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.
|Specific examples: black, Hispanic, etc
|Socioeconomic clusters in school zoning
Notice that I've struck out a couple terms...we don't want to accidentally broaden our search or our research question. Charter schools and college (secondary education) are too different from K-12 public schools, so I don't want to mix them. In fact, there's a big difference between elementary (the "K" end) and high schools (the "-12" end)...I'd want to see what I can easily find research for and really focus in on one or the other.
Now, when you take advantage of the advanced search tool in the databases, you'll be armed with a variety of search terms that relate to your topic!
You can search for the obvious, effects AND education AND race AND discrimination ... but you can also mix it up:
