First, be prepared to ask questions. Prepare questions and talk plans. Before class, teachers should prepare the order of questions and dialogues according to the teaching content and students' existing experience and knowledge, and how to lead from one question to another.

Second, the questions should be clear and wonderful, that is, challenging and inspiring, and the difficulty of the questions should vary from person to person.

Third, we should be good at inspiring and inducing. When asking questions, we should be good at inspiring students, analyzing and thinking about the perceptual knowledge gained by using students' existing knowledge and experience or observing intuitive teaching AIDS, studying contradictions, and using situations to guide students to acquire new knowledge step by step.

Fourth, we should do a good job of induction and summary, make students' knowledge systematic and scientific, and pay attention to correcting some incorrect understandings to help students master knowledge accurately.
