doi:10.3866/PKU.DXHX202111035

Abstract

Abstract:

Based on the establishment objective of comprehensive chemistry laboratory (Ⅰ) and the current laboratory teaching situations, the blended teaching model combining online teaching with offline teaching was put forward, in order to train talents in chemistry and improve students' comprehensive academic ability. The blended teaching pattern in the application of comprehensive chemistry laboratory was presented, taking "steady-state and time-resolved fluorescence spectrum experiment" as an example. In the teaching process, online video teaching, demonstration experiment and offline practical operation were combined, supplemented with other teaching methods such as oral presentation, symposium, etc., which would fully mobilize students' interest and enrich the teaching elements. The questionnaire showed that most students believed that the online and offline combined teaching model was very helpful and attractive.

Key words: Comprehensive chemistry laboratory, Online teaching, Teaching model, Laboratory teaching reform
