Choose a component or angle that interests you. Perhaps one on which there is already some controversy. Now formulate your research question. It should allow for reasoning as well as gathering of information – not just what the proto-Iroquoians of corn. For instance, but how valid the evidence is for early introduction of corn. You may even want to jot down a tentative thesis statement as a preliminary answer to your question.
๏ then you will know what to look for in your research reading: facts and theories that help answers your question, and other people’ s opinions about whether specific answers are good ones.
