the block method and the point-by-point method.

The block method: This approach involves discussing all the similarities and differences of one subject first, followed by a thorough discussion of the second subject. This method is useful when the two subjects being compared are quite different or when the reader may not be familiar with one of the subjects.

The point-by-point method: This approach involves alternating between discussing the similarities and differences of the two subjects in each paragraph. This method allows for a more in-depth comparison of specific points and is often preferred when the two subjects have many similarities and differences.

Before selecting an approach, consider the nature of the subjects being compared and the purpose of your comparison essay. Choose the approach that will best serve your purpose and allow for a clear, organized, and engaging comparison.

Comparing and Contrasting

What this handout is about.

This handout will help you first to determine whether a particular assignment is asking for comparison/contrast and then to generate a list of similarities and differences, decide which similarities and differences to focus on, and organize your paper so that it will be clear and effective. It will also explain how you can (and why you should) develop a thesis that goes beyond “Thing A and Thing B are similar in many ways but different in others.”

Introduction

In your career as a student, you’ll encounter many different kinds of writing assignments, each with its own requirements. One of the most common is the comparison/contrast essay, in which you focus on the ways in which certain things or ideas—usually two of them—are similar to (this is the comparison) and/or different from (this is the contrast) one another. By assigning such essays, your instructors are encouraging you to make connections between texts or ideas, engage in critical thinking, and go beyond mere description or summary to generate interesting analysis: when you reflect on similarities and differences, you gain a deeper understanding of the items you are comparing, their relationship to each other, and what is most important about them.

Recognizing comparison/contrast in assignments

Some assignments use words—like compare, contrast, similarities, and differences—that make it easy for you to see that they are asking you to compare and/or contrast. Here are a few hypothetical examples:

Compare and contrast Frye’s and Bartky’s accounts of oppression.
Compare WWI to WWII, identifying similarities in the causes, development, and outcomes of the wars.
Contrast Wordsworth and Coleridge; what are the major differences in their poetry?

Notice that some topics ask only for comparison, others only for contrast, and others for both.

But it’s not always so easy to tell whether an assignment is asking you to include comparison/contrast. And in some cases, comparison/contrast is only part of the essay—you begin by comparing and/or contrasting two or more things and then use what you’ve learned to construct an argument or evaluation. Consider these examples, noticing the language that is used to ask for the comparison/contrast and whether the comparison/contrast is only one part of a larger assignment:

Choose a particular idea or theme, such as romantic love, death, or nature, and consider how it is treated in two Romantic poems.
How do the different authors we have studied so far define and describe oppression?
Compare Frye’s and Bartky’s accounts of oppression. What does each imply about women’s collusion in their own oppression? Which is more accurate?
In the texts we’ve studied, soldiers who served in different wars offer differing accounts of their experiences and feelings both during and after the fighting. What commonalities are there in these accounts? What factors do you think are responsible for their differences?

You may want to check out our handout on understanding assignments for additional tips.

Using comparison/contrast for all kinds of writing projects

Sometimes you may want to use comparison/contrast techniques in your own pre-writing work to get ideas that you can later use for an argument, even if comparison/contrast isn’t an official requirement for the paper you’re writing. For example, if you wanted to argue that Frye’s account of oppression is better than both de Beauvoir’s and Bartky’s, comparing and contrasting the main arguments of those three authors might help you construct your evaluation—even though the topic may not have asked for comparison/contrast and the lists of similarities and differences you generate may not appear anywhere in the final draft of your paper.

Discovering similarities and differences

Making a Venn diagram or a chart can help you quickly and efficiently compare and contrast two or more things or ideas. To make a Venn diagram, simply draw some overlapping circles, one circle for each item you’re considering. In the central area where they overlap, list the traits the two items have in common. Assign each one of the areas that doesn’t overlap; in those areas, you can list the traits that make the things different. Here’s a very simple example, using two pizza places:

Venn diagram indicating that both Pepper's and Amante serve pizza with unusual ingredients at moderate prices, despite differences in location, wait times, and delivery options

To make a chart, figure out what criteria you want to focus on in comparing the items. Along the left side of the page, list each of the criteria. Across the top, list the names of the items. You should then have a box per item for each criterion; you can fill the boxes in and then survey what you’ve discovered.

Here’s an example, this time using three pizza places:

	Pepper’s	Amante	Papa John’s
Location
Price
Delivery
Ingredients
Service
Seating/eating in
Coupons

As you generate points of comparison, consider the purpose and content of the assignment and the focus of the class. What do you think the professor wants you to learn by doing this comparison/contrast? How does it fit with what you have been studying so far and with the other assignments in the course? Are there any clues about what to focus on in the assignment itself?

Here are some general questions about different types of things you might have to compare. These are by no means complete or definitive lists; they’re just here to give you some ideas—you can generate your own questions for these and other types of comparison. You may want to begin by using the questions reporters traditionally ask: Who? What? Where? When? Why? How? If you’re talking about objects, you might also consider general properties like size, shape, color, sound, weight, taste, texture, smell, number, duration, and location.

Two historical periods or events

When did they occur—do you know the date(s) and duration? What happened or changed during each? Why are they significant?
What kinds of work did people do? What kinds of relationships did they have? What did they value?
What kinds of governments were there? Who were important people involved?
What caused events in these periods, and what consequences did they have later on?

Two ideas or theories

What are they about?
Did they originate at some particular time?
Who created them? Who uses or defends them?
What is the central focus, claim, or goal of each? What conclusions do they offer?
How are they applied to situations/people/things/etc.?
Which seems more plausible to you, and why? How broad is their scope?
What kind of evidence is usually offered for them?

Two pieces of writing or art

What are their titles? What do they describe or depict?
What is their tone or mood? What is their form?
Who created them? When were they created? Why do you think they were created as they were? What themes do they address?
Do you think one is of higher quality or greater merit than the other(s)—and if so, why?
For writing: what plot, characterization, setting, theme, tone, and type of narration are used?
Where are they from? How old are they? What is the gender, race, class, etc. of each?
What, if anything, are they known for? Do they have any relationship to each other?
What are they like? What did/do they do? What do they believe? Why are they interesting?
What stands out most about each of them?

Deciding what to focus on

By now you have probably generated a huge list of similarities and differences—congratulations! Next you must decide which of them are interesting, important, and relevant enough to be included in your paper. Ask yourself these questions:

What’s relevant to the assignment?
What’s relevant to the course?
What’s interesting and informative?
What matters to the argument you are going to make?
What’s basic or central (and needs to be mentioned even if obvious)?
Overall, what’s more important—the similarities or the differences?

Suppose that you are writing a paper comparing two novels. For most literature classes, the fact that they both use Caslon type (a kind of typeface, like the fonts you may use in your writing) is not going to be relevant, nor is the fact that one of them has a few illustrations and the other has none; literature classes are more likely to focus on subjects like characterization, plot, setting, the writer’s style and intentions, language, central themes, and so forth. However, if you were writing a paper for a class on typesetting or on how illustrations are used to enhance novels, the typeface and presence or absence of illustrations might be absolutely critical to include in your final paper.

Sometimes a particular point of comparison or contrast might be relevant but not terribly revealing or interesting. For example, if you are writing a paper about Wordsworth’s “Tintern Abbey” and Coleridge’s “Frost at Midnight,” pointing out that they both have nature as a central theme is relevant (comparisons of poetry often talk about themes) but not terribly interesting; your class has probably already had many discussions about the Romantic poets’ fondness for nature. Talking about the different ways nature is depicted or the different aspects of nature that are emphasized might be more interesting and show a more sophisticated understanding of the poems.

Your thesis

The thesis of your comparison/contrast paper is very important: it can help you create a focused argument and give your reader a road map so they don’t get lost in the sea of points you are about to make. As in any paper, you will want to replace vague reports of your general topic (for example, “This paper will compare and contrast two pizza places,” or “Pepper’s and Amante are similar in some ways and different in others,” or “Pepper’s and Amante are similar in many ways, but they have one major difference”) with something more detailed and specific. For example, you might say, “Pepper’s and Amante have similar prices and ingredients, but their atmospheres and willingness to deliver set them apart.”

Be careful, though—although this thesis is fairly specific and does propose a simple argument (that atmosphere and delivery make the two pizza places different), your instructor will often be looking for a bit more analysis. In this case, the obvious question is “So what? Why should anyone care that Pepper’s and Amante are different in this way?” One might also wonder why the writer chose those two particular pizza places to compare—why not Papa John’s, Dominos, or Pizza Hut? Again, thinking about the context the class provides may help you answer such questions and make a stronger argument. Here’s a revision of the thesis mentioned earlier:

Pepper’s and Amante both offer a greater variety of ingredients than other Chapel Hill/Carrboro pizza places (and than any of the national chains), but the funky, lively atmosphere at Pepper’s makes it a better place to give visiting friends and family a taste of local culture.

You may find our handout on constructing thesis statements useful at this stage.

Organizing your paper

There are many different ways to organize a comparison/contrast essay. Here are two:

Subject-by-subject

Begin by saying everything you have to say about the first subject you are discussing, then move on and make all the points you want to make about the second subject (and after that, the third, and so on, if you’re comparing/contrasting more than two things). If the paper is short, you might be able to fit all of your points about each item into a single paragraph, but it’s more likely that you’d have several paragraphs per item. Using our pizza place comparison/contrast as an example, after the introduction, you might have a paragraph about the ingredients available at Pepper’s, a paragraph about its location, and a paragraph about its ambience. Then you’d have three similar paragraphs about Amante, followed by your conclusion.

The danger of this subject-by-subject organization is that your paper will simply be a list of points: a certain number of points (in my example, three) about one subject, then a certain number of points about another. This is usually not what college instructors are looking for in a paper—generally they want you to compare or contrast two or more things very directly, rather than just listing the traits the things have and leaving it up to the reader to reflect on how those traits are similar or different and why those similarities or differences matter. Thus, if you use the subject-by-subject form, you will probably want to have a very strong, analytical thesis and at least one body paragraph that ties all of your different points together.

A subject-by-subject structure can be a logical choice if you are writing what is sometimes called a “lens” comparison, in which you use one subject or item (which isn’t really your main topic) to better understand another item (which is). For example, you might be asked to compare a poem you’ve already covered thoroughly in class with one you are reading on your own. It might make sense to give a brief summary of your main ideas about the first poem (this would be your first subject, the “lens”), and then spend most of your paper discussing how those points are similar to or different from your ideas about the second.

Point-by-point

Rather than addressing things one subject at a time, you may wish to talk about one point of comparison at a time. There are two main ways this might play out, depending on how much you have to say about each of the things you are comparing. If you have just a little, you might, in a single paragraph, discuss how a certain point of comparison/contrast relates to all the items you are discussing. For example, I might describe, in one paragraph, what the prices are like at both Pepper’s and Amante; in the next paragraph, I might compare the ingredients available; in a third, I might contrast the atmospheres of the two restaurants.

If I had a bit more to say about the items I was comparing/contrasting, I might devote a whole paragraph to how each point relates to each item. For example, I might have a whole paragraph about the clientele at Pepper’s, followed by a whole paragraph about the clientele at Amante; then I would move on and do two more paragraphs discussing my next point of comparison/contrast—like the ingredients available at each restaurant.

There are no hard and fast rules about organizing a comparison/contrast paper, of course. Just be sure that your reader can easily tell what’s going on! Be aware, too, of the placement of your different points. If you are writing a comparison/contrast in service of an argument, keep in mind that the last point you make is the one you are leaving your reader with. For example, if I am trying to argue that Amante is better than Pepper’s, I should end with a contrast that leaves Amante sounding good, rather than with a point of comparison that I have to admit makes Pepper’s look better. If you’ve decided that the differences between the items you’re comparing/contrasting are most important, you’ll want to end with the differences—and vice versa, if the similarities seem most important to you.

Our handout on organization can help you write good topic sentences and transitions and make sure that you have a good overall structure in place for your paper.

Cue words and other tips

To help your reader keep track of where you are in the comparison/contrast, you’ll want to be sure that your transitions and topic sentences are especially strong. Your thesis should already have given the reader an idea of the points you’ll be making and the organization you’ll be using, but you can help them out with some extra cues. The following words may be helpful to you in signaling your intentions:

like, similar to, also, unlike, similarly, in the same way, likewise, again, compared to, in contrast, in like manner, contrasted with, on the contrary, however, although, yet, even though, still, but, nevertheless, conversely, at the same time, regardless, despite, while, on the one hand … on the other hand.

For example, you might have a topic sentence like one of these:

Compared to Pepper’s, Amante is quiet.
Like Amante, Pepper’s offers fresh garlic as a topping.
Despite their different locations (downtown Chapel Hill and downtown Carrboro), Pepper’s and Amante are both fairly easy to get to.

10.7 Comparison and Contrast

Learning objectives.

Determine the purpose and structure of comparison and contrast in writing.
Explain organizational methods used when comparing and contrasting.
Understand how to write a compare-and-contrast essay.

The Purpose of Comparison and Contrast in Writing

Comparison in writing discusses elements that are similar, while contrast in writing discusses elements that are different. A compare-and-contrast essay , then, analyzes two subjects by comparing them, contrasting them, or both.

The key to a good compare-and-contrast essay is to choose two or more subjects that connect in a meaningful way. The purpose of conducting the comparison or contrast is not to state the obvious but rather to illuminate subtle differences or unexpected similarities. For example, if you wanted to focus on contrasting two subjects you would not pick apples and oranges; rather, you might choose to compare and contrast two types of oranges or two types of apples to highlight subtle differences. For example, Red Delicious apples are sweet, while Granny Smiths are tart and acidic. Drawing distinctions between elements in a similar category will increase the audience’s understanding of that category, which is the purpose of the compare-and-contrast essay.

Similarly, to focus on comparison, choose two subjects that seem at first to be unrelated. For a comparison essay, you likely would not choose two apples or two oranges because they share so many of the same properties already. Rather, you might try to compare how apples and oranges are quite similar. The more divergent the two subjects initially seem, the more interesting a comparison essay will be.

Writing at Work

Comparing and contrasting is also an evaluative tool. In order to make accurate evaluations about a given topic, you must first know the critical points of similarity and difference. Comparing and contrasting is a primary tool for many workplace assessments. You have likely compared and contrasted yourself to other colleagues. Employee advancements, pay raises, hiring, and firing are typically conducted using comparison and contrast. Comparison and contrast could be used to evaluate companies, departments, or individuals.

Brainstorm an essay that leans toward contrast. Choose one of the following three categories. Pick two examples from each. Then come up with one similarity and three differences between the examples.

Romantic comedies
Internet search engines
Cell phones

Brainstorm an essay that leans toward comparison. Choose one of the following three items. Then come up with one difference and three similarities.

Department stores and discount retail stores
Fast food chains and fine dining restaurants
Dogs and cats

The Structure of a Comparison and Contrast Essay

The compare-and-contrast essay starts with a thesis that clearly states the two subjects that are to be compared, contrasted, or both and the reason for doing so. The thesis could lean more toward comparing, contrasting, or both. Remember, the point of comparing and contrasting is to provide useful knowledge to the reader. Take the following thesis as an example that leans more toward contrasting.

Thesis statement: Organic vegetables may cost more than those that are conventionally grown, but when put to the test, they are definitely worth every extra penny.

Here the thesis sets up the two subjects to be compared and contrasted (organic versus conventional vegetables), and it makes a claim about the results that might prove useful to the reader.

You may organize compare-and-contrast essays in one of the following two ways:

According to the subjects themselves, discussing one then the other
According to individual points, discussing each subject in relation to each point

See Figure 10.1 “Comparison and Contrast Diagram” , which diagrams the ways to organize our organic versus conventional vegetables thesis.

Figure 10.1 Comparison and Contrast Diagram

The organizational structure you choose depends on the nature of the topic, your purpose, and your audience.

Given that compare-and-contrast essays analyze the relationship between two subjects, it is helpful to have some phrases on hand that will cue the reader to such analysis. See Table 10.3 “Phrases of Comparison and Contrast” for examples.

Table 10.3 Phrases of Comparison and Contrast

Comparison	Contrast
one similarity	one difference
another similarity	another difference
both	conversely
like	in contrast
likewise	unlike
similarly	while
in a similar fashion	whereas

Create an outline for each of the items you chose in Note 10.72 “Exercise 1” and Note 10.73 “Exercise 2” . Use the point-by-point organizing strategy for one of them, and use the subject organizing strategy for the other.

Writing a Comparison and Contrast Essay

First choose whether you want to compare seemingly disparate subjects, contrast seemingly similar subjects, or compare and contrast subjects. Once you have decided on a topic, introduce it with an engaging opening paragraph. Your thesis should come at the end of the introduction, and it should establish the subjects you will compare, contrast, or both as well as state what can be learned from doing so.

The body of the essay can be organized in one of two ways: by subject or by individual points. The organizing strategy that you choose will depend on, as always, your audience and your purpose. You may also consider your particular approach to the subjects as well as the nature of the subjects themselves; some subjects might better lend themselves to one structure or the other. Make sure to use comparison and contrast phrases to cue the reader to the ways in which you are analyzing the relationship between the subjects.

After you finish analyzing the subjects, write a conclusion that summarizes the main points of the essay and reinforces your thesis. See Chapter 15 “Readings: Examples of Essays” to read a sample compare-and-contrast essay.

Many business presentations are conducted using comparison and contrast. The organizing strategies—by subject or individual points—could also be used for organizing a presentation. Keep this in mind as a way of organizing your content the next time you or a colleague have to present something at work.

Choose one of the outlines you created in Note 10.75 “Exercise 3” , and write a full compare-and-contrast essay. Be sure to include an engaging introduction, a clear thesis, well-defined and detailed paragraphs, and a fitting conclusion that ties everything together.

Key Takeaways

A compare-and-contrast essay analyzes two subjects by either comparing them, contrasting them, or both.
The purpose of writing a comparison or contrast essay is not to state the obvious but rather to illuminate subtle differences or unexpected similarities between two subjects.
The thesis should clearly state the subjects that are to be compared, contrasted, or both, and it should state what is to be learned from doing so.

There are two main organizing strategies for compare-and-contrast essays.

Organize by the subjects themselves, one then the other.
Organize by individual points, in which you discuss each subject in relation to each point.
Use phrases of comparison or phrases of contrast to signal to readers how exactly the two subjects are being analyzed.

Comparing and Contrasting: A Guide to Improve Your Essays

Walter Akolo

Essays that require you to compare and contrast two or more subjects, ideas, places, or items are common.

They call for you to highlight the key similarities (compare) and differences (contrast) between them.

This guide contains all the information you need to become better at writing comparing and contrasting essays.

This includes: how to structure your essay, how to decide on the content, and some examples of essay questions.

Let’s dive in.

What Is Comparing and Contrasting?

Is compare and contrast the same as similarities and differences, what is the purpose of comparing and contrasting, can you compare and contrast any two items, how do you compare and contrast in writing, what are some comparing and contrasting techniques, how do you compare and contrast in college level writing, the four essentials of compare and contrast essays, what can you learn from a compare and contrast essay.

At their most basic, both comparing and contrasting base their evaluation on two or more subjects that share a connection.

The subjects could have similar characteristics, features, or foundations.

But while a comparison discusses the similarities of the two subjects, e.g. a banana and a watermelon are both fruit, contrasting highlights how the subjects or items differ from each other, e.g. a watermelon is around 10 times larger than a banana.

Any question that you are asked in education will have a variety of interesting comparisons and deductions that you can make.

Compare is the same as similarities.

Contrast is the same as differences.

This is because comparing identifies the likeness between two subjects, items, or categories, while contrasting recognizes disparities between them.

When you compare things, you represent them regarding their similarity, but when you contrast things, you define them in reference to their differences.

As a result, if you are asked to discuss the similarities and differences between two subjects, you can take an identical approach to if you are writing a compare and contrast essay.

In writing, the purpose of comparing and contrasting is to highlight subtle but important differences or similarities that might not be immediately obvious.

By illustrating the differences between elements in a similar category, you help heighten readers’ understanding of the subject or topic of discussion.

For instance, you might choose to compare and contrast red wine and white wine by pointing out the subtle differences. One of these differences is that red wine is best served at room temperature while white is best served chilled.

Also, comparing and contrasting helps to make abstract ideas more definite and minimizes the confusion that might exist between two related concepts.

Can Comparing and Contrasting Be Useful Outside of Academia?

Comparing enables you to see the pros and cons, allowing you to have a better understanding of the things under discussion. In an essay, this helps you demonstrate that you understand the nuances of your topic enough to draw meaningful conclusions from them.

Let's use a real-word example to see the benefits. Imagine you're contrasting two dresses you could buy. You might think:

Dress A is purple, my favorite color, but it has a difficult zip and is practically impossible to match a jacket to.
Dress B is more expensive but I already have a suitable pair of shoes and jacket and it is easier to move in.

You're linking the qualities of each dress to the context of the decision you're making. This is the same for your essay. Your comparison and contrast points will be in relation to the question you need to answer.

Comparing and contrasting is only a useful technique when applied to two related concepts.

To effectively compare two or more things, they must feature characteristics similar enough to warrant comparison.

In addition to this they must also feature a similarity that generates an interesting discussion. But what do I mean by “interesting” here?

Let’s look at two concepts, the Magna Carta and my third grade poetry competition entry.

They are both text, written on paper by a person so they fulfil the first requirement, they have a similarity. But this comparison clearly would not fulfil the second requirement, you would not be able to draw any interesting conclusions.

However, if we compare the Magna Carta to the Bill of Rights, you would be able to come to some very interesting conclusions concerning the history of world politics.

To write a good compare and contrast essay, it’s best to pick two or more topics that share a meaningful connection .

The aim of the essay would be to show the subtle differences or unforeseen similarities.

By highlighting the distinctions between elements in a similar category you can increase your readers’ understanding.

Alternatively, you could choose to focus on a comparison between two subjects that initially appear unrelated.

The more dissimilar they seem, the more interesting the comparison essay will turn out.

For instance, you could compare and contrast professional rugby players with marathon runners.

Can You Compare and Contrast in an Essay That Does Not Specifically Require It?

As a writer, you can employ comparing and contrasting techniques in your writing, particularly when looking for ideas you can later apply in your argument.

You can do this even when the comparison or contrast is not a requirement for the topic or argument you are presenting. Doing so could enable you to build your evaluation and develop a stronger argument.

Note that the similarities and differences you come up with might not even show up in the final draft.

While the use of compare and contrast can be neutral, you can also use it to highlight one option under discussion. When used this way, you can influence the perceived advantages of your preferred option.

As a writing style, comparing and contrasting can encompass an entire essay. However, it could also appear in some select paragraphs within the essay, where making some comparisons serves to better illustrate a point.

What Should You Do First?

Before you compare two things, always start by deciding on the reason for your comparison, then outline the criteria you will use to compare them.

Words and phrases commonly used for comparison include:

In writing, these words and phrases are called transitions . They help readers to understand or make the connection between sentences, paragraphs, and ideas.

Without transition words writing can feel clumsy and disjointed making it difficult to read. ProWritingAid’s transition report highlights all of a documents transitions and suggests that 25% of any sentences in a piece include a transition.

So, how do you form all of this into a coherent essay? It's a good idea to plan first, then decide what your paragraph layout will look like.

Venn diagrams are useful tool to start generating ideas. The, for your essay, you need to choose between going idea by idea and going point by point.

Using a Venn Diagram

A Venn diagram helps you to clearly see the similarities and differences between multiple objects, things, or subjects.

The writing tool comprises two, or more, simple, overlapping circles in which you list down the things that are alike (within the overlapping area) and those that differ (outside the overlapping area).

It’s great for brainstorming ideas and for creating your essay’s outline. You could even use it in an exam setting because it is quick and simple.

Going Subject by Subject

Going subject by subject is a structural choice for your essay.

Start by saying all you have to say on the first subject, then proceed to do the same about the second subject.

Depending on the length of your essay, you can fit the points about each subject into one paragraph or have several sections per each subject, ending with a conclusion.

This method is best for short essays on simple topics. Most university-level essays will go point by point instead.

Going Point by Point

Going point by point, or alternating, is the opposite essay structure from going subject by subject. This is ideal when you want to do more direct comparing and contrasting. It entails discussing one comparison point at a time. It allows you to use a paragraph to talk about how a certain comparing/contrasting point relates to the subjects or items you are discussing.

Alternatively, if you have lots of details about the subject, you might decide to use a paragraph for each point.

An academic compare and contrast essay looks at two or more subjects, ideas, people, or objects, compares their likeness, and contrasts their differences.

It’s an informative essay that provides insights on what is similar and different between the two items.

Depending on the essay’s instructions, you can focus solely on comparing or contrasting, or a combination of the two.

Examples of College Level Compare and Contrast Essay Questions

Here are eleven examples of compare and contrast essay questions that you might encounter at university:

Archaeology: Compare and contrast the skulls of homo habilis, homo erectus, and homo sapiens.
Art: Compare and contrast the working styles of any two Neoclassic artists.
Astrophysics: Compare and contrast the chemical composition of Venus and Neptune.
Biology: Compare and contrast the theories of Lamarck and Darwin.
Business: Compare and contrast 2 or more business models within the agricultural industry.
Creative writing: Compare and contrast free indirect discourse with epistolary styles.
English Literature: Compare and contrast William Wordsworth with Robert Browning.
Geography: Compare and contrast the benefit of solar panels with the benefit of wind turbines.
History: Compare and contrast WWI to WWII with specific reference to the causes and outcomes.
Medicine: Compare and contrast England’s health service with America’s health service.
Psychology: Compare and contrast the behaviorist theory with the psychodynamic theory.

So, the key takeaways to keep in mind are:

Have a basis for comparison. The two things need to have enough in common to justify a discussion about their similarities and disparities.

Don’t go back and forth when using the block method. The best way to write your essay is to begin with a paragraph discussing all the facets of the first topic. Then, move on to another paragraph and talk through all the aspects of the second subject.

You can use both alternating and blocking techniques. Combining the two approaches is also an option. You can apply the alternating method in some paragraphs, then switch and use the block method. This method will help you offer a much deeper analysis of the subjects.

Have a reason for comparing the two things. Only select the points of comparison that resonate with your purpose.

Comparing and contrasting are essential analytical skills in academic writing. When your professor issues you with such an essay, their primary goal is to teach you how to:

Engage in critical thinking
See and make connections between words or ideas
Move beyond mere descriptions or summaries to developing interesting analysis
Get a deeper understanding of the subjects or items under comparison, their key features, and their interrelationships with each other.

The benefits of comparing and contrasting

Ultimately, your essay should enlighten readers by providing useful information.

Writing for Success: Compare/Contrast

LEARNING OBJECTIVES

This section will help you determine the purpose and structure of comparison/contrast in writing.

The Purpose of Compare/Contrast in Writing

Comparison in writing discusses elements that are similar, while contrast in writing discusses elements that are different. A compare-and-contrast essay, then, analyzes two subjects by comparing them, contrasting them, or both.

The Structure of a Compare/Contrast Essay

Thesis Statement: Organic vegetables may cost more than those that are conventionally grown, but when put to the test, they are definitely worth every extra penny.

Here the thesis sets up the two subjects to be compared and contrasted (organic versus conventional vegetables), and it makes a claim about the results that might prove useful to the reader.

You may organize compare-and-contrast essays in one of the following two ways:

According to the subjects themselves, discussing one then the other
According to individual points, discussing each subject in relation to each point

The organizational structure you choose depends on the nature of the topic, your purpose, and your audience.

Given that compare-and-contrast essays analyze the relationship between two subjects, it is helpful to have some phrases on hand that will cue the reader to such analysis.

Phrases of Comparison and Contrast


one similarity	one difference
another similarity	another difference
both	conversely
like	in contrast
likewise	unlike
similarly	while
in a similar fashion	whereas

Writing an Compare/Contrast Essay

After you finish analyzing the subjects, write a conclusion that summarizes the main points of the essay and reinforces your thesis.

Compare/Contrast Essay Example

Comparing and Contrasting London and Washington, DC

By Scott McLean in Writing for Success

Both Washington, DC, and London are capital cities of English-speaking countries, and yet they offer vastly different experiences to their residents and visitors. Comparing and contrasting the two cities based on their history, their culture, and their residents show how different and similar the two are.

Both cities are rich in world and national history, though they developed on very different time lines. London, for example, has a history that dates back over two thousand years. It was part of the Roman Empire and known by the similar name, Londinium. It was not only one of the northernmost points of the Roman Empire but also the epicenter of the British Empire where it held significant global influence from the early sixteenth century on through the early twentieth century. Washington, DC, on the other hand, has only formally existed since the late eighteenth century. Though Native Americans inhabited the land several thousand years earlier, and settlers inhabited the land as early as the sixteenth century, the city did not become the capital of the United States until the 1790s. From that point onward to today, however, Washington, DC, has increasingly maintained significant global influence. Even though both cities have different histories, they have both held, and continue to hold, significant social influence in the economic and cultural global spheres.

Both Washington, DC, and London offer a wide array of museums that harbor many of the world’s most prized treasures. While Washington, DC, has the National Gallery of Art and several other Smithsonian galleries, London’s art scene and galleries have a definite edge in this category. From the Tate Modern to the British National Gallery, London’s art ranks among the world’s best. This difference and advantage has much to do with London and Britain’s historical depth compared to that of the United States. London has a much richer past than Washington, DC, and consequently has a lot more material to pull from when arranging its collections. Both cities have thriving theater districts, but again, London wins this comparison, too, both in quantity and quality of theater choices. With regard to other cultural places like restaurants, pubs, and bars, both cities are very comparable. Both have a wide selection of expensive, elegant restaurants as well as a similar amount of global and national chains. While London may be better known for its pubs and taste in beer, DC offers a different bar-going experience. With clubs and pubs that tend to stay open later than their British counterparts, the DC night life tend to be less reserved overall.

Both cities also share and differ in cultural diversity and cost of living. Both cities share a very expensive cost of living—both in terms of housing and shopping. A downtown one-bedroom apartment in DC can easily cost $1,800 per month, and a similar “flat” in London may double that amount. These high costs create socioeconomic disparity among the residents. Although both cities’ residents are predominantly wealthy, both have a significantly large population of poor and homeless. Perhaps the most significant difference between the resident demographics is the racial makeup. Washington, DC, is a “minority majority” city, which means the majority of its citizens are races other than white. In 2009, according to the US Census, 55 percent of DC residents were classified as “Black or African American” and 35 percent of its residents were classified as “white.” London, by contrast, has very few minorities—in 2006, 70 percent of its population was “white,” while only 10 percent was “black.” The racial demographic differences between the cities is drastic.

Even though Washington, DC, and London are major capital cities of English-speaking countries in the Western world, they have many differences along with their similarities. They have vastly different histories, art cultures, and racial demographics, but they remain similar in their cost of living and socioeconomic disparity.

KEY TAKEAWAYS

A compare-and-contrast essay analyzes two subjects by either comparing them, contrasting them, or both.
The purpose of writing a comparison or contrast essay is not to state the obvious but rather to illuminate subtle differences or unexpected similarities between two subjects.
The thesis should clearly state the subjects that are to be compared, contrasted, or both, and it should state what is to be learned from doing so.
There are two main organizing strategies for compare-and-contrast essays.
Organize by the subjects themselves, one then the other.
Organize by individual points, in which you discuss each subject in relation to each point.
Use phrases of comparison or phrases of contrast to signal to readers how exactly the two subjects are being analyzed.

How to Write a Comparative Essay – A Complete Guide

10 min read

What is a Comparative Essay?

A comparative essay is a type of essay in which an essay writer compares at least two or more items. The author compares two subjects with the same relation in terms of similarities and differences depending on the assignment.

The main purpose of the comparative essay is to:

Highlight the similarities and differences in a systematic manner.
Provide great clarity of the subject to the readers.
Analyze two things and describe their advantages and drawbacks.

A comparative essay is also known as compare and contrast essay or a comparison essay. It analyzes two subjects by either comparing them, contrasting them, or both. The Venn diagram is the best tool for writing a paper about the comparison between two subjects.

Moreover, a comparative analysis essay discusses the similarities and differences of themes, items, events, views, places, concepts, etc. For example, you can compare two different novels (e.g., The Adventures of Huckleberry Finn and The Red Badge of Courage).

However, a comparative essay is not limited to specific topics. It covers almost every topic or subject with some relation.

Comparative Essay Structure

A good comparative essay is based on how well you structure your essay. It helps the reader to understand your essay better.

The structure is more important than what you write. This is because it is necessary to organize your essay so that the reader can easily go through the comparisons made in an essay.

The following are the two main methods in which you can organize your comparative essay.

Point-by-Point Method

The point-by-point or alternating method provides a detailed overview of the items that you are comparing. In this method, organize items in terms of similarities and differences.

This method makes the writing phase easy for the writer to handle two completely different essay subjects. It is highly recommended where some depth and detail are required.

Below given is the structure of the point-by-point method.

Block Method

The block method is the easiest as compared to the point-by-point method. In this method, you divide the information in terms of parameters. It means that the first paragraph compares the first subject and all their items, then the second one compares the second, and so on.

However, make sure that you write the subject in the same order. This method is best for lengthy essays and complicated subjects.

Here is the structure of the block method.

Therefore, keep these methods in mind and choose the one according to the chosen subject.

Mixed Paragraphs Method

In this method, one paragraph explains one aspect of the subject. As a writer, you will handle one point at a time and one by one. This method is quite beneficial as it allows you to give equal weightage to each subject and help the readers identify the point of comparison easily.

How to Start a Comparative Essay?

Here, we have gathered some steps that you should follow to start a well-written comparative essay.

Choose a Topic

The foremost step in writing a comparative essay is to choose a suitable topic.

Choose a topic or theme that is interesting to write about and appeals to the reader.

An interesting essay topic motivates the reader to know about the subject. Also, try to avoid complicated topics for your comparative essay.

Develop a List of Similarities and Differences

Create a list of similarities and differences between two subjects that you want to include in the essay. Moreover, this list helps you decide the basis of your comparison by constructing your initial plan.

Evaluate the list and establish your argument and thesis statement .

Establish the Basis for Comparison

The basis for comparison is the ground for you to compare the subjects. In most cases, it is assigned to you, so check your assignment or prompt.

Furthermore, the main goal of the comparison essay is to inform the reader of something interesting. It means that your subject must be unique to make your argument interesting.

Do the Research

In this step, you have to gather information for your subject. If your comparative essay is about social issues, historical events, or science-related topics, you must do in-depth research.

However, make sure that you gather data from credible sources and cite them properly in the essay.

Create an Outline

An essay outline serves as a roadmap for your essay, organizing key elements into a structured format.

With your topic, list of comparisons, basis for comparison, and research in hand, the next step is to create a comprehensive outline.

Here is a standard comparative essay outline:

Subject A

Subject B

Analysis

Subject A

Subject B

Analysis

How to Write a Comparative Essay?

Now that you have the basic information organized in an outline, you can get started on the writing process.

Here are the essential parts of a comparative essay:

Comparative Essay Introduction

Start off by grabbing your reader's attention in the introduction . Use something catchy, like a quote, question, or interesting fact about your subjects.

Then, give a quick background so your reader knows what's going on.

The most important part is your thesis statement, where you state the main argument , the basis for comparison, and why the comparison is significant.

This is what a typical thesis statement for a comparative essay looks like:

Comparative Essay Body Paragraphs

The body paragraphs are where you really get into the details of your subjects. Each paragraph should focus on one thing you're comparing.

Start by talking about the first point of comparison. Then, go on to the next points. Make sure to talk about two to three differences to give a good picture.

After that, switch gears and talk about the things they have in common. Just like you discussed three differences, try to cover three similarities.

This way, your essay stays balanced and fair. This approach helps your reader understand both the ways your subjects are different and the ways they are similar. Keep it simple and clear for a strong essay.

Comparative Essay Conclusion

In your conclusion , bring together the key insights from your analysis to create a strong and impactful closing.

Consider the broader context or implications of the subjects' differences and similarities. What do these insights reveal about the broader themes or ideas you're exploring?

Discuss the broader implications of these findings and restate your thesis. Avoid introducing new information and end with a thought-provoking statement that leaves a lasting impression.

Below is the detailed comparative essay template format for you to understand better.

Compare & Contrast Essays How things are similar or different

Compare and contrast is a common form of academic writing, either as an essay type on its own, or as part of a larger essay which includes one or more paragraphs which compare or contrast. This page gives information on what a compare and contrast essay is , how to structure this type of essay, how to use compare and contrast structure words , and how to make sure you use appropriate criteria for comparison/contrast . There is also an example compare and contrast essay on the topic of communication technology, as well as some exercises to help you practice this area.

What are compare & contrast essays?

For another look at the same content, check out YouTube » or Youku » , or this infographic » .

To compare is to examine how things are similar, while to contrast is to see how they differ. A compare and contrast essay therefore looks at the similarities of two or more objects, and the differences. This essay type is common at university, where lecturers frequently test your understanding by asking you to compare and contrast two theories, two methods, two historical periods, two characters in a novel, etc. Sometimes the whole essay will compare and contrast, though sometimes the comparison or contrast may be only part of the essay. It is also possible, especially for short exam essays, that only the similarities or the differences, not both, will be discussed. See the examples below.

Compare and contrast Newton's ideas of gravity with those proposed by Einstein ['compare and contrast' essay]
Examine how the economies of Spain and China are similar ['compare' only essay]
Explain the differences between Achaemenid Empire and Parthian Empire ['contrast' only essay]

There are two main ways to structure a compare and contrast essay, namely using a block or a point-by-point structure. For the block structure, all of the information about one of the objects being compared/contrasted is given first, and all of the information about the other object is listed afterwards. This type of structure is similar to the block structure used for cause and effect and problem-solution essays. For the point-by-point structure, each similarity (or difference) for one object is followed immediately by the similarity (or difference) for the other. Both types of structure have their merits. The former is easier to write, while the latter is generally clearer as it ensures that the similarities/differences are more explicit.

The two types of structure, block and point-by-point , are shown in the diagram below.

Compare and Contrast Structure Words

Compare and contrast structure words are transition signals which show the similarities or differences. Below are some common examples.

both... and...
not only... but also...
neither... nor...
just like (+ noun)
similar to (+ noun)
to be similar (to)
to be the same as
to be alike
to compare (to/with)
Computers can be used to communicate easily, for example via email. Similarly/Likewise , the mobile phone is a convenient tool for communication.
Both computers and mobile phones can be used to communicate easily with other people.
Just like the computer, the mobile phone can be used to communicate easily with other people.
The computer is similar to the mobile phone in the way it can be used for easy communication.
In contrast
In comparison
By comparison
On the other hand
to differ from
to be different (from)
to be dissimilar to
to be unlike
Computers, although increasingly small, are not always easy to carry from one place to another. However , the mobile phone can be carried with ease.
Computers are generally not very portable, whereas the mobile phone is.
Computers differ from mobile phones in their lack of portability.
Computers are unlike mobile phones in their lack of portability.

Criteria for comparison/contrast

When making comparisons or contrasts, it is important to be clear what criteria you are using. Study the following example, which contrasts two people. Here the criteria are unclear.

Aaron is tall and strong. In contrast , Bruce is handsome and very intelligent.

Although this sentence has a contrast transition , the criteria for contrasting are not the same. The criteria used for Aaron are height (tall) and strength (strong). We would expect similar criteria to be used for Bruce (maybe he is short and weak), but instead we have new criteria, namely appearance (handsome) and intelligence (intelligent). This is a common mistake for students when writing this type of paragraph or essay. Compare the following, which has much clearer criteria (contrast structure words shown in bold).

Aaron and Bruce differ in four ways. The first difference is height. Aaron is tall, while Bruce is short. A second difference is strength. Aaron is strong. In contrast , Bruce is weak. A third difference is appearance. Aaron, who is average looking, differs from Bruce, who is handsome. The final difference is intelligence. Aaron is of average intelligence. Bruce, on the other hand , is very intelligent.

Example essay

Below is a compare and contrast essay. This essay uses the point-by-point structure . Click on the different areas (in the shaded boxes to the right) to highlight the different structural aspects in this essay, i.e. similarities, differences, and structure words. This will highlight not simply the paragraphs, but also the thesis statement and summary , as these repeat the comparisons and contrasts contained in the main body.

Title: There have been many advances in technology over the past fifty years. These have revolutionised the way we communicate with people who are far away. Compare and contrast methods of communication used today with those which were used in the past.

Before the advent of computers and modern technology, people communicating over long distances used traditional means such as letters and the telephone. Nowadays we have a vast array of communication tools which can complete this task, ranging from email to instant messaging and video calls. While the present and previous means of communication are similar in their general form , they differ in regard to their speed and the range of tools available . One similarity between current and previous methods of communication relates to the form of communication. In the past, both written forms such as letters were frequently used, in addition to oral forms such as telephone calls. Similarly , people nowadays use both of these forms. Just as in the past, written forms of communication are prevalent, for example via email and text messaging. In addition, oral forms are still used, including the telephone, mobile phone, and voice messages via instant messaging services. However , there are clearly many differences in the way we communicate over long distances, the most notable of which is speed. This is most evident in relation to written forms of communication. In the past, letters would take days to arrive at their destination. In contrast , an email arrives almost instantaneously and can be read seconds after it was sent. In the past, if it was necessary to send a short message, for example at work, a memo could be passed around the office, which would take some time to circulate. This is different from the current situation, in which a text message can be sent immediately. Another significant difference is the range of communication methods. Fifty years ago, the tools available for communicating over long distances were primarily the telephone and the letter. By comparison , there are a vast array of communication methods available today. These include not only the telephone, letter, email and text messages already mentioned, but also video conferences via software such as Skype or mobile phone apps such as WeChat, and social media such as Facebook and Twitter. In conclusion, methods of communication have greatly advanced over the past fifty years. While there are some similarities, such as the forms of communication , there are significant differences, chiefly in relation to the speed of communication and the range of communication tools available . There is no doubt that technology will continue to progress in future, and the advanced tools which we use today may one day also become outdated.

Compare & contrast essays examine the similarities of two or more objects, and the differences.

Cause & effect essays consider the reasons (or causes) for something, then discuss the results (or effects).

Discussion essays require you to examine both sides of a situation and to conclude by saying which side you favour.

Problem-solution essays are a sub-type of SPSE essays (Situation, Problem, Solution, Evaluation).

Transition signals are useful in achieving good cohesion and coherence in your writing.

The purpose of a compare and contrast essay is to analyze the differences and/or the similarities of two distinct subjects. A good compare/contrast essay doesn’t only point out how the subjects are similar or different (or even both!). It uses those points to make a meaningful argument about the subjects. While it can be a little intimidating to approach this type of essay at first, with a little work and practice, you can write a great compare-and-contrast essay!

Formulating Your Argument

Step 1 Pick two subjects that can be compared and contrasted.

You could pick two subjects that are in the same “category” but have differences that are significant in some way. For example, you could choose “homemade pizza vs. frozen grocery store pizza.”
You could pick two subjects that don’t appear to have anything in common but that have a surprising similarity. For example, you could choose to compare bats and whales. (One is tiny and flies, and the other is huge and swims, but they both use sonar to hunt.)
You could pick two subjects that might appear to be the same but are actually different. For example, you could choose "The Hunger Games movie vs. the book."

Step 2 Make sure that your subjects can be discussed in a meaningful way.

For example, ask yourself: What can we learn by thinking about “The Hunger Games” and “Battle Royale” together that we would miss out on if we thought about them separately?
It can be helpful to consider the “So what?” question when deciding whether your subjects have meaningful comparisons and contrasts to be made. If you say “The Hunger Games and Battle Royale are both similar and different,” and your friend asked you “So what?” what would your answer be? In other words, why bother putting these two things together?

A “Venn diagram” can often be helpful when brainstorming. This set of overlapping circles can help you visualize where your subjects are similar and where they differ. In the outer edges of the circle, you write what is different; in the overlapping middle area, you write what’s similar. [2] X Trustworthy Source University of North Carolina Writing Center UNC's on-campus and online instructional service that provides assistance to students, faculty, and others during the writing process Go to source
You can also just draw out a list of all of the qualities or characteristics of each subject. Once you’ve done that, start looking through the list for traits that both subjects share. Major points of difference are also good to note.

For example, if you are comparing and contrasting cats and dogs, you might notice that both are common household pets, fairly easy to adopt, and don’t usually have many special care needs. These are points of comparison (ways they are similar).
You might also note that cats are usually more independent than dogs, that dogs may not provoke allergies as much as cats do, and that cats don’t get as big as many dogs do. These are points of contrast (ways they are different).
These points of contrast can often be good places to start thinking about your thesis, or argument. Do these differences make one animal a superior type of pet? Or a better pet choice for a specific living situation (e.g., an apartment, a farm, etc.)?

Show readers why one subject is more desirable than the other. Example: "Cats are better pets than dogs because they require less maintenance, are more independent, and are more adaptable."
Help readers make a meaningful comparison between two subjects. Example: "New York City and San Francisco are both great cities for young professionals, but they differ in terms of their job opportunities, social environment, and living conditions."
Show readers how two subjects are similar and different. Example: "While both The Catcher in the Rye and To Kill a Mockingbird explore the themes of loss of innocence and the deep bond between siblings, To Kill a Mockingbird is more concerned with racism while The Catcher in the Rye focuses on the prejudices of class."
In middle school and high school, the standard format for essays is often the “5-paragraph form,” with an introduction, 3 body paragraphs, and a conclusion. If your teacher recommends this form, go for it. However, you should be aware that especially in college, teachers and professors tend to want students to break out of this limited mode. Don’t get so locked into having “three main points” that you forget to fully explore your topic.

Organizing Your Essay

Subject by subject. This organization deals with all of the points about Topic A, then all of the points of Topic B. For example, you could discuss all your points about frozen pizza (in as many paragraphs as necessary), then all your points about homemade pizza. The strength of this form is that you don’t jump back and forth as much between topics, which can help your essay read more smoothly. It can also be helpful if you are using one subject as a “lens” through which to examine the other. The major disadvantage is that the comparisons and contrasts don’t really become evident until much further into the essay, and it can end up reading like a list of “points” rather than a cohesive essay. [4] X Trustworthy Source University of North Carolina Writing Center UNC's on-campus and online instructional service that provides assistance to students, faculty, and others during the writing process Go to source
Point by point. This type of organization switches back and forth between points. For example, you could first discuss the prices of frozen pizza vs. homemade pizza, then the quality of ingredients, then the convenience factor. The advantage of this form is that it’s very clear what you’re comparing and contrasting. The disadvantage is that you do switch back and forth between topics, so you need to make sure that you use transitions and signposts to lead your reader through your argument.
Compare then contrast. This organization presents all the comparisons first, then all the contrasts. It’s a pretty common way of organizing an essay, and it can be helpful if you really want to emphasize how your subjects are different. Putting the contrasts last places the emphasis on them. However, it can be more difficult for your readers to immediately see why these two subjects are being contrasted if all the similarities are first.

Introduction. This paragraph comes first and presents the basic information about the subjects to be compared and contrasted. It should present your thesis and the direction of your essay (i.e., what you will discuss and why your readers should care).
Body Paragraphs. These are the meat of your essay, where you provide the details and evidence that support your claims. Each different section or body paragraph should tackle a different division of proof. It should provide and analyze evidence in order to connect those proofs to your thesis and support your thesis. Many middle-school and high-school essays may only require three body paragraphs, but use as many as is necessary to fully convey your argument.
Acknowledgement of Competitive Arguments/Concession. This paragraph acknowledges that other counter-arguments exist, but discusses how those arguments are flawed or do not apply.
Conclusion. This paragraph summarizes the evidence presented. It will restate the thesis, but usually in a way that offers more information or sophistication than the introduction could. Remember: your audience now has all the information you gave them about why your argument is solid. They don’t need you to just reword your original thesis. Take it to the next level!

Step 3 Outline your body paragraphs based on subject-to-subject comparison.

Introduction: state your intent to discuss the differences between camping in the woods or on the beach.
Body Paragraph 1 (Woods): Climate/Weather
Body Paragraph 2 (Woods): Types of Activities and Facilities
Body Paragraph 3 (Beach): Climate/Weather
Body Paragraph 4 (Beach): Types of Activities and Facilities

Step 4 Outline your body paragraphs based on point-by-point comparison.

Introduction

Step 5 Outline your body paragraphs based on compare then contrast.

Body Paragraph 1: Similarity between woods and beaches (both are places with a wide variety of things to do)
Body Paragraph 2: First difference between woods and beaches (they have different climates)
Body Paragraph 3: Second difference between woods and beaches (there are more easily accessible woods than beaches in most parts of the country)
Body Paragraph 4: Emphasis on the superiority of the woods to the beach

Step 6 Organize your individual body paragraphs.

Topic sentence: This sentence introduces the main idea and subject of the paragraph. It can also provide a transition from the ideas in the previous paragraph.
Body: These sentences provide concrete evidence that support the topic sentence and main idea.
Conclusion: this sentence wraps up the ideas in the paragraph. It may also provide a link to the next paragraph’s ideas.

Putting It All Together

Step 1 Use your brainstorming ideas to fill in your outline.

If you are having trouble finding evidence to support your argument, go back to your original texts and try the brainstorming process again. It could be that your argument is evolving past where it started, which is good! You just need to go back and look for further evidence.

For example, in a body paragraph about the quality of ingredients in frozen vs. homemade pizza, you could close with an assertion like this: “Because you actively control the quality of the ingredients in pizza you make at home, it can be healthier for you than frozen pizza. It can also let you express your imagination. Pineapple and peanut butter pizza? Go for it! Pickles and parmesan? Do it! Using your own ingredients lets you have fun with your food.” This type of comment helps your reader understand why the ability to choose your own ingredients makes homemade pizza better.

Reading your essay aloud can also help you find problem spots. Often, when you’re writing you get so used to what you meant to say that you don’t read what you actually said.

Avoid bias. Don't use overly negative or defamatory language to show why a subject is unfavorable; use solid evidence to prove your points instead.
Avoid first-person pronouns unless told otherwise. In some cases, your teacher may encourage you to use “I” and “you” in your essay. However, if the assignment or your teacher doesn’t mention it, stick with third-person instead, like “one may see” or “people may enjoy.” This is common practice for formal academic essays.
Proofread! Spelling and punctuation errors happen to everyone, but not catching them can make you seem lazy. Go over your essay carefully, and ask a friend to help if you’re not confident in your own proofreading skills.

Sample Body Paragraphs

Step 1 Write a body paragraph for a point-by-point compare and contrast essay.

"When one is deciding whether to go to the beach or the woods, the type of activities that each location offers are an important point to consider. At the beach, one can enjoy the water by swimming, surfing, or even building a sandcastle with a moat that will fill with water. When one is in the woods, one may be able to go fishing or swimming in a nearby lake, or one may not be near water at all. At the beach, one can keep one's kids entertained by burying them in sand or kicking around a soccer ball; if one is in the woods, one can entertain one's kids by showing them different plans or animals. Both the beach and the woods offer a variety of activities for adults and kids alike."

Step 2 Write a body paragraph for a subject-by-subject compare and contrast essay.

"The beach has a wonderful climate, many activities, and great facilities for any visitor's everyday use. If a person goes to the beach during the right day or time of year, he or she can enjoy warm, yet refreshing water, a cool breeze, and a relatively hot climate. At the beach, one can go swimming, sunbathe, or build sandcastles. There are also great facilities at the beach, such as a changing room, umbrellas, and conveniently-located restaurants and changing facilities. The climate, activities, and facilities are important points to consider when deciding between the beach and the woods."

To use the point-by-point method, come up with one main idea for each body paragraph. Discuss both of your subjects within each body paragraph by comparing and contrasting them in relation to paragraph's main point.

What is a good introduction for a compare and contrast essay?

A good introduction for a compare and contrast essay begins with an attention-getter, introduces the two subjects that will be compared and contrasted, gives a preview of the main points that will be discussed in the body paragraphs, and ends with a thesis statement.

How do you write a compare and contrast essay outline?

A compare and contrast essay outline should contain introduction, body, and concluding paragraphs. The exact outline depends on the method of organization that is used.

The point-by-point method uses a standard five-paragraph essay structure:

Introduction (contains the attention-getter, preview of main points, and thesis)
Body paragraph 1 (main idea #1 as it relates to both subjects)
Body paragraph 2 (main idea #2 as it relates to both subjects)
Body paragraph 3 (main idea #3 as it relates to both subjects)
Conclusion (restates thesis, summarizes main point, leaves reader with a lingering thought)

The block method uses a four-paragraph structure:

Body paragraph 1 (main ideas for subject #1)
Body paragraph 2 (main ideas for subject #2)

A compare and contrast essay is an essay that discusses or explains the similarities and differences between two subjects. Sometimes the guidelines for a compare and contrast essay will state which two subjects should be compared and contrasted, such as two stories which were read in class. Other times, it is left up to the student to decide which subjects to compare and contrast. In this case, it is best if the two subjects are from the same category like two books, two films, two animals, two sports, or two songs. It would be much more difficult to compare two subjects that belong to totally different categories, like Shakespeare and a zebra.

When choosing a topic, pick a subject that is interesting to you. It is easiest to write about topics that you are interested in, and it is helpful to already know a little bit about the topic in advance so that you can spend your time writing rather than researching. You should also give some thought to whether the topic will be interesting to your reader, likely your teacher. An interesting topic is not usually a requirement of a compare and contrast essay, but an essay that is interesting or entertaining to read will likely reflect that in the essay's final grade.

Compare and Contrast Essay Structure

To compare is to explain the similarities between two subjects. To contrast is to explain the differences between two subjects. These similarities and differences will become the main ideas of your body paragraphs. When choosing which similarities and differences to discuss in your essay, be sure they are significant or thought-provoking. The goal of your essay should be to leave the reader with a new outlook on your subjects, not to tell them information they already know.

There are two methods of organization that may be used to arrange your ideas within the body paragraphs, the point-by-point method and the block method:

For the point-by-point method , each body body paragraph discusses one main idea in relation to both subjects. For example, pretend you are writing an essay comparing and contrasting two types of birds. The main idea of the first body paragraph may be the physical appearances of both birds, the main idea of the second body paragraph may be the diets of both birds, and the third body paragraph's main idea may be the habitats of both birds. This method works well with a five-paragraph essay structure. However, it may be difficult to seamlessly switch back and forth between subjects in each paragraph.
The block method uses only two body paragraphs. Each body paragraph is devoted to discussing one of the subjects. For example, if you are writing an essay comparing and contrasting middle school and high school, the first body paragraph would address all of the main ideas related to middle school. The second body paragraph would discuss all of the main ideas related to high school. This method is probably the easier of the two methods since you discuss one subject at a time, but it results in only two body paragraphs. If you are required to write a five-paragraph essay, choose previous point-by-point method.

Despite which method or organization you use, the order of your main points is the same: your strongest point comes last, your second strongest point comes first, and your weakest point goes in the middle. So, if you are using the point-by-point method, arrange your paragraphs with your strongest point in the third body paragraph, your second strongest point in the first body paragraph, and your weakest point in the second body paragraph. If you are using the block method, place your strongest point as the last main idea in the body paragraph, the second strongest point as the first main idea, and the weakest point in the middle of the body paragraph. The reasoning behind this is simple. You are sandwiching your weakest point between the two strongest points so that your essay is compelling at the beginning and at the end.

How to Start a Compare and Contrast Essay

A thesis statement is the guiding argument, hypothesis, or theory for your entire essay. It may be one or two sentences and it is placed at the end of the introduction. Although the thesis statement comes last in the introduction, it should be the first sentence you come up with when drafting your essay. The rest of the essay will support, clarify, or explain the presumption you make in your thesis statement, so it is imperative that you draft the thesis at the outset. For a compare and contrast essay about California and New York, a passable thesis statement could be "California and New York are two states with many differences, but despite being located at opposite ends of the country, they have more similarities than one might expect."
The attention-getter (also called the attention-grabber, hook, or hook sentence) is the first sentence in the introduction. Like the headlines of "clickbait" articles, the purpose of the attention getter is to capture the interest of the reader. A relevant rhetorical question, little-known fact, joke, or famous quotation can be used as the attention getter. An attention getter for the essay on California and New York could be "Two places located nearly 3,000 miles apart would obviously have many differences, but could they have any similarities?"
The middle of your introduction should introduce the two subjects that will be compared and contrasted and give a preview of the main points that will be discussed in the body paragraphs.

Compare and Contrast Paragraphs

As mentioned above, the structure and content of the body paragraphs will depend on which method, point-by-point or block, is used. However, body paragraphs should contain these elements regardless of which method is used.

The topic sentence is the first sentence of a body paragraph, and as the name implies, it states the topic, main idea, or subject that is discussed in the paragraph.
Transitions such as first , second , and third should be used to separate ideas. Other possible transitions include another , for example , also , and lastly .
The concluding sentence is the last sentence of a body paragraph. It should bridge the gap between one body paragraph and the next by summing up the main point of the body paragraph that it is a part of while also hinting at the main point of the next body paragraph.

Compare and Contrast Essay Conclusion

Restate the thesis by using different words and a different sentence structure to reiterate the assertion you make in your thesis statement. Oftentimes, this sentence is begun with a transition that signals that this is the end of the essay. It might look like "All in all, California and New York have many differences, but they have a surprising number of similarities too."
Summarize the main points made in the body of the essay.
End the essay with a lingering thought . Whereas the attention getter draws the reader in, the lingering thought gives the reader something to continue to ponder after reading the essay. An example is "Considering the similarities and differences, in which state would you prefer to live?"

A map of the United States

Below is a body paragraph from a sample compare and contrast essay from Lumen Learning at lumenlearning.com. Notice how it uses the point-by-point method to compare and contrast the cultural diversity and cost of living in Washington, D.C., and London.

"Both cities are rich in world and national history, though they developed on very different time lines. London, for example, has a history that dates back over two thousand years. It was part of the Roman Empire and known by the similar name, Londinium. It was not only one of the northernmost points of the Roman Empire but also the epicenter of the British Empire where it held significant global influence from the early sixteenth century on through the early twentieth century. Washington, DC, on the other hand, has only formally existed since the late eighteenth century. Though Native Americans inhabited the land several thousand years earlier, and settlers inhabited the land as early as the sixteenth century, the city did not become the capital of the United States until the 1790s. From that point onward to today, however, Washington, DC, has increasingly maintained significant global influence. Even though both cities have different histories, they have both held, and continue to hold, significant social influence in the economic and cultural global spheres."

The Tower of London

A compare and contrast essay discusses that similarities and differences between two subjects. The two main methods for organizing your ideas within the essay are the point-by-point method (five paragraphs) and the block method (four paragraphs). The method you choose will determine the outline of your essay, but all essays should contain an introduction that begins with an attention-getter, previews the main points, and ends with a thesis statement; body paragraphs that begin with topic sentences, explain the main ideas, and end with concluding statements; and a conclusion that restates the thesis, summarizes the main points, and leaves the reader with a lingering thought.

Video Transcript

What is a compare and contrast essay.

Have you ever been accused of comparing apples to oranges and wondered what that meant? Rachel has, and now her English teacher is asking for a compare and contrast essay.

Understanding what a compare and contrast essay is makes it much easier to write one! A compare and contrast essay is an essay in which at least two subjects (characters, themes, movies) are discussed in terms of their similarities and differences in order to describe a relationship among them.

Rachel could write a compare and contrast essay describing the similarities and differences between two rival sports teams, or two fictional characters, or two books. She could, theoretically, write a compare and contrast essay about a pencil and Thor, but compare and contrast essays work out best when the two subjects belong to the same broader category.

Let's briefly review general essay structure, then discuss what is specific to a compare and contrast essay.

Essay Structure Review

An essay is a way of organizing writing to support or prove a point, called the thesis. The most common essay structure discussed in schools is the five-paragraph essay. In this structure, the essay begins with:

An introduction that describes what the essay will be about and also states the thesis.
Three(ish) body paragraphs, each about a specific point that supports the thesis.
A conclusion that restates the thesis and supporting points.

This general essay structure can be used for a number of different purposes: to persuade, to describe, or to compare and contrast.

Compare and Contrast Structure

Now, let's discuss what is specific to a compare and contrast essay. Most people simply use the word ''compare'' when they mean both compare and contrast, but the two words actually have specific, separate, and opposite meanings.

To compare means to talk about two (or more) different things in terms of their similarities.
To contrast means to talk about two (or more) things in terms of their differences.

A good compare and contrast essay engages the reader by showing how these points enrich the way we think about the two subjects. Focus on similarities and differences that are relevant and significant.

For example, say Rachel is writing a compare and contrast essay on the two fictional characters Hamlet and Homer Simpson. Her points should go beyond the obvious or superficial. She wouldn't write an essay arguing that these two characters are similar because they are both human males, yet different because they live on different continents.

However, she might argue that they are similar because they are both motivated by their appetites and lack long-term planning skills, but are differentiated by their relationships to their families.

Keep the essay's length in mind when choosing a topic. It's better to have too much information and need to be selective, than having too little to say. Look for subjects that could have interesting, unusual, or unexpected similarities and differences.

Use a brainstorming technique such as mind mapping or a Venn diagram to help you write down and organize your ideas at this stage. Write down any points of comparison or contrast as they occur. Then, select body paragraph topics from among these points and conduct research on these.

Organizing Body Paragraphs

After choosing the topic, consider the body paragraph organization. There are two general methods for organizing your compare and contrast body paragraphs.

The block method involves having two large body paragraphs. One will be the comparison paragraph that describes all of the points of comparison between the two essay subjects. The other will be the contrast paragraph that describes all points of contrast.

The general rule for ordering paragraphs in any essay is to end on the strongest paragraph, so order the two body paragraphs accordingly.

Each of these two paragraphs will likely have 2-3 points of comparison or contrast. Organize them with the strongest point coming last, the second strongest first, and the others organized logically in between.

The point-by-point method has the standard three (or more) body paragraphs, each discussing both subjects in terms of a single point, either a comparison or a contrast. In each paragraph, discuss both subjects (Hamlet and Homer in the example), but only a single point, either a comparison or a contrast.

For ordering your paragraphs in this method, the same rule applies: you should use your strongest paragraph last and your second strongest first.

Which method you use will depend on the amount of points that you want to make, but also the kinds of points you are making. For example, if you have an uneven number of points for each side (for example, lots of comparisons but few contrasts), then use the point-by-point method, since the block method would have one really long paragraph and one really short one, in this example. Just make sure you have something meaningful to say on both the compare side and the contrast side.

Conclusion and Introduction

The conclusion of your essay will be a restatement of the points within the body paragraphs, as well as a description of how those points support the overall thesis.

We have left the description of the introduction for last because that is when you should write it: last. This section prepares the reader for the essay by introducing its contents, but you yourself won't know what you are introducing until after the essay is written.

Describe the points in the introduction and conclusion in the same order as they appear in the essay. If, in the Hamlet and Homer essay, Rachel's points come in the order of desires, planning, and family life, then they should be described in that order for her introduction and conclusion as well.

A compare and contrast essay describes a relationship between two subjects in terms of points of similarities ( comparisons ) and differences ( contrasts ).

The essay can be structured according to:

Block method —uses two paragraphs, one discussing all similarities and one discussing all differences.
Point-by-points method —uses three or more paragraphs, each of which discusses either a comparison or a contrast between both subjects.

Order body paragraphs with the strongest one last, and the second strongest first. The points discussed should contribute to a deeper understanding of both subjects.

Essay vs Composition: Deciding Between Similar Terms

When it comes to writing, it’s important to use the correct terminology to effectively communicate your message. Two terms that are often used interchangeably are “essay” and “composition.” But which one is the right word to use? The answer is both, as they refer to similar but slightly different forms of writing.

An essay is a piece of writing that presents an argument or point of view on a specific topic. It typically consists of an introduction, body paragraphs, and a conclusion. Essays can be formal or informal, and can range in length from a few paragraphs to several pages. For those who might be struggling with essay writing or just need a hand, there are essay writers for hire who specialize in crafting these types of writing.

A composition, on the other hand, is a broader term that refers to any piece of writing. It can include essays, but also encompasses other forms such as poetry, short stories, and even music. Compositions can be written for a variety of purposes, including entertainment, education, and self-expression.

Throughout this article, we’ll explore the similarities and differences between essays and compositions, as well as provide tips for writing each effectively.

Define Essay

An essay is a piece of writing that presents an argument or a point of view on a particular topic. It is typically a short piece of writing that is written in a formal style and is structured in a way that allows the reader to follow the author’s argument or point of view. Essays can be written on a wide range of topics, from politics and social issues to literature and science.

Essays are often used as a way for students to demonstrate their understanding of a particular subject or to showcase their writing skills. They are also commonly used in academic settings as a way for scholars to present their research or to engage in intellectual discourse with their peers.

Define Composition

A composition is a piece of writing that is focused on a particular topic or subject. Like an essay, it is typically written in a formal style and is structured in a way that allows the reader to follow the author’s argument or point of view. However, compositions are often longer than essays and may be more detailed and comprehensive in their coverage of a particular subject.

Compositions can take many different forms, including research papers, reports, and literary analyses. They are often used in academic and professional settings as a way for individuals to communicate their ideas and findings to others in their field.

Unlike essays, which are often focused on presenting an argument or point of view, compositions may be more focused on presenting information or exploring a particular topic in depth.

How To Properly Use The Words In A Sentence

When it comes to writing, using the correct terminology is crucial. The words “essay” and “composition” are often used interchangeably, but they actually have distinct meanings. In this section, we’ll explore how to properly use these words in a sentence.

How To Use “Essay” In A Sentence

An essay is a piece of writing that presents an argument or discusses a particular topic. When using the word “essay” in a sentence, it’s important to make sure it’s being used in the correct context. Here are a few examples:

She wrote an essay on the benefits of exercise.
His essay on climate change was well-researched and thought-provoking.
I need to finish my essay before the deadline.

As you can see, the word “essay” is typically used to refer to a specific type of writing. It’s important to use it in a way that accurately reflects its meaning.

How To Use “Composition” In A Sentence

The word “composition” can refer to a few different things when it comes to writing. It can be used to describe a piece of music or art, but in the context of writing, it typically refers to a written work. Here are a few examples of how to use “composition” in a sentence:

Her composition on the history of jazz was informative and engaging.
The professor assigned a composition on the themes of Shakespeare’s plays.
He spent hours working on his composition for the creative writing class.

Just like with “essay,” it’s important to use “composition” in a way that accurately reflects its meaning. In the context of writing, it typically refers to a written work that is structured and thoughtfully put together.

More Examples Of Essay & Composition Used In Sentences

In order to further understand the differences between an essay and a composition, it can be helpful to see how these terms are used in different contexts. Here are some examples of how these words can be used in sentences:

Examples Of Using “Essay” In A Sentence

She wrote a brilliant essay on the importance of education.
The student received an A on his essay about the effects of climate change.
He spent hours researching and writing his essay on the history of the Roman Empire.
My teacher assigned a five-page essay on the causes of the American Revolution.
She submitted her essay to the literary magazine for publication.
The essay contest had over 100 entries from around the world.
His essay was praised for its originality and insight.
The essay question asked students to analyze the symbolism in a particular poem.
She struggled to come up with a topic for her essay on modern art.
He wrote a humorous essay about his experiences as a new parent.

Examples Of Using “Composition” In A Sentence

She received a scholarship for her outstanding composition skills.
The art teacher assigned a composition that required the use of different textures and colors.
He was praised for his composition of a beautiful landscape painting.

Common Mistakes To Avoid

When it comes to writing, the terms essay and composition are often used interchangeably. However, this is a common mistake that can lead to confusion and miscommunication. Here are some of the most common mistakes people make when using essay and composition interchangeably, along with explanations of why they are incorrect:

1. Using “Essay” To Refer To Any Type Of Writing

One of the most common mistakes people make is using the term “essay” to refer to any type of writing. While essays are a type of composition, not all compositions are essays. For example, a research paper or a thesis is not an essay, but rather a different type of composition that requires a different structure and approach.

2. Using “Composition” To Refer Only To Formal Writing

Another common mistake is using the term “composition” to refer only to formal writing, such as academic papers or business reports. However, compositions can take many different forms, from creative writing to personal narratives. Using “composition” only to refer to formal writing can limit your understanding of the different types of writing that exist.

3. Confusing The Purpose Of Essays And Compositions

Essays and compositions serve different purposes, and it’s important to understand the difference. Essays are typically used to persuade or inform the reader about a specific topic, while compositions can serve a variety of purposes, such as expressing emotions, telling a story, or describing an experience. Confusing the purpose of essays and compositions can lead to writing that is ineffective or off-topic.

4. Failing To Consider The Audience And Context

Finally, one of the most common mistakes people make is failing to consider the audience and context when using essay and composition interchangeably. Different types of writing require different approaches and styles, depending on the audience and context. For example, a personal narrative written for a creative writing class will require a different approach than a business report written for a professional audience. It’s important to consider these factors when choosing the appropriate type of writing.

To avoid making these mistakes in the future, consider the purpose of your writing, the audience and context, and the appropriate type of writing for your needs. By doing so, you can ensure that your writing is effective, clear, and communicates your message to your intended audience.

Context Matters

Choosing between an essay and a composition can depend on the context in which they are used. Both terms are often used interchangeably, but the context can make a difference in the choice.

Examples Of Different Contexts

Here are some examples of different contexts and how the choice between essay and composition might change:

Academic Writing: In academic writing, the term “essay” is often used to refer to a short piece of writing that presents an argument or a point of view. A composition, on the other hand, is a broader term that can refer to any piece of writing, including essays, research papers, and reports.
Creative Writing: In creative writing, the term “composition” is often used to refer to a piece of writing that is more artistic and expressive in nature. An essay, on the other hand, is typically more structured and focused on presenting an argument or a point of view.
Professional Writing: In professional writing, the term “composition” is often used to refer to a piece of writing that is more formal and technical in nature. An essay, on the other hand, is typically more informal and focused on presenting ideas or opinions.

In each of these contexts, the choice between essay and composition can depend on the specific requirements of the assignment or the preferences of the writer. It’s important to understand the nuances of each term and how they are used in different contexts in order to choose the most appropriate one for your writing.

Exceptions To The Rules

While essay and composition are often used interchangeably, there are some exceptions to the rules that should be noted. Here are some situations where the rules for using essay and composition might not apply:

1. Academic Writing

In academic writing, the term “essay” is typically used to refer to a shorter piece of writing that is assigned as homework or as part of an exam. However, in some cases, a longer piece of academic writing may be referred to as a composition. For example, a thesis or dissertation may be referred to as a composition.

2. Creative Writing

In creative writing, the term “composition” is often used to refer to a longer piece of writing that is more structured and formal than an essay. For example, a novel or a screenplay may be referred to as a composition. In this context, “essay” is typically used to refer to a shorter piece of writing, such as a personal essay or a memoir.

3. Regional Differences

There may be regional differences in the way that the terms “essay” and “composition” are used. For example, in some parts of the world, “essay” may be the preferred term for all types of writing, while in other parts of the world, “composition” may be used more frequently.

4. Personal Preference

Ultimately, the choice to use “essay” or “composition” may come down to personal preference. Some writers may prefer the more formal connotations of “composition,” while others may prefer the more casual connotations of “essay.”

Regardless of the context in which they are used, both essay and composition refer to a piece of writing that expresses the author’s thoughts and opinions on a particular topic. By understanding the exceptions to the rules, writers can choose the term that best fits their intended meaning and audience.

Practice Exercises

Now that we have a better understanding of the difference between an essay and a composition, it’s time to put that knowledge to the test. Here are some practice exercises to help you improve your understanding and use of these terms in sentences:

Exercise 1: Fill In The Blank

Fill in the blank with either “essay” or “composition” to complete the sentence correctly:

She spent all night writing her __________.
He received an A on his __________.
My teacher assigned a __________ on the Civil War.
The student’s __________ was well-written and thoroughly researched.
I need to write a __________ for my English class.

Answer Key:

composition

Exercise 2: Identify The Type

Read the following sentences and identify if the underlined word is an “essay” or a “composition”:

She wrote a five-paragraph __________ on the importance of recycling.
His __________ on the effects of climate change was over 10 pages long.
The teacher assigned a __________ on the differences between American and British English.
He spent hours composing a __________ about his family’s immigration story.
She submitted her __________ to the school newspaper for publication.

By practicing these exercises, you can improve your understanding and usage of “essay” and “composition.” Keep in mind that while they may be used interchangeably in some contexts, there are distinct differences between the two terms that should be understood in order to communicate effectively.

After examining the differences between essays and compositions, it is clear that the two terms are often used interchangeably but have distinct differences. Essays are typically more formal and structured, while compositions can be more creative and free-flowing. Additionally, essays often require research and citations, while compositions do not necessarily require them.

It is important for writers to understand the nuances between these two terms in order to effectively communicate their ideas and meet the expectations of their audience. By utilizing proper grammar and language use, writers can enhance the clarity and impact of their writing.

Key Takeaways:

Essays and compositions are two distinct forms of writing.
Essays are more formal and structured, while compositions can be more creative and free-flowing.
Essays often require research and citations, while compositions do not necessarily require them.
Understanding the differences between these terms can help writers effectively communicate their ideas and meet the expectations of their audience.

As with any skill, the ability to write effectively requires ongoing learning and practice. By continuing to study grammar and language use, writers can improve their writing and better connect with their readers.

How to Write a Literature Review | Guide, Examples, & Templates

Published on January 2, 2023 by Shona McCombes . Revised on September 11, 2023.

What is a literature review? A literature review is a survey of scholarly sources on a specific topic. It provides an overview of current knowledge, allowing you to identify relevant theories, methods, and gaps in the existing research that you can later apply to your paper, thesis, or dissertation topic .

There are five key steps to writing a literature review:

Search for relevant literature
Evaluate sources
Identify themes, debates, and gaps
Outline the structure
Write your literature review

A good literature review doesn’t just summarize sources—it analyzes, synthesizes , and critically evaluates to give a clear picture of the state of knowledge on the subject.

What is the purpose of a literature review, examples of literature reviews, step 1 – search for relevant literature, step 2 – evaluate and select sources, step 3 – identify themes, debates, and gaps, step 4 – outline your literature review’s structure, step 5 – write your literature review, free lecture slides, other interesting articles, frequently asked questions, introduction.

Quick Run-through
Step 1 & 2

When you write a thesis , dissertation , or research paper , you will likely have to conduct a literature review to situate your research within existing knowledge. The literature review gives you a chance to:

Demonstrate your familiarity with the topic and its scholarly context
Develop a theoretical framework and methodology for your research
Position your work in relation to other researchers and theorists
Show how your research addresses a gap or contributes to a debate
Evaluate the current state of research and demonstrate your knowledge of the scholarly debates around your topic.

Writing literature reviews is a particularly important skill if you want to apply for graduate school or pursue a career in research. We’ve written a step-by-step guide that you can follow below.

Prevent plagiarism. Run a free check.

Writing literature reviews can be quite challenging! A good starting point could be to look at some examples, depending on what kind of literature review you’d like to write.

Example literature review #1: “Why Do People Migrate? A Review of the Theoretical Literature” ( Theoretical literature review about the development of economic migration theory from the 1950s to today.)
Example literature review #2: “Literature review as a research methodology: An overview and guidelines” ( Methodological literature review about interdisciplinary knowledge acquisition and production.)
Example literature review #3: “The Use of Technology in English Language Learning: A Literature Review” ( Thematic literature review about the effects of technology on language acquisition.)
Example literature review #4: “Learners’ Listening Comprehension Difficulties in English Language Learning: A Literature Review” ( Chronological literature review about how the concept of listening skills has changed over time.)

You can also check out our templates with literature review examples and sample outlines at the links below.

Before you begin searching for literature, you need a clearly defined topic .

If you are writing the literature review section of a dissertation or research paper, you will search for literature related to your research problem and questions .

Make a list of keywords

Start by creating a list of keywords related to your research question. Include each of the key concepts or variables you’re interested in, and list any synonyms and related terms. You can add to this list as you discover new keywords in the process of your literature search.

Social media, Facebook, Instagram, Twitter, Snapchat, TikTok
Body image, self-perception, self-esteem, mental health
Generation Z, teenagers, adolescents, youth

Search for relevant sources

Use your keywords to begin searching for sources. Some useful databases to search for journals and articles include:

Your university’s library catalogue
Google Scholar
Project Muse (humanities and social sciences)
Medline (life sciences and biomedicine)
EconLit (economics)
Inspec (physics, engineering and computer science)

You can also use boolean operators to help narrow down your search.

Make sure to read the abstract to find out whether an article is relevant to your question. When you find a useful book or article, you can check the bibliography to find other relevant sources.

You likely won’t be able to read absolutely everything that has been written on your topic, so it will be necessary to evaluate which sources are most relevant to your research question.

For each publication, ask yourself:

What question or problem is the author addressing?
What are the key concepts and how are they defined?
What are the key theories, models, and methods?
Does the research use established frameworks or take an innovative approach?
What are the results and conclusions of the study?
How does the publication relate to other literature in the field? Does it confirm, add to, or challenge established knowledge?
What are the strengths and weaknesses of the research?

Make sure the sources you use are credible , and make sure you read any landmark studies and major theories in your field of research.

You can use our template to summarize and evaluate sources you’re thinking about using. Click on either button below to download.

Take notes and cite your sources

As you read, you should also begin the writing process. Take notes that you can later incorporate into the text of your literature review.

It is important to keep track of your sources with citations to avoid plagiarism . It can be helpful to make an annotated bibliography , where you compile full citation information and write a paragraph of summary and analysis for each source. This helps you remember what you read and saves time later in the process.

To begin organizing your literature review’s argument and structure, be sure you understand the connections and relationships between the sources you’ve read. Based on your reading and notes, you can look for:

Trends and patterns (in theory, method or results): do certain approaches become more or less popular over time?
Themes: what questions or concepts recur across the literature?
Debates, conflicts and contradictions: where do sources disagree?
Pivotal publications: are there any influential theories or studies that changed the direction of the field?
Gaps: what is missing from the literature? Are there weaknesses that need to be addressed?

This step will help you work out the structure of your literature review and (if applicable) show how your own research will contribute to existing knowledge.

Most research has focused on young women.
There is an increasing interest in the visual aspects of social media.
But there is still a lack of robust research on highly visual platforms like Instagram and Snapchat—this is a gap that you could address in your own research.

There are various approaches to organizing the body of a literature review. Depending on the length of your literature review, you can combine several of these strategies (for example, your overall structure might be thematic, but each theme is discussed chronologically).

Chronological

The simplest approach is to trace the development of the topic over time. However, if you choose this strategy, be careful to avoid simply listing and summarizing sources in order.

Try to analyze patterns, turning points and key debates that have shaped the direction of the field. Give your interpretation of how and why certain developments occurred.

If you have found some recurring central themes, you can organize your literature review into subsections that address different aspects of the topic.

For example, if you are reviewing literature about inequalities in migrant health outcomes, key themes might include healthcare policy, language barriers, cultural attitudes, legal status, and economic access.

Methodological

If you draw your sources from different disciplines or fields that use a variety of research methods , you might want to compare the results and conclusions that emerge from different approaches. For example:

Look at what results have emerged in qualitative versus quantitative research
Discuss how the topic has been approached by empirical versus theoretical scholarship
Divide the literature into sociological, historical, and cultural sources

Theoretical

A literature review is often the foundation for a theoretical framework . You can use it to discuss various theories, models, and definitions of key concepts.

You might argue for the relevance of a specific theoretical approach, or combine various theoretical concepts to create a framework for your research.

Like any other academic text , your literature review should have an introduction , a main body, and a conclusion . What you include in each depends on the objective of your literature review.

The introduction should clearly establish the focus and purpose of the literature review.

Depending on the length of your literature review, you might want to divide the body into subsections. You can use a subheading for each theme, time period, or methodological approach.

As you write, you can follow these tips:

Summarize and synthesize: give an overview of the main points of each source and combine them into a coherent whole
Analyze and interpret: don’t just paraphrase other researchers — add your own interpretations where possible, discussing the significance of findings in relation to the literature as a whole
Critically evaluate: mention the strengths and weaknesses of your sources
Write in well-structured paragraphs: use transition words and topic sentences to draw connections, comparisons and contrasts

In the conclusion, you should summarize the key findings you have taken from the literature and emphasize their significance.

A literature review is a survey of scholarly sources (such as books, journal articles, and theses) related to a specific topic or research question .

It is often written as part of a thesis, dissertation , or research paper , in order to situate your work in relation to existing knowledge.

There are several reasons to conduct a literature review at the beginning of a research project:

To familiarize yourself with the current state of knowledge on your topic
To ensure that you’re not just repeating what others have already done
To identify gaps in knowledge and unresolved problems that your research can address
To develop your theoretical framework and methodology
To provide an overview of the key findings and debates on the topic

Writing the literature review shows your reader how your work relates to existing research and what new insights it will contribute.

The literature review usually comes near the beginning of your thesis or dissertation . After the introduction , it grounds your research in a scholarly field and leads directly to your theoretical framework or methodology .

A literature review is a survey of credible sources on a topic, often used in dissertations , theses, and research papers . Literature reviews give an overview of knowledge on a subject, helping you identify relevant theories and methods, as well as gaps in existing research. Literature reviews are set up similarly to other academic texts , with an introduction , a main body, and a conclusion .

An annotated bibliography is a list of source references that has a short description (called an annotation ) for each of the sources. It is often assigned as part of the research process for a paper .

Recent advancements in artificial intelligence (AI) have led to an increased use of large language models (LLMs) for language assessment tasks such as automated essay scoring (AES), automated listening tests, and automated oral proficiency assessments. The application of LLMs for AES in the context of non-native Japanese, however, remains limited. This study explores the potential of LLM-based AES by comparing the efficiency of different models, i.e. two conventional machine training technology-based methods (Jess and JWriter), two LLMs (GPT and BERT), and one Japanese local LLM (Open-Calm large model). To conduct the evaluation, a dataset consisting of 1400 story-writing scripts authored by learners with 12 different first languages was used. Statistical analysis revealed that GPT-4 outperforms Jess and JWriter, BERT, and the Japanese language-specific trained Open-Calm large model in terms of annotation accuracy and predicting learning levels. Furthermore, by comparing 18 different models that utilize various prompts, the study emphasized the significance of prompts in achieving accurate and reliable evaluations using LLMs.

Conventional machine learning technology in aes.

AES has experienced significant growth with the advancement of machine learning technologies in recent decades. In the earlier stages of AES development, conventional machine learning-based approaches were commonly used. These approaches involved the following procedures: a) feeding the machine with a dataset. In this step, a dataset of essays is provided to the machine learning system. The dataset serves as the basis for training the model and establishing patterns and correlations between linguistic features and human ratings. b) the machine learning model is trained using linguistic features that best represent human ratings and can effectively discriminate learners’ writing proficiency. These features include lexical richness (Lu, 2012 ; Kyle and Crossley, 2015 ; Kyle et al. 2021 ), syntactic complexity (Lu, 2010 ; Liu, 2008 ), text cohesion (Crossley and McNamara, 2016 ), and among others. Conventional machine learning approaches in AES require human intervention, such as manual correction and annotation of essays. This human involvement was necessary to create a labeled dataset for training the model. Several AES systems have been developed using conventional machine learning technologies. These include the Intelligent Essay Assessor (Landauer et al. 2003 ), the e-rater engine by Educational Testing Service (Attali and Burstein, 2006 ; Burstein, 2003 ), MyAccess with the InterlliMetric scoring engine by Vantage Learning (Elliot, 2003 ), and the Bayesian Essay Test Scoring system (Rudner and Liang, 2002 ). These systems have played a significant role in automating the essay scoring process and providing quick and consistent feedback to learners. However, as touched upon earlier, conventional machine learning approaches rely on predetermined linguistic features and often require manual intervention, making them less flexible and potentially limiting their generalizability to different contexts.

In the context of the Japanese language, conventional machine learning-incorporated AES tools include Jess (Ishioka and Kameda, 2006 ) and JWriter (Lee and Hasebe, 2017 ). Jess assesses essays by deducting points from the perfect score, utilizing the Mainichi Daily News newspaper as a database. The evaluation criteria employed by Jess encompass various aspects, such as rhetorical elements (e.g., reading comprehension, vocabulary diversity, percentage of complex words, and percentage of passive sentences), organizational structures (e.g., forward and reverse connection structures), and content analysis (e.g., latent semantic indexing). JWriter employs linear regression analysis to assign weights to various measurement indices, such as average sentence length and total number of characters. These weights are then combined to derive the overall score. A pilot study involving the Jess model was conducted on 1320 essays at different proficiency levels, including primary, intermediate, and advanced. However, the results indicated that the Jess model failed to significantly distinguish between these essay levels. Out of the 16 measures used, four measures, namely median sentence length, median clause length, median number of phrases, and maximum number of phrases, did not show statistically significant differences between the levels. Additionally, two measures exhibited between-level differences but lacked linear progression: the number of attributives declined words and the Kanji/kana ratio. On the other hand, the remaining measures, including maximum sentence length, maximum clause length, number of attributive conjugated words, maximum number of consecutive infinitive forms, maximum number of conjunctive-particle clauses, k characteristic value, percentage of big words, and percentage of passive sentences, demonstrated statistically significant between-level differences and displayed linear progression.

Both Jess and JWriter exhibit notable limitations, including the manual selection of feature parameters and weights, which can introduce biases into the scoring process. The reliance on human annotators to label non-native language essays also introduces potential noise and variability in the scoring. Furthermore, an important concern is the possibility of system manipulation and cheating by learners who are aware of the regression equation utilized by the models (Hirao et al. 2020 ). These limitations emphasize the need for further advancements in AES systems to address these challenges.

Deep learning technology in AES

Deep learning has emerged as one of the approaches for improving the accuracy and effectiveness of AES. Deep learning-based AES methods utilize artificial neural networks that mimic the human brain’s functioning through layered algorithms and computational units. Unlike conventional machine learning, deep learning autonomously learns from the environment and past errors without human intervention. This enables deep learning models to establish nonlinear correlations, resulting in higher accuracy. Recent advancements in deep learning have led to the development of transformers, which are particularly effective in learning text representations. Noteworthy examples include bidirectional encoder representations from transformers (BERT) (Devlin et al. 2019 ) and the generative pretrained transformer (GPT) (OpenAI).

BERT is a linguistic representation model that utilizes a transformer architecture and is trained on two tasks: masked linguistic modeling and next-sentence prediction (Hirao et al. 2020 ; Vaswani et al. 2017 ). In the context of AES, BERT follows specific procedures, as illustrated in Fig. 1 : (a) the tokenized prompts and essays are taken as input; (b) special tokens, such as [CLS] and [SEP], are added to mark the beginning and separation of prompts and essays; (c) the transformer encoder processes the prompt and essay sequences, resulting in hidden layer sequences; (d) the hidden layers corresponding to the [CLS] tokens (T[CLS]) represent distributed representations of the prompts and essays; and (e) a multilayer perceptron uses these distributed representations as input to obtain the final score (Hirao et al. 2020 ).

AES system with BERT (Hirao et al. 2020 ).

The training of BERT using a substantial amount of sentence data through the Masked Language Model (MLM) allows it to capture contextual information within the hidden layers. Consequently, BERT is expected to be capable of identifying artificial essays as invalid and assigning them lower scores (Mizumoto and Eguchi, 2023 ). In the context of AES for nonnative Japanese learners, Hirao et al. ( 2020 ) combined the long short-term memory (LSTM) model proposed by Hochreiter and Schmidhuber ( 1997 ) with BERT to develop a tailored automated Essay Scoring System. The findings of their study revealed that the BERT model outperformed both the conventional machine learning approach utilizing character-type features such as “kanji” and “hiragana”, as well as the standalone LSTM model. Takeuchi et al. ( 2021 ) presented an approach to Japanese AES that eliminates the requirement for pre-scored essays by relying solely on reference texts or a model answer for the essay task. They investigated multiple similarity evaluation methods, including frequency of morphemes, idf values calculated on Wikipedia, LSI, LDA, word-embedding vectors, and document vectors produced by BERT. The experimental findings revealed that the method utilizing the frequency of morphemes with idf values exhibited the strongest correlation with human-annotated scores across different essay tasks. The utilization of BERT in AES encounters several limitations. Firstly, essays often exceed the model’s maximum length limit. Second, only score labels are available for training, which restricts access to additional information.

Mizumoto and Eguchi ( 2023 ) were pioneers in employing the GPT model for AES in non-native English writing. Their study focused on evaluating the accuracy and reliability of AES using the GPT-3 text-davinci-003 model, analyzing a dataset of 12,100 essays from the corpus of nonnative written English (TOEFL11). The findings indicated that AES utilizing the GPT-3 model exhibited a certain degree of accuracy and reliability. They suggest that GPT-3-based AES systems hold the potential to provide support for human ratings. However, applying GPT model to AES presents a unique natural language processing (NLP) task that involves considerations such as nonnative language proficiency, the influence of the learner’s first language on the output in the target language, and identifying linguistic features that best indicate writing quality in a specific language. These linguistic features may differ morphologically or syntactically from those present in the learners’ first language, as observed in (1)–(3).

我-送了-他-一本-书

Wǒ-sòngle-tā-yī běn-shū

1 sg .-give. past- him-one .cl- book

“I gave him a book.”

Agglutinative

彼-に-本-を-あげ-まし-た

Kare-ni-hon-o-age-mashi-ta

3 sg .- dat -hon- acc- give.honorification. past

Inflectional

Additionally, the morphological agglutination and subject-object-verb (SOV) order in Japanese, along with its idiomatic expressions, pose additional challenges for applying language models in AES tasks (4).

足-が棒-になり-ました

Ashi-ga bo-ni nar-mashita

leg- nom stick- dat become- past

“My leg became like a stick (I am extremely tired).”

The example sentence provided demonstrates the morpho-syntactic structure of Japanese and the presence of an idiomatic expression. In this sentence, the verb “なる” (naru), meaning “to become”, appears at the end of the sentence. The verb stem “なり” (nari) is attached with morphemes indicating honorification (“ます” - mashu) and tense (“た” - ta), showcasing agglutination. While the sentence can be literally translated as “my leg became like a stick”, it carries an idiomatic interpretation that implies “I am extremely tired”.

To overcome this issue, CyberAgent Inc. ( 2023 ) has developed the Open-Calm series of language models specifically designed for Japanese. Open-Calm consists of pre-trained models available in various sizes, such as Small, Medium, Large, and 7b. Figure 2 depicts the fundamental structure of the Open-Calm model. A key feature of this architecture is the incorporation of the Lora Adapter and GPT-NeoX frameworks, which can enhance its language processing capabilities.

GPT-NeoX Model Architecture (Okgetheng and Takeuchi 2024 ).

In a recent study conducted by Okgetheng and Takeuchi ( 2024 ), they assessed the efficacy of Open-Calm language models in grading Japanese essays. The research utilized a dataset of approximately 300 essays, which were annotated by native Japanese educators. The findings of the study demonstrate the considerable potential of Open-Calm language models in automated Japanese essay scoring. Specifically, among the Open-Calm family, the Open-Calm Large model (referred to as OCLL) exhibited the highest performance. However, it is important to note that, as of the current date, the Open-Calm Large model does not offer public access to its server. Consequently, users are required to independently deploy and operate the environment for OCLL. In order to utilize OCLL, users must have a PC equipped with an NVIDIA GeForce RTX 3060 (8 or 12 GB VRAM).

In summary, while the potential of LLMs in automated scoring of nonnative Japanese essays has been demonstrated in two studies—BERT-driven AES (Hirao et al. 2020 ) and OCLL-based AES (Okgetheng and Takeuchi, 2024 )—the number of research efforts in this area remains limited.

Another significant challenge in applying LLMs to AES lies in prompt engineering and ensuring its reliability and effectiveness (Brown et al. 2020 ; Rae et al. 2021 ; Zhang et al. 2021 ). Various prompting strategies have been proposed, such as the zero-shot chain of thought (CoT) approach (Kojima et al. 2022 ), which involves manually crafting diverse and effective examples. However, manual efforts can lead to mistakes. To address this, Zhang et al. ( 2021 ) introduced an automatic CoT prompting method called Auto-CoT, which demonstrates matching or superior performance compared to the CoT paradigm. Another prompt framework is trees of thoughts, enabling a model to self-evaluate its progress at intermediate stages of problem-solving through deliberate reasoning (Yao et al. 2023 ).

Beyond linguistic studies, there has been a noticeable increase in the number of foreign workers in Japan and Japanese learners worldwide (Ministry of Health, Labor, and Welfare of Japan, 2022 ; Japan Foundation, 2021 ). However, existing assessment methods, such as the Japanese Language Proficiency Test (JLPT), J-CAT, and TTBJ Footnote 1 , primarily focus on reading, listening, vocabulary, and grammar skills, neglecting the evaluation of writing proficiency. As the number of workers and language learners continues to grow, there is a rising demand for an efficient AES system that can reduce costs and time for raters and be utilized for employment, examinations, and self-study purposes.

This study aims to explore the potential of LLM-based AES by comparing the effectiveness of five models: two LLMs (GPT Footnote 2 and BERT), one Japanese local LLM (OCLL), and two conventional machine learning-based methods (linguistic feature-based scoring tools - Jess and JWriter).

The research questions addressed in this study are as follows:

To what extent do the LLM-driven AES and linguistic feature-based AES, when used as automated tools to support human rating, accurately reflect test takers’ actual performance?

What influence does the prompt have on the accuracy and performance of LLM-based AES methods?

The subsequent sections of the manuscript cover the methodology, including the assessment measures for nonnative Japanese writing proficiency, criteria for prompts, and the dataset. The evaluation section focuses on the analysis of annotations and rating scores generated by LLM-driven and linguistic feature-based AES methods.

Methodology

The dataset utilized in this study was obtained from the International Corpus of Japanese as a Second Language (I-JAS) Footnote 3 . This corpus consisted of 1000 participants who represented 12 different first languages. For the study, the participants were given a story-writing task on a personal computer. They were required to write two stories based on the 4-panel illustrations titled “Picnic” and “The key” (see Appendix A). Background information for the participants was provided by the corpus, including their Japanese language proficiency levels assessed through two online tests: J-CAT and SPOT. These tests evaluated their reading, listening, vocabulary, and grammar abilities. The learners’ proficiency levels were categorized into six levels aligned with the Common European Framework of Reference for Languages (CEFR) and the Reference Framework for Japanese Language Education (RFJLE): A1, A2, B1, B2, C1, and C2. According to Lee et al. ( 2015 ), there is a high level of agreement (r = 0.86) between the J-CAT and SPOT assessments, indicating that the proficiency certifications provided by J-CAT are consistent with those of SPOT. However, it is important to note that the scores of J-CAT and SPOT do not have a one-to-one correspondence. In this study, the J-CAT scores were used as a benchmark to differentiate learners of different proficiency levels. A total of 1400 essays were utilized, representing the beginner (aligned with A1), A2, B1, B2, C1, and C2 levels based on the J-CAT scores. Table 1 provides information about the learners’ proficiency levels and their corresponding J-CAT and SPOT scores.

A dataset comprising a total of 1400 essays from the story writing tasks was collected. Among these, 714 essays were utilized to evaluate the reliability of the LLM-based AES method, while the remaining 686 essays were designated as development data to assess the LLM-based AES’s capability to distinguish participants with varying proficiency levels. The GPT 4 API was used in this study. A detailed explanation of the prompt-assessment criteria is provided in Section Prompt . All essays were sent to the model for measurement and scoring.

Measures of writing proficiency for nonnative Japanese

Japanese exhibits a morphologically agglutinative structure where morphemes are attached to the word stem to convey grammatical functions such as tense, aspect, voice, and honorifics, e.g. (5).

食べ-させ-られ-まし-た-か

tabe-sase-rare-mashi-ta-ka

[eat (stem)-causative-passive voice-honorification-tense. past-question marker]

Japanese employs nine case particles to indicate grammatical functions: the nominative case particle が (ga), the accusative case particle を (o), the genitive case particle の (no), the dative case particle に (ni), the locative/instrumental case particle で (de), the ablative case particle から (kara), the directional case particle へ (e), and the comitative case particle と (to). The agglutinative nature of the language, combined with the case particle system, provides an efficient means of distinguishing between active and passive voice, either through morphemes or case particles, e.g. 食べる taberu “eat concusive . ” (active voice); 食べられる taberareru “eat concusive . ” (passive voice). In the active voice, “パンを食べる” (pan o taberu) translates to “to eat bread”. On the other hand, in the passive voice, it becomes “パンが食べられた” (pan ga taberareta), which means “(the) bread was eaten”. Additionally, it is important to note that different conjugations of the same lemma are considered as one type in order to ensure a comprehensive assessment of the language features. For example, e.g., 食べる taberu “eat concusive . ”; 食べている tabeteiru “eat progress .”; 食べた tabeta “eat past . ” as one type.

To incorporate these features, previous research (Suzuki, 1999 ; Watanabe et al. 1988 ; Ishioka, 2001 ; Ishioka and Kameda, 2006 ; Hirao et al. 2020 ) has identified complexity, fluency, and accuracy as crucial factors for evaluating writing quality. These criteria are assessed through various aspects, including lexical richness (lexical density, diversity, and sophistication), syntactic complexity, and cohesion (Kyle et al. 2021 ; Mizumoto and Eguchi, 2023 ; Ure, 1971 ; Halliday, 1985 ; Barkaoui and Hadidi, 2020 ; Zenker and Kyle, 2021 ; Kim et al. 2018 ; Lu, 2017 ; Ortega, 2015 ). Therefore, this study proposes five scoring categories: lexical richness, syntactic complexity, cohesion, content elaboration, and grammatical accuracy. A total of 16 measures were employed to capture these categories. The calculation process and specific details of these measures can be found in Table 2 .

T-unit, first introduced by Hunt ( 1966 ), is a measure used for evaluating speech and composition. It serves as an indicator of syntactic development and represents the shortest units into which a piece of discourse can be divided without leaving any sentence fragments. In the context of Japanese language assessment, Sakoda and Hosoi ( 2020 ) utilized T-unit as the basic unit to assess the accuracy and complexity of Japanese learners’ speaking and storytelling. The calculation of T-units in Japanese follows the following principles:

A single main clause constitutes 1 T-unit, regardless of the presence or absence of dependent clauses, e.g. (6).

ケンとマリはピクニックに行きました (main clause): 1 T-unit.

If a sentence contains a main clause along with subclauses, each subclause is considered part of the same T-unit, e.g. (7).

天気が良かったので (subclause)、ケンとマリはピクニックに行きました (main clause): 1 T-unit.

In the case of coordinate clauses, where multiple clauses are connected, each coordinated clause is counted separately. Thus, a sentence with coordinate clauses may have 2 T-units or more, e.g. (8).

ケンは地図で場所を探して (coordinate clause)、マリはサンドイッチを作りました (coordinate clause): 2 T-units.

Lexical diversity refers to the range of words used within a text (Engber, 1995 ; Kyle et al. 2021 ) and is considered a useful measure of the breadth of vocabulary in L n production (Jarvis, 2013a , 2013b ).

The type/token ratio (TTR) is widely recognized as a straightforward measure for calculating lexical diversity and has been employed in numerous studies. These studies have demonstrated a strong correlation between TTR and other methods of measuring lexical diversity (e.g., Bentz et al. 2016 ; Čech and Miroslav, 2018 ; Çöltekin and Taraka, 2018 ). TTR is computed by considering both the number of unique words (types) and the total number of words (tokens) in a given text. Given that the length of learners’ writing texts can vary, this study employs the moving average type-token ratio (MATTR) to mitigate the influence of text length. MATTR is calculated using a 50-word moving window. Initially, a TTR is determined for words 1–50 in an essay, followed by words 2–51, 3–52, and so on until the end of the essay is reached (Díez-Ortega and Kyle, 2023 ). The final MATTR scores were obtained by averaging the TTR scores for all 50-word windows. The following formula was employed to derive MATTR:

${\rm{MATTR}}({\rm{W}})=\frac{{\sum }_{{\rm{i}}=1}^{{\rm{N}}-{\rm{W}}+1}{{\rm{F}}}_{{\rm{i}}}}{{\rm{W}}({\rm{N}}-{\rm{W}}+1)}$

Here, N refers to the number of tokens in the corpus. W is the randomly selected token size (W < N). ${F}_{i}$ is the number of types in each window. The ${\rm{MATTR}}({\rm{W}})$ is the mean of a series of type-token ratios (TTRs) based on the word form for all windows. It is expected that individuals with higher language proficiency will produce texts with greater lexical diversity, as indicated by higher MATTR scores.

Lexical density was captured by the ratio of the number of lexical words to the total number of words (Lu, 2012 ). Lexical sophistication refers to the utilization of advanced vocabulary, often evaluated through word frequency indices (Crossley et al. 2013 ; Haberman, 2008 ; Kyle and Crossley, 2015 ; Laufer and Nation, 1995 ; Lu, 2012 ; Read, 2000 ). In line of writing, lexical sophistication can be interpreted as vocabulary breadth, which entails the appropriate usage of vocabulary items across various lexicon-grammatical contexts and registers (Garner et al. 2019 ; Kim et al. 2018 ; Kyle et al. 2018 ). In Japanese specifically, words are considered lexically sophisticated if they are not included in the “Japanese Education Vocabulary List Ver 1.0”. Footnote 4 Consequently, lexical sophistication was calculated by determining the number of sophisticated word types relative to the total number of words per essay. Furthermore, it has been suggested that, in Japanese writing, sentences should ideally have a length of no more than 40 to 50 characters, as this promotes readability. Therefore, the median and maximum sentence length can be considered as useful indices for assessment (Ishioka and Kameda, 2006 ).

Syntactic complexity was assessed based on several measures, including the mean length of clauses, verb phrases per T-unit, clauses per T-unit, dependent clauses per T-unit, complex nominals per clause, adverbial clauses per clause, coordinate phrases per clause, and mean dependency distance (MDD). The MDD reflects the distance between the governor and dependent positions in a sentence. A larger dependency distance indicates a higher cognitive load and greater complexity in syntactic processing (Liu, 2008 ; Liu et al. 2017 ). The MDD has been established as an efficient metric for measuring syntactic complexity (Jiang, Quyang, and Liu, 2019 ; Li and Yan, 2021 ). To calculate the MDD, the position numbers of the governor and dependent are subtracted, assuming that words in a sentence are assigned in a linear order, such as W1 … Wi … Wn. In any dependency relationship between words Wa and Wb, Wa is the governor and Wb is the dependent. The MDD of the entire sentence was obtained by taking the absolute value of governor – dependent:

MDD = $\frac{1}{n}{\sum }_{i=1}^{n}|{\rm{D}}{{\rm{D}}}_{i}|$

In this formula, $n$ represents the number of words in the sentence, and ${DD}i$ is the dependency distance of the ${i}^{{th}}$ dependency relationship of a sentence. Building on this, the annotation of sentence ‘Mary-ga-John-ni-keshigomu-o-watashita was [Mary- top -John- dat -eraser- acc -give- past] ’. The sentence’s MDD would be 2. Table 3 provides the CSV file as a prompt for GPT 4.

Cohesion (semantic similarity) and content elaboration aim to capture the ideas presented in test taker’s essays. Cohesion was assessed using three measures: Synonym overlap/paragraph (topic), Synonym overlap/paragraph (keywords), and word2vec cosine similarity. Content elaboration and development were measured as the number of metadiscourse markers (type)/number of words. To capture content closely, this study proposed a novel-distance based representation, by encoding the cosine distance between the essay (by learner) and essay task’s (topic and keyword) i -vectors. The learner’s essay is decoded into a word sequence, and aligned to the essay task’ topic and keyword for log-likelihood measurement. The cosine distance reveals the content elaboration score in the leaners’ essay. The mathematical equation of cosine similarity between target-reference vectors is shown in (11), assuming there are i essays and ( L i , …. L n ) and ( N i , …. N n ) are the vectors representing the learner and task’s topic and keyword respectively. The content elaboration distance between L i and N i was calculated as follows:

$\cos \left(\theta \right)=\frac{{\rm{L}}\,\cdot\, {\rm{N}}}{\left|{\rm{L}}\right|{\rm{|N|}}}=\frac{\mathop{\sum }\nolimits_{i=1}^{n}{L}_{i}{N}_{i}}{\sqrt{\mathop{\sum }\nolimits_{i=1}^{n}{L}_{i}^{2}}\sqrt{\mathop{\sum }\nolimits_{i=1}^{n}{N}_{i}^{2}}}$

A high similarity value indicates a low difference between the two recognition outcomes, which in turn suggests a high level of proficiency in content elaboration.

To evaluate the effectiveness of the proposed measures in distinguishing different proficiency levels among nonnative Japanese speakers’ writing, we conducted a multi-faceted Rasch measurement analysis (Linacre, 1994 ). This approach applies measurement models to thoroughly analyze various factors that can influence test outcomes, including test takers’ proficiency, item difficulty, and rater severity, among others. The underlying principles and functionality of multi-faceted Rasch measurement are illustrated in (12).

$\log \left(\frac{{P}_{{nijk}}}{{P}_{{nij}(k-1)}}\right)={B}_{n}-{D}_{i}-{C}_{j}-{F}_{k}$

(12) defines the logarithmic transformation of the probability ratio ( P nijk /P nij(k-1) )) as a function of multiple parameters. Here, n represents the test taker, i denotes a writing proficiency measure, j corresponds to the human rater, and k represents the proficiency score. The parameter B n signifies the proficiency level of test taker n (where n ranges from 1 to N). D j represents the difficulty parameter of test item i (where i ranges from 1 to L), while C j represents the severity of rater j (where j ranges from 1 to J). Additionally, F k represents the step difficulty for a test taker to move from score ‘k-1’ to k . P nijk refers to the probability of rater j assigning score k to test taker n for test item i . P nij(k-1) represents the likelihood of test taker n being assigned score ‘k-1’ by rater j for test item i . Each facet within the test is treated as an independent parameter and estimated within the same reference framework. To evaluate the consistency of scores obtained through both human and computer analysis, we utilized the Infit mean-square statistic. This statistic is a chi-square measure divided by the degrees of freedom and is weighted with information. It demonstrates higher sensitivity to unexpected patterns in responses to items near a person’s proficiency level (Linacre, 2002 ). Fit statistics are assessed based on predefined thresholds for acceptable fit. For the Infit MNSQ, which has a mean of 1.00, different thresholds have been suggested. Some propose stricter thresholds ranging from 0.7 to 1.3 (Bond et al. 2021 ), while others suggest more lenient thresholds ranging from 0.5 to 1.5 (Eckes, 2009 ). In this study, we adopted the criterion of 0.70–1.30 for the Infit MNSQ.

Moving forward, we can now proceed to assess the effectiveness of the 16 proposed measures based on five criteria for accurately distinguishing various levels of writing proficiency among non-native Japanese speakers. To conduct this evaluation, we utilized the development dataset from the I-JAS corpus, as described in Section Dataset . Table 4 provides a measurement report that presents the performance details of the 14 metrics under consideration. The measure separation was found to be 4.02, indicating a clear differentiation among the measures. The reliability index for the measure separation was 0.891, suggesting consistency in the measurement. Similarly, the person separation reliability index was 0.802, indicating the accuracy of the assessment in distinguishing between individuals. All 16 measures demonstrated Infit mean squares within a reasonable range, ranging from 0.76 to 1.28. The Synonym overlap/paragraph (topic) measure exhibited a relatively high outfit mean square of 1.46, although the Infit mean square falls within an acceptable range. The standard error for the measures ranged from 0.13 to 0.28, indicating the precision of the estimates.

Table 5 further illustrated the weights assigned to different linguistic measures for score prediction, with higher weights indicating stronger correlations between those measures and higher scores. Specifically, the following measures exhibited higher weights compared to others: moving average type token ratio per essay has a weight of 0.0391. Mean dependency distance had a weight of 0.0388. Mean length of clause, calculated by dividing the number of words by the number of clauses, had a weight of 0.0374. Complex nominals per T-unit, calculated by dividing the number of complex nominals by the number of T-units, had a weight of 0.0379. Coordinate phrases rate, calculated by dividing the number of coordinate phrases by the number of clauses, had a weight of 0.0325. Grammatical error rate, representing the number of errors per essay, had a weight of 0.0322.

Criteria (output indicator)

The criteria used to evaluate the writing ability in this study were based on CEFR, which follows a six-point scale ranging from A1 to C2. To assess the quality of Japanese writing, the scoring criteria from Table 6 were utilized. These criteria were derived from the IELTS writing standards and served as assessment guidelines and prompts for the written output.

A prompt is a question or detailed instruction that is provided to the model to obtain a proper response. After several pilot experiments, we decided to provide the measures (Section Measures of writing proficiency for nonnative Japanese ) as the input prompt and use the criteria (Section Criteria (output indicator) ) as the output indicator. Regarding the prompt language, considering that the LLM was tasked with rating Japanese essays, would prompt in Japanese works better Footnote 5 ? We conducted experiments comparing the performance of GPT-4 using both English and Japanese prompts. Additionally, we utilized the Japanese local model OCLL with Japanese prompts. Multiple trials were conducted using the same sample. Regardless of the prompt language used, we consistently obtained the same grading results with GPT-4, which assigned a grade of B1 to the writing sample. This suggested that GPT-4 is reliable and capable of producing consistent ratings regardless of the prompt language. On the other hand, when we used Japanese prompts with the Japanese local model “OCLL”, we encountered inconsistent grading results. Out of 10 attempts with OCLL, only 6 yielded consistent grading results (B1), while the remaining 4 showed different outcomes, including A1 and B2 grades. These findings indicated that the language of the prompt was not the determining factor for reliable AES. Instead, the size of the training data and the model parameters played crucial roles in achieving consistent and reliable AES results for the language model.

The following is the utilized prompt, which details all measures and requires the LLM to score the essays using holistic and trait scores.

Please evaluate Japanese essays written by Japanese learners and assign a score to each essay on a six-point scale, ranging from A1, A2, B1, B2, C1 to C2. Additionally, please provide trait scores and display the calculation process for each trait score. The scoring should be based on the following criteria:

Moving average type-token ratio.

Number of lexical words (token) divided by the total number of words per essay.

Number of sophisticated word types divided by the total number of words per essay.

Mean length of clause.

Verb phrases per T-unit.

Clauses per T-unit.

Statistical analysis

The aim of this study is to investigate the potential use of LLM for nonnative Japanese AES. It seeks to compare the scoring outcomes obtained from feature-based AES tools, which rely on conventional machine learning technology (i.e. Jess, JWriter), with those generated by AI-driven AES tools utilizing deep learning technology (BERT, GPT, OCLL). To assess the reliability of a computer-assisted annotation tool, the study initially established human-human agreement as the benchmark measure. Subsequently, the performance of the LLM-based method was evaluated by comparing it to human-human agreement.

To assess annotation agreement, the study employed standard measures such as precision, recall, and F-score (Brants 2000 ; Lu 2010 ), along with the quadratically weighted kappa (QWK) to evaluate the consistency and agreement in the annotation process. Assume A and B represent human annotators. When comparing the annotations of the two annotators, the following results are obtained. The evaluation of precision, recall, and F-score metrics was illustrated in equations (13) to (15).

${\rm{Recall}}(A,B)=\frac{{\rm{Number}}\,{\rm{of}}\,{\rm{identical}}\,{\rm{nodes}}\,{\rm{in}}\,A\,{\rm{and}}\,B}{{\rm{Number}}\,{\rm{of}}\,{\rm{nodes}}\,{\rm{in}}\,A}$

${\rm{Precision}}(A,\,B)=\frac{{\rm{Number}}\,{\rm{of}}\,{\rm{identical}}\,{\rm{nodes}}\,{\rm{in}}\,A\,{\rm{and}}\,B}{{\rm{Number}}\,{\rm{of}}\,{\rm{nodes}}\,{\rm{in}}\,B}$

The F-score is the harmonic mean of recall and precision:

${\rm{F}}-{\rm{score}}=\frac{2* ({\rm{Precision}}* {\rm{Recall}})}{{\rm{Precision}}+{\rm{Recall}}}$

The highest possible value of an F-score is 1.0, indicating perfect precision and recall, and the lowest possible value is 0, if either precision or recall are zero.

In accordance with Taghipour and Ng ( 2016 ), the calculation of QWK involves two steps:

Step 1: Construct a weight matrix W as follows:

${W}_{{ij}}=\frac{{(i-j)}^{2}}{{(N-1)}^{2}}$

i represents the annotation made by the tool, while j represents the annotation made by a human rater. N denotes the total number of possible annotations. Matrix O is subsequently computed, where O_( i, j ) represents the count of data annotated by the tool ( i ) and the human annotator ( j ). On the other hand, E refers to the expected count matrix, which undergoes normalization to ensure that the sum of elements in E matches the sum of elements in O.

Step 2: With matrices O and E, the QWK is obtained as follows:

K = 1- $\frac{\sum i,j{W}_{i,j}\,{O}_{i,j}}{\sum i,j{W}_{i,j}\,{E}_{i,j}}$

The value of the quadratic weighted kappa increases as the level of agreement improves. Further, to assess the accuracy of LLM scoring, the proportional reductive mean square error (PRMSE) was employed. The PRMSE approach takes into account the variability observed in human ratings to estimate the rater error, which is then subtracted from the variance of the human labels. This calculation provides an overall measure of agreement between the automated scores and true scores (Haberman et al. 2015 ; Loukina et al. 2020 ; Taghipour and Ng, 2016 ). The computation of PRMSE involves the following steps:

Step 1: Calculate the mean squared errors (MSEs) for the scoring outcomes of the computer-assisted tool (MSE tool) and the human scoring outcomes (MSE human).

Step 2: Determine the PRMSE by comparing the MSE of the computer-assisted tool (MSE tool) with the MSE from human raters (MSE human), using the following formula:

${\rm{PRMSE}}=1-\frac{({\rm{MSE}}\,{\rm{tool}})\,}{({\rm{MSE}}\,{\rm{human}})\,}=1-\,\frac{{\sum }_{i}^{n}=1{({{\rm{y}}}_{i}-{\hat{{\rm{y}}}}_{{\rm{i}}})}^{2}}{{\sum }_{i}^{n}=1{({{\rm{y}}}_{i}-\hat{{\rm{y}}})}^{2}}$

In the numerator, ŷi represents the scoring outcome predicted by a specific LLM-driven AES system for a given sample. The term y i − ŷ i represents the difference between this predicted outcome and the mean value of all LLM-driven AES systems’ scoring outcomes. It quantifies the deviation of the specific LLM-driven AES system’s prediction from the average prediction of all LLM-driven AES systems. In the denominator, y i − ŷ represents the difference between the scoring outcome provided by a specific human rater for a given sample and the mean value of all human raters’ scoring outcomes. It measures the discrepancy between the specific human rater’s score and the average score given by all human raters. The PRMSE is then calculated by subtracting the ratio of the MSE tool to the MSE human from 1. PRMSE falls within the range of 0 to 1, with larger values indicating reduced errors in LLM’s scoring compared to those of human raters. In other words, a higher PRMSE implies that LLM’s scoring demonstrates greater accuracy in predicting the true scores (Loukina et al. 2020 ). The interpretation of kappa values, ranging from 0 to 1, is based on the work of Landis and Koch ( 1977 ). Specifically, the following categories are assigned to different ranges of kappa values: −1 indicates complete inconsistency, 0 indicates random agreement, 0.0 ~ 0.20 indicates extremely low level of agreement (slight), 0.21 ~ 0.40 indicates moderate level of agreement (fair), 0.41 ~ 0.60 indicates medium level of agreement (moderate), 0.61 ~ 0.80 indicates high level of agreement (substantial), 0.81 ~ 1 indicates almost perfect level of agreement. All statistical analyses were executed using Python script.

Results and discussion

Annotation reliability of the llm.

This section focuses on assessing the reliability of the LLM’s annotation and scoring capabilities. To evaluate the reliability, several tests were conducted simultaneously, aiming to achieve the following objectives:

Assess the LLM’s ability to differentiate between test takers with varying levels of oral proficiency.

Determine the level of agreement between the annotations and scoring performed by the LLM and those done by human raters.

The evaluation of the results encompassed several metrics, including: precision, recall, F-Score, quadratically-weighted kappa, proportional reduction of mean squared error, Pearson correlation, and multi-faceted Rasch measurement.

Inter-annotator agreement (human–human annotator agreement)

We started with an agreement test of the two human annotators. Two trained annotators were recruited to determine the writing task data measures. A total of 714 scripts, as the test data, was utilized. Each analysis lasted 300–360 min. Inter-annotator agreement was evaluated using the standard measures of precision, recall, and F-score and QWK. Table 7 presents the inter-annotator agreement for the various indicators. As shown, the inter-annotator agreement was fairly high, with F-scores ranging from 1.0 for sentence and word number to 0.666 for grammatical errors.

The findings from the QWK analysis provided further confirmation of the inter-annotator agreement. The QWK values covered a range from 0.950 ( p = 0.000) for sentence and word number to 0.695 for synonym overlap number (keyword) and grammatical errors ( p = 0.001).

Agreement of annotation outcomes between human and LLM

To evaluate the consistency between human annotators and LLM annotators (BERT, GPT, OCLL) across the indices, the same test was conducted. The results of the inter-annotator agreement (F-score) between LLM and human annotation are provided in Appendix B-D. The F-scores ranged from 0.706 for Grammatical error # for OCLL-human to a perfect 1.000 for GPT-human, for sentences, clauses, T-units, and words. These findings were further supported by the QWK analysis, which showed agreement levels ranging from 0.807 ( p = 0.001) for metadiscourse markers for OCLL-human to 0.962 for words ( p = 0.000) for GPT-human. The findings demonstrated that the LLM annotation achieved a significant level of accuracy in identifying measurement units and counts.

Reliability of LLM-driven AES’s scoring and discriminating proficiency levels

This section examines the reliability of the LLM-driven AES scoring through a comparison of the scoring outcomes produced by human raters and the LLM ( Reliability of LLM-driven AES scoring ). It also assesses the effectiveness of the LLM-based AES system in differentiating participants with varying proficiency levels ( Reliability of LLM-driven AES discriminating proficiency levels ).

Reliability of LLM-driven AES scoring

Table 8 summarizes the QWK coefficient analysis between the scores computed by the human raters and the GPT-4 for the individual essays from I-JAS Footnote 7 . As shown, the QWK of all measures ranged from k = 0.819 for lexical density (number of lexical words (tokens)/number of words per essay) to k = 0.644 for word2vec cosine similarity. Table 9 further presents the Pearson correlations between the 16 writing proficiency measures scored by human raters and GPT 4 for the individual essays. The correlations ranged from 0.672 for syntactic complexity to 0.734 for grammatical accuracy. The correlations between the writing proficiency scores assigned by human raters and the BERT-based AES system were found to range from 0.661 for syntactic complexity to 0.713 for grammatical accuracy. The correlations between the writing proficiency scores given by human raters and the OCLL-based AES system ranged from 0.654 for cohesion to 0.721 for grammatical accuracy. These findings indicated an alignment between the assessments made by human raters and both the BERT-based and OCLL-based AES systems in terms of various aspects of writing proficiency.

Reliability of LLM-driven AES discriminating proficiency levels

After validating the reliability of the LLM’s annotation and scoring, the subsequent objective was to evaluate its ability to distinguish between various proficiency levels. For this analysis, a dataset of 686 individual essays was utilized. Table 10 presents a sample of the results, summarizing the means, standard deviations, and the outcomes of the one-way ANOVAs based on the measures assessed by the GPT-4 model. A post hoc multiple comparison test, specifically the Bonferroni test, was conducted to identify any potential differences between pairs of levels.

As the results reveal, seven measures presented linear upward or downward progress across the three proficiency levels. These were marked in bold in Table 10 and comprise one measure of lexical richness, i.e. MATTR (lexical diversity); four measures of syntactic complexity, i.e. MDD (mean dependency distance), MLC (mean length of clause), CNT (complex nominals per T-unit), CPC (coordinate phrases rate); one cohesion measure, i.e. word2vec cosine similarity and GER (grammatical error rate). Regarding the ability of the sixteen measures to distinguish adjacent proficiency levels, the Bonferroni tests indicated that statistically significant differences exist between the primary level and the intermediate level for MLC and GER. One measure of lexical richness, namely LD, along with three measures of syntactic complexity (VPT, CT, DCT, ACC), two measures of cohesion (SOPT, SOPK), and one measure of content elaboration (IMM), exhibited statistically significant differences between proficiency levels. However, these differences did not demonstrate a linear progression between adjacent proficiency levels. No significant difference was observed in lexical sophistication between proficiency levels.

To summarize, our study aimed to evaluate the reliability and differentiation capabilities of the LLM-driven AES method. For the first objective, we assessed the LLM’s ability to differentiate between test takers with varying levels of oral proficiency using precision, recall, F-Score, and quadratically-weighted kappa. Regarding the second objective, we compared the scoring outcomes generated by human raters and the LLM to determine the level of agreement. We employed quadratically-weighted kappa and Pearson correlations to compare the 16 writing proficiency measures for the individual essays. The results confirmed the feasibility of using the LLM for annotation and scoring in AES for nonnative Japanese. As a result, Research Question 1 has been addressed.

Comparison of BERT-, GPT-, OCLL-based AES, and linguistic-feature-based computation methods

This section aims to compare the effectiveness of five AES methods for nonnative Japanese writing, i.e. LLM-driven approaches utilizing BERT, GPT, and OCLL, linguistic feature-based approaches using Jess and JWriter. The comparison was conducted by comparing the ratings obtained from each approach with human ratings. All ratings were derived from the dataset introduced in Dataset . To facilitate the comparison, the agreement between the automated methods and human ratings was assessed using QWK and PRMSE. The performance of each approach was summarized in Table 11 .

The QWK coefficient values indicate that LLMs (GPT, BERT, OCLL) and human rating outcomes demonstrated higher agreement compared to feature-based AES methods (Jess and JWriter) in assessing writing proficiency criteria, including lexical richness, syntactic complexity, content, and grammatical accuracy. Among the LLMs, the GPT-4 driven AES and human rating outcomes showed the highest agreement in all criteria, except for syntactic complexity. The PRMSE values suggest that the GPT-based method outperformed linguistic feature-based methods and other LLM-based approaches. Moreover, an interesting finding emerged during the study: the agreement coefficient between GPT-4 and human scoring was even higher than the agreement between different human raters themselves. This discovery highlights the advantage of GPT-based AES over human rating. Ratings involve a series of processes, including reading the learners’ writing, evaluating the content and language, and assigning scores. Within this chain of processes, various biases can be introduced, stemming from factors such as rater biases, test design, and rating scales. These biases can impact the consistency and objectivity of human ratings. GPT-based AES may benefit from its ability to apply consistent and objective evaluation criteria. By prompting the GPT model with detailed writing scoring rubrics and linguistic features, potential biases in human ratings can be mitigated. The model follows a predefined set of guidelines and does not possess the same subjective biases that human raters may exhibit. This standardization in the evaluation process contributes to the higher agreement observed between GPT-4 and human scoring. Section Prompt strategy of the study delves further into the role of prompts in the application of LLMs to AES. It explores how the choice and implementation of prompts can impact the performance and reliability of LLM-based AES methods. Furthermore, it is important to acknowledge the strengths of the local model, i.e. the Japanese local model OCLL, which excels in processing certain idiomatic expressions. Nevertheless, our analysis indicated that GPT-4 surpasses local models in AES. This superior performance can be attributed to the larger parameter size of GPT-4, estimated to be between 500 billion and 1 trillion, which exceeds the sizes of both BERT and the local model OCLL.

Prompt strategy

In the context of prompt strategy, Mizumoto and Eguchi ( 2023 ) conducted a study where they applied the GPT-3 model to automatically score English essays in the TOEFL test. They found that the accuracy of the GPT model alone was moderate to fair. However, when they incorporated linguistic measures such as cohesion, syntactic complexity, and lexical features alongside the GPT model, the accuracy significantly improved. This highlights the importance of prompt engineering and providing the model with specific instructions to enhance its performance. In this study, a similar approach was taken to optimize the performance of LLMs. GPT-4, which outperformed BERT and OCLL, was selected as the candidate model. Model 1 was used as the baseline, representing GPT-4 without any additional prompting. Model 2, on the other hand, involved GPT-4 prompted with 16 measures that included scoring criteria, efficient linguistic features for writing assessment, and detailed measurement units and calculation formulas. The remaining models (Models 3 to 18) utilized GPT-4 prompted with individual measures. The performance of these 18 different models was assessed using the output indicators described in Section Criteria (output indicator) . By comparing the performances of these models, the study aimed to understand the impact of prompt engineering on the accuracy and effectiveness of GPT-4 in AES tasks.

Based on the PRMSE scores presented in Fig. 4 , it was observed that Model 1, representing GPT-4 without any additional prompting, achieved a fair level of performance. However, Model 2, which utilized GPT-4 prompted with all measures, outperformed all other models in terms of PRMSE score, achieving a score of 0.681. These results indicate that the inclusion of specific measures and prompts significantly enhanced the performance of GPT-4 in AES. Among the measures, syntactic complexity was found to play a particularly significant role in improving the accuracy of GPT-4 in assessing writing quality. Following that, lexical diversity emerged as another important factor contributing to the model’s effectiveness. The study suggests that a well-prompted GPT-4 can serve as a valuable tool to support human assessors in evaluating writing quality. By utilizing GPT-4 as an automated scoring tool, the evaluation biases associated with human raters can be minimized. This has the potential to empower teachers by allowing them to focus on designing writing tasks and guiding writing strategies, while leveraging the capabilities of GPT-4 for efficient and reliable scoring.

PRMSE scores of the 18 AES models.

This study aimed to investigate two main research questions: the feasibility of utilizing LLMs for AES and the impact of prompt engineering on the application of LLMs in AES.

To address the first objective, the study compared the effectiveness of five different models: GPT, BERT, the Japanese local LLM (OCLL), and two conventional machine learning-based AES tools (Jess and JWriter). The PRMSE values indicated that the GPT-4-based method outperformed other LLMs (BERT, OCLL) and linguistic feature-based computational methods (Jess and JWriter) across various writing proficiency criteria. Furthermore, the agreement coefficient between GPT-4 and human scoring surpassed the agreement among human raters themselves, highlighting the potential of using the GPT-4 tool to enhance AES by reducing biases and subjectivity, saving time, labor, and cost, and providing valuable feedback for self-study. Regarding the second goal, the role of prompt design was investigated by comparing 18 models, including a baseline model, a model prompted with all measures, and 16 models prompted with one measure at a time. GPT-4, which outperformed BERT and OCLL, was selected as the candidate model. The PRMSE scores of the models showed that GPT-4 prompted with all measures achieved the best performance, surpassing the baseline and other models.

In conclusion, this study has demonstrated the potential of LLMs in supporting human rating in assessments. By incorporating automation, we can save time and resources while reducing biases and subjectivity inherent in human rating processes. Automated language assessments offer the advantage of accessibility, providing equal opportunities and economic feasibility for individuals who lack access to traditional assessment centers or necessary resources. LLM-based language assessments provide valuable feedback and support to learners, aiding in the enhancement of their language proficiency and the achievement of their goals. This personalized feedback can cater to individual learner needs, facilitating a more tailored and effective language-learning experience.

There are three important areas that merit further exploration. First, prompt engineering requires attention to ensure optimal performance of LLM-based AES across different language types. This study revealed that GPT-4, when prompted with all measures, outperformed models prompted with fewer measures. Therefore, investigating and refining prompt strategies can enhance the effectiveness of LLMs in automated language assessments. Second, it is crucial to explore the application of LLMs in second-language assessment and learning for oral proficiency, as well as their potential in under-resourced languages. Recent advancements in self-supervised machine learning techniques have significantly improved automatic speech recognition (ASR) systems, opening up new possibilities for creating reliable ASR systems, particularly for under-resourced languages with limited data. However, challenges persist in the field of ASR. First, ASR assumes correct word pronunciation for automatic pronunciation evaluation, which proves challenging for learners in the early stages of language acquisition due to diverse accents influenced by their native languages. Accurately segmenting short words becomes problematic in such cases. Second, developing precise audio-text transcriptions for languages with non-native accented speech poses a formidable task. Last, assessing oral proficiency levels involves capturing various linguistic features, including fluency, pronunciation, accuracy, and complexity, which are not easily captured by current NLP technology.

We tested a new ChatGPT-detector for teachers. It flagged an innocent student.

Five high school students helped our tech columnist test a ChatGPT detector coming from Turnitin to 2.1 million teachers. It missed enough to get someone in trouble.

High school senior Lucy Goetz got the highest possible grade on an original essay she wrote about socialism. So imagine her surprise when I told her that a new kind of educational software I’ve been testing claimed she got help from artificial intelligence.

A new AI-writing detector from Turnitin — whose software is already used by 2.1 million teachers to spot plagiarism — flagged the end of her essay as likely being generated by ChatGPT .

“Say what?” says Goetz, who swears she didn’t use the AI writing tool to cheat. “I’m glad I have good relationships with my teachers.”

After months of sounding the alarm about students using AI apps that can churn out essays and assignments, teachers are getting AI technology of their own. On April 4, Turnitin is activating the software I tested for some 10,700 secondary and higher-educational institutions, assigning “generated by AI” scores and sentence-by-sentence analysis to student work. It joins a handful of other free detectors already online. For many teachers I’ve been hearing from, AI detection offers a weapon to deter a 21st-century form of cheating.

But AI alone won’t solve the problem AI created. The flag on a portion of Goetz’s essay was an outlier, but shows detectors can sometimes get it wrong — with potentially disastrous consequences for students. Detectors are being introduced before they’ve been widely vetted, yet AI tech is moving so fast, any tool is likely already out of date.

It’s a pivotal moment for educators: Ignore AI and cheating could go rampant. Yet even Turnitin’s executives tell me that treating AI purely as the enemy of education makes about as much sense in the long run as trying to ban calculators.

Has tipping gone too far? Here’s a guide on when to tip.

Ahead of Turnitin’s launch this week, the company says 2 percent of customers have asked it not to display the AI writing score on student work. That includes a "significant majority” of universities in the United Kingdom, according to UCISA , a professional body for digital educators.

To see what’s at stake, I asked Turnitin for early access to its software. Five high school students, including Goetz, volunteered to help me test it by creating 16 samples of real, AI-fabricated and mixed-source essays to run past Turnitin’s detector.

The result? It got over half of them at least partly wrong. Turnitin accurately identified six of the 16 — but failed on three, including a flag on 8 percent of Goetz’s original essay. And I’d give it only partial credit on the remaining seven, where it was directionally correct but misidentified some portion of ChatGPT-generated or mixed-source writing.

Turnitin claims its detector is 98 percent accurate overall. And it says situations such as what happened with Goetz’s essay, known as a false positive, happen less than 1 percent of the time, according to its own tests.

Turnitin also says its scores should be treated as an indication, not an accusation . Still, will millions of teachers understand they should treat AI scores as anything other than fact? After my conversations with the company, it added a caution flag to its score that reads, “Percentage may not indicate cheating. Review required.”

“Our job is to create directionally correct information for the teacher to prompt a conversation,” Turnitin chief product officer Annie Chechitelli tells me. “I’m confident enough to put it out in the market, as long as we’re continuing to educate educators on how to use the data.” She says the company will keep adjusting its software based on feedback and new AI advancements.

The question is whether that will be enough. “The fact that the Turnitin system for flagging AI text doesn’t work all the time is concerning,” says Rebecca Dell, who teaches Goetz’s AP English class in Concord, Calif. “I’m not sure how schools will be able to definitively use the checker as ‘evidence’ of students using unoriginal work.”

Unlike accusations of plagiarism, AI cheating has no source document to reference as proof. “This leaves the door open for teacher bias to creep in,” says Dell.

For students, that makes the prospect of being accused of AI cheating especially scary. “There is no way to prove that you didn’t cheat unless your teacher knows your writing style, or trusts you as a student,” says Goetz.

Why detecting AI is so hard

Spotting AI writing sounds deceptively simple. When a colleague recently asked me if I could detect the difference between real and ChatGPT-generated emails, I didn’t perform very well.

Detecting AI writing with software involves statistics. And statistically speaking, the thing that makes AI distinct from humans is that it’s “extremely consistently average,” says Eric Wang, Turnitin’s vice president of AI.

Systems such as ChatGPT work like a sophisticated version of auto-complete, looking for the most probable word to write next. “That’s actually the reason why it reads so naturally: AI writing is the most probable subset of human writing,” he says.

Turnitin’s detector “identifies when writing is too consistently average,” Wang says.

The challenge is that sometimes a human writer may actually look consistently average.

On economics, math and lab reports, students tend to hew to set styles, meaning they’re more likely to be misidentified as AI writing, says Wang. That’s likely why Turnitin erroneously flagged Goetz’s essay, which veered into economics. (“My teachers have always been fairly impressed with my writing,” says Goetz.)

Wang says Turnitin worked to tune its systems to err on the side of requiring higher confidence before flagging a sentence as AI. I saw that develop in real time: I first tested Goetz’s essay in late January, and the software identified much more of it — about 50 percent — as being AI generated. Turnitin ran my samples through its system again in late March, and that time only flagged 8 percent of Goetz’s essay as AI-generated.

But tightening up the software’s tolerance came with a cost: Across the second test of my samples, Turnitin missed more actual AI writing. “We’re really emphasizing student safety,” says Chechitelli.

Say hello to your new tutor: It’s ChatGPT

Turnitin does perform better than other public AI detectors I tested. One introduced in February by OpenAI, the company that invented ChatGPT, got eight of our 16 test samples wrong. (Independent tests of other detectors have declared they “ fail spectacularly .”)

Turnitin’s detector faces other important technical limitations, too. In the six samples it got completely right, they were all clearly 100 percent student work or produced by ChatGPT. But when I tested it with essays from mixed AI and human sources, it often misidentified the individual sentences or missed the human part entirely. And it couldn’t spot the ChatGPT in papers we ran through Quillbot, a paraphrasing program that remixes sentences.

What’s more, Turnitin’s detector may already be behind the state of the AI art. My student helpers created samples with ChatGPT, but since they did the writing, the app has gotten a software update called GPT-4 with more creative and stylistic capabilities. Google also introduced a new AI bot called Bard . Wang says addressing them is on his road map.

Some AI experts say any detection efforts are at best setting up an arms race between cheaters and detectors. “I don’t think a detector is long-term reliable,” says Jim Fan, an AI scientist at Nvidia who used to work at OpenAI and Google.

“The AI will get better, and will write in ways more and more like humans. It is pretty safe to say that all of these little quirks of language models will be reduced over time,” he says.

Is detecting AI a good idea?

Given the potential — even at 1 percent — of being wrong, why release an AI detector into software that will touch so many students?

“Teachers want deterrence,” says Chechitelli. They’re extremely worried about AI and helping them see the scale of the actual problem will “bring down the temperature.”
