A scholar constantly asks fundamental questions about the facts and techniques that make up his or her discipline. The scholar then answers these questions in unique and original ways. Because of the importance of questions to the research process, one of the things a teacher at a university tries to teach students is how to ask good questions, and how to answer them appropriately. This makes the process of questioning important in every class taught at a university. Students learn to ask good questions by asking questions and then receiving feedback on them.
Students learn to become scholars by learning to ask good questions.
This is the behavior we are trying to nurture. If you begin to talk at too high a level, students will stop understanding and thinking, and will ask no questions. Questions tell you whether your class is asleep or awake. If encouraged, students will ask questions about concepts they do not understand. These questions give you immediate feedback when you are unclear, and tell you where you need to spend more time.
