Primary Mathematics Web-based Intelligent Tutoring System

Intelligent computer assisted instruction is the certain developing trend of human social digitalized education. In this paper , we combine the HTML advantage with ICAI characteristic, use ASP.net technology to realize a web-based intelligent instruction system, which assists mathematical learning in primary school.The system is designed on the base of cognitive learning theory and constructivism learning theory. It includes knowledge database , student module, teaching module, Web-based forum and so on. In the knowledge representation, the relation of each meta knowledge node is described by the relation network graph of triangle knowledge, It is a Directed Acycline Graph with weight. Node represents the meta knowledge node, the beeline represents the support degree of meta knowledge nodes. Each knowledge node has certain basic attribute. In data graph, One record describes the attribute of one knowledge node and one study material (tiny teaching unit) at least, one tiny teaching unit and a beeline of the relation network in the meta knowledge node database.Learners can search out the study material hype-link from the database according to the meta knowledge node identifier. He can learn the new knowledge, do the related exercises in this system. The general process of study follows these steps: Review the related knowledge at first, next study the example of the meta knowledge node, then do the exercise. If he meets questions , he can ask for the help of other students or teachers by the network. After he finished learning, he can have a test, to make his cognitive student model. If he have studied all the meta knowledge node of triangle, he can have a synthesize test. The paper describes a trial of the system done by the students of the grade four, the result of the experiment. The result shows that the system can intelligently guide the exploring learning of the students.
