利用前沿研究提高物理化学的教学效果

Improving Teaching Effect of Physical Chemistry by Combining the Course with Cutting-Edge Research

物理化学课程中抽象的概念、大量的公式以及结论的经典性容易给学生造成授课内容远离前沿研究的错觉。可以在授课过程中将前沿研究与课程内容相结合来改革物理化学教学。主要的实例包括:(1)利用ΔG判据分析利用水分解反应制取氢气的热力学要求;(2)利用离子互吸理论和双电层理论解释纳米孔的离子选择性;(3)基于化学势和电化学势的概念来推导浓差电池的电动势。通过揭示物理化学基本原理对上述前沿研究的指导作用来拓宽学生的视野,培养学生的学习兴趣,从而改善了课程的教学效果。

The abstract concepts,massive formulas and classical conclusions in the course of physical chemistry make the undergraduates feel that this course may be useless for the cuttingedge research.In order to overcome this false impression,we try to reform the teaching by combining the course with cutting-edge research.The main examples include the following three aspects:(1)The application of ΔG criterion to analyze the thermodynamic requirements of water splitting reactions for hydrogen generation under light or electricity;(2)The application of interionic attraction theory and electric double layer theory to explain the ion selectivity of nanopores; (3)The derivation of the electromotive force of concentration cells using the concept of chemical potential and electrochemical potential.This exploration on the role of fundamental principles in cutting-edge research broadens the students' horizons and interests in learning,which results in an improvement in the teaching effect.
