Abstract

BACKGROUND

The COVID-19 pandemic interfered with normal campus life, resulting in the need for the course to be conducted in an ideal online format. The purpose of this study is to analyze the impact of different styles of online political course videos on students' attention during the COVID-19 pandemic.

METHODS

Four college students participated in this small sample study. They were required to conduct two sessions of the experiment, in which they were required to watch three different styles of course videos in each session. While watching the videos, their EEG signals were acquired. For the acquired EEG signals, the sample entropy (SampEn) features were extracted. On the other hand, Mayer's theories of multimedia technology provide guidance for teachers' online courses to enhance students' attention levels. The results of EEG signals analysis and Mayer's theories of multimedia technology were combined to compare and analyze the effects of three styles of instructional videos.

RESULTS

Based on comparisons of the SampEn and Mayer's theories of multimedia technology analysis, the results suggest that online instruction in a style where the instructor and content appear on the screen at the same time and the instructor points out the location of the content as it is explained is more likely to elicit higher levels of students' attention.

CONCLUSIONS

During the COVID-19 pandemic, online instructional methods have an impact on students' classroom attention. It is essential for teachers to design online instructional methods based on students' classroom attention levels and some multimedia instructional techniques to improve students' learning efficiency.

摘要

背景

新冠疫情干扰了正常的校园生活，导致课程需要以理想的在线形式进行。本研究旨在分析不同风格的线上政治课程视频对新冠疫情期间学生注意力的影响。

方法

四名大学生参与了这项小样本研究。他们被要求进行两次实验，每次实验都需要观看三种不同风格的课程视频。在观看视频的同时，采集他们的脑电信号。对于采集到的脑电信号，提取样本熵（SampEn）特征。另一方面，梅耶的多媒体技术理论为教师的在线课程提供了指导，以提高学生的注意力水平。将脑电信号分析的结果与梅耶的多媒体技术理论相结合，对三种教学视频风格的效果进行比较和分析。

结果

基于对 SampEn 和梅耶多媒体技术理论分析的比较，结果表明，在同时在屏幕上显示教师和内容、教师在讲解内容时指出位置的在线教学风格中，更有可能引起学生更高的注意力。

结论

在新冠疫情期间，在线教学方法对学生的课堂注意力有影响。教师根据学生的课堂注意力水平和一些多媒体教学技术设计在线教学方法，以提高学生的学习效率是很有必要的。
