【中文摘要】:

通过眼动追踪技术和脑机交互技术可对MOOC视频进行量化过程分析。文章通过眼动实验和脑电实验跟踪测量了46位被试在两种不同组织方式的实践型MOOC教学视频中的学习过程,从测验成绩、认知负荷和专注度三个方面对学习效果进行量化分析。针对本实验案例准备的视频材料,研究结果表明:眼动数据和脑电数据同学习者的学习效果存在关联关系(注视次数同学习材料的理解难度呈正相关,注视时间同认知负荷呈负相关,专注度同注意力呈正相关);视频组织方式同学习者的学习效果存在关联关系,对于概念定义类知识,Group A的MOOC视频设计学习效果更好;对于实践操作类知识,Group B的MOOC视频设计学习效果更好。在此实验结果的基础上,从教学内容、画面结构、学习者心理等维度对MOOC视频的设计提出了建议。


【英文摘要】:

Eye-tracking technology and brain-computer interaction technology can be used to analyze MOOC video quantitatively. In this study, the learning process of 46 subjects is measured through eye movement experiment and EEG experiment in two different modes of organization of MOOC teaching video, and then the learning effect is analyzed qualitatively from three aspects: test scores, cognitive load and concentration. The results show that there is correlation between the data of eye movement and EEG and learners' learning effect(The number of fixation is positively correlated with the difficulty of learning materials;fixation time is negatively correlated with cognitive load; and concentration is positively correlated with attention).There is a correlation between learners' learning effect and the organization mode of videos: for the concept knowledge, the learning effect of group A is better;while for the practical knowledge, the result of group B is better. Finally, some suggestions are put forward for the design of MOOC videos from teaching content, picture structure, learner' s psychology etc.
