Usually researchers start out with a broad topic before narrowing it down to a question. These strategies can help with that process.
Create a visual map your topic that shows different aspects of the topic.
Think about questions related to your topic. For example, when researching the local food culture, you might consider:
Who, What, When, where, and Why (the 5 W’s).
These kinds of questions can help you brainstorm ways you might narrow your question.
