Through it, the teacher displays the physical phenomena to be studied in front of the students, stimulates students’ interest in observation, and enriches students’ perceptual knowledge. It plays an important role in inspiring students’ positive thinking, cultivating students’ active participation in classroom teaching, and improving students’ experimental ability. . This requires that physics teachers must pay attention to the demonstration of experimental teaching and fully recognize its role in cultivating students’ experimental ability and developing students’ innovative thinking.
