物理化学课程中热力学基本公式识记技巧

Skills of Memorizing Basic Formulas of Thermodynamics in the Course of Physical Chemistry

在物理化学课程中,特性函数与特征变量概念、热力学基本方程以及麦克斯韦关系式均是化学热力学的重点教学内容.持久、准确识记上述函数关系及其重要公式是理解掌握上述热力学知识点的基础与前提,然而学生往往记不住,记不牢.识记这些知识点成为教学中的难点.教学实践证明,运用故事联想记忆法、规律记忆法、口诀记忆法与正方形图形记忆法,能促进学生对识记知识的加工与内化,提高记忆的主动性与趣味性,增强记忆准确性与持久性,能较好地巩固学习效果.

In the course of physical chemistry,the concepts of the characteristic functions and characteristic variables,the basic equations of thermodynamics and Maxwell’s relations are the key teaching contents of chemical thermodynamics.Persistent and accurate memorization of the above func-tional relationships and their important formulas is the basis and prerequisite for understanding and mastering the above-mentioned core knowledge of thermodynamics.However,students often have great difficulties in remembering these contents.Recognizing these knowledge points has become a difficult point in teaching.Teaching practice has proved that the use of story association memory method,pat-tern memory method,mnemonic memory method and square graphic memory method can promote the processing and internalization of students’knowledge,improve the initiative and interest of memory,and enhance memory accuracy and durability,thus consolidating the learning effect.
