疫情下的仪器分析课程在线教学设计与探索——以绪论为例

doi:10.3866/PKU.DXHX202003037

Abstract

Abstract:

During the wide spread of new coronavirus pneumonia, how to use information technology for carrying out the effective online teaching is an important question and discussion among teachers and students. Instrumental Analysis is an important basic course for the college students majoring in chemistry. In the time when teachers and students can only "hear" or "meet" online, how do we ensure the quality of online teaching? Taking the introduction part as an example, the author presents the process and fruits of their efforts to achieve better teaching and learning quality.

Key words: Instrumental analysis, Online teaching and learning, Course ideology and politics, Diagnosis of new coronavirus pneumonia, O-AMAS
