First, the issue put forward (a) the traditional lesson plans teaching difficult to meet the requirements of the times For a long time, many students are afraid to learn physics, that physics is a very difficult subject, teaching physics teachers generally feel very difficult to teach, teachers tend to Speak many times, students still do not understand. “Students difficult to learn, teachers difficult to teach ” has become an urgent problem to be solved in physics teaching. The United States Joseph Treinerman test the classroom teaching found that: teachers explain 15 minutes, students can remember 41%; explain 30 minutes, only remember 23% of the first 15 minutes; explain 40 minutes, only remember 20 %. The conclusion of this experiment
