现行高中物理课本 (试验修订本 )中不少章节正文后面有提供学生课外做的小实验“做一做” ,这些小实验简单易行、生动有趣 ,对学生进一步理解物理概念和规律、提高学习物理兴趣大有好处 .我们在平时的教学中将有些小实验改为课堂的学生实验或演示实验 ,获得了很好的效果 .在课 In the current high school physics textbook (trial revision), there are many small experiments that students do outside of class to do “do one”. These small experiments are simple, lively and interesting. They further understand the physical concepts and laws and improve learning. The physical interest is of great advantage. In the usual teaching, we changed some small experiments to classroom student experiments or demonstration experiments and achieved good results.
