关于“气垫导轨实验中光电计时系统误差研究”实验的探索

Exploration for teaching method of an air track experiment with system error caused by photoelectric timer

在全面解析"气垫导轨实验中光电计时系统误差研究"实验案例的基础上,对从学生兴趣入手,以学生发现作为实验研究的起点,依托学生在实验中自己发现的问题而将其设置成为一种设计性实验的实验方式进行了探讨.

We analyze the whole process of the air track experiment with system error caused by photoelectric timer. Considering the students＇ interest, we propose a new teaching method in which the demonstration experiment is replaced by the design experiment on the basis of the problems found by students in experiment.
