| As an important means of Modern Distance Education, video teaching has developed for several years and its resources became rich and diverse. Using micro-video resources to promote web-based instruction is attached great importance to Modern Distance Education, such as the khan academy, flipped classroom, network open class and MOOCs etc. As learning becomes mobile, miniaturized and fragmented, how to develop the distance education based on micro-videos, which in an environment full of network resources and there are some web-based learning management systems; how to guide Modern Distance Education towards interactivity and convenience; how to exploit advantages of micro-video resources to the full, these will be the new issues to the study of Modern Distance Education.First, the author based on the Instructional Design and Instructional Interaction Theory, and makes the learning of<Distance Educations as an example. The chapter was divided into some little teaching knowledge unites, and each unit was showed in the way of dramatized, contextual text form. Next, according to the content of the manuscripts, the author used Flash animation software to create a micro-video animation combined with images, texts, sounds and videos. Drawing tools and PowerPoint2010are main editing tools we used in this design. The presentation time is3to5minutes. Finally, converting SWF format animation to FLV video streaming media format. Streaming video has some advantages such as low CPU occupancy, good video quality, and small size, suitable for network playback. And it is also applied to mobile phones, PDA and other mobile terminal video playback to satisfy the distance learners that are not restricted by time and space of learning.To explore the effect of micro-videos applications in the network teaching and teaching effectiveness based on interactive forums, testing, operation of various types of interactive activities, the paper designed a questionnaire which includes three levels of Instructional Interaction, which is Operational Interaction, Informational Interaction and Conception Interaction. According to study findings, network teaching platform records and student interviews, we did some statistical analysis. Through these analysis, we found that there are some problems, such as "use platform meet obstacles will affect the learning process","micro-videos in understanding and deepen the knowledge is not very good","Animation is monotonous, video seen that will be forgotten", some countermeasures were proposed which aims to solve these problems: do some technical trainings before distance learning to enhance the efficiency of interaction between students and the media interface, use small quantity and good quality micro-videos to enhance the efficiency of interaction between students and learning resources; use a variety of interactive tools and other resource materials to enhance the efficiency of interaction between students and students, students and teachers. And the last one is emphasis on teaching interaction design to ensure that the old and new concepts of student interaction can occur.The innovation of this paper is based on the Interactive Teaching Level Tower Theory of Chen Li’s, making instructional interaction design based on three levels of Operational Interaction, Informational Interaction and Conception Interaction, and applying it to the distance teaching practice. Meanwhile, in terms of the production methods and expression forms of micro-video teaching resources, this paper puts forward the specific and operational methods. This study hopes to provide help for the development and application of micro-videos in distance education. |
