For example, when learning the part

For example, when learning the part of "atmospheric pressure", it is difficult for teachers or students to really carry out the experiment in class, such as the need for various teaching equipment such as air pumps; When learning "how fast liquid evaporates", it takes a long time to observe the experimental results. When learning "molecular and atomic physical properties", it is difficult to carry out experiments due to objective conditions. For the study of this part of experiment content, teachers can update their original concepts of physics experiment, carry out virtual experiment by using multimedia equipment, let students feel the experiment principle from multimedia video or animation demonstration, observe experimental phenomena, raise experimental questions, and guide students to actively observe and learn, so as to improve the efficiency of physics experiment learning. Let the students understand the relevant knowledge points from the experimental point of view. The content of experiment is an important part of physics teaching in junior middle school, and it is also the content that can best cultivate students' comprehensive ability. Therefore, in classroom teaching, teachers must attach importance to the innovation of experimental teaching methods, increase the input of experimental teaching conditions, highlight students' main position in class, use new equipment to assist teaching and other ways. Actively guide students to participate in the learning of physics experiment content, encourage students to practice and think deeply, promote the improvement of students' comprehensive ability, so as to meet the requirements of quality teaching in the new era, further promote the development of junior high school physics experiment teaching innovation in middle school physics experiment teaching in the process of middle school physics experiment teaching, it should be determined to be based on experiment. Use experiments to stimulate students' interest in experiments, exert students' initiative and enthusiasm in participating in teaching, and cultivate students' practical ability and creative ability of operating experiments and designing experiments.
