以液体表面张力系数测量实验为例的PBL教学模式探讨

Application of problem-based learning teaching model in the experiment of liquid surface tension coefficient measurement

针对传统物理实验的教学模式中的缺点,基于建构主义教学理论,在物理实验教学引入了PBL教学模式.以拉脱法测量液体表面张力系数实验为例,探讨了PBL教学模式的具体应用,实践证明PBL教学模式有效地提高和促进了学生的认知学习和合作学习.

To overcome the shortcomings of traditional physical experiment teaching model,the problem-based learning（PBL） teaching model was introduced into the liquid surface tension coefficient measurement experiment with put-out method based on the constructivism theory.It effectively encouraged and increased the students＇ cognitive and cooperative learning.
