Development And Application Of Micro Video In Physics Experiment In Junior Middle School

With the development of society,our learning beliefs,learning styles and learning habits are quietly changing.Learning is no longer limited to textbook paper,electronic materials and media video is also a way for people to learn.In the era of knowledge economy,lifelong learning has become a consensus,people will also seize the use of trivial time to learn,subway.On the public transport,watching learning products has become a trend.With the advancement of national education informatization,a large number of teachers in the development of better areas have begun to try self-taught experimental video,but also carried out related research.Based on the above background,this study revolves around the core problem of how to apply technology to developing and using physics micro-video in junior middle School from the following 3 aspects:1.Theory of exploiting video: What are the theories in video design theory that are suitable to guide the physical micro-video design? What technologies can support the video production? What is the mainstream guidance of developing physics experiment micro-video?What are the criteria that satisfying the psychological needs and visual aesthetics of junior school student?2.Model of video production: What process-model does video production conform to? What are the development paths and steps?3.The usefulness and effect of video: What is the application of video in the classroom and the teaching effect? What skills can be promoted for middle school students?Around these three aspects of research content,this search look for the relevant theoretical basis and modern technology,and developed four fields of junior high school physics experiment micro-video that includes force,heat,light and electricity.The application effect of the microvideo was tested by the experimental study of the pre-and post-group measurement.Through the analysis of the research cases,it is found that the development of physics experiment micro-video needs to go through the three processes of design,shooting and editing,and we need to consider the experimental content,scene,script,experimental materials,shooting site,camera hardware,review,title design,film tail design,dubbing and subtitles a total of 11 links in these three processes.The development of physics experiment micro-video is a tedious activity.With the help of teaching experiment,this study found that junior high school students use physics experiment micro-video to preview the effect is better than reading text;the teaching effect of using physical experiment video is better than that of demonstration experiment which is not easy to be seen by the whole class;Compared with the written hands-on production,the data students prefer video-based hands-on production guidance.
