Design And Implementation Of The Knowledge Base And Curriculum Planning In Intelligent Tutoring System

Intelligent tutoring is a related to artificial intelligence, computer science, cognitive science, psychology and pedagogy of the comprehensive subject, its goal is the research of computer simulation of excellent teachers teaching behavior and achieves the best teaching. Intelligent tutoring for the reduction of education and training costs, it is important to improve the quality of teaching, in the primary education, secondary education and higher education teaching intelligent have broad application prospects.The domain knowledge base and instruction scheduling is the core content of intelligent tutoring system, this paper has conducted the research to the knowledge base and course schedule. In the knowledge base, a framework for the representation of descriptive knowledge, using semantic network representation of relationship between knowledge, rule representation process knowledge, realize the technology to solve the intelligent tutoring system in many kinds of knowledge representation method, the knowledge expression ability; multi knowledge package and two level index the organizational knowledge base, the knowledge base is easy to extend, maintain, modify and query; at the same time, separate the organization of knowledge management and knowledge mechanism, processing mechanism of knowledge base access through the interface, so that the content of knowledge base organization mode change does not lead to changes in processing large institutions. In the part of curriculum planning, this paper presents implementation method of adaptive teaching plan, by automatically selecting knowledge unit, automatic arrangement on the order, according to the students’responses to automatically adjust the teaching sequence, make the teaching behavior has more adaptability and pertinence.According to the explanation to the same unit of knowledge from different angles can satisfy the needs of different students need, this paper puts forward the teaching method of operation, with a teaching operation corresponds to an explanation of the view of knowledge unit, teaching through activation of different teaching operation, make the teaching mode diversification. For the realization of reasoning in the process of teaching, this paper puts forward reasoning rules, the inference engine design, the input of different knowledge rules can make reasoning corresponding operation.
