INTELLIGENT TUTORIAL PLANNING BASED ON KNOWLEDGE STRUCTURE GRAPH

Based on the concept of AND/OR graph,the concept of knowledge structure graph and the concept of tutorial plan graph are presented.By using a knowledge structure graph about a curriculum,the knowledge structure of the curriculum can be represented clearly and conveniently.The intelligent feature of the approach is that for different students different tutorial plans can be derived.Every tutorial plan is well suit to the individual student.Algorithms are given,which can be used to obtain optimal tutorial plan based on knowledge structure graph and a student’s knowledge level.The correctness of the algorithm is also proved.
