Three Filters for Testing a Thesis Topic
Most thesis topics begin as a wide interest: digital marketing, student mental health, river water quality. Something that broad cannot be researched in a single semester, so the student's first job is to filter it. The first filter asks whether the data is within reach, meaning respondents can be found, documents can be accessed and any institutional permission can realistically be obtained in time. The second asks whether a theory exists to build on. The third asks whether the problem still leaves room for new work, which the student checks by reading five to ten recent theses and journal articles on similar themes.
A topic that clears all three filters is then written as one sentence containing the variables, the subjects and the setting. An interest in digital marketing, for instance, narrows into the effect of short-form video content on the purchasing decisions of university students in one city. A sentence like that tells the supervisor at a glance what is being measured, among whom and where, so the first supervision meeting can move straight into substance.
Data access is where students most often get caught. Plenty of them discover that company or agency data is hard to obtain only after the proposal has been approved, and end up changing topic halfway through. A habit that helps is contacting likely data sources before submitting the title, and bringing the draft topic to the supervisor early so its direction fits the supervisor's own field.
A topic is ready to submit once its data is reachable, its theory exists, its gap is visible, and the whole thing fits in one sentence of variables, subjects and setting.
