What question do you want to try to answer that's under the umbrella of your research topic? Doing some initial research will help you come up with some possible directions and will also help you feel out your topic: have other people actually done research on it before that you can use as your sources? Has enough time passed for meaningful research to have been published?
Most importantly, though: think about what interests you! You're going to be spending many hours with this subject, after all.
Once you know your topic and your research question, you need to figure out how you're going to find more in-depth information.
First, pick out the key terms from your research question:
What effects on the education system does racial discrimination have?
Next, you'll want to brainstorm some related and alternate terms for these keywords to give you some variability in your search strategies.
|Results||Charter schools||Specific examples: black, Hispanic, etc||Bias|
|Completion rates||Secondary school||Inequity, inequality|
|Retention rates||School funding||Affirmative action|
|Education gap||Socioeconomic clusters in school zoning|
