Student Client Navigation Model Design In Intelligence Teaching System

CAI(Computer Assisted Instruction) is one of the very important application of computer technology. It requires that CAI develop to a network based, intelligent system with the development of modern education deepened.ICAI is an intelligent CAI(Computer Assisted Instruction) system, which is the combination of the AI and CAI. It has several parts: the knowledge-base, the course maker, the deducing machine, the management tools, and the study guiding interface.There are three intelligent bodies In ICAI system: teacher, student and deducing machine. In the student model, an important part is the intelligent knowledge-node net navigation map, which is also called the navigating education environment on web. The students can master the first and the next knowledge node of this one by the net navigation map. So that students can master the knowledge more systematically.This paper discusses the development of the navigating education environment on web and the construction of the intelligent knowledge-node net navigation map in detail. This paper also analyses the design and implement of the intelligent knowledge-node net navigation map and concentrates on several issues in detail.
