摘要：

计算化学实验是以分子模拟为工具，通过“实验、计算、理论”协同作用来解决各种核心化学问题的实验课程。在新冠疫情防控常态化的大背景下，为提高计算化学实验课程的教学质量，我们基于本课程组前期的教学论文，结合本校的教学实践，对计算化学实验课程进行了教学改革实践。重新设计和整合教学资源，录制了实验讲座的微视频，对课前、课中和课后三个阶段的学习内容进行设计，并依托超星学习通平台构建了“计算化学实验”网络课程。教学实践表明，通过将传统课堂教学与线上教学混合教学模式的实施，实现了从“教师讲授为主”向“学生自主学习为主”的模式转变，从而提高学生运用结构化学的原理和方法来分析、解决问题的能力，培养学生探索未知、追求真理、勇攀科学高峰的责任感和使命感。我们的教学改革实践取得了良好的教学效果，也为高校教学改革提供一些参考。

Abstract:

Computational chemistry laboratory is a laboratory course that uses molecular simulation as a tool to solve various core chemical problems through the synergy of "experiment, calculation and theory". In order to improve the teaching quality of computational chemistry laboratory course, the teaching reform of computational chemistry laboratory course are carried out against the backdrop of COVID-19 prevention. Based on the previous teaching papers of our course group and the teaching practice of our school, we have redesigned and integrated teaching resources, recorded micro-videos of laboratory lectures, designed the pre-class, in-class and after-class learning contents, and constructed an online course of computational chemistry laboratory using Chaoxing Learning Platform. The teaching practice has showed that the mixed mode is beneficial to the mode transformation from "teacher-oriented" to "student-oriented". It also can improve the students' ability to analyze and solve problems by using the principles and methods of structural chemistry, and cultivate students' sense of responsibility and mission to explore the unknown, pursue the truth, and climb the heights of science. Our teaching reform practices not only have good teaching effects, but also provide some references for the teaching reform in university.
