Knowledge Points Organization Model based on AND/OR Graph in ICAI

The organization structure of knowledge points is the basis of teaching navigation in ICAI (Intelligent Computer Assisted Instruction), and it also determines the effectiveness of the intelligent reasoning in ICAI. The paper presents a Knowledge Points Organization Model based on AND/OR Graph. The introduction of AND/OR logic, makes the model can easily represent the selective knowledge points which is hard to represent in previous models. It also changes the teaching navigation path from the traversal of the entire knowledge structure graph to the traversal of various solution graphs of the entire graph.
