高时间利用率的《物理化学》习题解析模式的开发

Development of a High-Time Utilization Model for Solving Problems in “Physical Chemistry”

摘要: 基于理工科学生学习物理化学的同时还须兼顾几门其他专业课，导致其复习课堂知识的整块时间不足的情况，文章以天津大学主编的《物理化学》第六版的课后习题为依托，通过录制课后习题解析短视频的方式，增加课内知识点与课后习题中涉及知识点的关联性，进一步加强学生对课程知识的理解与复习，有效提高学生利用碎片化时间学习的效率。根据两届学生的试用结果，在每个章节增加一次小测验，能够大力提高学生利用视频复习知识点的积极性，进而深入掌握物理化学知识。

Abstract: As students have to learn physical chemistry together with other major courses at the same time, the time for reviewing in-class knowledge of physical chemistry is not sufficient. In the current work, the problem-solving videos of the typical after-class problems of the sixth edition of “Physical Chemistry” edited by Tianjin University are designed and recorded in a new mode. The video contents contain illustrations of after-class problem solutions and the correlation of in-class knowledge with after-class problems. Each video is short and aims to improve the fragmented time utilization of students and their learning efficiency. The application of these videos in course teaching showed that the set of one quiz after each chapter had been taught can facilitate the enthusiasm of students to review the course knowledge and help them to master the course knowledge.
