“线上线下相结合”有机化学实验教学模式的建立与实践

Establishment and Practice of an“Online and Offline Combined”Teaching Mode for Organic Chemistry Experiments

该文将传统有机化学实验课程与新形势下线上信息化教学手段紧密结合,建立贯穿课前预习、课中操作、课后总结3个阶段,以学生为主体的“线上线下相结合”有机化学实验教学新模式。并提出侧重参与度考核权重(参与度考核成绩来源于教师评分、平台统计分和生生互评)的多角度、多元化考核评分体系。以“肉桂酸的制备”实验为例,学生初次尝试线上线下相结合的实践类课堂,教师通过设置“课程任务”的方式调动了学生学习的积极性和主动性,最终得到良好教学效果,进一步推动高等院校化学类实验课程的改革。

This paper closely combines the traditional organic chemistry experiment course with the online information-based teaching methods,and establishes a new“online and offline combined”teaching model for organic chemistry experiments,which runs through the three stages of pre-class preview,in-class operation and after-class summary,with students as the main body.It also puts forward a multifaceted and diversified assessment system that focuses on the weight of participation(participation assessment results are composed of teachers’assessment,platform statistics and mutual assessment of students).For example,in the“preparation of cinnamic acid”experiment,students try the online and offline combined practical classes for the first time,where teachers mobilize students’learning enthusiasm and initiative by setting“course tasks”,and finally achieve good teaching results.This teaching mode will further promote the reform of chemistry experiment courses in colleges and universities.
