Great changes have taken place in modern students's way of thinking and behavior. They are lively by nature and hate simple theoretical teaching. Creating situations is an enlightening problem for teachers to introduce meaningful phenomena or life experiences in real life into the classroom before teaching begins. Because students are familiar with these daily lives, they will have greater interest in learning and stimulate their desire for job hunting to some extent. In formal teaching, students will keep this enthusiasm, thus realizing the optimization of classroom efficiency.

Second, set a certain gradient on the problem.

Mathematics teaching is a step-by-step process, especially the knowledge points of high school mathematics, which are difficult to master. If a certain gradient is set in teaching, from simple to complex, from shallow to deep, students' interest in learning and exploration ability will be greatly improved. There will also be a sense of accomplishment when solving difficult problems, thus stimulating potential, activating thinking and improving classroom effect.

Third, strengthen student cooperation.

Students have different ways of thinking, and the same question often has different answers. Teachers should make use of this difference to group students according to their learning ability, so that students with strong learning ability can help students with weak learning ability, promote exchanges and cooperation between students, and let students learn from each other and make progress together in exchanges.
