12 Dissertation Writing Mistakes You Must Avoid

1. Choose the Wrong Dissertation Topic

There are many ways to screw up your dissertation and the most common among them is selecting the wrong research topic. It is saying without any doubt that if you start with the wrong topic, there are fewer chances to write a high-quality dissertation and earn your desired academic grades.

You can make this mistake in two ways: 

  • First, you can choose a topic that is too narrow, so that you only find a little information to support your argument. After choosing that topic, you end up writing your thesis in fewer words or pages than the recommended limit by your professor. The best way to avoid this is to change your topic and select a wider one.
  • The second is that you pick a broad topic, which becomes an uphill battle for you to cover every aspect of your topic within the word count. Choosing a broad topic will make it hard for you to even find a direction, as there are too many sources to look through. This eventually led you to write a coherent paper. Thus, it is better to narrow your topic down by choosing a subtopic or subfield.

2. Craft a Weak Dissertation Title

Sometimes, students put all their efforts into choosing the right topic and don’t bother with the title of their thesis. Nonetheless, little of your dissertation is as important as your topic. Therefore, you must write a compelling title to appeal to your audience because if your title lacks appeal, your readers are most likely not going to read your dissertation further.

The most common mistakes that students make while crafting the title of their dissertations include the following:

  • If you don’t know the exact message of your research, then there are higher chances that you will add too many details in your title and make it complex for readers to understand your key idea. To avoid this, it is better to only focus on one key idea instead of several. Also, make sure your title is as short as possible.
  • Some students add the acronyms in their titles, and readers have to do some extra research to understand the titles. Therefore, it is better to spell these acronyms to improve their understanding.
  • In addition, using jargon in your title is another big mistake. Therefore, you must avoid them because most of your readers will not understand them and end up giving up reading your dissertation.

3. Let the Formatting Mistakes be Unresolved

A dissertation is the only academic document whose format is highly specific, so students commonly, students face formatting problems while writing this document. Below are some common formatting mistakes that they make during dissertation writing:

  • Not following the word count limit
  • Improper numerals

So, it is totally okay if your dissertation contains formatting errors. The thing is you must make efforts to avoid these mistakes in your dissertation so your instructor knows that you took this paper seriously and did hard work.

  • During the editing stage, make sure that there is no inconsistency in the formatting of your headings and subheadings to ensure a clear and flawless academic document.

4. Write a Poor Thesis Statement

A thesis statement is the most important element of your dissertation, as your entire research is based on it. Therefore, you must write an effective and clear statement that helps you to take your research in the right direction.

To write a clear and compelling thesis statement, you must consider various criteria, including:

Criteria to Write a Good Thesis Statement

  • Clarity: Make sure that your statement is clear and easily understandable by your readers. For this, you must avoid complex and confusing words that make it hard for your readers to understand the essence of your research.
  • Specificity: The next thing that you must consider while writing your thesis statement is the specificity of your statement. Make sure that your statement is to the point and specific. For example, instead of writing ‘An investigation of advanced methods in certain scientific conditions’, write ‘Explore the application of X method under Y and Z conditions’.
  • No Simple Answer: When you write your statement, keep in mind that it requires in-depth analysis rather than a shallow description of your topic.
  • Originality: Originality is the key consideration for your thesis. You must write a thesis which comprises your original idea rather than stating the modification of the existing research model.
