摘要:

为应对新冠疫情对有机化学实验教学的影响,分析并讨论了传统有机化学实验教学中存在的局限性,并以正溴丁烷的制备实验为例,针对性地提出了一种“线上线下-虚实结合”的有机化学实验教学新模式:联合应用“腾讯会议→MLabs→实验室→微信群”等工具或场所建立了有机化学实验课程“教师课前线上导学→学生利用虚拟仿真平台预习和练习→师生实验室讨论与操作→课后综合考评与答疑”的教学新模式。经初步实践,发现对培养和提高学生的实践能力和创新能力有良好的效果,为“金课”背景下有机化学实验教学改革提供了参考。

Abstract:

In response to the impact of the Covid-19 epidemic on organic chemistry laboratory teaching, this article analyzes and discusses the current limitation of traditional organic chemistry laboratory teaching. Taking the "preparation of n-bromobutane" as an example, a new "online-offline and virtual-actual combination" teaching mode with the combination of "Tencent Meeting, MLabs, laboratory and WeChat group" is introduced. The practice of the new mode of teaching includes the following steps: pre-class online guiding by teacher, student preview and practice based on the virtual simulation platform, students and teacher discussion and operation in laboratory, and post-classcomprehensive assessment and Q&A", and good teaching effects have been received. It is significant in cultivating and improving the independent innovation and practical ability, and provides reference for the organic chemistry laboratory teaching reform and also lays a foundation for the construction of "outstanding course" of organic chemistry.

Key words: Organic chemistry laboratory, Virtual simulation experiment, On-line teaching, Off-line teaching, Tencent Meeting, WeChat group
