摘　　要：利用超星“学习通”在线教学平台,开展物理化学线上线下混合式教学。以“自发过程的共同特征到熵增原理”的混合式教学为例,介绍了该模式的设计与实施过程。采用讨论式、翻转课堂等教学活动引导学生从热力学第二定律提出的背景出发,归纳总结出熵增原理,强调了自发过程的共同特征和卡诺定理对熵的提出及熵增原理的重要作用。将家国情怀与知识传授有机结合,突破了熵概念、克劳修斯不等式和熵增原理难点知识,培养了学生从实践经验出发进行归纳总结形成理论的科学研究方法。为物理化学混合式教学提供了教学案例。Based on the Superstar learning platform,the online and offline blended teaching mode of physical chemistry was carried out.Taking the blended teaching approach of“the common characteristics of spontaneous processes to the principle of entropy increase”as an example,the design and practice process of this model were introduced.Using teaching activities such as discussion and flipped classroom to guide students to summarize and deduce the principle of entropy increase from the background of the second law of thermodynamics.This paper emphasized the common characteristics of spontaneous processes and the important role of Carnot's contribution to the proposing entropy and the principle of entropy increase.On this basis,the aim of patriotic education and knowledge transmission could be achieved,the difficult knowledges such as the concept of entropy,Clausius inequality and entropy increase principle were overcomed.Finally the scientific research methods for students to summarize and form theories based on practical experience could be cultivated.This paper provided a teaching case for blended teaching of physical chemistry.
