The search for a good thesis statement begins with a good research question. Your thesis is the answer to that question. As the thesis is a relatively long research paper, a good research question should be sufficiently broad. In general, this will mean avoiding “yes/no” questions or reframing such questions.
For instance, instead of asking
“Does race influence standardized testing in high schools in the UK?”
Reframe your question as
“How does race influence standardized testing in high schools in the UK?”
This will allow you to explore different aspects, analyze interactions among variables, and write a longer, more substantive paper.
While your thesis topic should be broad enough, it should never be vague. Your thesis topic will need to be clear and address a clearly defined research question. At the same time, the answer should contribute to a broader understanding of the research field.
If you create a thesis based on research questions like “How many kinds of fungi are there in the world?” or “What is love?,” you are going to end up writing a long, frustrating paper. A good thesis topic will answer a much more specific question, like:
“What kinds of fungi grow in the vicinity of drainage pipes?” or
“How do people in Myanmar express love during courtship rituals?”
In other words, a great thesis topic is your answer to a:
- Somewhat broad
- Very precise and
- Somewhat open-ended question.
While yes/no questions can be acceptable on rare occasions, you should avoid them or rephrase them, especially in science fields.
Finally, a great thesis topic fills a niche in a research field where research on the topic already exists, but there is still more to be discovered or new aspects to be explored. Alternatively, thesis topics could offer a fresh take on an old topic or rebuttals to a well-known theory. You don’t need to necessarily perform groundbreaking research; however, a great thesis topic will always offer a unique element that could make your thesis stand out.
