Questions, questions, questions! They are a large part of a teacher?s stock-in-trade. We use questions to help students review, to check on comprehension, to stimulate critical thinking, to encourage creativity, to emphasize a point, to control classroom activities, reduce disruptive behavior, to help determine grades, to encourage discussion, to discourage inattentiveness, and for other reasons and purposes. Questioning style and content varies from teacher to teacher, student group to student group, and situation to situation.
