First, the content is closely related to the main points and difficulties.

The content of questions in lecture hall should closely follow the main points and common sense of professors in lecture hall, activate students' thinking and improve their learning ability. The content of questions should be enlightening, and the questions raised should stimulate students' positive thoughts. The main points of education and common sense of difficulties make students most interested in the lecture hall. The questions raised must be scientific and reasonable, and should be closely related to the main points of education. Only in this way can we mobilize students to think positively, to mobilize students to follow the educational rhythm of the lecture hall, to enliven the atmosphere of the lecture hall, to enhance the communication between teachers and students, and to improve the educational effect.

Second, ask questions and push them at different levels.

Asking questions in the lecture hall should have a gradient, which is easy first and then difficult, which conforms to the cognitive law of students. This progressive method, which goes from the simple to the deep, interlocking and paving the way, not only solves the problem very easily, but also makes the students' thinking develop into common sense. It enables students to master the differences and connections between the elements of things, which is helpful to master the integrity.

Third, the lecture hall needs a lively atmosphere to ask questions.

Teachers' classroom questions should be put forward according to the educational content of the classroom and the problems that students are particularly interested in. It is beneficial to arouse students' enthusiasm for thinking. The contents in textbooks are often abstract and monotonous, and there are many contents that students can hardly see or easily master now. Ask questions to make students feel easy to answer. I feel that answering questions is just a process of reading textbooks, so that students will feel uninterested in the questions raised by teachers for a long time. Therefore, find some questions that students are interested in and closely related to the educational content as the starting point of lecture hall education, mobilize students' positive thinking, improve all students' automatic learning ability, and let every student try the joy of success. The generation gap between teachers and students is eliminated in the question and answer between teachers and students, which shortens the interval between teachers and students, enhances the emotional communication between teachers and students and greatly improves students' intelligence.
