Research On The Influence Of Interactive Teaching Video Based On Feedback On Learning Effect

In the information age.teaching video is the foundation of online courses.Therefore,the quality of teaching videos is the key to achieving quality education.How to improve the quality of teaching videos is the key to current research,and the development of interactive teaching videos provides it.Through the analysis of online courses,this paper finds that there are many kinds of teaching videos.Most of the interactive functions in the existing teaching videos only stay in simple interaction modes,such as playing,pausing,navigation,etc.,embedding problems and feedback interactive videos in teaching videos.There are not many articles in the existing literature,and there are not many articles on feedback-based interactive teaching video research.There is a lack of research on specific elements of feedback.Therefore,from the perspective of feedback,the specific elements of feedback are added to the video.Through experiments,the content and time of feedback in interactive teaching videos are studied,experiments are carried out.and conclusions are drawn,so as to provide reference opinions for the production of teaching videos.Taking MOOC net as an example,this paper studies and analyzes 120 courses of various disciplines,summarizes the interaction imodes in the existing teaching videos,and provides experimental data for the interaction design experiment proposed in this paper.On this basis,eye movement test and cognitive behavior experiment were used.Through three experiments,this paper explores the effects of different feedback contents in interactive teaching video on learning effect,cognitive load and learning satisfaction in declarative knowledge and procedural knowledge.respectively.There are four kinds of feedback:no feedback,correct result feedback,result correct feedback and fine feedback.The feedback time is divided into real-time feedback and delayed feedback.Through the experimental study of eye movement,the following conclusions are drawn:(1)Among different knowledge types,embedded feedback has the best learning effect;fine feedback has the best learning effect,and no feedback is the worst,and there is no difference between the other two feedback contents.(2)in declarative knowledge,feedback content has no effect on cognitive load and learning satisfaction,but fine feedback can reduce the difficulty of perceptual materials and improve the degree of psychological effort.(3)in procedural knowledge,feedback content has an impact on learning satisfaction,fine feedback can reduce the difficulty of perceptual materials and increase learning satisfaction.(4)feedback time has an effect on learning effect,immediate feedback improves learning effect.feedback time has no effect on cognitive load and learning satisfaction.Through the experimental conclusion of this paper,adding fine feedback to interactive teaching video production and presenting the answer in time will get a better learning experience.At the same time,because of the experimental conditions and other factors,there are still some shortcomings,in order to improve the follow-up experiment.
