To create an effective thesis statement, consider these key components:

• Clarity : Clearly express your main argument.
• Specificity : Focus on a particular aspect of your topic.
• Debatable : Present an argument that invites discussion.
• Evidence : Support your claim with relevant examples.
• Coherence : Ensure all parts of your statement connect logically.

Common Pitfalls in Thesis Development

When developing your thesis statement, avoid these common mistakes:

How to Write a Thesis Statement | 4 Steps & Examples

Published on January 11, 2019 by Shona McCombes . Revised on August 15, 2023 by Eoghan Ryan.

A thesis statement is a sentence that sums up the central point of your paper or essay . It usually comes near the end of your introduction .

Your thesis will look a bit different depending on the type of essay you’re writing. But the thesis statement should always clearly state the main idea you want to get across. Everything else in your essay should relate back to this idea.

You can write your thesis statement by following four simple steps:

• Start with a question
• Write your initial answer
• Develop your answer
• Refine your thesis statement

A thesis statement summarizes the central points of your essay. It is a signpost telling the reader what the essay will argue and why.

The best thesis statements are:

• Concise: A good thesis statement is short and sweet—don’t use more words than necessary. State your point clearly and directly in one or two sentences.
• Contentious: Your thesis shouldn’t be a simple statement of fact that everyone already knows. A good thesis statement is a claim that requires further evidence or analysis to back it up.
• Coherent: Everything mentioned in your thesis statement must be supported and explained in the rest of your paper.

The thesis statement generally appears at the end of your essay introduction or research paper introduction .

The spread of the internet has had a world-changing effect, not least on the world of education. The use of the internet in academic contexts and among young people more generally is hotly debated. For many who did not grow up with this technology, its effects seem alarming and potentially harmful. This concern, while understandable, is misguided. The negatives of internet use are outweighed by its many benefits for education: the internet facilitates easier access to information, exposure to different perspectives, and a flexible learning environment for both students and teachers.

You should come up with an initial thesis, sometimes called a working thesis , early in the writing process . As soon as you’ve decided on your essay topic , you need to work out what you want to say about it—a clear thesis will give your essay direction and structure.

You might already have a question in your assignment, but if not, try to come up with your own. What would you like to find out or decide about your topic?

For example, you might ask:

After some initial research, you can formulate a tentative answer to this question. At this stage it can be simple, and it should guide the research process and writing process .

Now you need to consider why this is your answer and how you will convince your reader to agree with you. As you read more about your topic and begin writing, your answer should get more detailed.

In your essay about the internet and education, the thesis states your position and sketches out the key arguments you’ll use to support it.

The negatives of internet use are outweighed by its many benefits for education because it facilitates easier access to information.

In your essay about braille, the thesis statement summarizes the key historical development that you’ll explain.

The invention of braille in the 19th century transformed the lives of blind people, allowing them to participate more actively in public life.

A strong thesis statement should tell the reader:

• Why you hold this position
• What they’ll learn from your essay
• The key points of your argument or narrative

The final thesis statement doesn’t just state your position, but summarizes your overall argument or the entire topic you’re going to explain. To strengthen a weak thesis statement, it can help to consider the broader context of your topic.

These examples are more specific and show that you’ll explore your topic in depth.

Your thesis statement should match the goals of your essay, which vary depending on the type of essay you’re writing:

• In an argumentative essay , your thesis statement should take a strong position. Your aim in the essay is to convince your reader of this thesis based on evidence and logical reasoning.
• In an expository essay , you’ll aim to explain the facts of a topic or process. Your thesis statement doesn’t have to include a strong opinion in this case, but it should clearly state the central point you want to make, and mention the key elements you’ll explain.

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

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

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

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

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

Arguable thesis with analytical claim 

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

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

Arguable thesis with normative claim 

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

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

Questions to ask about your thesis 

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

Dissertation vs Thesis: Understanding the Key Differences

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.

What is a thesis?

What is a dissertation, getting started, staying on track, thesis abstract, lit(erature) review.

A thesis is a long-term project that you work on over the course of a semester or a year. Theses have a very wide variety of styles and content, so we encourage you to look at prior examples and work closely with faculty to develop yours. 

Before you begin, make sure that you are familiar with the dissertation genre—what it is for and what it looks like.

Generally speaking, a dissertation’s purpose is to prove that you have the expertise necessary to fulfill your doctoral-degree requirements by showing depth of knowledge and independent thinking.

The form of a dissertation may vary by discipline. Be sure to follow the specific guidelines of your department.

• PhD This site directs candidates to the GSAS website about dissertations , with links to checklists,  planning, formatting, acknowledgments, submission, and publishing options. There is also a link to guidelines for the prospectus . Consult with your committee chair about specific requirements and standards for your dissertation.
• DDES This document covers planning, patent filing, submission guidelines, publishing options, formatting guidelines, sample pages, citation guidelines, and a list of common errors to avoid. There is also a link to guidelines for the prospectus .
• Scholarly Pursuits (GSAS) This searchable booklet from Harvard GSAS is a comprehensive guide to writing dissertations, dissertation-fellowship applications, academic journal articles, and academic job documents.

Finding an original topic can be a daunting and overwhelming task. These key concepts can help you focus and save time.

Finding a topic for your thesis or dissertation should start with a research question that excites or at least interests you. A rigorous, engaging, and original project will require continuous curiosity about your topic, about your own thoughts on the topic, and about what other scholars have said on your topic. Avoid getting boxed in by thinking you know what you want to say from the beginning; let your research and your writing evolve as you explore and fine-tune your focus through constant questioning and exploration.

Get a sense of the broader picture before you narrow your focus and attempt to frame an argument. Read, skim, and otherwise familiarize yourself with what other scholars have done in areas related to your proposed topic. Briefly explore topics tangentially related to yours to broaden your perspective and increase your chance of finding a unique angle to pursue.

Critical Reading

Critical reading is the opposite of passive reading. Instead of merely reading for information to absorb, critical reading also involves careful, sustained thinking about what you are reading. This process may include analyzing the author’s motives and assumptions, asking what might be left out of the discussion, considering what you agree with or disagree with in the author’s statements and why you agree or disagree, and exploring connections or contradictions between scholarly arguments. Here is a resource to help hone your critical-reading skills:

https://guides.library.harvard.edu/sixreadinghabits  

https://youtu.be/BcV64lowMIA

Conversation

Your thesis or dissertation will incorporate some ideas from other scholars whose work you researched. By reading critically and following your curiosity, you will develop your own ideas and claims, and these contributions are the core of your project. You will also acknowledge the work of scholars who came before you, and you must accurately and fairly attribute this work and define your place within the larger discussion. Make sure that you know how to quote, summarize, paraphrase ,  integrate , and cite sources to avoid plagiarism and to show the depth and breadth of your knowledge.

A thesis is a long-term, large project that involves both research and writing; it is easy to lose focus, motivation, and momentum. Here are suggestions for achieving the result you want in the time you have.

The dissertation is probably the largest project you have undertaken, and a lot of the work is self-directed. The project can feel daunting or even overwhelming unless you break it down into manageable pieces and create a timeline for completing each smaller task. Be realistic but also challenge yourself, and be forgiving of yourself if you miss a self-imposed deadline here and there.

Your program will also have specific deadlines for different requirements, including establishing a committee, submitting a prospectus, completing the dissertation, defending the dissertation, and submitting your work. Consult your department’s website for these dates and incorporate them into the timeline for your work.

Accountability

Sometimes self-imposed deadlines do not feel urgent unless there is accountability to someone beyond yourself. To increase your motivation to complete tasks on schedule, set dates with your committee chair to submit pre-determined pieces of a chapter. You can also arrange with a fellow doctoral student to check on each other’s progress. Research and writing can be lonely, so it is also nice to share that journey with someone and support each other through the process.

Common Pitfalls

The most common challenges for students writing a dissertation are writer’s block, information-overload, and the compulsion to keep researching forever.

There are many strategies for avoiding writer’s block, such as freewriting, outlining, taking a walk, starting in the middle, and creating an ideal work environment for your particular learning style. Pay attention to what helps you and try different things until you find what works.

Efficient researching techniques are essential to avoiding information-overload. Here are a couple of resources about strategies for finding sources and quickly obtaining essential information from them.

https://students.dartmouth.edu/academic-skills/learning-resources/learning-strategies/reading-techniques

Finally, remember that there is always more to learn and your dissertation cannot incorporate everything. Follow your curiosity but also set limits on the scope of your work. It helps to create a folder entitled “future projects” for topics and sources that interest you but that do not fit neatly into the dissertation. Also remember that future scholars will build off of your work, so leave something for them to do.

An abstract is a short (approximately 200-word) summary or overview of your research project. It provides enough information for a reader to know what they will find within the larger document, such as your purpose, methodology, and results or conclusion. It may also include a list of  keywords. An abstract is an original document, not an excerpt, and its contents and organization may vary by discipline.

A literature review establishes a set of themes and contexts drawn from foundational research and materials that relate to your project. It is an acknowledgment that your scholarship doesn’t exist in a vacuum. With the review, you identify patterns and trends in the literature to situate your contribution within the existing scholarly conversation.

What is a literature review? A literature review (or lit review, for short) is a critical analysis of published scholarly research (the "literature") related to a specific topic. Literature here means body of work, which traditionally was done in written form and may include journal articles, books, book chapters, dissertations and thesis, or conference proceedings. In the case of design, however, literature has an expanded breadth since the body of work is oftentimes not represented by words. A design review may include plans, sections, photographs, and any type of media that portrays the work.

A literature review may stand on its own or may be inside a larger work, usually in the introductory sections. It is thorough but not exhaustive--there will always be more information than you can reasonably locate and include. Be mindful of your scope and time constraints and select your reviewed materials with care. A literature review

• summarizes the themes and findings of works in an area
• compares and contrasts relevant aspects of literature on a topic
• critically assesses the strengths and omissions of the source material
• elaborates on the implications of their findings for one's own research topic

What does a literature review look like? Each discipline has its own style for writing a literature review; urban planning and design lit reviews may look different than those from architecture, and design lit reviews will look significantly different than reviews from the biological sciences or engineering. Look at published journal articles within your field and note how they present the information.

• Introduction: most scholarly articles and books will have a literature review within the introductory sections. Its precise location may vary, but it is most often in the first few paragraphs or pages.

Dedicated literature reviews: these are stand-alone resources unto themselves. You can search for "literature review" and a topic, and you may find that one already exists. These literature reviews are useful as models within your field, for finding additional sources to explore, and for beginning to map the general relationships within the scholarly conversation around your topic. Be mindful not to plagiarize the source material.

Database search tip : Add the phrase "literature review" to your search to find published literature reviews.

Browsing through theses and dissertations of the past can help to get a sense of your options and gain inspiration but be careful to use current guidelines and refer to your committee instead of relying on these examples for form or formatting.

What is the Difference Between a Dissertation and a Thesis?

Find your perfect postgrad program search our database of 30,000 courses.

And to make it even more confusing, some institutions or departments will even use the terms differently!

But what are we all really talking about when we refer to a dissertation or a thesis? And does the term you use actually impact on what you actually end up writing?

This article covers the main differences between a dissertation and thesis, and how the terms may differ depending on the course, university and location.

What is a dissertation?

A dissertation is a piece of academic writing centred around original research. In their dissertations, students review existing research but also build on this with unique hypotheses and approaches.

A dissertation can be used to disprove a previous theory or take existing theories and research in a new direction. It is a large research project that is usually completed at the end of the academic year.

Usually, a dissertation starts with a dissertation proposal , which is approved by a study supervisor. The student then completes the research and writes up the methodology , findings, evaluations and conclusions from the research.

Dissertations can be undertaken by both undergraduate and postgraduate students. At undergraduate level the word count is around 5,000 to 8,000 and at postgraduate level it is usually 10,000 to 15,000.

What is a thesis?

A thesis is an academic paper covering an in-depth review of existing research in a particular discipline. It will involve an academic argument, although it doesn’t usually require original research from the student. The existing research is used to support and evaluate the proposed argument.

A thesis is not usually required at undergraduate level and is more common at postgraduate level.

This large piece of written-up research is usually completed at the end of a masters degree. Some masters courses require a thesis to graduate.

Differences between a dissertation vs thesis

The main purpose of a writing a dissertation is to add new findings to the existing literature in that field with original research. Whereas theses tend to evaluate existing findings, as their purpose is to demonstrate knowledge and skills within the course’s subject matter.

In terms of how long it takes to complete a thesis or dissertation project, a thesis is typically shorter than a dissertation since there are fewer original research aspects involved. This means that it will probably take less time. However, this can differ depending on the university and the course.

Dissertations sometimes require an oral presentation, known as a viva , where findings are showcased to academics who ask questions about the research. Theses usually do not require this.

The root of the words 

The word ‘dissertation’ originates from the Latin word ‘dissertare’, meaning to continue to discuss and the Latin word ‘disserere’ which means to examine and discuss .

The word ‘thesis’ originally comes from the Greek word ‘tithenai’, which means to place or position. This later evolved into the Latin ‘thesis’, which had two meanings: an abstract question and to put something forward .

Similarities between a dissertation vs thesis

Although there are some key differences between a dissertation and a thesis, there are also similarities.

• Both are generally long pieces of academic writing, much longer than a typical essay.
• Both explore a topic in depth, whether you are conducting totally unique research or structuring an argument based on existing research.
• Both are considered a final project and usually required to graduate from a degree, masters or PhD. Students can graduate without a thesis or dissertation if they choose to complete a postgraduate diploma or postgraduate certificate instead.
• Excellent academic writing skills are highly important for both types of research project.

Is a dissertation harder than a thesis?

Though, the difficulty of a thesis or dissertation depends on your personal skill set. For instance, students that learn better by developing their own research ideas may find a dissertation easier than a thesis.

Difficulty can also depend on the level of the course. For instance, a thesis completed at doctorate level is likely to require more advanced knowledge than a thesis at undergraduate level.

The difficulty of either type of research project can also vary depending on the subject matter and the resources available to you.

Both dissertations and theses can be challenging, but don’t be put off by the thought of having to produce a larger body of work. Your supervisor will be there to support you.

Definitions depend on where you are

The terms ‘dissertation’ and ‘thesis’ are sometimes used interchangeably, and the meanings can differ depending on the country and university.

There are plenty of differences between the variant forms of English, such as British English and American English. Around the world, different English-speaking countries use the words ‘dissertation’ and ‘thesis’ differently. 

Generally, nations with British-based academic systems of university education use dissertation to refer to the body of work at the end of an undergraduate or masters level degree . British-based institutions generally use thesis to refer to the body of work produced at the end of a PhD . 

In countries and institutions that are based on the American system of education, the words tend to be used in reverse. However, institutions and even different departments in the same university can use the words differently. 

If you're in doubt, then stick with the way the university and department you're currently attending use the terms. 

Definitions can depend on the subject

In the UK, the terms ‘dissertation’ and ‘thesis’ are generally applied equally across institutions and subjects. 

However, in the US the meanings can differ between different subject areas. The term ‘thesis’ can be used to describe a piece of original research in US academia, whereas original research is usually referred to as a dissertation in the UK. 

If you’re studying in the US , you may complete a thesis at masters level in another subject area that involves wide-ranging reading and understanding rather than original research and still call it a thesis.

With so much interchangeability between the two terms, it’s understandable that there is often confusion in the debate between a dissertation vs thesis, as there is no clear answer. 

Always read specific course details to understand exactly what’s involved in the research project that you are required to produce.

Examples from US and UK universities

Georgetown University in the US refers to a dissertation and a thesis as both adding to your 'field of knowledge' . The University of Edinburgh recommends that you refer to your individual course handbook for guides to dissertations, so each department will have their own guidelines to using the word dissertation and thesis. At University College London they refer to a thesis as the piece of work at the end of an EngD, MPhil, MD(Res) or PhD, which are all research degrees. 

In conclusion

Ultimately, it doesn't really matter which word you use as both refer to a serious and lengthy piece of work where you can show what you have researched and understood as part of your postgraduate studies.

As long as you are referring to the piece of work that you are compiling in the same way as those in your department then you will avoid confusion.

It is important to check whether the research piece involves original research or expects you to build upon existing research.

Writing a dissertation or a thesis requires a substantial amount of planning and work and you don't want to let yourself down at the last hurdle with poor presentation of your work, so always keep an eye on your course or department guidelines.
