Thesis and Purpose Statements

Use the guidelines below to learn the differences between thesis and purpose statements.

In the first stages of writing, thesis or purpose statements are usually rough or ill-formed and are useful primarily as planning tools.

A thesis statement or purpose statement will emerge as you think and write about a topic. The statement can be restricted or clarified and eventually worked into an introduction.

As you revise your paper, try to phrase your thesis or purpose statement in a precise way so that it matches the content and organization of your paper.

Thesis statements

A thesis statement is a sentence that makes an assertion about a topic and predicts how the topic will be developed. It does not simply announce a topic: it says something about the topic.

Good: X has made a significant impact on the teenage population due to its . . . Bad: In this paper, I will discuss X.

A thesis statement makes a promise to the reader about the scope, purpose, and direction of the paper. It summarizes the conclusions that the writer has reached about the topic.

A thesis statement is generally located near the end of the introduction. Sometimes in a long paper, the thesis will be expressed in several sentences or an entire paragraph.

A thesis statement is focused and specific enough to be proven within the boundaries of the paper. Key words (nouns and verbs) should be specific, accurate, and indicative of the range of research, thrust of the argument or analysis, and the organization of supporting information.

Purpose statements

A purpose statement announces the purpose, scope, and direction of the paper. It tells the reader what to expect in a paper and what the specific focus will be.

Common beginnings include:

“This paper examines . . .,” “The aim of this paper is to . . .,” and “The purpose of this essay is to . . .”

A purpose statement makes a promise to the reader about the development of the argument but does not preview the particular conclusions that the writer has drawn.

A purpose statement usually appears toward the end of the introduction. The purpose statement may be expressed in several sentences or even an entire paragraph.

A purpose statement is specific enough to satisfy the requirements of the assignment. Purpose statements are common in research papers in some academic disciplines, while in other disciplines they are considered too blunt or direct. If you are unsure about using a purpose statement, ask your instructor.

This paper will examine the ecological destruction of the Sahel preceding the drought and the causes of this disintegration of the land. The focus will be on the economic, political, and social relationships which brought about the environmental problems in the Sahel.

Sample purpose and thesis statements

The following example combines a purpose statement and a thesis statement (bold).

The goal of this paper is to examine the effects of Chile’s agrarian reform on the lives of rural peasants. The nature of the topic dictates the use of both a chronological and a comparative analysis of peasant lives at various points during the reform period. . . The Chilean reform example provides evidence that land distribution is an essential component of both the improvement of peasant conditions and the development of a democratic society. More extensive and enduring reforms would likely have allowed Chile the opportunity to further expand these horizons.

Difference Between Thesis and Purpose Statements

' src=

As you select your topic and plan your research, you’ll need to think about your point of focus. Your instructor may ask you to write a thesis statement or a purpose statement. Sometimes you will have both in the same paper. No matter what type of style you use – MLA, APA or Chicago , – you’ll need to include thesis or purpose statements.

How to Use Thesis or Purpose Statements

After you select your topic , you’ll need to determine the point of your paper. Are you trying to persuade your reader towards a certain conclusion? Are you comparing and contrasting other people’s arguments?

During the first part of developing your research paper or essay, you can create a rough draft of a thesis or purpose statement to drive your research. As you work through your paper, you’ll refine these statements.

Although your thesis or purpose statement is included in the introduction , it’s often advised to write your introduction last. That way, you’ve presented your research to its conclusion. Then, you’ll have a clear idea of your introduction.

Thesis Statements

Typically, your thesis statement will be placed at or near the end of your introduction. It can be one or two sentences, or even up to a paragraph long. However, don’t make it so long that the reader has difficulty understanding it. Your thesis statement is your argument or the answer to a question or problem. The thesis statement provides the scope, purpose and direction of your paper. It is specific and focused.

Focused interviews and examination of published research indicate that college students report increased satisfaction in attending classes with cultural diversity. Community colleges that embrace cultural diversity have happier students overall.

Purpose Statements

Purpose statements are used to let the reader know what the paper is about and what to expect from it. You can tell a purpose statement by the way it’s written. A purpose statement, unlike a thesis statement, doesn’t discuss any conclusions. It must also be concise and specific. For example, the sentence can begin with phrases such as:

  • The purpose of this paper is to….
  • This essay examines…..
  • In this paper, I will describe…..

This essay examines cultural diversity in community colleges. The focus will be on how cultural diversity affects students’ daily lives.

Combining a Purpose and Thesis Statement

Instructor Discussing Difference Between Thesis and Purpose Statements

You may include both a purpose and thesis statement. Again, check with your instructor. Teachers will provide specific instructions for you to follow in completing your assignment.

This essay examines cultural diversity in community colleges. The focus will be on how cultural diversity affects students’ daily lives. Focused interviews and examination of published research indicate that college students report increased satisfaction in attending classes with cultural diversity. Community colleges that embrace cultural diversity have happier students overall.

Tying It All Together

The thesis or purpose statement needs to match what you state in your essay. Preparing an outline before you begin your paper helps you stay on track. Teachers will often assign an outline for that reason. However, even if it’s not part of your assignment, creating an outline is an effective way to organize your paper.

Your introduction and conclusion should tie together. The ideas you presented in your introduction will be backed up by the research in your paper, and your conclusion will bring it all together.

Generally, you’ll provide either a thesis statement or a purpose statement. As you enter college writing classes, you will need to understand how to write a good thesis statement. Your instructor will provide an assignment rubric, which you should follow at all times. The school or public librarian can guide you to excellent resources on writing essays and research papers.

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.

What Is a Thesis? | Ultimate Guide & Examples

Published on September 14, 2022 by Tegan George . Revised on April 16, 2024.

A thesis is a type of research paper based on your original research. It is usually submitted as the final step of a master’s program or a capstone to a bachelor’s degree.

Writing a thesis can be a daunting experience. Other than a dissertation , it is one of the longest pieces of writing students typically complete. It relies on your ability to conduct research from start to finish: choosing a relevant topic , crafting a proposal , designing your research , collecting data , developing a robust analysis, drawing strong conclusions , and writing concisely .

You may have heard the word thesis as a standalone term or as a component of academic writing called a thesis statement . Keep in mind that these are two very different things.

  • A thesis statement is a very common component of an essay, particularly in the humanities. It usually comprises 1 or 2 sentences in the introduction of your essay , and should clearly and concisely summarize the central points of your academic essay .
  • A thesis is a long-form piece of academic writing, often taking more than a full semester to complete. It is generally a degree requirement for Master’s programs, and is also sometimes required to complete a bachelor’s degree in liberal arts colleges.
  • In the US, a dissertation is generally written as a final step toward obtaining a PhD.
  • In other countries (particularly the UK), a dissertation is generally written at the bachelor’s or master’s level.

Prevent plagiarism. Run a free check.

The final structure of your thesis depends on a variety of components, such as:

  • Your discipline
  • Your theoretical approach

Humanities theses are often structured more like a longer-form essay . Just like in an essay, you build an argument to support a central thesis.

In both hard and social sciences, theses typically include an introduction , literature review , methodology section ,  results section , discussion section , and conclusion section . These are each presented in their own dedicated section or chapter. In some cases, you might want to add an appendix .

Thesis examples

We’ve compiled a short list of thesis examples to help you get started.

  • Example thesis #1:   “Abolition, Africans, and Abstraction: the Influence of the ‘Noble Savage’ on British and French Antislavery Thought, 1787-1807” by Suchait Kahlon.
  • Example thesis #2: “’A Starving Man Helping Another Starving Man’: UNRRA, India, and the Genesis of Global Relief, 1943-1947″ by Julian Saint Reiman.

The very first page of your thesis contains all necessary identifying information, including:

  • Your full title
  • Your full name
  • Your department
  • Your institution and degree program
  • Your submission date.

Sometimes the title page also includes your student ID, the name of your supervisor, or the university’s logo. Check out your university’s guidelines if you’re not sure.

Read more about title pages

The acknowledgements section is usually optional. Its main point is to allow you to thank everyone who helped you in your thesis journey, such as supervisors, friends, or family. You can also choose to write a preface , but it’s typically one or the other, not both.

Read more about acknowledgements Read more about prefaces

An abstract is a short summary of your thesis. Usually a maximum of 300 words long, it’s should include brief descriptions of your research objectives , methods, results, and conclusions. Though it may seem short, it introduces your work to your audience, serving as a first impression of your thesis.

Read more about abstracts

A table of contents lists all of your sections, plus their corresponding page numbers and subheadings if you have them. This helps your reader seamlessly navigate your document.

Your table of contents should include all the major parts of your thesis. In particular, don’t forget the the appendices. If you used heading styles, it’s easy to generate an automatic table Microsoft Word.

Read more about tables of contents

While not mandatory, if you used a lot of tables and/or figures, it’s nice to include a list of them to help guide your reader. It’s also easy to generate one of these in Word: just use the “Insert Caption” feature.

Read more about lists of figures and tables

If you have used a lot of industry- or field-specific abbreviations in your thesis, you should include them in an alphabetized list of abbreviations . This way, your readers can easily look up any meanings they aren’t familiar with.

Read more about lists of abbreviations

Relatedly, if you find yourself using a lot of very specialized or field-specific terms that may not be familiar to your reader, consider including a glossary . Alphabetize the terms you want to include with a brief definition.

Read more about glossaries

An introduction sets up the topic, purpose, and relevance of your thesis, as well as expectations for your reader. This should:

  • Ground your research topic , sharing any background information your reader may need
  • Define the scope of your work
  • Introduce any existing research on your topic, situating your work within a broader problem or debate
  • State your research question(s)
  • Outline (briefly) how the remainder of your work will proceed

In other words, your introduction should clearly and concisely show your reader the “what, why, and how” of your research.

Read more about introductions

A literature review helps you gain a robust understanding of any extant academic work on your topic, encompassing:

  • Selecting relevant sources
  • Determining the credibility of your sources
  • Critically evaluating each of your sources
  • Drawing connections between sources, including any themes, patterns, conflicts, or gaps

A literature review is not merely a summary of existing work. Rather, your literature review should ultimately lead to a clear justification for your own research, perhaps via:

  • Addressing a gap in the literature
  • Building on existing knowledge to draw new conclusions
  • Exploring a new theoretical or methodological approach
  • Introducing a new solution to an unresolved problem
  • Definitively advocating for one side of a theoretical debate

Read more about literature reviews

Theoretical framework

Your literature review can often form the basis for your theoretical framework, but these are not the same thing. A theoretical framework defines and analyzes the concepts and theories that your research hinges on.

Read more about theoretical frameworks

Your methodology chapter shows your reader how you conducted your research. It should be written clearly and methodically, easily allowing your reader to critically assess the credibility of your argument. Furthermore, your methods section should convince your reader that your method was the best way to answer your research question.

A methodology section should generally include:

  • Your overall approach ( quantitative vs. qualitative )
  • Your research methods (e.g., a longitudinal study )
  • Your data collection methods (e.g., interviews or a controlled experiment
  • Any tools or materials you used (e.g., computer software)
  • The data analysis methods you chose (e.g., statistical analysis , discourse analysis )
  • A strong, but not defensive justification of your methods

Read more about methodology sections

Your results section should highlight what your methodology discovered. These two sections work in tandem, but shouldn’t repeat each other. While your results section can include hypotheses or themes, don’t include any speculation or new arguments here.

Your results section should:

  • State each (relevant) result with any (relevant) descriptive statistics (e.g., mean , standard deviation ) and inferential statistics (e.g., test statistics , p values )
  • Explain how each result relates to the research question
  • Determine whether the hypothesis was supported

Additional data (like raw numbers or interview transcripts ) can be included as an appendix . You can include tables and figures, but only if they help the reader better understand your results.

Read more about results sections

Your discussion section is where you can interpret your results in detail. Did they meet your expectations? How well do they fit within the framework that you built? You can refer back to any relevant source material to situate your results within your field, but leave most of that analysis in your literature review.

For any unexpected results, offer explanations or alternative interpretations of your data.

Read more about discussion sections

Your thesis conclusion should concisely answer your main research question. It should leave your reader with an ultra-clear understanding of your central argument, and emphasize what your research specifically has contributed to your field.

Why does your research matter? What recommendations for future research do you have? Lastly, wrap up your work with any concluding remarks.

Read more about conclusions

In order to avoid plagiarism , don’t forget to include a full reference list at the end of your thesis, citing the sources that you used. Choose one citation style and follow it consistently throughout your thesis, taking note of the formatting requirements of each style.

Which style you choose is often set by your department or your field, but common styles include MLA , Chicago , and APA.

Create APA citations Create MLA citations

In order to stay clear and concise, your thesis should include the most essential information needed to answer your research question. However, chances are you have many contributing documents, like interview transcripts or survey questions . These can be added as appendices , to save space in the main body.

Read more about appendices

Once you’re done writing, the next part of your editing process begins. Leave plenty of time for proofreading and editing prior to submission. Nothing looks worse than grammar mistakes or sloppy spelling errors!

Consider using a professional thesis editing service or grammar checker to make sure your final project is perfect.

Once you’ve submitted your final product, it’s common practice to have a thesis defense, an oral component of your finished work. This is scheduled by your advisor or committee, and usually entails a presentation and Q&A session.

After your defense , your committee will meet to determine if you deserve any departmental honors or accolades. However, keep in mind that defenses are usually just a formality. If there are any serious issues with your work, these should be resolved with your advisor way before a defense.

The conclusion of your thesis or dissertation shouldn’t take up more than 5–7% of your overall word count.

If you only used a few abbreviations in your thesis or dissertation , you don’t necessarily need to include a list of abbreviations .

If your abbreviations are numerous, or if you think they won’t be known to your audience, it’s never a bad idea to add one. They can also improve readability, minimizing confusion about abbreviations unfamiliar to your reader.

When you mention different chapters within your text, it’s considered best to use Roman numerals for most citation styles. However, the most important thing here is to remain consistent whenever using numbers in your dissertation .

A thesis or dissertation outline is one of the most critical first steps in your writing process. It helps you to lay out and organize your ideas and can provide you with a roadmap for deciding what kind of research you’d like to undertake.

Generally, an outline contains information on the different sections included in your thesis or dissertation , such as:

  • Your anticipated title
  • Your abstract
  • Your chapters (sometimes subdivided into further topics like literature review , research methods , avenues for future research, etc.)

A thesis is typically written by students finishing up a bachelor’s or Master’s degree. Some educational institutions, particularly in the liberal arts, have mandatory theses, but they are often not mandatory to graduate from bachelor’s degrees. It is more common for a thesis to be a graduation requirement from a Master’s degree.

Even if not mandatory, you may want to consider writing a thesis if you:

  • Plan to attend graduate school soon
  • Have a particular topic you’d like to study more in-depth
  • Are considering a career in research
  • Would like a capstone experience to tie up your academic experience

Thesis vs. Topic Sentence

What's the difference.

A thesis statement and a topic sentence are both essential components of academic writing, but they serve different purposes. A thesis statement is a concise and arguable claim that presents the main idea or argument of an essay or research paper. It provides a roadmap for the entire piece of writing and guides the reader on what to expect. On the other hand, a topic sentence is a statement that introduces the main idea of a paragraph. It acts as a mini-thesis within the larger context of the thesis statement, focusing on a specific aspect or supporting point. While a thesis statement is typically found at the end of an introduction, a topic sentence is usually the first sentence of a paragraph.

AttributeThesisTopic Sentence
DefinitionA statement or theory that is put forward as a premise to be maintained or proved.A sentence that expresses the main idea or focus of a paragraph or essay.
PlacementUsually found in the introduction or conclusion of an essay.Typically appears at the beginning of a paragraph.
FunctionProvides a clear and concise summary of the main argument or point of view in an essay.Introduces the main idea of a paragraph and sets the tone for the following sentences.
ScopeEncompasses the entire essay or research paper.Focuses on a specific point within a paragraph.
LengthUsually consists of one or two sentences.Varies in length but is typically shorter than a thesis statement.
ContentStates the main argument or claim and provides a roadmap for the essay.Introduces the main idea of the paragraph and supports the overall thesis statement.

Further Detail

Introduction.

When it comes to academic writing, two essential components that play a crucial role in structuring an essay or research paper are the thesis statement and the topic sentence. Both the thesis statement and the topic sentence serve as guiding principles for the entire piece of writing, providing a clear focus and direction. While they share similarities in their purpose, they also have distinct attributes that set them apart. In this article, we will explore the characteristics of both the thesis statement and the topic sentence, highlighting their importance and differences.

Thesis Statement

A thesis statement is a concise and declarative sentence that presents the main argument or claim of an essay or research paper. It is typically found in the introductory paragraph and sets the tone for the entire piece of writing. The thesis statement is often considered the backbone of the paper, as it provides a roadmap for the reader and guides the writer's thought process.

One of the key attributes of a thesis statement is its specificity. It should clearly state the main point or argument of the paper, leaving no room for ambiguity. A well-crafted thesis statement is focused and precise, allowing the reader to understand the writer's stance on the topic from the very beginning.

Furthermore, a thesis statement should be arguable. It should present a claim that can be supported or refuted through evidence and logical reasoning. This attribute distinguishes a thesis statement from a mere statement of fact. By presenting an arguable claim, the writer invites the reader to engage with the topic and consider different perspectives.

In addition, a thesis statement should be concise and to the point. It should capture the essence of the writer's argument without unnecessary elaboration. This brevity ensures that the thesis statement remains clear and impactful, avoiding confusion or ambiguity.

Lastly, a thesis statement should be placed at the end of the introductory paragraph. This positioning allows it to serve as a transition between the introduction and the body paragraphs, providing a smooth flow of ideas and setting the stage for the subsequent discussion.

Topic Sentence

Similar to a thesis statement, a topic sentence plays a vital role in structuring a paragraph within an essay or research paper. While a thesis statement encompasses the entire paper, a topic sentence focuses on a specific paragraph or section. It serves as a mini-thesis, summarizing the main idea of the paragraph and connecting it to the overall argument.

One of the primary attributes of a topic sentence is its clarity. It should clearly state the main point of the paragraph, allowing the reader to understand its purpose and relevance. A well-crafted topic sentence provides a concise preview of the information that will be discussed in the paragraph, guiding the reader through the writer's thought process.

Furthermore, a topic sentence should be unified. It should address only one main idea or argument, avoiding the inclusion of unrelated or extraneous information. This attribute ensures that the paragraph remains focused and coherent, enhancing the overall clarity and effectiveness of the writing.

In addition, a topic sentence should be placed at the beginning of the paragraph. This positioning allows it to serve as a clear transition from the previous paragraph and provides a logical flow of ideas throughout the essay or research paper. By starting with a strong topic sentence, the writer sets the stage for the subsequent discussion and helps the reader navigate through the content smoothly.

Lastly, a topic sentence should be supported by evidence and examples. It should not only present the main idea but also provide sufficient information to validate or illustrate the point being made. By including supporting details, the writer strengthens the argument and enhances the overall persuasiveness of the paragraph.

In conclusion, both the thesis statement and the topic sentence are essential components of academic writing that provide structure and coherence to essays and research papers. While the thesis statement encompasses the entire paper and presents the main argument, the topic sentence focuses on individual paragraphs and summarizes their main ideas. Both the thesis statement and the topic sentence should be clear, specific, and supported by evidence. The thesis statement is placed in the introductory paragraph, while the topic sentence starts each paragraph. By understanding the attributes of both the thesis statement and the topic sentence, writers can effectively convey their ideas and engage readers in their writing.

Thesis/Purpose Statement

Probably the most daunting task for any writer is to generate an effective thesis statement.  In college, academic writing follows a specific pattern— after a brief opening, you state your position in one clear sentence. Whether your essay is explanatory or argumentative, a strong thesis statement will provide the map, guiding the entire essay. Confusion arises, however, over the difference between a purpose statement and a thesis.

What is the function of a purpose statement?

  • It gives the paper a focus: scope and direction.
  • It foreshadows the development of the argument

Used in many of the sciences for research proposals, in some disciplines, a purpose statement is too blunt or direct, so check with your instructor about using a purpose statement.

Sample purpose statement This paper will examine the ecological damage caused by Katrina on the Gulf Coast. The focus will be on the economic, political and social relationships effected by the environmental problems.

What is the function of a thesis statement? A thesis statement:

  • Gives the writer’s declaration of the purpose of the paper.
  • Makes an assertion directly answering the question the paper asks.
  • Offers a provable claim that reasonable people could argue.
  • Provides a map of the arrangement of ideas presented in the essay.

(Note that the thesis statement is more complex than the purpose statement)

Sample thesis statement        The ecological damage produced by Katrina on the Gulf Coast was caused by the political and social environment of the region.

What are the characteristics of a good thesis statement?

  • It answers a specific question.
  • It is narrow or broad enough to be covered within the assignment parameters.
  • It focuses on one main idea.
  • It is controversial enough that a reasonable person could disagree.

How do I generate a good thesis statement? After you have completed your research for evidence, you will need to analyze the material to find the possible connections— both similarities and contrasts. Once you have analyzed your evidence, you will have a main idea or a working thesis. Think of the process of creating a thesis like a funnel, beginning with a general subject, narrowed by the purpose, and ending with a specific assertion, claim, or thesis.

How do I generate a thesis if the topic is assigned? Any assignment can be narrowed down to a single question. Your first task is to select the focal question that your essay will answer. If the assignment is a request for information, such as “Write a report on the benefits of expanding the Marina District in Downtown Toledo,” turn the request into a question— “What are the benefits of building the Marina District in Downtown Toledo?” After you have established the focal question, compose a one- to- two-sentence response based on your educated opinion.

Q: What are the benefits of the Marina District in Toledo?

A: The potential benefits of the development of the Marina District are….

How do I generate a thesis if the topic is not assigned?

Even if your instructor has not posed a specific question, you will need to create a question about the issue you plan to investigate. It is best if you first establish your subject; next consider the purpose of the essay. From this point you should be able to ask a question about the topic to then state a position or thesis.

Brainstorm the topic What are your concerns? What concerns are facing your field of study? For example, you are in construction and you are concerned with the slow recovery in New Orleans after Katrina. You begin the thought process like this:

Construction reform.

This is not a thesis; it is a fragment. This is a general subject from which you could take your paper in many directions. Perhaps from your research you have found that there were oversights in the codes for homes constructed in hurricane and flood zones. While everyone will agree that rebuilding flimsy homes is a bad idea, narrowing your topic to who should make the reform and what specific types are needed will assert your position.

Because a majority of the damage caused by Katrina was due to inadequate construction, the federal government needs to establish more stringent building codes before financing reconstruction.

Test your thesis

  • Does it take a stand and capture the subject?
  • Does it invite a discussion or can a simple statement respond it to?
  • Is it specific to your paper?
  • Is your claim significant?
  • Are the words and phrases a unified by a single idea?

Test the sample thesis Because a majority of the damage caused by Katrina was due to inadequate construction, the federal government needs to establish more stringent building codes before financing reconstruction.

  • Does it take a stand? Yes, the damage was due to inadequate construction and the federal government needs to step in.
  • Does it invite discussion? Yes, some reasonable people may feel that it is not the government’s responsibility to enforce codes and that no building could withstand the force of Katrina.
  • Is the thesis specific? Yes, it focuses on the aftermath of one storm and the steps to be taken before more federal funds should be used.
  • Is the claim significant? Yes, rebuilding still needs to take place.
  • Are the words focused on a single idea? Yes, not all issues are being addressed, just one aspect of a condition for rebuilding. Yet the thesis is still broad enough to allow the paper to explore examples of the types of destruction, building codes, and financial needs facing those devastated by Katrina.

Developing a Strong, Clear Thesis Statement

provided by University of Minnesota

Have you ever known a person who was not very good at telling stories? You probably had trouble following his train of thought as he jumped around from point to point, either being too brief in places that needed further explanation or providing too many details on a meaningless element. Maybe he told the end of the story first, then moved to the beginning and later added details to the middle. His ideas were probably scattered, and the story did not flow very well. When the story was over, you probably had many questions.

Just as a personal anecdote can be a disorganized mess, an essay can fall into the same trap of being out of order and confusing. That is why writers need a thesis statement to provide a specific focus for their essay and to organize what they are about to discuss in the body.

Just like a topic sentence summarizes a single paragraph, the thesis statement summarizes an entire essay. It tells the reader the point you want to make in your essay, while the essay itself supports that point. It is like a signpost that signals the essay’s destination. You should form your thesis before you begin to organize an essay, but you may find that it needs revision as the essay develops.

Elements of a Thesis Statement

For every essay you write, you must focus on a central idea. This idea stems from a topic you have chosen or been assigned or from a question your teacher has asked. It is not enough merely to discuss a general topic or simply answer a question with a yes or no. You have to form a specific opinion, and then articulate that into a  controlling idea —the main idea upon which you build your thesis.

Remember that a thesis is not the topic itself, but rather your interpretation of the question or subject. For whatever topic your professor gives you, you must ask yourself, “What do I want to say about it?” Asking and then answering this question is vital to forming a thesis that is precise, forceful and confident.

A thesis is one sentence long and appears toward the end of your introduction. It is specific and focuses on one to three points of a single idea—points that are able to be demonstrated in the body. It forecasts the content of the essay and suggests how you will organize your information. Remember that a thesis statement does not summarize an issue but rather dissects it.

A Strong Thesis Statement

A strong thesis statement contains the following qualities.

strong thesis statement .  A thesis statement must concentrate on a specific area of a general topic. As you may recall, the creation of a thesis statement begins when you choose a broad subject and then narrow down its parts until you pinpoint a specific aspect of that topic. For example, health care is a broad topic, but a proper thesis statement would focus on a specific area of that topic, such as options for individuals without health care coverage.

Precision.  A strong thesis statement must be precise enough to allow for a coherent argument and to remain focused on the topic. If the specific topic is options for individuals without health care coverage, then your precise thesis statement must make an exact claim about it, such as that limited options exist for those who are uninsured by their employers. You must further pinpoint what you are going to discuss regarding these limited effects, such as whom they affect and what the cause is.

Ability to be argued.  A thesis statement must present a relevant and specific argument. A factual statement often is not considered arguable. Be sure your thesis statement contains a point of view that can be supported with evidence.

Ability to be demonstrated.  For any claim you make in your thesis, you must be able to provide reasons and examples for your opinion. You can rely on personal observations in order to do this, or you can consult outside sources to demonstrate that what you assert is valid. A worthy argument is backed by examples and details.

Forcefulness.  A thesis statement that is forceful shows readers that you are, in fact, making an argument. The tone is assertive and takes a stance that others might oppose.

Confidence.  In addition to using force in your thesis statement, you must also use confidence in your claim. Phrases such as  I feel  or  I believe  actually weaken the readers’ sense of your confidence because these phrases imply that you are the only person who feels the way you do. In other words, your stance has insufficient backing. Taking an authoritative stance on the matter persuades your readers to have faith in your argument and open their minds to what you have to say.

Even in a personal essay that allows the use of first person, your thesis should not contain phrases such as  in my opinion  or  I believe . These statements reduce your credibility and weaken your argument. Your opinion is more convincing when you use a firm attitude.

Examples of Appropriate Thesis Statements

Each of the following thesis statements meets several of the following requirements:

  • Specificity
  • Ability to be argued
  • Ability to be demonstrated
  • Forcefulness
  • The societal and personal struggles of Troy Maxon in the play Fences symbolize the challenge of black males who lived through segregation and integration in the United States.
  • Closing all American borders for a period of five years is one solution that will tackle illegal immigration.
  • Shakespeare’s use of dramatic irony in Romeo and Juliet spoils the outcome for the audience and weakens the plot.
  • J. D. Salinger’s character in Catcher in the Rye, Holden Caulfield, is a confused rebel who voices his disgust with phonies, yet in an effort to protect himself, he acts like a phony on many occasions.
  • Compared to an absolute divorce, no-fault divorce is less expensive, promotes fairer settlements, and reflects a more realistic view of the causes for marital breakdown.
  • Exposing children from an early age to the dangers of drug abuse is a sure method of preventing future drug addicts. In today’s crumbling job market, a high school diploma is not significant enough education to land a stable, lucrative job.

You can find thesis statements in many places, such as in the news; in the opinions of friends, coworkers or teachers; and even in songs you hear on the radio. Become aware of thesis statements in everyday life by paying attention to people’s opinions and their reasons for those opinions. Pay attention to your own everyday thesis statements as well, as these can become material for future essays.

Now that you have read about the contents of a good thesis statement and have seen examples, take a look at the pitfalls to avoid when composing your own thesis:

A thesis is weak when it is simply a declaration of your subject or a description of what you will discuss in your essay.

Weak thesis statement:  My paper will explain why imagination is more important than knowledge.

A thesis is weak when it makes an unreasonable or outrageous claim or insults the opposing side.

Weak thesis statement:  Religious radicals across America are trying to legislate their Puritanical beliefs by banning required high school books.

A thesis is weak when it contains an obvious fact or something that no one can disagree with or provides a dead end.

Weak thesis statement:  Advertising companies use sex to sell their products.

A thesis is weak when the statement is too broad.

Weak thesis statement:  The life of Abraham Lincoln was long and challenging.

Writing at Work

Often in your career, you will need to ask your boss for something through an e-mail. Just as a thesis statement organizes an essay, it can also organize your e-mail request. While your e-mail will be shorter than an essay, using a thesis statement in your first paragraph quickly lets your boss know what you are asking for, why it is necessary, and what the benefits are. In short body paragraphs, you can provide the essential information needed to expand upon your request.

Thesis Statement Revision

Your thesis will probably change as you write, so you will need to modify it to reflect exactly what you have discussed in your essay. Remember  that your thesis statement begins as a  working thesis statement , an indefinite statement that you make about your topic early in the writing process for the purpose of planning and guiding your writing.

Working thesis statements often become stronger as you gather information and form new opinions and reasons for those opinions. Revision helps you strengthen your thesis so that it matches what you have expressed in the body of the paper.

The best way to revise your thesis statement is to ask questions about it and then examine the answers to those questions. By challenging your own ideas and forming definite reasons for those ideas, you grow closer to a more precise point of view, which you can then incorporate into your thesis statement.

Ways to Revise Your Thesis

You can cut down on irrelevant aspects and revise your thesis by taking the following steps:

1. Pinpoint and replace all nonspecific words, such as  people ,  everything ,  society , or  life , with more precise words in order to reduce any vagueness.

Working thesis:  Young people have to work hard to succeed in life.

Revised thesis:  Recent college graduates must have discipline and persistence in order to find and maintain a stable job in which they can use and be appreciated for their talents.

The revised thesis makes a more specific statement about success and what it means to work hard. The original includes too broad a range of people and does not define exactly what success entails. By replacing those general words like  people  and  work hard , the writer can better focus his or her research and gain more direction in his or her writing.

2. Clarify ideas that need explanation by asking yourself questions that narrow your thesis.

Working thesis:  The welfare system is a joke.

Revised thesis:  The welfare system keeps a socioeconomic class from gaining employment by alluring members of that class with unearned income, instead of programs to improve their education and skill sets.

A joke  means many things to many people. Readers bring all sorts of backgrounds and perspectives to the reading process and would need clarification for a word so vague. This expression may also be too informal for the selected audience. By asking questions, the writer can devise a more precise and appropriate explanation for  joke . The writer should ask himself or herself questions similar to the 5WH questions. By incorporating the answers to these questions into a thesis statement, the writer more accurately defines his or her stance, which will better guide the writing of the essay.

3. Replace any  linking verbs  with action verbs. Linking verbs are forms of the verb  to be , a verb that simply states that a situation exists.

Working thesis:  Kansas City schoolteachers are not paid enough.

Revised thesis:  The Kansas City legislature cannot afford to pay its educators, resulting in job cuts and resignations in a district that sorely needs highly qualified and dedicated teachers.

The linking verb in this working thesis statement is the word  are . Linking verbs often make thesis statements weak because they do not express action. Rather, they connect words and phrases to the second half of the sentence. Readers might wonder, “Why are they not paid enough?” But this statement does not compel them to ask many more questions. The writer should ask himself or herself questions in order to replace the linking verb with an action verb, thus forming a stronger thesis statement, one that takes a more definitive stance on the issue:

  • Who is not paying the teachers enough?
  • What is considered “enough”?
  • What is the problem?
  • What are the results

4. Omit any general claims that are hard to support.

Working thesis:  Today’s teenage girls are too sexualized.

Revised thesis:  Teenage girls who are captivated by the sexual images on MTV are conditioned to believe that a woman’s worth depends on her sensuality, a feeling that harms their self-esteem and behavior.

It is true that some young women in today’s society are more sexualized than in the past, but that is not true for all girls. Many girls have strict parents, dress appropriately, and do not engage in sexual activity while in middle school and high school. The writer of this thesis should ask the following questions:

  • Which teenage girls?
  • What constitutes “too” sexualized?
  • Why are they behaving that way?
  • Where does this behavior show up?
  • What are the repercussions?

In your career you may have to write a project proposal that focuses on a particular problem in your company, such as reinforcing the tardiness policy. The proposal would aim to fix the problem; using a thesis statement would clearly state the boundaries of the problem and tell the goals of the project. After writing the proposal, you may find that the thesis needs revision to reflect exactly what is expressed in the body. Using the techniques from this chapter would apply to revising that thesis.

What is a thesis?

A thesis is

  • an academic body of work
  • a writer’s, speaker’s, or knowledge worker’s . . . main reason for communicating ; their purpose .

Related Concepts: Organizational Schema; Professional Writing Prose Style

Note: Some people consider thesis and purpose to be synonymous terms. Others view purpose to be a broader classification of discourse and thesis to be a more specific message or argument.

A writer’s thesis is the writer’s north star.

Writer’s, speaker’s, or knowledge worker’s . . . need to know their purpose , their reason for writing, in order to know how they need to compose their texts or submit those texts to their intended audiences .

A thesis may be expressed as

  • an argumentative theses (Dietrich)
  • an organizational theses
  • a research question

While writers need to know what their purpose is for communicating in order to communicate clearly , concisely , and in a unified manner, they do not necessarily need to explicitly state their theses . In fact, there are some rhetorical circumstances when the tone and voice might be better served by leaving the context and purpose unsaid, implied, tacit.

Thesis Statements are commonplace in Workplace contexts. It is commonplace–especially in workplace writing–for writers, speakers, knowledge workers . . . to explicitly state their thesis in the first or second sentence of their texts. This sort of approach is sometimes called a Direct Style as opposed to an Indirect Style , or a Deductive Approach as opposed to an Inductive Approach .

Examples of genres of discourse that emploay a direct style include business correspondence, executive abstracts, abstracts, executive summaries, and introductions to workplace writing.

However, there are occasions when it’s rhetorically most strategic for a writer, speaker, knowledge worker . . . to view the context to be so routine that it goes without saying between the writer and the reader, the speaker and the audience.

What are the functions of a thesis?

The thesis functions in several important ways:

  • It informs the reader of the paper’s direction

The thesis announces the direction of the paper’s conversation. Readers may find the paper’s position or argument more convincing if they know what to expect as they read.

  • It places boundaries on the paper’s content

The body of the paper provides support for the thesis. Only evidence and details that relate directly to the paper’s main ideas should fall within the boundary established by the thesis.

  • It determines how the content will be organized

The thesis summarizes the message or conclusion the reader is meant to understand and accept. A logical progression of these ideas and their supporting evidence helps shape the paper’s organization.

Speechwriting

8 Purpose and Thesis

Speechwriting Essentials

In this chapter . . .

As discussed in the chapter on Speaking Occasion , speechwriting begins with careful analysis of the speech occasion and its given circumstances, leading to the choice of an appropriate topic. As with essay writing, the early work of speechwriting follows familiar steps: brainstorming, research, pre-writing, thesis, and so on.

This chapter focuses on techniques that are unique to speechwriting. As a spoken form, speeches must be clear  about the purpose and main idea or “takeaway.” Planned redundancy means that you will be repeating these elements several times over during the speech.

Furthermore, finding purpose and thesis are essential whether you’re preparing an outline for extemporaneous delivery or a completely written manuscript for presentation. When you know your topic, your general and specific purpose, and your thesis or central idea, you have all the elements you need to write a speech that is focused, clear, and audience friendly.

Recognizing the General Purpose

Speeches have traditionally been grouped into one of three categories according to their primary purpose: 1) to inform, 2) to persuade, or 3) to inspire, honor, or entertain. These broad goals are commonly known as the  general purpose of a speech . Earlier, you learned about the actor’s tool of intention or objectives. The general purpose is like a super-objective; it defines the broadest goal of a speech. These three purposes are not necessarily exclusive to the others. A speech designed to be persuasive can also be informative and entertaining. However, a speech should have one primary goal. That is its general purpose.

Why is it helpful to talk about speeches in such broad terms? Being perfectly clear about what you want your speech to do or make happen for your audience will keep you focused. You can make a clearer distinction between whether you want your audience to leave your speech knowing more (to inform), or  ready to take action (to persuade), or feeling something (to inspire)

It’s okay to use synonyms for these broad categories. Here are some of them:

  • To inform could be to explain, to demonstrate, to describe, to teach.
  • To persuade could be to convince, to argue, to motivate, to prove.
  • To inspire might be to honor, or entertain, to celebrate, to mourn.

In summary, the first question you must ask yourself when starting to prepare a speech is, “Is the primary purpose of my speech to inform, to persuade, or to inspire?”

Articulating Specific Purpose

A specific purpose statement builds upon your general purpose and makes it specific (as the name suggests). For example, if you have been invited to give a speech about how to do something, your general purpose is “to inform.”  Choosing a topic appropriate to that general purpose, you decide to speak about how to protect a personal from cyberattacks. Now you are on your way to identifying a specific purpose.

A good specific purpose statement has three elements: goal, target audience, and content.

Goal (To + active word) for example: to inform, to explain, to convince, to honor
Audience my classmates, the members of my sorority, my coworkers
Content how to bake brownies, the history of EVs, Macs are better than PCs.

If you think about the above as a kind of recipe, then the first two “ingredients” — your goal and your audience — should be simple. Words describing the target audience should be as specific as possible. Instead of “my peers,” you could say, for example, “students in their senior year at my university.”

The third ingredient in this recipe is content, or what we call the topic of your speech. This is where things get a bit difficult. You want your content to be specific and something that you can express succinctly in a sentence. Here are some common problems that speakers make in defining the content, and the fix:

too broad “I’m going to talk about climate change.” Narrow down a specific topic appropriate to the general purpose. “To talk about” isn’t clear. A better topic here might be: “To persuade my audience to make five simple changes in their lifestyle that support the fight against climate change.”
combined topics “My speech is about recycling and the increased frequency of hurricanes due to climate change.” The word “and” in a description of content is a sure signal of a combined topic. Combined topics are too complex, and they muddy your focus. Choose one OR the other.
content doesn’t match the purpose “To inform my classmates about why they should support LGBTQ+ safe spaces on campus.”” Match the content to the general purpose. Do you see the word “should” here? That is a sure sign that the topic is persuasive, not informative. An informative speech on this topic would be “To inform my classmates about the LGBTQ+ safe spaces available on campus.”

Now you know the “recipe” for a specific purpose statement. It’s made up of  T o, plus an active W ord, a specific  A udience, and clearly stated  C ontent. Remember this formula: T + W + A + C.

A: for a group of new students

C: the term “plagiarism”

Here are some further examples a good specific purpose statement:

  • To explain to a group of first-year students how to join a school organization.
  • To persuade the members of the Greek society to take a spring break trip in Daytona Beach.
  • To motivate my classmates in English 101 to participate in a study abroad program.
  • To convince first-year students that they need at least seven hours of sleep per night to do well in their studies.
  • To inspire my Church community about the accomplishments of our pastor.

The General and Specific Purpose Statements are writing tools in the sense that they help you, as a speechwriter, clarify your ideas.

Creating a Thesis Statement

Once you are clear about your general purpose and specific purpose, you can turn your attention to crafting a thesis statement. A thesis is the central idea in an essay or a speech. In speechwriting, the thesis or central idea explains the message of the content. It’s the speech’s “takeaway.” A good thesis statement will also reveal and clarify the ideas or assertions you’ll be addressing in your speech (your main points). Consider this example:

General Purpose: To persuade. Specific Purpose: To motivate my classmates in English 101 to participate in a study abroad program. Thesis: A semester-long study abroad experience produces lifelong benefits by teaching you about another culture, developing your language skills, and enhancing your future career prospects.

The difference between a specific purpose statement and a thesis statement is clear in this example. The thesis provides the takeaway (the lifelong benefits of study abroad). It also points to the assertions that will be addressed in the speech. Like the specific purpose statement, the thesis statement is a writing tool. You’ll incorporate it into your speech, usually as part of the introduction and conclusion.

All good expository, rhetorical, and even narrative writing contains a thesis. Many students and even experienced writers struggle with formulating a thesis. We struggle when we attempt to “come up with something” before doing the necessary research and reflection. A thesis only becomes clear through the thinking and writing process. As you develop your speech content, keep asking yourself: What is important here? If the audience can remember only one thing about this topic, what do I want them to remember?

Example #2: General Purpose: To inform Specific Purpose: To demonstrate to my audience the correct method for cleaning a computer keyboard. Central Idea: Your computer keyboard needs regular cleaning to function well, and you can achieve that in four easy steps.
Example # 3 General Purpose: To Inform Specific Purpose: To describe how makeup is done for the TV show The Walking Dead . Central Idea: The wildly popular zombie show The Walking Dead achieves incredibly scary and believable makeup effects, and in the next few minutes I will tell you who does it, what they use, and how they do it.

Notice in the examples above that neither the specific purpose nor the central idea ever exceeds one sentence. If your central idea consists of more than one sentence, then you are probably including too much information.

Problems to Avoid

The first problem many students have in writing their specific purpose statement has already been mentioned: specific purpose statements sometimes try to cover far too much and are too broad. For example:

“To explain to my classmates the history of ballet.”

Aside from the fact that this subject may be difficult for everyone in your audience to relate to, it’s enough for a three-hour lecture, maybe even a whole course. You’ll probably find that your first attempt at a specific purpose statement will need refining. These examples are much more specific and much more manageable given the limited amount of time you’ll have.

  • To explain to my classmates how ballet came to be performed and studied in the U.S.
  • To explain to my classmates the difference between Russian and French ballet.
  • To explain to my classmates how ballet originated as an art form in the Renaissance.
  • To explain to my classmates the origin of the ballet dancers’ clothing.

The second problem happens when the “communication verb” in the specific purpose does not match the content; for example, persuasive content is paired with “to inform” or “to explain.” Can you find the errors in the following purpose statements?

  • To inform my audience why capital punishment is unconstitutional. (This is persuasive. It can’t be informative since it’s taking a side)
  • To persuade my audience about the three types of individual retirement accounts. (Even though the purpose statement says “persuade,” it isn’t persuading the audience of anything. It is informative.)
  • To inform my classmates that Universal Studios is a better theme park than Six Flags over Georgia. (This is clearly an opinion; hence it is a persuasive speech and not merely informative)

The third problem exists when the content part of the specific purpose statement has two parts. One specific purpose is enough. These examples cover two different topics.

  • To explain to my audience how to swing a golf club and choose the best golf shoes.
  • To persuade my classmates to be involved in the Special Olympics and vote to fund better classes for the intellectually disabled.

To fix this problem of combined or hybrid purposes, you’ll need to select one of the topics in these examples and speak on that one alone.

The fourth problem with both specific purpose and central idea statements is related to formatting. There are some general guidelines that need to be followed in terms of how you write out these elements of your speech:

  • Don’t write either statement as a question.
  • Always use complete sentences for central idea statements and infinitive phrases (beginning with “to”) for the specific purpose statement.
  • Use concrete language (“I admire Beyoncé for being a talented performer and businesswoman”) and avoid subjective or slang terms (“My speech is about why I think Beyoncé is the bomb”) or jargon and acronyms (“PLA is better than CBE for adult learners.”)

There are also problems to avoid in writing the central idea statement. As mentioned above, remember that:

  • The specific purpose and central idea statements are not the same thing, although they are related.
  • The central idea statement should be clear and not complicated or wordy; it should “stand out” to the audience. As you practice delivery, you should emphasize it with your voice.
  • The central idea statement should not be the first thing you say but should follow the steps of a good introduction as outlined in the next chapters.

You should be aware that all aspects of your speech are constantly going to change as you move toward the moment of giving your speech. The exact wording of your central idea may change, and you can experiment with different versions for effectiveness. However, your specific purpose statement should not change unless there is a good reason to do so. There are many aspects to consider in the seemingly simple task of writing a specific purpose statement and its companion, the central idea statement. Writing good ones at the beginning will save you some trouble later in the speech preparation process.

Dissertation vs Thesis: Understanding the Key Differences

Sumalatha G

Table of Contents

Undergraduate and graduate students often find themselves navigating the intricacies of higher education, including the requirement to complete a research project as part of their academic journey.

This can be a source of confusion, particularly when it comes to distinguishing between a dissertation and a thesis. While both terms are used interchangeably in some educational institutions, they actually have distinct meanings and purposes. Let's delve into the world of dissertations and theses, exploring their differences, purposes, and unique attributes.

Defining the Terms: Dissertation and Thesis

What is a dissertation.

A dissertation is a research project that marks the culmination of a doctoral program. It requires students to conduct original research and contribute new knowledge to their field of study. Dissertations are typically longer and more comprehensive than theses, as they delve deep into a specific topic, often spanning several chapters.

When embarking on a dissertation, students are expected to choose a research topic that is both relevant and original. This topic should contribute to the existing body of knowledge in their field and address a gap in current research. To accomplish this, students must thoroughly review the existing literature and identify areas that require further investigation.

What is a Thesis?

A thesis, on the other hand, is usually associated with a master's degree program. It is a research project that allows students to explore a particular topic in depth. Theses are generally shorter than dissertations, spanning fewer chapters. While they also require original research, the depth and scope may be narrower compared to a dissertation.

Similar to a dissertation, a thesis requires students to select a research topic and conduct a thorough literature review. However, due to the shorter length of a thesis, the literature review may not be as extensive as that of a dissertation. Nevertheless, it is still important for students to demonstrate a comprehensive understanding of the existing knowledge on their chosen topic.

Key Differences Between Dissertation and Thesis

Purpose and structure.

The primary difference between a dissertation and a thesis lies in their purpose and structure. A dissertation aims to contribute new knowledge to a specific field of study and is typically a more extensive and comprehensive project. It involves an in-depth exploration of a research problem or question, often requiring the collection and analysis of primary data. The structure of a dissertation usually includes multiple chapters, such as an introduction, literature review, methodology, results, discussion, and conclusion.

Furthermore, a dissertation often requires the student to engage in critical thinking, originality, and creativity to develop a unique contribution to the field. It may involve the development of new theories, models, or frameworks that can advance the understanding of a particular subject area.

Length and Depth of Research

Dissertations are known for their length and the depth of research they require. Doctoral candidates spend years conducting original research, analyzing data, and crafting comprehensive arguments. The research conducted for a dissertation is typically more extensive and rigorous compared to that of a thesis.

In addition, a dissertation often involves a thorough review of existing literature to establish a theoretical framework and identify research gaps. This review helps situate the research within the broader academic context and provides a foundation for the research design and methodology. The depth of research in a dissertation allows for a more comprehensive analysis and interpretation of the findings.

Degree Level and Requirements

Another key difference between dissertations and theses is the level of education for which they are typically required. Dissertations are a common requirement for doctoral degrees, such as Ph.D. programs, while theses are more commonly associated with master's degree programs. The specific requirements for each project may vary across institutions and academic disciplines.

Doctoral candidates are expected to demonstrate a high level of expertise and mastery in their field of study. They are often required to defend their dissertation orally in front of a committee of experts in the field. This defense allows for a rigorous examination of the research, ensuring its validity and contribution to the field.

On the other hand, theses for master's degrees are usually shorter in length and may not require the same level of originality and depth of research as a dissertation. However, they still require students to demonstrate their ability to critically analyze existing literature, conduct research, and present their findings in a coherent and scholarly manner.

Choosing Between a Dissertation and a Thesis

Factors to consider.

When deciding between a dissertation and a thesis, several factors should be taken into account. Firstly, consider your academic goals and the requirements of your degree program. If you aim to pursue a doctoral degree or a research career, a dissertation may be the most appropriate choice. However, if your goals are more focused on professional advancement or further specialization within your field, a thesis may suit your needs.

Understanding Your Academic Goals

Reflect on your academic interests and aspirations, as well as the amount of time and resources you are willing to invest in your research project. Each option comes with its own set of challenges and expectations, so it is important to choose the path that aligns with your academic and career goals.

The Process: From Proposal to Defense

The dissertation process.

The dissertation process involves multiple stages, starting with the development of a research proposal. Doctoral candidates must conduct a literature review, outline their research methodology, collect and analyze data, and present their findings in a comprehensive written document. The final step typically involves defending the dissertation orally, where candidates must respond to questions and critique from a committee of experts in the field.

The Thesis Process

The thesis process follows a similar trajectory but on a smaller scale. Students will still need to develop a research proposal, conduct a literature review, collect and analyze data, and present their findings in a written document. The defense process for a thesis may involve an oral presentation or an examination by a committee, depending on the institution's requirements.

The Role of Advisors in Dissertations and Theses

Guidance and support in the dissertation journey.

Dissertation advisors play a crucial role in guiding students through the research process. They provide valuable mentorship, offer insights into the field, and help refine research questions and methodologies. Advisor-advisee relationships are essential for the successful completion of a dissertation, as advisors provide ongoing feedback and support during the entire research journey.

Mentorship in the Thesis Process

Similarly, thesis advisors offer mentorship and guidance to students pursuing a master's degree. They help students refine their research topic, provide feedback on drafts, and ensure that the research project meets the required standards. Working closely with a knowledgeable advisor can significantly enhance a student's thesis experience and contribute to the overall success of the project.

Understanding the differences between dissertations and theses is essential for students embarking on their research journey. By considering their academic goals and evaluating the resources available, students can make an informed decision when choosing between a dissertation and a thesis. Additionally, the guidance and support provided by advisors throughout the process are invaluable and contribute to the successful completion of these significant research endeavors.

Effective introductions and thesis statements, make them want to continue reading.

Writing an effective introduction is an art form. The introduction is the first thing that your reader sees. It is what invests the reader in your paper, and it should make them want to continue reading. You want to be creative and unique early on in your introduction; here are some strategies to help catch your reader’s attention:

  • Tell a brief anecdote or story
  • As a series of short rhetorical questions
  • Use a powerful quotation
  • Refute a common belief
  • Cite a dramatic fact or statistic

Your introduction also needs to adequately explain the topic and organization of your paper.

Your  thesis statement  identifies the purpose of your paper. It also helps focus the reader on your central point. An effective thesis establishes a tone and a point of view for a given purpose and audience. Here are some important things to consider when constructing your thesis statement.

  • Don’t just make a factual statement – your thesis is your educated opinion on a topic.
  • Don’t write a highly opinionated statement that might offend your audience.
  • Don’t simply make an announcement (ex. “Tuition should be lowered” is a much better thesis than “My essay will discuss if tuition should be lowered”).
  • Don’t write a thesis that is too broad – be specific.

The thesis is often located in the middle or at the end of the introduction, but considerations about audience, purpose, and tone should always guide your decision about its placement.

Sometimes it’s helpful to wait to write the introduction until after you’ve written the essay’s body because, again, you want this to be one of the strongest parts of the paper.

Example of an introduction:

Innocent people murdered because of the hysteria of young girls! Many people believe that the young girls who accused citizens of Salem, Massachusetts of taking part in witchcraft were simply acting to punish their enemies. But recent evidence shows that the young girls may have been poisoned by a fungus called Ergot, which affects rye and wheat. The general public needs to learn about this possible cause for the hysteria that occurred in Salem so that society can better understand what happened in the past, how this event may change present opinion, and how the future might be changed by learning this new information.

Thesis Statements vs. Main Ideas

The thesis statement is a one-sentence statement that expresses the main idea of the essay. The thesis statement is an arguable statement that communicates the author's stance on a topic to the reader. In order to better understand the differences between a thesis statement and main idea, it's important to understand the components of an essay. Essentially, it's not a "versus" situation because the thesis statement and main idea cannot exist without the other.

difference between a thesis and purpose

Purpose of the Thesis Statement

The thesis statement is the foundation of the essay because it tells the reader what the essay will be about and gives the essay direction. The goals of the thesis statement are to organize and development your argument and provide your reader with a road map or guide to your argument. The thesis statement should answer a question about the topic you are exploring as a writer. A good thesis statement will express only one main idea and will assert your conclusion about a topic.

If you are given a topic to write about, it's important to first do your research and identify some main ideas associated with that topic. If you are writing about a piece of literature or specific work, you'll still need to do research but you will also need to read for key concepts or key ideas within that piece of writing first. Consider rereading the piece of literature to locate the main idea of the writer. Once you have located the main idea, you can then generate an opinion about the idea and create your thesis statement.

Developing the Main Idea

The topic of an essay is the subject, or what the essay is all about. An idea is what the writer says about the topic. The ideas include the main idea, which is then expressed in the form of a thesis statement. The main idea is not arguable like the thesis statement should be; it's simply an idea. Before writing, you should first develop the main idea because you cannot generate an arguable thesis statement about a topic until you have identified what you think of the topic.

Purpose of the Topic Sentence

The main idea of an essay is conveyed through the thesis statement and carried out through the topic sentences. An idea cannot be a statement, but a statement conveys an idea, hence the purpose of a thesis statement to state the point of an idea to convey to the reader in the development of an essay. Topic sentences also express the main idea. It's the first sentence of each subsequent paragraph in the essay and should be followed by supporting details, all supporting the topic sentence, which should support the main idea expressed in the thesis statement.

Module 4: Organizing and Outlining

The topic, purpose, and thesis.

Before any work can be done on crafting the body of your speech or presentation, you must first do some prep work—selecting a topic, formulating a purpose statement, and crafting a thesis statement. In doing so, you lay the foundation for your speech by making important decisions about what you will speak about and for what purpose you will speak. These decisions will influence and guide the entire speechwriting process, so it is wise to think carefully and critically during these beginning stages.

I think reading is important in any form. I think a person who’s trying to learn to like reading should start off reading about a topic they are interested in, or a person they are interested in. – Ice Cube

Questions for Selecting a Topic

  • What important events are occurring locally, nationally and internationally?
  • What do I care about most?
  • Is there someone or something I can advocate for?
  • What makes me angry/happy?
  • What beliefs/attitudes do I want to share?
  • Is there some information the audience needs to know?

Selecting a Topic

Painting of a person reading a book

“The Reader” by Shakespearesmonkey. CC-BY-NC .

Generally, speakers focus on one or more interrelated topics—relatively broad concepts, ideas, or problems that are relevant for particular audiences. The most common way that speakers discover topics is by simply observing what is happening around them—at their school, in their local government, or around the world. This is because all speeches are brought into existence as a result of circumstances, the multiplicity of activities going on at any one given moment in a particular place. For instance, presidential candidates craft short policy speeches that can be employed during debates, interviews, or town hall meetings during campaign seasons. When one of the candidates realizes he or she will not be successful, the particular circumstances change and the person must craft different kinds of speeches—a concession speech, for example. In other words, their campaign for presidency, and its many related events, necessitates the creation of various speeches. Rhetorical theorist Lloyd Bitzer [1] describes this as the rhetorical situation. Put simply, the rhetorical situation is the combination of factors that make speeches and other discourse meaningful and a useful way to change the way something is. Student government leaders, for example, speak or write to other students when their campus is facing tuition or fee increases, or when students have achieved something spectacular, like lobbying campus administrators for lower student fees and succeeding. In either case, it is the situation that makes their speeches appropriate and useful for their audience of students and university employees. More importantly, they speak when there is an opportunity to change a university policy or to alter the way students think or behave in relation to a particular event on campus.

But you need not run for president or student government in order to give a meaningful speech. On the contrary, opportunities abound for those interested in engaging speech as a tool for change. Perhaps the simplest way to find a topic is to ask yourself a few questions. See the textbox entitled “Questions for Selecting a Topic” for a few questions that will help you choose a topic.

There are other questions you might ask yourself, too, but these should lead you to at least a few topical choices. The most important work that these questions do is to locate topics within your pre-existing sphere of knowledge and interest. David Zarefsky [2] also identifies brainstorming as a way to develop speech topics, a strategy that can be helpful if the questions listed in the textbox did not yield an appropriate or interesting topic.

Starting with a topic you are already interested in will likely make writing and presenting your speech a more enjoyable and meaningful experience. It means that your entire speechwriting process will focus on something you find important and that you can present this information to people who stand to benefit from your speech.

Once you have answered these questions and narrowed your responses, you are still not done selecting your topic. For instance, you might have decided that you really care about conserving habitat for bog turtles. This is a very broad topic and could easily lead to a dozen different speeches. To resolve this problem, speakers must also consider the audience to whom they will speak, the scope of their presentation, and the outcome they wish to achieve. If the bog turtle enthusiast knows that she will be talking to a local zoning board and that she hopes to stop them from allowing businesses to locate on important bog turtle habitat, her topic can easily morph into something more specific. Now, her speech topic is two-pronged: bog turtle habitat and zoning rules.

Formulating the Purpose Statements

By honing in on a very specific topic, you begin the work of formulating your purpose statement . In short, a purpose statement clearly states what it is you would like to achieve. Purpose statements are especially helpful for guiding you as you prepare your speech. When deciding which main points, facts, and examples to include, you should simply ask yourself whether they are relevant not only to the topic you have selected, but also whether they support the goal you outlined in your purpose statement. The general purpose statement of a speech may be to inform, to persuade, to inspire, to celebrate, to mourn, or to entertain. Thus, it is common to frame a specific purpose statement around one of these goals. According to O’Hair, Stewart, and Rubenstein, a specific purpose statement “expresses both the topic and the general speech purpose in action form and in terms of the specific objectives you hope to achieve.” [3] For instance, the bog turtle habitat activist might write the following specific purpose statement: At the end of my speech, the Clarke County Zoning Commission will understand that locating businesses in bog turtle habitat is a poor choice with a range of negative consequences. In short, the general purpose statement lays out the broader goal of the speech while the specific purpose statement describes precisely what the speech is intended to do.

Success demands singleness of purpose. – Vince Lombardi

Writing the Thesis Statement

The specific purpose statement is a tool that you will use as you write your talk, but it is unlikely that it will appear verbatim in your speech. Instead, you will want to convert the specific purpose statement into a thesis statement that you will share with your audience. A thesis statement encapsulates the main points of a speech in just a sentence or two, and it is designed to give audiences a quick preview of what the entire speech will be about. The thesis statement for a speech, like the thesis of a research- based essay, should be easily identifiable and ought to very succinctly sum up the main points you will present. Moreover, the thesis statement should reflect the general purpose of your speech; if your purpose is to persuade or educate, for instance, the thesis should alert audience members to this goal. The bog turtle enthusiast might prepare the following thesis statement based on her specific purpose statement: Bog turtle habitats are sensitive to a variety of activities, but land development is particularly harmful to unstable habitats. The Clarke County Zoning Commission should protect bog turtle habitats by choosing to prohibit business from locating in these habitats. In this example, the thesis statement outlines the main points and implies that the speaker will be arguing for certain zoning practices.

Dissertation vs Thesis: The Differences that Matter

difference between a thesis and purpose

Updated: June 19, 2024

Published: April 26, 2020

Dissertation-vs-Thesis-The-Differences-that-Matter

As a graduate student, you will have many different types of challenging coursework and assignments. However, the biggest project that you’ll work on when earning your master’s or doctoral degree will be your thesis or dissertation . The differences between a dissertation vs thesis are plenty. That’s because each of these pieces of writing happen at different times in one’s educational journey.

Let’s break down what a dissertation and thesis are so that you have a strong handle on what’s expected. For both a thesis and a dissertation, there is an obvious fluency and understanding of the subject one studies.

Let’s take a look at their similarities and differences.

What is a dissertation.

When you enter a doctoral program to earn a PhD, you will learn a lot about how to conduct your own research. At the culmination of your degree program, you’ll produce a dissertation.

A dissertation is a lengthy piece of written work that includes original research or expanded research on a new or existing topic. As the doctoral student, you get to choose what you want to explore and write about within your field of study.

What is a Thesis?

A thesis is also a scholarly piece of writing, but it is for those who are graduating from a master’s program. A thesis allows students to showcase their knowledge and expertise within the subject matter they have been studying.

Main Differences Between a Thesis vs. Dissertation

The biggest difference between a thesis and a dissertation is that a thesis is based on existing research.

On the other hand, a dissertation will more than likely require the doctoral student to conduct their own research and then perform analysis. The other big difference is that a thesis is for master’s students and the dissertation is for PhD students.

Structural Differences Between a Thesis and a Dissertation

Structurally, the two pieces of written analysis have many differences.

  • A thesis is at least 100 pages in length
  • A dissertation is 2-3x that in length
  • A thesis expands upon and analyzes existing research
  • A dissertation’s content is mostly attributed to the student as the author

Research Content and Oral Presentation

Once completed, some programs require students to orally present their thesis and dissertation to a panel of faculty members.

Typically, a dissertation oral presentation can take several hours. On the other hand, a thesis only takes about an hour to present and answer questions.

Let’s look at how the two scholarly works are similar and different:

Similarities:

  • Each is considered a final project and required to graduate
  • Both require immense understanding of the material
  • Written skills are key to complete both
  • Neither can be plagiarized
  • Both are used to defend an argument
  • Both require analytical skills
  • You will have to draft, rewrite, and edit both pieces of writing
  • For both, it is useful to have another person look over before submission
  • Both papers are given deadlines

Differences:

  • A dissertation is longer than a thesis
  • A dissertation requires new research
  • A dissertation requires a hypothesis that is then proven
  • A thesis chooses a stance on an existing idea and defends it with analysis
  • A dissertation has a longer oral presentation component

The Differences in Context: Location Matters

The united states.

In the US, everything that was previously listed is how schools differentiate between a thesis and a dissertation. A thesis is performed by master’s students, and a dissertation is written by PhD candidates.

In Europe, the distinction between a thesis and dissertation becomes a little more cloudy. That’s because PhD programs may require a doctoral thesis to graduate. Then, as a part of a broader post-graduate research project, students may complete a dissertation.

The purpose behind written research.

Each piece of writing is an opportunity for a student to demonstrate his or her ability to think critically, express their opinions in writing, and present their findings in front of their department.

Graduate degrees take a lot of time, energy, and hard work to complete. When it comes to writing such lengthy and informative pieces, there is a lot of time management that is involved. The purpose of both a thesis and a dissertation are written proof that you understand and have mastered the subject matter of your degree.

Degree Types

A doctoral degree, or PhD, is the highest degree that one can earn. In most cases, students follow the following path to achieve this level of education: Earn a bachelor’s degree, then a master’s, and then a PhD. While not every job title requires this deep educational knowledge, the salaries that come along with each level of higher education increase accordingly.

Earning Your Degree

Whether you are currently a prospective student considering earning your higher education degree or a student enrolled in a master’s or doctoral program, you know the benefits of education.

However, for some, earning a traditional degree on-campus doesn’t make sense. This could be because of the financial challenges, familial obligations, accessibility, or any other number of reasons.

For students who are seeking their higher education degrees but need a flexible, affordable, and quality alternative to traditional college, take a look at the programs that the University of the People has to offer.

University of the People is an entirely online, US accredited and tuition-free institution dedicated to higher education. You can earn your Master’s in Business Administration or your Master’s in Education . Not to mention, there are a handful of associate’s and bachelor’s degree programs to choose from as well.

The Bottom Line

Regardless of where and when you earn your master’s or doctoral degree, you will likely have to complete a thesis or dissertation. The main difference between a thesis and dissertation is the level at which you complete them. A thesis is for a master’s degree, and a dissertation is for a doctoral degree.

Don’t be overwhelmed by the prospect of having to research and write so much. Your educational journey has prepared you with the right time management skills and writing skills to make this feat achievable!
