基于IIS图分析的媒体技术教学应用研究的个案分析

A Case Study on Instructional Application of Media Technology Based on IIS Map

It is much more appropriate to adopt the analysis method based on information flows because the instructional system is information system in nature. The analytical method based on IIS-map is a mature analytical method of instructional information flows. The instructional application of media technology based on IIS-map.is a new research approach. It focuses on proving the feasibility of the technology applied to achieve learning goals by the instructional information flows and the four characteristic indicators of a media technology product， such as quantity of activation， contribution of activation， contribution of media diversity and ratio of function utilization， instead of testing the instructional effectiveness of media technology by instructional comparative experiments. In this way， it can evaluate characterize the contribution and dependency of media technology for instruction. This paper preliminarily demonstrated that the research approach is feasible and the indicators is available. And it discovered that while analyzing the dependency of media technology we could not only consider the contribution of technology products， but also take the efficiency improvement and the convenience of instruction by the technology application into account in instructing. Besides， it has given us some enlightenments: the function requirements of teaching media should according to teaching practice rather than the intention of others; the development and function design of products should meet the learning activity; whether upgrade a function or not be determined by instructional application. This research approach can help people treat the teaching effect of technology rationally and break its teaching.
