表面张力系数的实验探究

Experimental Inquiry on Liquid Tension Coefficients

“脱拉法测定液体的表面张力系数”是普通物理实验基本题目之一.本文介绍了改进实验教学方法的尝试:将科学探究引入实验教学.实验探究分为三个相互联系的过程:学生实验,提出问题;小组活动,探究结果;交流评估,促进提高.

Determining Liquid Tension Coefficient by Pulling and Separating Method is one of basic subjects in general Physics experiment. This paper introduces a new teaching method on this experiment. The new method is scientific inquiry. Experiment inquiry includes three processes： Students experiment and propose science questions, group acts and investigates results, communicating and assessing.
