使用相同的器材,做相同的实验,若采用不同的教法,效果会大不相同。对此,笔者在初中物理教学时,做过一些有益的探索。1.讨论实验法讨论能强化信息对大脑的刺激,加强识记效果。对要求学生识记的实验,采用先讨论后实验的方法效果较好。教师先引导学生结合已有知识,讨论实验可能产生的现象,当他们各自坚持自己的观点谁也说服不了谁时,就急于观看实验来验证自己的推断。这时,教师
Using the same equipment, doing the same experiment, if using different teaching methods, the effect will be very different. In this regard, the author did some useful explorations in physics teaching in junior middle school. 1. Discussion The discussion of experimental methods can strengthen the stimulation of information on the brain and enhance the memo effect. For experiments requiring students to memorize, the method of first discussing the post-experiment is better. Teachers first guide students to combine existing knowledge and discuss the phenomena that may occur in the experiment. When they each insist on their point of view who can not convince anyone, they rush to watch experiments to verify their own inferences. At this time, teachers
