课堂视听-交互距离的线上与线下教学效果对比分析与对策——以小学期通识课程“遥感中国”为例

Comparative analysis and countermeasures of online and offline teaching effects of classroom audiovisual interactive distance——Take the general education course Remote Sensing China as an example

新冠疫情的爆发对全球教育系统带来了巨大影响,线上教学的形式已广泛应用于各类教学活动,然而教学的效果却受到了诸多因素的影响.本研究旨在通过问卷调查与学生成绩对比,分析同一课程线上与线下教学形式的教学效果差异.结果表明:线上教学地点灵活、授课容量大和近距离视听等优势,对于图像、视频等可视化教学内容丰富的通识课程来说教学效果较优,具有普适性;线上良好的视听距离使得听课效率普遍提升,成绩与线下相比更为优秀;师生交互距离变化对于学习自制力不强的学生来说,成绩会更不理想.本文对线上教学或线上与线下混合式教学的教学策略制定提供参考.

The outbreak of the COVID-19epidemic has had a tremendous impact on the global education system.Online teaching has been widely used in various teaching activities,but the effect of teaching has been affected by many factors.The purpose of this study is to analyze the differences between online and offline teaching forms of the same curriculum through questionnaire survey and comparison of students’achievements.The results show that online teaching has the advantages of flexible location,large teaching capacity and close audio-visual,and the teaching effect is better for general education courses with rich visual teaching contents such as images and videos,which is universal.The good online audio-visual distance has generally improved the efficiency of listening,and the performance is better than offline.The change of teacher-student interaction distance will be even worse for students with weak learning self-control.This paper provides a reference for the formulation of teaching strategies for online teaching or online and offline hybrid teaching under the background of epidemic normalization.
