基于眼动追踪技术的教师呈现形式对视频教学效果影响的研究

Research on the Influence of Teacher Presentation Form on Video Teaching Effect Based on Eye Movement Tracking Technology

目前,绝大部分在线课程都是以视频的形式呈现。教师作为教学活动的主体,在课堂上的行为会对学习者的学习效果效果产生很大影响。但是目前教学视频的研究更多地集中在教学内容,而很少关注教师主体。本文对不同教师呈现形式的MOOC学习效果进行量化研究,其中对陈述性知识和程序性知识学习过程中被试的眼动数据进行分析,数据分析表明老师形象呈现所带来的指导效果有助于学习者更多的关注到视频教学的过程中去,同时在不增加学习者心里负荷水平的情况下使学习者的心理努力水平得到了提升,而且教师大窗口形式呈现能够有效地提高MOOC学习者陈述性知识的学习效果。该研究结果为MOOC在线学习的教学视频方案设计提供了一定的参考。

Currently, the vast majority of online courses are presented in the form of video. As the main body of teaching activities, the teacher’s behavior in class will have a great impact on the learning effect of learners. But at present, the research of instructional video focuses more on the teaching content and less on the teacher subject. This paper conducts a quantitative study on the learning effect of MOOC in different forms presented by teachers, including an analysis of the eye movement data of the subjects in the process of declarative knowledge and procedural knowledge learning. The data analysis shows that the guidance effect brought by teacher image presentation helps learners pay more attention to the process of video teaching. At the same time, the level of mental effort of learners is improved without increasing the level of mental load of learners, and the presentation of teacher’s large window form can effectively improve the learning effect of declarative knowledge of MOOC learners. The results of this study provide some references for the design of instructional video programs for MOOC online learning.
