基于网络教学平台的PBL教学模式在物理化学实验教学中的实践

PBL Teaching Mode of Physical Chemistry Experiment Based on Network Teaching Platform

基于网络教学平台系统,结合“蔗糖水解速率常数的测定”“液体饱和蒸气压的测定”“燃烧热的测定”等3个物理化学常规实验,介绍了在物理化学实验教学中实施以问题为导向的教学法(PBL)的具体实施步骤,探讨了该教学模式在化学实验教学实践中的应用.结果表明该教学模式教学效果良好,具有一定的推广价值.

Combined with three conventional physical chemistry experiments such as measurement of sucrose hydrolysis rate constant, determination of liquid saturation vapour pressure and combustion heat, specific implementing steps of the teaching method of problem-based learning(PBL) in physical chemistry experiment based on the network teaching platform were introduced. And teaching mode in chemical experiment teaching practice was discussed. The result showed that the teaching effect was good and this teaching mode had certain popularized value.
