1. Effective questioning involves asking a variety of questions at different cognitive levels, including convergent, divergent, and evaluative questions. Teachers should aim to ask both lower-level and higher-level questions. 2. Important questioning skills for teachers include varying question types, not directing questions to specific students, calling on non-volunteers, rephrasing questions if needed, sequencing questions logically, and allowing sufficient wait time after asking a question. 3. Teachers can improve their questioning techniques by reflecting on the types of questions they typically ask, getting feedback from colleagues, increasing their repertoire of question types, considering students' abilities and interests, and spending time to improve the questions they ask.
