Research On The Influence Of Teacher's Presentation Based On Eye Tracking Technology On MOOC Video Teaching Effect

With the rapid development of information technology,the advancement of digital education resources provides a rich choice for learning needs at all stages.Internet-based learning has gradually become an important way for learners to acquire knowledge.Online learning breaks through the limitations of classroom teaching in the choice of learners'learning time and the necessary geographical location for learning.It impacts the habitual behavior of learners to acquire knowledge,and more directly reflects the learner's leading role in the learning closed loop.effect.As a result,it has also brought new teaching ideas and theoretical practices to educators.In the past 10 years,the new learning process provided by the MOOC platform and the teaching methods of different subjects have been in the world with the advantages of large scale,excellent open attributes,scientific leading teaching mode and a large number of free high-quality learning materials.Widespread dissemination within the scope,and the impact of the new learning process and teaching ideas brought by MOOC on the upcoming educational changes is also the general trend.With the rapid development of the MOOC online education platform,researchers in related fields such as education are paying more and more attention to the learning effects of MOOC.Teaching media video is one of the important ways for learners to acquire knowledge on the MOOC platform.It is an important channel for teaching content communication.It is an important channel for learning users to obtain knowledge information when they are learning online.Its level will directly affect MOOC learners'courses.Participation and learning outcomes.In recent years,experts and scholars in the field of education have also begun to use eye trackers to track and record the visual behavior of learners in the learning process.Using eye tracker to track and record the eye movements of learners,the learners' behaviors throughout the learning process can be efficiently and accurately understood.Eye tracking technology can more accurately examine learners' learning behaviors during online learning than other traditional methods.At present,the research on the effect of video teaching focuses more on the characteristics of the video course itself,and pays little attention to the subject of teachers in video teaching.As the main body of teaching activities,teachers'behaviors will affect the learning effect of learners.Supported by eye tracking technology,this paper deeply explores the influence of different presentation forms of teachers on the teaching video of declarative knowledge and procedural knowledge,which has three effects on learners' attention,cognitive load and academic achievement.Can provide a basis for the development of online learning videos.The research results show that the guiding effect brought by the teacher's presentation helps the learner's attention distribution in the MOOC video learning process,and the learner's psychological effort level is improved without increasing the learner's mental load level.Finally,the teacher's large window presentation effectively improves the learning effect of the learner's declarative knowledge.
