Research On The Effect Of Barrage Video Learning And Its Influencing Factors

In recent years,the barrage video as a new form of video has gradually attracted the attention of online education researchers.The research intends to simulate the video of barrage video to discusses the learning effect of the danmaku video and its influencing factors.In study one,this research discusses the learning effect of the danmaku video compared to with the normal video.Then,this research tries to explore the effect of danmaku video from the content of the danmaku information,including the experiment 2A(information group-independent information group)and experimental 2B(direct information group-indirect information group).In study three,this research discusses the presentation of danmaku video by using 3(danmaku loction:upper,middle and lower)X 3(danmaku speed:fast,medium,slow)two factors design.In the experiment,the method of simulating the danmaku video is used to produce the danmaku video with different content and presentation.All of study used the typical multimedia learning program.The effect of learning is based on recognition and recall.Results show:①The danmaku video is better than the normal video of the learning effect;②When the danmaku is related to learning content,danmaku will promote learning,mainly reflected on the recall performance;③When the danmaku is irrelevant information,compared with the normal video,there is no difference on learning effect;④The presentation of danmaku(location X speed)will affect the danmaku video learning effect;⑤Danmaku does not affect cognitive load.The following conclusions can be drawn from experimental research:1,barrage play a role in promoting video learning.2,the impact of barrage video learning factors,including barrage information content and presentation(speed and location).3,barrage has little influence on cognitive load during video learning.
