This document discusses defining a researchable problem and formulating good research questions. It provides sources for finding problem ideas such as news, personal experiences, and reviewing previous research. The key aspects of focusing a problem are defining it formally with words, using examples, or procedurally with a method. Good research questions are focused, empirical, clear, based on prior work or theory, important to answer, avoid "should" statements, and have intuitive appeal. The document outlines exploratory, descriptive, explanatory, predictive, and evaluative types of research questions.
