基于“SPOC+慕课堂+腾讯会议+微信群”的在线教学实践——以仪器分析课程为例

doi:10.3866/PKU.DXHX202005059

Abstract

Abstract:

Online teaching has been adopted by colleges and universities during the coronavirus disease outbreak. The problem for teachers and students is how to turn this crisis into an opportunity. Furthermore, it is important to ensure the quality of online teaching and explore new ways of teaching and learning. Therefore, a new form of online teaching of instrumental analysis course was developed using the combination of "SPOC + MOOC class + Tencent meeting + WeChat group." The practice of this new form of online teaching, that is, before class (guiding and helping), during class (teaching and studying), and after class (thinking and testing), shows a good teaching effect. In addition, it provides reference for online teaching.

Key words: Instrumental analysis, SPOC, MOOC class, Tencent meeting, WeChat group, On-line teaching
