Modern psychological research shows that any knowledge is not acquired by indoctrination, but is actively constructed by learners with the help of necessary information resources in certain situations. A simple activity not only highlights the key points of teaching content, but also sets suspense, which vividly stimulates students' desire to explore new knowledge.

Second, cultivate students' personalized thinking

As an independent individual, each student has his own unique personality. In teaching, I pay more attention to students' needs and encourage students to think, explore and explain in different ways. Students' personality is flamboyant because of respect.

Third, provide hands-on space for students to actively participate in exploration.

An educator once said: "Children's wisdom is at your fingertips." Modern teaching theory also believes that students should do it with their hands instead of listening with their ears. Indeed, thinking often begins with human actions. If the connection between activity and thinking is cut off, thinking cannot develop. And hands-on practice is the easiest way to stimulate students' thinking and imagination. In teaching activities, teachers should attach great importance to students' direct experience, let students discover, understand and master new knowledge in a series of personal experiences, and let students develop their thinking ability by doing middle school mathematics, just like swimming in middle school.
