基于学习通平台的混合式教学在物理化学实验中的实践

Practice of Blended Teaching in Physical Chemistry Experiment Based on Xuexitong Platform

摘要: 依托“学习通”平台，结合物理化学实验课的特点和以往教学经验中存在的问题，探索并实践了线上线下混合教学新模式。该模式以“学生为中心”重构教学流程：课前，学生可根据个性化需求，自主安排时间、掌控线上预习节奏；课堂内师生互动、生生互动时间增加，学生以小组合作方式完成实验，主体地位凸显；课后，学生参与线上拓展阅读、在线讨论与反思，在延伸的学习时空中继续完成对知识的内化，过程性数据全程可记录、可量化、可追溯，实现过程评价与终结评价有机结合。结果表明，学生学习主动性、积极性显著提高，实验操作更规范、熟练，教学效果大幅提升。

Abstract: Based on the Xuexitong Learn platform and taking into account the characteristics of physical chemistry experiment courses and the problems encountered in previous teaching, we developed and implemented a new online-offline blended learning model. This student-centered approach restructured the teaching process. Before class, students arranged their own schedules and controlled the pace of online preview according to individual needs. During class, student-teacher and peer interactions were enhanced; students conducted experiments in collaborative groups, and their leading role was foregrounded. After class, they consolidated knowledge through online extended reading, discussion, and reflection in an extended learning environment. Learning-process data were recorded, quantified, and traceable throughout, integrating formative and summative assessment seamlessly. The results indicated that students’ learning initiative and enthusiasm increased significantly, their experimental operations became more standardized and proficient, and the overall teaching effectiveness improved substantially.
