物理化学课程教学中如何设置情境问题

Setting Situational Problems in Teaching of Physical Chemistry Course

物理化学课程在教学中需要设置情境问题,设置需遵守教学"三基"要求,贴合情境且能吸引学生对知识发生顿悟。问题可以来源于生活、实验、教材,可以是引出概念问题、综合应用知识问题。以化学平衡为例通过有效的问题介绍了如何把生活案例、教材题目与知识点连接整合,突出标准平衡常数和反应吉布斯函数的物理量和化学平衡移动的判断方法,引导学生掌握最基本知识点,提高解决实际的化学反应平衡问题的能力。

The situational problems are needed to be set during the teaching of physical chemistry course. They need to comply with the three basic requirements of teaching,to fit the situation and to attract students to have an insight into knowledge. The problems can come from life,experiments and teaching materials. They could be the questions leading to concepts and the problems of comprehensive application of knowledge. This paper takes the chapter of chemical equilibrium as an example. The integration of the life cases and textbook topics with the knowledge is introduced through the effective problems. The physical quantities of standard equilibrium constant and reaction Gibbs function and the judgment methods of and chemical equilibrium movement are highlighted. All of them could guide students to master the most basic knowledge points and to improve the ability of solving the actual chemical reaction equilibrium problems.
