How to write a thesis statement, what is a thesis statement.

Almost all of us—even if we don’t do it consciously—look early in an essay for a one- or two-sentence condensation of the argument or analysis that is to follow. We refer to that condensation as a thesis statement.

Why Should Your Essay Contain a Thesis Statement?

• to test your ideas by distilling them into a sentence or two
• to better organize and develop your argument
• to provide your reader with a “guide” to your argument

In general, your thesis statement will accomplish these goals if you think of the thesis as the answer to the question your paper explores.

How Can You Write a Good Thesis Statement?

Here are some helpful hints to get you started. You can either scroll down or select a link to a specific topic.

How to Generate a Thesis Statement if the Topic is Assigned

Almost all assignments, no matter how complicated, can be reduced to a single question. Your first step, then, is to distill the assignment into a specific question. For example, if your assignment is, “Write a report to the local school board explaining the potential benefits of using computers in a fourth-grade class,” turn the request into a question like, “What are the potential benefits of using computers in a fourth-grade class?” After you’ve chosen the question your essay will answer, compose one or two complete sentences answering that question.

Q: “What are the potential benefits of using computers in a fourth-grade class?” A: “The potential benefits of using computers in a fourth-grade class are . . .”

A: “Using computers in a fourth-grade class promises to improve . . .”

The answer to the question is the thesis statement for the essay.

How to Generate a Thesis Statement if the Topic is not Assigned

Even if your assignment doesn’t ask a specific question, your thesis statement still needs to answer a question about the issue you’d like to explore. In this situation, your job is to figure out what question you’d like to write about.

A good thesis statement will usually include the following four attributes:

• take on a subject upon which reasonable people could disagree
• deal with a subject that can be adequately treated given the nature of the assignment
• express one main idea
• assert your conclusions about a subject

Let’s see how to generate a thesis statement for a social policy paper.

Brainstorm the topic . Let’s say that your class focuses upon the problems posed by changes in the dietary habits of Americans. You find that you are interested in the amount of sugar Americans consume.

You start out with a thesis statement like this:

Sugar consumption.

This fragment isn’t a thesis statement. Instead, it simply indicates a general subject. Furthermore, your reader doesn’t know what you want to say about sugar consumption.

Narrow the topic . Your readings about the topic, however, have led you to the conclusion that elementary school children are consuming far more sugar than is healthy.

You change your thesis to look like this:

Reducing sugar consumption by elementary school children.

This fragment not only announces your subject, but it focuses on one segment of the population: elementary school children. Furthermore, it raises a subject upon which reasonable people could disagree, because while most people might agree that children consume more sugar than they used to, not everyone would agree on what should be done or who should do it. You should note that this fragment is not a thesis statement because your reader doesn’t know your conclusions on the topic.

Take a position on the topic. After reflecting on the topic a little while longer, you decide that what you really want to say about this topic is that something should be done to reduce the amount of sugar these children consume.

You revise your thesis statement to look like this:

More attention should be paid to the food and beverage choices available to elementary school children.

This statement asserts your position, but the terms more attention and food and beverage choices are vague.

Use specific language . You decide to explain what you mean about food and beverage choices , so you write:

Experts estimate that half of elementary school children consume nine times the recommended daily allowance of sugar.

This statement is specific, but it isn’t a thesis. It merely reports a statistic instead of making an assertion.

Make an assertion based on clearly stated support. You finally revise your thesis statement one more time to look like this:

Because half of all American elementary school children consume nine times the recommended daily allowance of sugar, schools should be required to replace the beverages in soda machines with healthy alternatives.

Notice how the thesis answers the question, “What should be done to reduce sugar consumption by children, and who should do it?” When you started thinking about the paper, you may not have had a specific question in mind, but as you became more involved in the topic, your ideas became more specific. Your thesis changed to reflect your new insights.

How to Tell a Strong Thesis Statement from a Weak One

1. a strong thesis statement takes some sort of stand..

Remember that your thesis needs to show your conclusions about a subject. For example, if you are writing a paper for a class on fitness, you might be asked to choose a popular weight-loss product to evaluate. Here are two thesis statements:

There are some negative and positive aspects to the Banana Herb Tea Supplement.

This is a weak thesis statement. First, it fails to take a stand. Second, the phrase negative and positive aspects is vague.

Because Banana Herb Tea Supplement promotes rapid weight loss that results in the loss of muscle and lean body mass, it poses a potential danger to customers.

This is a strong thesis because it takes a stand, and because it's specific.

2. A strong thesis statement justifies discussion.

Your thesis should indicate the point of the discussion. If your assignment is to write a paper on kinship systems, using your own family as an example, you might come up with either of these two thesis statements:

My family is an extended family.

This is a weak thesis because it merely states an observation. Your reader won’t be able to tell the point of the statement, and will probably stop reading.

While most American families would view consanguineal marriage as a threat to the nuclear family structure, many Iranian families, like my own, believe that these marriages help reinforce kinship ties in an extended family.

This is a strong thesis because it shows how your experience contradicts a widely-accepted view. A good strategy for creating a strong thesis is to show that the topic is controversial. Readers will be interested in reading the rest of the essay to see how you support your point.

3. A strong thesis statement expresses one main idea.

Readers need to be able to see that your paper has one main point. If your thesis statement expresses more than one idea, then you might confuse your readers about the subject of your paper. For example:

Companies need to exploit the marketing potential of the Internet, and Web pages can provide both advertising and customer support.

This is a weak thesis statement because the reader can’t decide whether the paper is about marketing on the Internet or Web pages. To revise the thesis, the relationship between the two ideas needs to become more clear. One way to revise the thesis would be to write:

Because the Internet is filled with tremendous marketing potential, companies should exploit this potential by using Web pages that offer both advertising and customer support.

This is a strong thesis because it shows that the two ideas are related. Hint: a great many clear and engaging thesis statements contain words like because , since , so , although , unless , and however .

4. A strong thesis statement is specific.

A thesis statement should show exactly what your paper will be about, and will help you keep your paper to a manageable topic. For example, if you're writing a seven-to-ten page paper on hunger, you might say:

World hunger has many causes and effects.

This is a weak thesis statement for two major reasons. First, world hunger can’t be discussed thoroughly in seven to ten pages. Second, many causes and effects is vague. You should be able to identify specific causes and effects. A revised thesis might look like this:

Hunger persists in Glandelinia because jobs are scarce and farming in the infertile soil is rarely profitable.

This is a strong thesis statement because it narrows the subject to a more specific and manageable topic, and it also identifies the specific causes for the existence of hunger.

While Sandel argues that pursuing perfection through genetic engineering would decrease our sense of humility, he claims that the sense of solidarity we would lose is also important.

This thesis summarizes several points in Sandel’s argument, but it does not make a claim about how we should understand his argument. A reader who read Sandel’s argument would not also need to read an essay based on this descriptive thesis.  

Broad thesis (arguable, but difficult to support with evidence) 

Michael Sandel’s arguments about genetic engineering do not take into consideration all the relevant issues.

This is an arguable claim because it would be possible to argue against it by saying that Michael Sandel’s arguments do take all of the relevant issues into consideration. But the claim is too broad. Because the thesis does not specify which “issues” it is focused on—or why it matters if they are considered—readers won’t know what the rest of the essay will argue, and the writer won’t know what to focus on. If there is a particular issue that Sandel does not address, then a more specific version of the thesis would include that issue—hand an explanation of why it is important.  

Arguable thesis with analytical claim 

While Sandel argues persuasively that our instinct to “remake” (54) ourselves into something ever more perfect is a problem, his belief that we can always draw a line between what is medically necessary and what makes us simply “better than well” (51) is less convincing.

This is an arguable analytical claim. To argue for this claim, the essay writer will need to show how evidence from the article itself points to this interpretation. It’s also a reasonable scope for a thesis because it can be supported with evidence available in the text and is neither too broad nor too narrow.  

Arguable thesis with normative claim 

Given Sandel’s argument against genetic enhancement, we should not allow parents to decide on using Human Growth Hormone for their children.

This thesis tells us what we should do about a particular issue discussed in Sandel’s article, but it does not tell us how we should understand Sandel’s argument.  

Questions to ask about your thesis 

• Is the thesis truly arguable? Does it speak to a genuine dilemma in the source, or would most readers automatically agree with it?  
• Is the thesis too obvious? Again, would most or all readers agree with it without needing to see your argument?  
• Is the thesis complex enough to require a whole essay's worth of argument?  
• Is the thesis supportable with evidence from the text rather than with generalizations or outside research?  
• Would anyone want to read a paper in which this thesis was developed? That is, can you explain what this paper is adding to our understanding of a problem, question, or topic?

Thesis Statements

What this handout is about.

This handout describes what a thesis statement is, how thesis statements work in your writing, and how you can craft or refine one for your draft.

Introduction

Writing in college often takes the form of persuasion—convincing others that you have an interesting, logical point of view on the subject you are studying. Persuasion is a skill you practice regularly in your daily life. You persuade your roommate to clean up, your parents to let you borrow the car, your friend to vote for your favorite candidate or policy. In college, course assignments often ask you to make a persuasive case in writing. You are asked to convince your reader of your point of view. This form of persuasion, often called academic argument, follows a predictable pattern in writing. After a brief introduction of your topic, you state your point of view on the topic directly and often in one sentence. This sentence is the thesis statement, and it serves as a summary of the argument you’ll make in the rest of your paper.

What is a thesis statement?

A thesis statement:

• tells the reader how you will interpret the significance of the subject matter under discussion.
• is a road map for the paper; in other words, it tells the reader what to expect from the rest of the paper.
• directly answers the question asked of you. A thesis is an interpretation of a question or subject, not the subject itself. The subject, or topic, of an essay might be World War II or Moby Dick; a thesis must then offer a way to understand the war or the novel.
• makes a claim that others might dispute.
• is usually a single sentence near the beginning of your paper (most often, at the end of the first paragraph) that presents your argument to the reader. The rest of the paper, the body of the essay, gathers and organizes evidence that will persuade the reader of the logic of your interpretation.

If your assignment asks you to take a position or develop a claim about a subject, you may need to convey that position or claim in a thesis statement near the beginning of your draft. The assignment may not explicitly state that you need a thesis statement because your instructor may assume you will include one. When in doubt, ask your instructor if the assignment requires a thesis statement. When an assignment asks you to analyze, to interpret, to compare and contrast, to demonstrate cause and effect, or to take a stand on an issue, it is likely that you are being asked to develop a thesis and to support it persuasively. (Check out our handout on understanding assignments for more information.)

How do I create a thesis?

A thesis is the result of a lengthy thinking process. Formulating a thesis is not the first thing you do after reading an essay assignment. Before you develop an argument on any topic, you have to collect and organize evidence, look for possible relationships between known facts (such as surprising contrasts or similarities), and think about the significance of these relationships. Once you do this thinking, you will probably have a “working thesis” that presents a basic or main idea and an argument that you think you can support with evidence. Both the argument and your thesis are likely to need adjustment along the way.

Writers use all kinds of techniques to stimulate their thinking and to help them clarify relationships or comprehend the broader significance of a topic and arrive at a thesis statement. For more ideas on how to get started, see our handout on brainstorming .

How do I know if my thesis is strong?

If there’s time, run it by your instructor or make an appointment at the Writing Center to get some feedback. Even if you do not have time to get advice elsewhere, you can do some thesis evaluation of your own. When reviewing your first draft and its working thesis, ask yourself the following :

• Do I answer the question? Re-reading the question prompt after constructing a working thesis can help you fix an argument that misses the focus of the question. If the prompt isn’t phrased as a question, try to rephrase it. For example, “Discuss the effect of X on Y” can be rephrased as “What is the effect of X on Y?”
• Have I taken a position that others might challenge or oppose? If your thesis simply states facts that no one would, or even could, disagree with, it’s possible that you are simply providing a summary, rather than making an argument.
• Is my thesis statement specific enough? Thesis statements that are too vague often do not have a strong argument. If your thesis contains words like “good” or “successful,” see if you could be more specific: why is something “good”; what specifically makes something “successful”?
• Does my thesis pass the “So what?” test? If a reader’s first response is likely to  be “So what?” then you need to clarify, to forge a relationship, or to connect to a larger issue.
• Does my essay support my thesis specifically and without wandering? If your thesis and the body of your essay do not seem to go together, one of them has to change. It’s okay to change your working thesis to reflect things you have figured out in the course of writing your paper. Remember, always reassess and revise your writing as necessary.
• Does my thesis pass the “how and why?” test? If a reader’s first response is “how?” or “why?” your thesis may be too open-ended and lack guidance for the reader. See what you can add to give the reader a better take on your position right from the beginning.

Suppose you are taking a course on contemporary communication, and the instructor hands out the following essay assignment: “Discuss the impact of social media on public awareness.” Looking back at your notes, you might start with this working thesis:

Social media impacts public awareness in both positive and negative ways.

You can use the questions above to help you revise this general statement into a stronger thesis.

• Do I answer the question? You can analyze this if you rephrase “discuss the impact” as “what is the impact?” This way, you can see that you’ve answered the question only very generally with the vague “positive and negative ways.”
• Have I taken a position that others might challenge or oppose? Not likely. Only people who maintain that social media has a solely positive or solely negative impact could disagree.
• Is my thesis statement specific enough? No. What are the positive effects? What are the negative effects?
• Does my thesis pass the “how and why?” test? No. Why are they positive? How are they positive? What are their causes? Why are they negative? How are they negative? What are their causes?
• Does my thesis pass the “So what?” test? No. Why should anyone care about the positive and/or negative impact of social media?

After thinking about your answers to these questions, you decide to focus on the one impact you feel strongly about and have strong evidence for:

Because not every voice on social media is reliable, people have become much more critical consumers of information, and thus, more informed voters.

This version is a much stronger thesis! It answers the question, takes a specific position that others can challenge, and it gives a sense of why it matters.

Let’s try another. Suppose your literature professor hands out the following assignment in a class on the American novel: Write an analysis of some aspect of Mark Twain’s novel Huckleberry Finn. “This will be easy,” you think. “I loved Huckleberry Finn!” You grab a pad of paper and write:

Mark Twain’s Huckleberry Finn is a great American novel.

You begin to analyze your thesis:

• Do I answer the question? No. The prompt asks you to analyze some aspect of the novel. Your working thesis is a statement of general appreciation for the entire novel.

Think about aspects of the novel that are important to its structure or meaning—for example, the role of storytelling, the contrasting scenes between the shore and the river, or the relationships between adults and children. Now you write:

In Huckleberry Finn, Mark Twain develops a contrast between life on the river and life on the shore.

• Do I answer the question? Yes!
• Have I taken a position that others might challenge or oppose? Not really. This contrast is well-known and accepted.
• Is my thesis statement specific enough? It’s getting there–you have highlighted an important aspect of the novel for investigation. However, it’s still not clear what your analysis will reveal.
• Does my thesis pass the “how and why?” test? Not yet. Compare scenes from the book and see what you discover. Free write, make lists, jot down Huck’s actions and reactions and anything else that seems interesting.
• Does my thesis pass the “So what?” test? What’s the point of this contrast? What does it signify?”

After examining the evidence and considering your own insights, you write:

Through its contrasting river and shore scenes, Twain’s Huckleberry Finn suggests that to find the true expression of American democratic ideals, one must leave “civilized” society and go back to nature.

This final thesis statement presents an interpretation of a literary work based on an analysis of its content. Of course, for the essay itself to be successful, you must now present evidence from the novel that will convince the reader of your interpretation.

Developing a Thesis Statement

Many papers you write require developing a thesis statement. In this section you’ll learn what a thesis statement is and how to write one.

Keep in mind that not all papers require thesis statements . If in doubt, please consult your instructor for assistance.

What is a thesis statement?

A thesis statement . . .

• Makes an argumentative assertion about a topic; it states the conclusions that you have reached about your topic.
• Makes a promise to the reader about the scope, purpose, and direction of your paper.
• Is focused and specific enough to be “proven” within the boundaries of your paper.
• Is generally located near the end of the introduction ; sometimes, in a long paper, the thesis will be expressed in several sentences or in an entire paragraph.
• Identifies the relationships between the pieces of evidence that you are using to support your argument.

Not all papers require thesis statements! Ask your instructor if you’re in doubt whether you need one.

Identify a topic

Your topic is the subject about which you will write. Your assignment may suggest several ways of looking at a topic; or it may name a fairly general concept that you will explore or analyze in your paper.

Consider what your assignment asks you to do

Inform yourself about your topic, focus on one aspect of your topic, ask yourself whether your topic is worthy of your efforts, generate a topic from an assignment.

Below are some possible topics based on sample assignments.

Sample assignment 1

Analyze Spain’s neutrality in World War II.

Identified topic

Franco’s role in the diplomatic relationships between the Allies and the Axis

This topic avoids generalities such as “Spain” and “World War II,” addressing instead on Franco’s role (a specific aspect of “Spain”) and the diplomatic relations between the Allies and Axis (a specific aspect of World War II).

Sample assignment 2

Analyze one of Homer’s epic similes in the Iliad.

The relationship between the portrayal of warfare and the epic simile about Simoisius at 4.547-64.

This topic focuses on a single simile and relates it to a single aspect of the Iliad ( warfare being a major theme in that work).

Developing a Thesis Statement–Additional information

Your assignment may suggest several ways of looking at a topic, or it may name a fairly general concept that you will explore or analyze in your paper. You’ll want to read your assignment carefully, looking for key terms that you can use to focus your topic.

Sample assignment: Analyze Spain’s neutrality in World War II Key terms: analyze, Spain’s neutrality, World War II

After you’ve identified the key words in your topic, the next step is to read about them in several sources, or generate as much information as possible through an analysis of your topic. Obviously, the more material or knowledge you have, the more possibilities will be available for a strong argument. For the sample assignment above, you’ll want to look at books and articles on World War II in general, and Spain’s neutrality in particular.

As you consider your options, you must decide to focus on one aspect of your topic. This means that you cannot include everything you’ve learned about your topic, nor should you go off in several directions. If you end up covering too many different aspects of a topic, your paper will sprawl and be unconvincing in its argument, and it most likely will not fulfull the assignment requirements.

For the sample assignment above, both Spain’s neutrality and World War II are topics far too broad to explore in a paper. You may instead decide to focus on Franco’s role in the diplomatic relationships between the Allies and the Axis , which narrows down what aspects of Spain’s neutrality and World War II you want to discuss, as well as establishes a specific link between those two aspects.

Before you go too far, however, ask yourself whether your topic is worthy of your efforts. Try to avoid topics that already have too much written about them (i.e., “eating disorders and body image among adolescent women”) or that simply are not important (i.e. “why I like ice cream”). These topics may lead to a thesis that is either dry fact or a weird claim that cannot be supported. A good thesis falls somewhere between the two extremes. To arrive at this point, ask yourself what is new, interesting, contestable, or controversial about your topic.

As you work on your thesis, remember to keep the rest of your paper in mind at all times . Sometimes your thesis needs to evolve as you develop new insights, find new evidence, or take a different approach to your topic.

Derive a main point from topic

Once you have a topic, you will have to decide what the main point of your paper will be. This point, the “controlling idea,” becomes the core of your argument (thesis statement) and it is the unifying idea to which you will relate all your sub-theses. You can then turn this “controlling idea” into a purpose statement about what you intend to do in your paper.

Look for patterns in your evidence

Compose a purpose statement.

Consult the examples below for suggestions on how to look for patterns in your evidence and construct a purpose statement.

• Franco first tried to negotiate with the Axis
• Franco turned to the Allies when he couldn’t get some concessions that he wanted from the Axis

Possible conclusion:

Spain’s neutrality in WWII occurred for an entirely personal reason: Franco’s desire to preserve his own (and Spain’s) power.

Purpose statement

This paper will analyze Franco’s diplomacy during World War II to see how it contributed to Spain’s neutrality.

• The simile compares Simoisius to a tree, which is a peaceful, natural image.
• The tree in the simile is chopped down to make wheels for a chariot, which is an object used in warfare.

At first, the simile seems to take the reader away from the world of warfare, but we end up back in that world by the end.

This paper will analyze the way the simile about Simoisius at 4.547-64 moves in and out of the world of warfare.

Derive purpose statement from topic

To find out what your “controlling idea” is, you have to examine and evaluate your evidence . As you consider your evidence, you may notice patterns emerging, data repeated in more than one source, or facts that favor one view more than another. These patterns or data may then lead you to some conclusions about your topic and suggest that you can successfully argue for one idea better than another.

For instance, you might find out that Franco first tried to negotiate with the Axis, but when he couldn’t get some concessions that he wanted from them, he turned to the Allies. As you read more about Franco’s decisions, you may conclude that Spain’s neutrality in WWII occurred for an entirely personal reason: his desire to preserve his own (and Spain’s) power. Based on this conclusion, you can then write a trial thesis statement to help you decide what material belongs in your paper.

Sometimes you won’t be able to find a focus or identify your “spin” or specific argument immediately. Like some writers, you might begin with a purpose statement just to get yourself going. A purpose statement is one or more sentences that announce your topic and indicate the structure of the paper but do not state the conclusions you have drawn . Thus, you might begin with something like this:

• This paper will look at modern language to see if it reflects male dominance or female oppression.
• I plan to analyze anger and derision in offensive language to see if they represent a challenge of society’s authority.

At some point, you can turn a purpose statement into a thesis statement. As you think and write about your topic, you can restrict, clarify, and refine your argument, crafting your thesis statement to reflect your thinking.

As you work on your thesis, remember to keep the rest of your paper in mind at all times. Sometimes your thesis needs to evolve as you develop new insights, find new evidence, or take a different approach to your topic.

Compose a draft thesis statement

If you are writing a paper that will have an argumentative thesis and are having trouble getting started, the techniques in the table below may help you develop a temporary or “working” thesis statement.

Begin with a purpose statement that you will later turn into a thesis statement.

Assignment: Discuss the history of the Reform Party and explain its influence on the 1990 presidential and Congressional election.

Purpose Statement: This paper briefly sketches the history of the grassroots, conservative, Perot-led Reform Party and analyzes how it influenced the economic and social ideologies of the two mainstream parties.

Question-to-Assertion

If your assignment asks a specific question(s), turn the question(s) into an assertion and give reasons why it is true or reasons for your opinion.

Assignment : What do Aylmer and Rappaccini have to be proud of? Why aren’t they satisfied with these things? How does pride, as demonstrated in “The Birthmark” and “Rappaccini’s Daughter,” lead to unexpected problems?

Beginning thesis statement: Alymer and Rappaccinni are proud of their great knowledge; however, they are also very greedy and are driven to use their knowledge to alter some aspect of nature as a test of their ability. Evil results when they try to “play God.”

Write a sentence that summarizes the main idea of the essay you plan to write.

Main idea: The reason some toys succeed in the market is that they appeal to the consumers’ sense of the ridiculous and their basic desire to laugh at themselves.

Make a list of the ideas that you want to include; consider the ideas and try to group them.

• nature = peaceful
• war matériel = violent (competes with 1?)
• need for time and space to mourn the dead
• war is inescapable (competes with 3?)

Use a formula to arrive at a working thesis statement (you will revise this later).

• although most readers of _______ have argued that _______, closer examination shows that _______.
• _______ uses _______ and _____ to prove that ________.
• phenomenon x is a result of the combination of __________, __________, and _________.

What to keep in mind as you draft an initial thesis statement

Beginning statements obtained through the methods illustrated above can serve as a framework for planning or drafting your paper, but remember they’re not yet the specific, argumentative thesis you want for the final version of your paper. In fact, in its first stages, a thesis statement usually is ill-formed or rough and serves only as a planning tool.

As you write, you may discover evidence that does not fit your temporary or “working” thesis. Or you may reach deeper insights about your topic as you do more research, and you will find that your thesis statement has to be more complicated to match the evidence that you want to use.

You must be willing to reject or omit some evidence in order to keep your paper cohesive and your reader focused. Or you may have to revise your thesis to match the evidence and insights that you want to discuss. Read your draft carefully, noting the conclusions you have drawn and the major ideas which support or prove those conclusions. These will be the elements of your final thesis statement.

Sometimes you will not be able to identify these elements in your early drafts, but as you consider how your argument is developing and how your evidence supports your main idea, ask yourself, “ What is the main point that I want to prove/discuss? ” and “ How will I convince the reader that this is true? ” When you can answer these questions, then you can begin to refine the thesis statement.

Refine and polish the thesis statement

To get to your final thesis, you’ll need to refine your draft thesis so that it’s specific and arguable.

• Ask if your draft thesis addresses the assignment
• Question each part of your draft thesis
• Clarify vague phrases and assertions
• Investigate alternatives to your draft thesis

Consult the example below for suggestions on how to refine your draft thesis statement.

Sample Assignment

Choose an activity and define it as a symbol of American culture. Your essay should cause the reader to think critically about the society which produces and enjoys that activity.

• Ask The phenomenon of drive-in facilities is an interesting symbol of american culture, and these facilities demonstrate significant characteristics of our society.This statement does not fulfill the assignment because it does not require the reader to think critically about society.

Drive-ins are an interesting symbol of American culture because they represent Americans’ significant creativity and business ingenuity.

Among the types of drive-in facilities familiar during the twentieth century, drive-in movie theaters best represent American creativity, not merely because they were the forerunner of later drive-ins and drive-throughs, but because of their impact on our culture: they changed our relationship to the automobile, changed the way people experienced movies, and changed movie-going into a family activity.

While drive-in facilities such as those at fast-food establishments, banks, pharmacies, and dry cleaners symbolize America’s economic ingenuity, they also have affected our personal standards.

While drive-in facilities such as those at fast- food restaurants, banks, pharmacies, and dry cleaners symbolize (1) Americans’ business ingenuity, they also have contributed (2) to an increasing homogenization of our culture, (3) a willingness to depersonalize relationships with others, and (4) a tendency to sacrifice quality for convenience.

This statement is now specific and fulfills all parts of the assignment. This version, like any good thesis, is not self-evident; its points, 1-4, will have to be proven with evidence in the body of the paper. The numbers in this statement indicate the order in which the points will be presented. Depending on the length of the paper, there could be one paragraph for each numbered item or there could be blocks of paragraph for even pages for each one.

Complete the final thesis statement

The bottom line.

As you move through the process of crafting a thesis, you’ll need to remember four things:

• Context matters! Think about your course materials and lectures. Try to relate your thesis to the ideas your instructor is discussing.
• As you go through the process described in this section, always keep your assignment in mind . You will be more successful when your thesis (and paper) responds to the assignment than if it argues a semi-related idea.
• Your thesis statement should be precise, focused, and contestable ; it should predict the sub-theses or blocks of information that you will use to prove your argument.
• Make sure that you keep the rest of your paper in mind at all times. Change your thesis as your paper evolves, because you do not want your thesis to promise more than your paper actually delivers.

In the beginning, the thesis statement was a tool to help you sharpen your focus, limit material and establish the paper’s purpose. When your paper is finished, however, the thesis statement becomes a tool for your reader. It tells the reader what you have learned about your topic and what evidence led you to your conclusion. It keeps the reader on track–well able to understand and appreciate your argument.

How to write a thesis statement + examples

What is a thesis statement?

Is a thesis statement a question, how do you write a good thesis statement, how do i know if my thesis statement is good, examples of thesis statements, helpful resources on how to write a thesis statement, frequently asked questions about writing a thesis statement, related articles.

A thesis statement is the main argument of your paper or thesis.

The thesis statement is one of the most important elements of any piece of academic writing . It is a brief statement of your paper’s main argument. Essentially, you are stating what you will be writing about.

You can see your thesis statement as an answer to a question. While it also contains the question, it should really give an answer to the question with new information and not just restate or reiterate it.

Your thesis statement is part of your introduction. Learn more about how to write a good thesis introduction in our introduction guide .

A thesis statement is not a question. A statement must be arguable and provable through evidence and analysis. While your thesis might stem from a research question, it should be in the form of a statement.

Tip: A thesis statement is typically 1-2 sentences. For a longer project like a thesis, the statement may be several sentences or a paragraph.

A good thesis statement needs to do the following:

• Condense the main idea of your thesis into one or two sentences.
• Answer your project’s main research question.
• Clearly state your position in relation to the topic .
• Make an argument that requires support or evidence.

Once you have written down a thesis statement, check if it fulfills the following criteria:

• Your statement needs to be provable by evidence. As an argument, a thesis statement needs to be debatable.
• Your statement needs to be precise. Do not give away too much information in the thesis statement and do not load it with unnecessary information.
• Your statement cannot say that one solution is simply right or simply wrong as a matter of fact. You should draw upon verified facts to persuade the reader of your solution, but you cannot just declare something as right or wrong.

As previously mentioned, your thesis statement should answer a question.

If the question is:

What do you think the City of New York should do to reduce traffic congestion?

A good thesis statement restates the question and answers it:

In this paper, I will argue that the City of New York should focus on providing exclusive lanes for public transport and adaptive traffic signals to reduce traffic congestion by the year 2035.

Here is another example. If the question is:

How can we end poverty?

A good thesis statement should give more than one solution to the problem in question:

In this paper, I will argue that introducing universal basic income can help reduce poverty and positively impact the way we work.

• The Writing Center of the University of North Carolina has a list of questions to ask to see if your thesis is strong .

A thesis statement is part of the introduction of your paper. It is usually found in the first or second paragraph to let the reader know your research purpose from the beginning.

In general, a thesis statement should have one or two sentences. But the length really depends on the overall length of your project. Take a look at our guide about the length of thesis statements for more insight on this topic.

Here is a list of Thesis Statement Examples that will help you understand better how to write them.

Every good essay should include a thesis statement as part of its introduction, no matter the academic level. Of course, if you are a high school student you are not expected to have the same type of thesis as a PhD student.

Here is a great YouTube tutorial showing How To Write An Essay: Thesis Statements .

OASIS: Writing Center

Writing a paper: thesis statements, basics of thesis statements.

The thesis statement is the brief articulation of your paper's central argument and purpose. You might hear it referred to as simply a "thesis." Every scholarly paper should have a thesis statement, and strong thesis statements are concise, specific, and arguable. Concise means the thesis is short: perhaps one or two sentences for a shorter paper. Specific means the thesis deals with a narrow and focused topic, appropriate to the paper's length. Arguable means that a scholar in your field could disagree (or perhaps already has!).

Strong thesis statements address specific intellectual questions, have clear positions, and use a structure that reflects the overall structure of the paper. Read on to learn more about constructing a strong thesis statement.

Being Specific

This thesis statement has no specific argument:

Needs Improvement: In this essay, I will examine two scholarly articles to find similarities and differences.

This statement is concise, but it is neither specific nor arguable—a reader might wonder, "Which scholarly articles? What is the topic of this paper? What field is the author writing in?" Additionally, the purpose of the paper—to "examine…to find similarities and differences" is not of a scholarly level. Identifying similarities and differences is a good first step, but strong academic argument goes further, analyzing what those similarities and differences might mean or imply.

Better: In this essay, I will argue that Bowler's (2003) autocratic management style, when coupled with Smith's (2007) theory of social cognition, can reduce the expenses associated with employee turnover.

The new revision here is still concise, as well as specific and arguable.  We can see that it is specific because the writer is mentioning (a) concrete ideas and (b) exact authors.  We can also gather the field (business) and the topic (management and employee turnover). The statement is arguable because the student goes beyond merely comparing; he or she draws conclusions from that comparison ("can reduce the expenses associated with employee turnover").

Making a Unique Argument

This thesis draft repeats the language of the writing prompt without making a unique argument:

Needs Improvement: The purpose of this essay is to monitor, assess, and evaluate an educational program for its strengths and weaknesses. Then, I will provide suggestions for improvement.

You can see here that the student has simply stated the paper's assignment, without articulating specifically how he or she will address it. The student can correct this error simply by phrasing the thesis statement as a specific answer to the assignment prompt.

Better: Through a series of student interviews, I found that Kennedy High School's antibullying program was ineffective. In order to address issues of conflict between students, I argue that Kennedy High School should embrace policies outlined by the California Department of Education (2010).

Words like "ineffective" and "argue" show here that the student has clearly thought through the assignment and analyzed the material; he or she is putting forth a specific and debatable position. The concrete information ("student interviews," "antibullying") further prepares the reader for the body of the paper and demonstrates how the student has addressed the assignment prompt without just restating that language.

Creating a Debate

This thesis statement includes only obvious fact or plot summary instead of argument:

Needs Improvement: Leadership is an important quality in nurse educators.

A good strategy to determine if your thesis statement is too broad (and therefore, not arguable) is to ask yourself, "Would a scholar in my field disagree with this point?" Here, we can see easily that no scholar is likely to argue that leadership is an unimportant quality in nurse educators.  The student needs to come up with a more arguable claim, and probably a narrower one; remember that a short paper needs a more focused topic than a dissertation.

Better: Roderick's (2009) theory of participatory leadership  is particularly appropriate to nurse educators working within the emergency medicine field, where students benefit most from collegial and kinesthetic learning.

Here, the student has identified a particular type of leadership ("participatory leadership"), narrowing the topic, and has made an arguable claim (this type of leadership is "appropriate" to a specific type of nurse educator). Conceivably, a scholar in the nursing field might disagree with this approach. The student's paper can now proceed, providing specific pieces of evidence to support the arguable central claim.

Choosing the Right Words

This thesis statement uses large or scholarly-sounding words that have no real substance:

Needs Improvement: Scholars should work to seize metacognitive outcomes by harnessing discipline-based networks to empower collaborative infrastructures.

There are many words in this sentence that may be buzzwords in the student's field or key terms taken from other texts, but together they do not communicate a clear, specific meaning. Sometimes students think scholarly writing means constructing complex sentences using special language, but actually it's usually a stronger choice to write clear, simple sentences. When in doubt, remember that your ideas should be complex, not your sentence structure.

Better: Ecologists should work to educate the U.S. public on conservation methods by making use of local and national green organizations to create a widespread communication plan.

Notice in the revision that the field is now clear (ecology), and the language has been made much more field-specific ("conservation methods," "green organizations"), so the reader is able to see concretely the ideas the student is communicating.

Leaving Room for Discussion

This thesis statement is not capable of development or advancement in the paper:

Needs Improvement: There are always alternatives to illegal drug use.

This sample thesis statement makes a claim, but it is not a claim that will sustain extended discussion. This claim is the type of claim that might be appropriate for the conclusion of a paper, but in the beginning of the paper, the student is left with nowhere to go. What further points can be made? If there are "always alternatives" to the problem the student is identifying, then why bother developing a paper around that claim? Ideally, a thesis statement should be complex enough to explore over the length of the entire paper.

Better: The most effective treatment plan for methamphetamine addiction may be a combination of pharmacological and cognitive therapy, as argued by Baker (2008), Smith (2009), and Xavier (2011).

In the revised thesis, you can see the student make a specific, debatable claim that has the potential to generate several pages' worth of discussion. When drafting a thesis statement, think about the questions your thesis statement will generate: What follow-up inquiries might a reader have? In the first example, there are almost no additional questions implied, but the revised example allows for a good deal more exploration.

Thesis Mad Libs

If you are having trouble getting started, try using the models below to generate a rough model of a thesis statement! These models are intended for drafting purposes only and should not appear in your final work.

• In this essay, I argue ____, using ______ to assert _____.
• While scholars have often argued ______, I argue______, because_______.
• Through an analysis of ______, I argue ______, which is important because_______.

Words to Avoid and to Embrace

When drafting your thesis statement, avoid words like explore, investigate, learn, compile, summarize , and explain to describe the main purpose of your paper. These words imply a paper that summarizes or "reports," rather than synthesizing and analyzing.

Instead of the terms above, try words like argue, critique, question , and interrogate . These more analytical words may help you begin strongly, by articulating a specific, critical, scholarly position.

5 Tips for Writing a Strong Thesis Statement

• 5-minute read
• 15th January 2021

Every good research paper needs a strong thesis statement. Typically, this is a line or two near the start where you set out the basic idea or argument that you will explore. But how do you write a perfect thesis statement? We have five top tips:

• Think about the type of paper you are writing.
• Come up with a question that your paper will answer.
• Answer your question to work out a point you can argue or defend.
• Summarize the key arguments or points you will make.
• Review your thesis statement after writing your paper.

For more advice on all the above, read our guide below, or watch our video:

1. Tailor Your Thesis Statement to Your Paper Type

Different papers may require different approaches to writing a thesis statement. Three common paper types are argumentative, expository, and analytical:

• Argumentative – An argumentative thesis statement sets out the position you will argue for and outlines the key point(s) from your paper.
• Expository – Expository essays explain something, so the thesis statement for a paper like this will summarize the key facts from your research.
• Analytical – Analytical essays focus on breaking down and exploring an issue in depth, so the thesis statement will summarize the issue and your analysis.

Thus, before writing anything, work out what kind of paper you’re writing. Once you’ve done this, you can tailor your thesis statement to match. We’ll give examples of argumentative, expository, and analytical thesis statements below.

2. Start with a Question

To work out a basic thesis, you need to start with an essay question. This is the issue your paper will address, and thus the main subject for your thesis statement.

If you were assigned a question for the paper, this will be simple! Otherwise, think about the topic of your paper and work out a simple question that you will answer.

You can see some examples of possible essay questions below:

• Argumentative – Should vaccination for measles be compulsory or voluntary?
• Expository – What effect did the Great Depression have on the US economy?
• Analytical – What is the role of the “play within a play” in Hamlet?

This question will provide a jumping off point for your full thesis statement.

3. Work Out a Position You Can Defend

When you have a question, sketch out a basic answer for it. Importantly, this has to be something someone could disagree with or take a differing position on.

For instance, simply saying “The Great Depression had a major effect on the economy” would not be enough. This is too obvious. Instead, try to think of as position that someone could rationally dispute or disagree with. For example:

• Argumentative – Vaccination for measles should be compulsory.
• Expository – The Great Depression significantly reduced GDP in the USA, triggering a shift to a mixed economy.
• Analytical – Shakespeare uses the “play within a play” in Hamlet to explore the relationship between performance and authenticity.

This will become the basic thesis you will expand on or defend in your paper.

4. Summarize Your Key Arguments

A strong thesis statement will be clear and concise (a sentence or two at most). But it should also be detailed enough to show how you will answer your essay question.

Thus, when you have your basic thesis, you will want to expand it to summarize the key points or arguments you will use to support it. For instance:

• Argumentative – Vaccination for measles should be compulsory because research shows it has saved millions of lives with few negative side effects.
• Expository – The Great Depression reduced GDP in the US by 50% within the first five years, triggering a shift to New Deal politics and a mixed economy.
• Analytical – Shakespeare uses the “play within a play” in Hamlet to explore themes of performance and authenticity, including the reliability of external appearances and how performance shapes our lives.

Your thesis statement should now give a strong sense of what you will say in the rest of your paper, setting up the reader to follow your arguments.

5. Review Your Thesis After Writing Your Paper

The thesis statement always goes at the start of a paper, so it may be one of the first things you write. But it is worth revisiting your thesis once you have a first draft.

This is because you need your thesis statement to reflect the content of the paper as a whole. And if the focus of your work shifts during writing – perhaps because you found a new piece of evidence or thought of a new argument at some point – you may find your conclusion and your initial thesis don’t quite match up any more.

When you have a first draft, though, you can tweak your thesis statement to reflect any changes made while drafting (or tweak your paper to match the statement).

1.8: How to Write a Thesis Statement

• Last updated
• Save as PDF
• Page ID 22474

Whether you are writing a short essay or a doctoral dissertation, your thesis statement will arguably be the most difficult sentence to formulate. An effective thesis statement states the purpose of the paper and, therefore, functions to control, assert and structure your entire  argument . Without a sound thesis, your argument may sound weak, lacking in direction, and  uninteresting to the reader.

Start with a question — then make the answer your thesis

Regardless of how complicated the subject is, almost any thesis can be constructed by answering a question.

• Thesis: “Computers allow fourth graders an early advantage in technological and scientific education.”
• Question: “Why is the Mississippi River so important in Mark Twain’s Huckleberry Finn ?” Thesis: “The river comes to symbolize both division and progress, as it separates our characters and country while still providing the best chance for Huck and Jim to get to know one another.”

Tailor your thesis to the type of paper you’re writing

N ot all essays persuade, and not all essays teach. The goals of your paper will help you find the best thesis.

• Analytical: Breaks down something to better examine and understand it. Ex. “This dynamic between different generations sparks much of the play’s tension, as age becomes a motive for the violence and unrest that rocks King Lear.”

Ensure your thesis is provable

Good Theses Examples:

• “By owning up to the impossible contradictions, embracing them and questioning them, Blake forges his own faith, and is stronger for it. Ultimately, the only way for his poems to have faith is to temporarily lose it.”
• “According to its well-documented beliefs and philosophies, an existential society with no notion of either past or future cannot help but become stagnant.”
• “By reading “Ode to a Nightingale” through a modern deconstructionist lens, we can see how Keats viewed poetry as shifting and subjective, not some rigid form.”

Bad Theses Examples:

• “The wrong people won the American Revolution.” While striking and unique, who is “right” and who is “wrong” is exceptionally hard to prove, and very subjective.
• “The theory of genetic inheritance is the binding theory of every human interaction.” Too complicated and overzealous. The scope of “every human interaction” is just too big
• “Paul Harding’s novel Tinkers is ultimately a cry for help from a clearly depressed author.” Unless you interviewed Harding extensively, or had a lot of real-life sources, you have no way of proving what is fact and what is fiction.”

Get the sound right

Example thesis statements with good statement language include:

• “Because of William the Conqueror’s campaign into England, that nation developed the strength and culture it would need to eventually build the British Empire.”
• “Hemingway significantly changed literature by normalizing simplistic writing and frank tone.”

Know where to place a thesis statement

Because of the role thesis statements play, they appear at the beginning of the paper, usually at the end of the first paragraph or somewhere in the introduction. Although most people look for the thesis at the end of the first paragraph, its location can depend on a number of factors such as how lengthy of an introduction you need before you can introduce your thesis or the length of your paper.

Limit a thesis statement to one or two sentences in length

Thesis statements are clear and to the point, which helps the reader identify the topic and direction of the paper, as well as your position towards the subject.

These OWL resources will help you develop and refine the arguments in your writing.

The thesis statement or main claim must be debatable

An argumentative or persuasive piece of writing must begin with a debatable thesis or claim. In other words, the thesis must be something that people could reasonably have differing opinions on. If your thesis is something that is generally agreed upon or accepted as fact then there is no reason to try to persuade people.

Example of a non-debatable thesis statement:

This thesis statement is not debatable. First, the word pollution implies that something is bad or negative in some way. Furthermore, all studies agree that pollution is a problem; they simply disagree on the impact it will have or the scope of the problem. No one could reasonably argue that pollution is unambiguously good.

Example of a debatable thesis statement:

This is an example of a debatable thesis because reasonable people could disagree with it. Some people might think that this is how we should spend the nation's money. Others might feel that we should be spending more money on education. Still others could argue that corporations, not the government, should be paying to limit pollution.

Another example of a debatable thesis statement:

In this example there is also room for disagreement between rational individuals. Some citizens might think focusing on recycling programs rather than private automobiles is the most effective strategy.

The thesis needs to be narrow

Although the scope of your paper might seem overwhelming at the start, generally the narrower the thesis the more effective your argument will be. Your thesis or claim must be supported by evidence. The broader your claim is, the more evidence you will need to convince readers that your position is right.

Example of a thesis that is too broad:

There are several reasons this statement is too broad to argue. First, what is included in the category "drugs"? Is the author talking about illegal drug use, recreational drug use (which might include alcohol and cigarettes), or all uses of medication in general? Second, in what ways are drugs detrimental? Is drug use causing deaths (and is the author equating deaths from overdoses and deaths from drug related violence)? Is drug use changing the moral climate or causing the economy to decline? Finally, what does the author mean by "society"? Is the author referring only to America or to the global population? Does the author make any distinction between the effects on children and adults? There are just too many questions that the claim leaves open. The author could not cover all of the topics listed above, yet the generality of the claim leaves all of these possibilities open to debate.

Example of a narrow or focused thesis:

In this example the topic of drugs has been narrowed down to illegal drugs and the detriment has been narrowed down to gang violence. This is a much more manageable topic.

We could narrow each debatable thesis from the previous examples in the following way:

Narrowed debatable thesis 1:

This thesis narrows the scope of the argument by specifying not just the amount of money used but also how the money could actually help to control pollution.

Narrowed debatable thesis 2:

This thesis narrows the scope of the argument by specifying not just what the focus of a national anti-pollution campaign should be but also why this is the appropriate focus.

Qualifiers such as " typically ," " generally ," " usually ," or " on average " also help to limit the scope of your claim by allowing for the almost inevitable exception to the rule.

Types of claims

Claims typically fall into one of four categories. Thinking about how you want to approach your topic, or, in other words, what type of claim you want to make, is one way to focus your thesis on one particular aspect of your broader topic.

Claims of fact or definition: These claims argue about what the definition of something is or whether something is a settled fact. Example:

Claims of cause and effect: These claims argue that one person, thing, or event caused another thing or event to occur. Example:

Claims about value: These are claims made of what something is worth, whether we value it or not, how we would rate or categorize something. Example:

Claims about solutions or policies: These are claims that argue for or against a certain solution or policy approach to a problem. Example:

Which type of claim is right for your argument? Which type of thesis or claim you use for your argument will depend on your position and knowledge of the topic, your audience, and the context of your paper. You might want to think about where you imagine your audience to be on this topic and pinpoint where you think the biggest difference in viewpoints might be. Even if you start with one type of claim you probably will be using several within the paper. Regardless of the type of claim you choose to utilize it is key to identify the controversy or debate you are addressing and to define your position early on in the paper.

An Overview of the Writing Process

Whether you are writing a short essay or a doctoral dissertation, your thesis statement will arguably be the most difficult sentence to formulate.

• Thesis: “Through careful sociological study, we’ve found that people naturally assume that “morally righteous” people look down on them as “inferior,” causing anger and conflict where there generally is none.”

Tailor your thesis to the type of paper you’re writing

N ot all essays persuade, and not all essays teach. The goals of your paper will help you find the best thesis.

• Ex. “This dynamic between different generations sparks much of the play’s tension, as age becomes a motive for the violence and unrest that rocks King Lear.”
• Ex. “The explosion of 1800’s philosophies like Positivism, Marxism, and Darwinism undermined and refuted Christianity to instead focus on the real, tangible world.”
• Ex. “Without the steady hand and specific decisions of Barack Obama, America would never have recovered from the hole it entered in the early 2000’s.”

How to Come up With a Thesis

Last Updated: January 29, 2023

This article was co-authored by Christopher Taylor, PhD . Christopher Taylor is an Adjunct Assistant Professor of English at Austin Community College in Texas. He received his PhD in English Literature and Medieval Studies from the University of Texas at Austin in 2014. This article has been viewed 126,511 times.

All students, whether in high school or college, need to write standard expository (explanatory) or persuasive essays. Each essay must include a thesis statement. A thesis statement is your main point and is presented as an argument. Writing a thesis statement involves answering the main question and doing a bit of research to make sure your thesis can be backed up.

Understanding Your Topic

• Think about your assignment topic. What are you expected to write about? Then take this topic and make it a question you can answer. [1] X Research source
• For example, if you are assigned a paper or report on explaining the safety benefits of buckling your seatbelt in the car, make it into a question you can answer.
• Your topic becomes “What are the safety benefits of buckling your seatbelt?”
• The answer to this question is the beginning of your thesis statement.

• Knowing what kind of paper you’re writing will further help you construct a quality thesis. Though you may be writing a paper about World War II or The Great Gatsby, your statement should contain similar attributes.
• A good thesis statement answers the question asked of you. It’s your interpretation of the subject. It should aim to make a claim that others can dispute.
• Your thesis should also express one main idea that can be developed enough to cover all parts of the assignment.

• Whether you’re given a broad assignment like a paper on The Great Gatsby, or a more specific topic like the benefits of wearing seatbelts, you need to take a side and explain it clearly.
• Break down your topic into an argument that you can adequately speak about. For example, if your topic is about the benefits of seatbelts, you have many points of view to explore. You can take a broader route and decide to talk about the decrease in fatal accidents since seatbelts became required. Or, you can get more specific and discuss the laws about wearing your seatbelt in the back seat. Your argument right now is that seatbelts save lives.
• Consider a variety of viewpoints before settling on your thesis. Your argument may be that seatbelts don’t provide any new benefits. This side may be harder to argue in such a broad area, however. Because there may be a lot of information against you, you may consider getting more specific. You may consider arguing that seatbelt technology hasn’t improved safety in X amount of time. You may find that there is more information on the advancement of other vehicle safety measures which has progressed much farther than seatbelts.
• If your topic is even broader, like a report on The Great Gatsby, you have to find an angle that you can argue about or what intrigues you about the book. Perhaps after reading the book, you became interested in how American consumerism and monetary pride led to the Great Depression.
• Tailor how specific your topic is based on the required length of your paper. If you have a longer paper, you may want to explore a topic broadly, but for a shorter paper, you may need to be very specific.

• You might have the question: “What are the real world ramifications of the themes presented in The Great Gatsby?”
• Therefore, you begin with this conclusion written as a sentence: “The monetary pride and dichotomy of old and new money depicted in The Great Gatsby led to the Great Depression”. This isn’t your thesis statement yet. This isn’t a well enough formed argument, but it allows you to have a starting opinion and main idea.
• Remember that you want to take a stance that reasonable people could argue. This doesn’t mean that you have to take an unpopular opinion, but you should be able to create a conversation with your thesis.

• You have already begun to do this by finding your point of view. However, your argument isn’t fully formed yet.
• After you come up with your idea, do a little research to see if you have enough credible information to back it up.
• Perhaps you look up seatbelt statistics and find that there isn’t enough information to argue that seatbelt technology hasn’t improved enough. Or, that there isn’t enough information to provide a counterargument. While researching, you read about front seat seatbelts and rear seat seatbelts. You then decide your argument is that backseat passengers should be required to wear seatbelts. Seatbelts are not always required to be worn in the back seat depending on the region. You find this topic has enough information to explore.
• Now write down a few different sentence options that argue your point of view. Try to make a slightly different point in each sentence. One sentence may be: “Backseat passengers should be required to wear seatbelts at all times.” Another could be: “Not wearing your seatbelt in the backseat increases the risk of serious injury by X percent.”
• If you are writing about a broader topic, like your book report on the Great Gatsby, you may find through research that your current argument is too hypothetical. You may not find enough factual correlation to support your topic in the context of your paper’s requirements. Further research is required to support or change your argument.

Gathering Information and Brainstorming

• If you decide to argue that seatbelts should be worn in the back seat, find sources that give you crash and safety statistics. Look for articles and facts that argue both sides of the argument.
• If you’re writing about the themes of consumerism and pride depicted in The Great Gatsby serving as a roadmap to the Great Depression, research causes of the Great Depression. Do further research to see if other people have a similar argument to yours. See how other similar topics and articles go about relating the actual story in The Great Gatsby to the Great Depression.

• With enough information to back up your thesis, it’s time to go back to what you have written already and see what you may need to change about it. Perhaps your research gave you a new angle to include.
• While you previously had “Backseat passengers should be required to wear seatbelts at all times,” you realize that this doesn’t fulfill all of the requirements of your thesis. Though you have a solid argument, you haven’t fully answered your question.
• The question: “What are the benefits of buckling your seatbelt?” still needs to be addressed. Look through your research to find some specific stats to back up your statement.

• While “Backseat passengers should be required to wear seatbelts at all times,” expresses your opinion, it doesn’t provide an argument yet that someone can really contest.
• Get specific with the “why’s” or “what’s”. “Due to X percent of unbelted backseat passengers being ejected and fatally wounded in car accidents, backseat passengers should be required to buckle up at all times.” is a more structured thesis that provides a “why”.
• The same applies to your potential book report. “The monetary pride and dichotomy of old and new money depicted in The Great Gatsby led to the Great Depression.” doesn’t exactly offer a specific interpretation of the literary work. Consider, “The fear of muddled class systems and the pursuit of the American Dream depicted in The Great Gatsby led to an age of consumerism and excess, which triggered The Great Depression.” This sentence more clearly defines your stance. It also passes the “So what?” test because you have outlined a controversial point of view which presents an interpretation of the literature.

• Getting more specific in your thesis is good, but it can sometimes cause you to wander as you try to incorporate everything you want to say. Remember, your thesis is a one-sentence introduction that gives an outline for the body of your paper.
• You don’t have to include every little detail you will touch on in your thesis. It should provide a well-structured overview.
• If your original question is “What are the safety benefits of buckling your seatbelt?” read over your current thesis and see if it still answers that question. “Due to X percent of unbelted backseat passengers being ejected and fatally wounded in car accidents, backseat passengers should be required to buckle up at all times.” Your current thesis doesn’t exactly answer this question, so it’s time to revise it again.
• “What are the real world ramifications of the themes presented in The Great Gatsby?” is answered in our current statement: “The fear of muddled class systems and the pursuit of the American Dream depicted in The Great Gatsby led to an age of consumerism and excess, which triggered The Great Depression.” However, we can still revise and tighten our statement.

Finalizing Your Thesis Statement

• Your thesis is a statement that others may hold a different opinion about. And which you will develop in your essay to show why you have this point of view.
• Check to make sure your thesis contains an argument that hits on the focus of your question.
• Revising your seatbelt thesis to: “Increasing seatbelt laws to include mandatory buckling in back seats will provide further safety benefits by reducing the percentage of fatalities in vehicle accidents.” better answers your original question.

• While “The fear of muddled class systems and the pursuit of the American Dream depicted in The Great Gatsby led to an age of consumerism and excess, which triggered The Great Depression.” answers your question, it’s slightly broad.
• “The themes of wealth disparity in American royalty, and pursuit of the American Dream presented in The Great Gatsby depict a parallel to real-world consumerism and excess which led to the Great Depression.” narrows down that you will talk about specific themes in the book and compare these fictional themes to the real world.
• This is also an example of a thesis statement which can be broken up into two sentences.

• If your assignment was to discuss the benefits of seatbelts, read your thesis again and ask yourself if it can cover the criteria.
• “Increasing seatbelt laws to include mandatory buckling in back seats will provide further safety benefits by reducing the percentage of fatalities in vehicle accidents.” In this thesis, you have taken a position that can be argued.
• You have made it specific by narrowing your topic a particular aspect of seatbelt safety. And you have given an answer to how your argument will discuss the benefits of seatbelts.

• Before beginning your paper, make sure you have fulfilled all the criteria. Do you answer a question? Are you taking a position others can challenge or oppose? Is your thesis specific enough? Does it pass the “So what?” and “how and why?” test.
• If your thesis doesn’t fulfill these requirements, take a break and then go back and revise. Sometimes, after taking a step back, you can come back with a better angle.
• As you write your essay, follow your thesis and outline, but don’t feel that you have to compromise your paper to fit your thesis. If you find yourself needing to revise your thesis throughout your essay, do so.

‘A completely different game’: Faculty, students harness AI in the classroom

Grace Honeyman ’26 describes her final project, made with AI, for Juan Hinestroza’s class “Textiles, Apparel and Innovation Design” in fall 2023.

By Susan Kelley, Cornell Chronicle

For 15 years, Professor Juan Hinestroza had been teaching his course on innovative textiles essentially the same way. But last fall, he changed it up, requiring his students to use generative AI.

In the past, the final project took a five-student team two months to finish. Last semester, each student working alone with AI did it in two weeks – with superior results.

Documenting their progress with blog posts, the students used AI tools to summarize research papers, then used that information to update an existing design that applies innovative textiles to a garment or object to solve a real-world problem. Some improved gloves that ease arthritis. Others updated shoes that convert the wearer’s movement to energy that warms the feet of people with diabetes. They also used the tools to create images of their designs. For the final research posters, they used only AI for imagery, text and references.

Juan Hinestroza, the Rebecca Q. Morgan ’60 Professor of Fiber Science and Apparel Design in the College of Human Ecology, has embraced the use of AI in his courses.

“AI really liberated them to dig deeper. It’s like a calculator: You can spend your time doing your calculations by hand. But if you have a calculator, then you can spend more time doing something else,” said Hinestroza, the Rebecca Q. Morgan ’60 Professor of Fiber Science and Apparel Design in the College of Human Ecology (CHE).

He is one of many faculty members across Cornell’s colleges and disciplines who are embracing AI’s capabilities and limitations in their classrooms.

To be sure, some faculty members do not allow the use of AI in their courses; a university committee initiated by Provost Michael I. Kotlikoff offered faculty guidance on the use of AI in the classroom in fall 2023.

“I tell my colleagues, especially those who are opposed to these tools, that you cannot teach the same way you were taught. Because it’s a completely different game,” Hinestroza said. “The reality is that these tools are being used by companies. They’re being used by other universities. So you have to train the students for the real world. The world that we as faculty members think exists – it doesn’t exist anymore.”

Hinestroza is one of five winners of the 2024 Teaching Innovation Awards (see sidebar). They will discuss their approaches at the Provost’s Teaching Innovation Showcase: Creative Responses to Generative AI, on April 11.

“The award winners, and other applicants as well, represent a wide and impressive range of responses to the new challenges and opportunities associated with generative AI in the classroom,” said Steven Jackson, vice provost for academic innovation. “They provide more great evidence of the skill and imagination of Cornell teachers in responding to ongoing changes in the teaching environment.”

‘We’re going to experiment’

Grace Honeyman ’26 had minimal experience with AI prior to taking Hinestroza’s course, “Textiles, Apparel and Innovation Design.” She had never even opened a ChatGPT account on her computer.

Grace Honeyman ’26 gave the AI platform Midjourney the prompt “create a schematic image of an elderly man wearing a piezoelectric nanogenerator embedded textile for medical monitoring” to create this image.

The course introduced her and other students to AI tools that can create images and interpret scientific literature, including ChatGPT, Midjourney, BingChat, Claude.ai, DALL-E, Jasper.ai and Adobe’s Firefly and Sensei. “I told them, ‘I’m learning as you are. And we’re going to experiment,’” Hinestroza said. “The students were incredibly patient and played along as we made mistakes and found ways to optimize the use of tools.”

For her final project, Honeyman redesigned a medical undershirt, which reads the vital signs of people with congestive heart failure, to include a piezoelectric nanogenerator that converts the kinetic energy of the wearer’s movement into electrical energy within the textile, eliminating the need for a bulky battery pack.

Nancy Wang ’24 used the AI DALL-E3 and the prompt “create a schematic of one layer of flexible battery, one layer of woven conductive thread, and one layer of textile” to create this image.

She fed a series of prompts into Midjourney and Bing.AI, which eventually created images that matched what she had in mind. “I don’t have time to do a five-hour Photoshop tutorial and put together a schematic of what my textile looks like,” she said. “Doing that on DALL-E or Midjourney take five or 10 minutes, depending on how long it takes you to type in your prompt.”

That gave her more time to research how to update the technology, textile applications and intended use. “A lot of what people are missing is that students start with an image in our minds,” she said. “It’s not really all being done by AI – we still have to use our creativity.”

And they had to watch out for the tools’ mistakes. Sometimes AI creates images of a hand, for example, that has only three fingers, or “hallucinates” research papers that don’t exist.

“Honestly, being very, very critical of all this technology is one of the most important skills to learn and one of the most important things I did learn from this class,” Honeyman said.

‘The genie is out of the bottle’

A few major AI image-generating tools were released about a month before Jennifer Birkeland , assistant professor of landscape architecture in the College of Agriculture and Life Sciences, started teaching her course on graphic communication.

And she had heard many professionals in landscape architecture were using them already, so she started playing around with the tools herself. “I was like, ‘Oh, this is really weird and interesting. This is a really critical tool. I need to incorporate this somehow into my class,’” she said.

Matthew Sprague, MLA ’26, used Midjourney AI to create this digital landscape for a class on graphic communication in the College of Agriculture and Life Sciences.

Her students wrote a series of prompts to make the tools create an image that they’d work with for the rest of the semester. They used Rhinoceros 3D, a modeling software, to create 3D models and then cross-sections of the object, and further iterations through the traditional design process.

She aimed to teach students to think critically and become AI literate. “It’s two-sided,” Birkeland said. “Yes, AI is cool and smart, but it’s also dumb.”

For example, she asked students to use one prompt with different AI tools and compare the results. The exercise demonstrated that each tool draws from a different library of data to generate images – and often include racial and gender biases. “I asked, ‘Did you get only men in this one? Or did you only get white men, versus another tool that might have had something else?’” Birkeland said.

The tools are helping Matthew Sprague, MLA ’26, learn to recognize good design, he said. The images AI tools create are “pretty peculiar and strange-looking, mostly,” he said. “It makes you think about style and what visually works or doesn’t. And you can identify some of that in your own work. You need to have some design skills to take that and make it look right.”

Matthew Sprague, MLA ’26, used Midjourney AI to create this image of an urban garden for a class on graphic communication in the College of Agriculture and Life Sciences.

The tools have other limitations. For example, they wouldn’t be able to do assignments for his main studio class, Sprague said. “If I tried to tell it to make those drawings, it wouldn’t have any clue what I was talking about, especially with architectural drawings that need to be precise. It’s not there yet.”

But the tools do level the playing field for students who don’t have a fine-art background, Birkeland said. “People who don’t draw are now able to generate these images, and then use them as references to show people what they’re envisioning.”

Given the increasing use of AI, instructors have a responsibility to teach students how to use it, Birkeland said. “Whether we like it or not, it’s not going away – not at this point. The genie is out of the bottle.”

Transformative change

In the government class “America Confronts the World,” students treated large language models like ChatGPT as interlocutors that supported, rather than substituted for, original writing.

“After attending Center for Teaching Innovation workshops and consulting instructor reflections, we implemented a two-pronged approach that required responsible yet creative student engagement with AI,” said Peter Katzenstein , the Walter S. Carpenter, Jr. Professor of International Studies in the College of Arts and Sciences. He collaborated with his teaching assistants – doctoral candidates Amelia C. Arsenault, M.A. ’23, and Musckaan Chauhan, M.A. ’23 – to integrate AI into the classwork.

“This is a tool that students are using already, and it’s probably not going away,” said Arsenault, whose research focuses on surveillance technologies, which rely heavily on AI. “We thought this would be an opportunity for us to teach them how to use it in a way that was actually most useful for them.”

2024 Teaching Innovation Award

Five faculty members have been honored with the 2024 Teaching Innovation Award, sponsored by the Vice Provost for Academic Innovation and the Center for Teaching Innovation . This year’s theme, “Creative Responses to Generative Artificial Intelligence,” recognizes creative approaches from the last year developed in response to generative AI.

Award winners will present their experiences at the Provost’s Teaching Innovation Showcase: Creative Responses to Generative AI, on April 11. The winners will collaborate with CTI to share their experiences with colleagues.

The winners:

• Jennifer Birkeland , assistant professor of landscape architecture, College of Agriculture and Life Sciences;
• Tracy Carrick , senior lecturer, John S. Knight Institute for Writing in the Disciplines, College of Arts & Sciences (A&S);
• Juan Hinestroza , the Rebecca Q. Morgan ’60 Professor of Fiber Science and Apparel Design, College of Human Ecology;
• Peter Katzenstein , the Walter S. Carpenter, Jr. Professor of International Studies, Department of Government, A&S; and
• Amie Patchen , lecturer, Department of Public and Ecosystem Health, College of Veterinary Medicine.

The course focuses on the wide range of views at play in American politics and foreign policy. Four written assignments integrated AI, while four had non-AI prompts.

In one assignment, students wrote an essay based on class readings and then brainstormed an objecting argument; in another, they fed their essay into an AI tool and asked it to come up with an objecting argument that they then counterargued to strengthen their thesis. Throughout the course, the students did reflections on their experiences with AI.

“The students appreciated that we were willing to deal with it in some way, shape or form,” Arsenault said.

Esteban Lau ’25, a government major in A&S, was surprised to find that when he prompted the AI tool to counter his essay, it argued for his point instead. Like other students, he found he had to try several different prompts to get the result he wanted. “I guess that comes down to what people call ‘prompt engineering.’ I’m actually getting better at using the AI tool,” he said.

“But at the same time, I think there’s a lot of value in not using them and developing your own analytical thought,” he said. “And it’s a difficult balance to strike because, you know, some students do use AI writing as a crutch, and they rely on it too heavily. And I think that impacts their education.”

Increasingly there are tools that purport to identify when a student has cheated and used an AI tool to write their essay, but they are highly unreliable, Arsenault said. “Rather than getting yourself in that position where you have to make very difficult, probably impossible decisions about what is and what is not generated by ChatGPT, we can put up parameters about how we would like to see it used in the class. The goal is, the students will learn real skills, and hopefully take those forward with them as they enter the workplace.”

Katzenstein thinks of AI as transformative rather than marginal change, he said. “Students will have to find their way in this world while writing, as a basic cultural technology, will fundamentally change.”
