“高分子材料合成创新实验”线上教学探索与实践

doi:10.3866/PKU.DXHX202004074

Abstract

Abstract:

Based on the platform of "QQ share screen + video live broadcast", through the combination of "online theory teaching", "development of home alternative experiment", "game type" experimental operation and "virtual simulation experiment", we carried out the online teaching of polymer material synthesis innovation laboratories, integrating "theory + practice" and "virtual + reality", which is also a good opportunity for labor education. These explorations and practices are expected to provide some references for online teaching of chemical laboratory courses during the COVID-19 epidemic.

Key words: Online laboratory teaching, Stay home alternative experiment, Labor education, Virtual simulation, Knowledge relevance
