An Empirical Research on IIS-Map-Based Analysis Method of Instructional System

This paper argues that an instructional system is composed of IPT (information processing of teacher), IPLs (information processing of learners), IPM (information processing in media) and IIS (instructional information set). IPT, IPLs, IPM and IIS interacts through information flows which are named {X} and {Y}. To analyze such an instructional system ,we need to build IIS-map which is the result of knowledge modeling, to segment instruction video flow into input items which represent {Y} and calculate the quantity of attribute researchers interested. The activation is the most important attribute. The experiment shows that activation and learning effect of knowledge nodes have positive correlation.
