大家都知道,一节物理课的课题引入是非常重要的,如果设计得好,一开始就可以使学生明确课题,引起学生对课题的强烈兴趣,激发他们的求知欲望。如果用合理的实验来引入,效果会更佳。本人在讲授《自感》一课时,是用自己设计的电鱼这一实验引入的。1实验器材J2425型学生可拆变压器的 Everyone knows that the introduction of a physics class topic is very important. If it is well designed, students can clearly identify topics at the outset, arouse students’ strong interest in topics, and stimulate their desire for knowledge. If it is introduced with reasonable experiment, the effect will be better. When I was teaching “Self-induction”, I introduced this experiment with my own design of electric fish. 1 Experimental equipment J2425 student removable transformer
