The document discusses developing focused research questions that provide structure to an information search. It recommends starting with a general topic and refining it with a question word like who, what, when, where, why or how. Four types of questions are described - yes/no, one-word "inch" questions, multi-sentence "foot" comprehension questions, and multi-source "yard" synthesis questions. The document advises that "foot" and "yard" questions are better choices for most middle and high school research as they involve higher-level thinking skills. Good research questions should be interesting, researchable, significant and manageable in scope.
