摘要
文章针对学生普遍反映的热力学第二定律难学的问题,介绍了作者多年积累的一些教学体会。文章指出:在教学热力学第二定律过程中,教师一定要做到教学思路清晰;将整个教学过程分个几个有内在联系的教学单元,第一单元都要向学生介绍清楚相关科学前辈是怎样提出问题、如何分析问题和解决问题的;当介绍到问题转折处,一定要提醒学生注意;重点介绍热力学第二定律及相关状态函数熵的物理意义,让学生树立起能量是分等级的这一重要观念;最后,让学生掌握用热力学第二定律判断宏观过程方向和限度的方法。
The paper was mainly talked about the difficultly learning question from students about the second law of thermodynamics,introduce some teaching thought for many years accumulation of author.The paper pointed out： in the teaching of the second law of thermodynamics,teacher must had a clear train of thought;the total teaching processing were separated several teaching units having inner relatives,the first unit was to clearly introduce to students that the relative senior scientist was how to put forward the question,how to analyze and solve the questions;when introducing the turnover of question,we must to rivet students＇ attention,mainly introduce the physical meaning of the second law of thermodynamics and relative state function entropy,let students construct the important concept of energy which is separated several grades;at last,let students master the methods to judge the direction and limit of macro-processing with the second law of thermodynamics.
