Editorial Listing ShortCode:
You’ll also maintain communication with your dissertation advisor to gain feedback throughout the dissertation writing process.
These are the 10 major steps that go into creating a dissertation:
- Select a topic you’re interested in. A dissertation topic generally has some area where there’s a current gap in research or knowledge that you can build upon.
- Begin conducting preliminary research on your topic. At this stage, you can begin taking notes of current findings or theories on your topic to gain an understanding of what information is already out there. You can also formulate any questions you may answer later in your dissertation.
- Write and submit a research proposal. The research proposal will be submitted to your dissertation advisor. It introduces what you plan to address in your dissertation and the research methodology you’ve selected.
- Conduct in-depth research. This is when you’ll take a deep dive into your topic and consume as much knowledge as you can to identify gaps in research relevant to your topic and develop your key findings.
- Create an outline for your dissertation paper. It’s recommended to create an outline of your dissertation to break down what needs to be included and how you want to structure the paper.
- Write the first draft. The first draft can help you organize all your ideas and discussions for each chapter. It doesn’t have to be perfect, but it may help you identify sections or ideas that may need to be revised later.
- Rework the first draft. After you’ve completed the first draft, you may make changes to the structure of your paper, remove or add sentences, look for any spelling or grammatical errors, and ensure that the paper is readable.
- Write the final draft. One of the last stages in the dissertation writing process is working on the final draft. This is where the structure of your paper, your thoughts, and your findings all come together to create a clear and concise dissertation ready for defense.
- Edit the final draft. A final review of your dissertation can help you identify anything you could’ve missed in your first round of editing. You’ll also revise any sections you added.
- Prepare for your dissertation defense. Dissertation advisors usually don’t allow you to move onto the dissertation defense step until they know you’re ready. Your advisor may ask you to make additional changes to your dissertation before you start preparing for the dissertation defense process.
Communicating with your dissertation advisor and other members of your dissertation committee is important to receive valuable feedback. The dissertation committee is there to support you through this process, and they may offer additional sources for you to review to create a stronger dissertation.
You can also look at other dissertations in your field of study to get an idea of how to structure your dissertation and clearly communicate your ideas.
Typical Dissertation Chapters
The structure of a dissertation can vary depending on your topic, discipline, and the guidelines provided by your school.
Major differences in dissertations can be seen between STEM doctoral programs versus non-STEM programs. Although there are some differences, most dissertations include these chapters:
- Introduction. The first chapter of a dissertation is the introduction. It briefly explains your dissertation topic and relevant background information, and it introduces the reader to your thesis statement or research question.
- Literature Review. This section serves as a discussion of the primary and secondary sources you’ve used throughout your research process, and it identifies the research gap that you intend to resolve in the remaining chapters.
- Research Methodology. All of the methods you’ve chosen to conduct your research are described in this section, including when and where you gathered your data, how you gathered data or conducted tests, and any challenges you faced during this process.
- Results. This chapter is reserved for discussing all of your findings, which should answer your research question or address your doctoral thesis.
- Conclusion. The conclusion chapter summarizes your dissertation. It may include answering your research question or revisiting your thesis statement and findings, but it shouldn’t include any new evidence or data.
Along with these chapters, a dissertation also includes a title page, abstract, table of contents, and bibliography. Some dissertations have an acknowledgment page, list of figures and tables, abbreviations page, and glossary.
