现场授课与网络授课的知识传播效果差异及影响机制

Effect Differences of Knowledge Dissemination Between On-site and Online Teaching

基于某一流学科建设高校2019级、2020级共1630个本科生样本,实证分析现场授课与网络授课两种授课方式造成的知识传播效果差异,以及网络授课效果的影响机制。研究发现,给定匹配样本其他特征相似的前提下,网络授课学生的卷面成绩显著低于现场授课学生;除了教学软环境特征和受教育者个人特征外,课程交互性是影响网络授课效果的重要原因,相比于完全无交互,教师通过音视频向学生直播教学、提升与学生互动的强度,均能显著提升网络授课的教学效果。基于实证结论,提出应审慎地在大学本科教育中推广网络教育模式、在网络教育试点试验过程中应注意试点群体的选择、网络授课应更加重视师生互动等建议。

Based on 1630 undergraduate samples from a university in 2019 and 2020,this paper empirically analyzes effect differences of knowledge dissemination between on-site and online teaching,as well as the influencing mechanism of online teaching effect.Given the matching sample with similar other characteristics,the result show that the test scores of online students are significantly lower than those of on-site students.In addition to being influenced by the characteristics of the teaching atmosphere and the individual characteristics of students,the interaction of the course is an important reason for the effect of online teaching.Compared with no interaction at all,teachers can significantly improve the teaching effect by broadcasting live teaching to students through audio,video,or enhancing the intensity of interaction with students.This study put forward some suggestions based on the research results.The online education mode is supposed to be promoted prudently in the undergraduate education.Moreover,much attention should be paid to sample selection as well as the interaction between teacher and students when carrying out the pilot experiment of online education.
