With the development of modern information technology and the advent of the era of fragmented learning, micro video teaching which was applied to high school biology teaching is gradually recognized. Students are also eager to learn micro video. However, there are a large number of problems during developed micro video sources nowadays, such as video design tended to ignore technical, artistic, etc. Therefore, the author put forward discussion on the optimization of high school biology teaching micro video production.This paper takes cognitive load theory, multimedia art theory, micro-learning theory,audio-visual educational theory as theoretical guidance, combined with high school biology knowledge,combing the importance of micro video resources for students learning, and analyse how to reduce the learners’ extraneous cognitive load and improve the related cognitive load in micro video production. Accordingly, the author proposed the main principles of micro video production, including the developmental principle, scientific principle, the principle of multi-channel, artistic principle, principle of proximity, etc. Through the analysis of the evaluation standard of China’s micro class competition, as well as related research of other scholars, this paper pointed out that the use of a micro video index evaluation system for the topic, instructional design, media design, and thus be the case of creation.Micro video production had a variety of forms and applications also had a variety of patterns,the author defined the biology teaching micro video in this paper as the video applied to preview the lesson,and carried on a creative practice by taking’’ Energy supply and utilization of cells”for example. For the convenience of micro video resources development for biology teacher, the author used PowerPoint 2013, Camtasia Studio 8 and After Effects CC. Finally, the author applied the micro video resources in the high school biology teaching practice, analysed the experimental results, proved that micro video resources produced by the author got preliminary optimization. |
