Research On The Influence Of MOOC Video Presentation On Learning Effect

With the rapid development of the Internet,MOOC(Massive Online Open Course),as a new online learning mode,can impart knowledge by presenting visual information.Researchers believe that MOOC can attract learners' attention and deepen their understanding of knowledge.Therefore,the learning effect of MOOC video has attracted the attention of researchers.From the perspective of human factors engineering,the author believes that social presence,learning satisfaction and cognitive load are important factors affecting learning effect.However,most of the research on the effect of video presentation on the learning effect was tested by questionnaire survey,which paid little attention to the factors that could best reflect learners' visual and cognitive psychological.Based on the perspective of human factor engineering,this paper uses questionnaire survey and eye tracking to record and collate the visual and psychological factors in the learning process of learners,so as to evaluate the best way of video presentation,in order to provide a suggestion for the MOOC video production team.Firstly,this paper studies the classification of teaching video presentation methods by literature research method,and classifies the presentation mode of video courses on the platform of MOOC online education in China University.Three presentation modes("PPT Video + teacher image","PPT Video + teacher image + subtitle","PPT video")are summarized as the research object of this paper by ABC classification.Secondly,four factors that influence the effect of video learning are determined by literature research methods,namely social presence,cognitive load,learning satisfaction and learning achievement.According to the four affecting factors,the MOOC video learning effectiveness evaluation index system was established,and based on the evaluation index system,a questionnaire survey and eye movement experiment were designed to obtain the social presence degree,learning satisfaction,learning achievement and cognitive load of the three presentation modes of video.And the size of the cognitive load and the visual information of the learner and the data of the cognitive processing process,and establish a structural equation model to explore the relationship between the four influencing factors and the learning effect,and analyze the relationship between each factor and the learning effect.The interaction relationship evaluates the best video presentation method.By analyzing and comparing the results of video learning of three presentation modes,"PPT Video + teacher image + subtitle" is the best presentation modes,in which social presence and learning satisfaction can promote learning effect,while cognitive load will affect the learning effect.
