Defining Your Research Question
Once a student has submitted a proposal and they have an assigned Supervisor, they can work with them to refine a working research question. It's important for students to make sure that their research question is focused and lends itself to the scope and format of the Extended Essay. This must be a question that can be investigated in-depth, but should not be too broad or too narrow.
READ Chapter 2 of the Oxford Guide - this will give students very valuable advice about using "limiting factors" to narrow down your research question.
