初三物理第四章、第十四章均有太阳能转化为电能的内容。但没有演示实验,学生不能亲眼观察到光电转化现象,影响了学生学习兴趣。为弥补这一不足,我在教学过程中增设了演示实验:“太阳能转化电能推动电子钟走时”,取得了很好的教学效果,下面介绍我的具体做法。 The fourth and fourth chapters of Physics in the third grade all have the content of solar energy being converted into electric energy. However, without demonstrating experiments, students could not observe the phenomenon of photoelectric transformation with their own eyes and affected students’ interest in learning. In order to make up for this deficiency, I added a demonstration experiment in the teaching process: “The conversion of solar energy to promote the electronic clock to go” has achieved very good teaching results. Here is my specific approach.
