Something has drawn your interest to the topic you have chosen. Maybe something about the topic either violates or exceeds the expectations you had of it. Or it challenges or appeals to values you hold. Or something about it surprises or puzzles you.
That is called dissonance, and is the start of most inquiry. You can harness your dissonance to develop a research question.
With your preparation and your consideration of your dissonance in regard to your topic, you are ready to frame a question. Your question will be about your puzzlement or dissonance as much as it is about your topic, and will also identify or at least suggest what you need to know to begin to answer your dissonance.
Pay attention to your own interests and dissonance, and those that are most prominent and important to you. But avoid a question that you already know the answer to.
Don't limit yourself to just one question. You can try several questions at first and then focus on one, or combine a few into one to get started. As your research progresses, be open to revising and altering your question.
Think about whether your question is open-ended or closed-ended. A closed-ended question can be answered with yes, no, or just a few words. An open-ended question requires an extended statement.
