Design and Implementation of a Dual Master Computer Based Intelligent Tutoring System

In this paper, the double subject teaching model, teachers play the leading role and can fully reflect student's cognitive main role, more in line with the current situation of China's education development; historical inheritance of study of student model, allowing the system to an accurate assessment of students, the realization of the optimal teaching effect. In addition, this paper presents the concept tree to represent knowledge, which is not only convenient to check the redundancy of knowledge, but also is suitable for students to learn the automatic navigation, it is worth promoting. In the part of design, this paper combines domain knowledge representation method, is given a oriented cognitive object of hyper text knowledge representation method, put forward the rules of teaching strategy reasoning machine based on weighted; according to cognitive learning theory, a by successive approximation method of historical inheritance of study cognitive student model, which design a learning process automatic navigation and hypertext navigation teaching model based on the student model and knowledge presentation. It also discusses the intelligent system to explain the mechanism and man-machine interface design. In the part of realization, the realization of writing environment and man-machine interface, discusses the organization and management of knowledge, gives the reasoning of concrete realization of the code and try to give a intelligent tutoring system model of the initial implementation in the last part of this paper, the prospect of the development of the system are discussed.
