| Abstract: | The improved genetic algorithms with decision tree and its application are adopted to analyze and classify the learner＇s knowledge state, style of learning, history of learning and cognitive ability. The student model can be divided into four categories, i. e. deviation model, coverage model, mental model and cognitive model,which can provide a personalized learning circumstance for learners. |
