CSCL Knowledge Constructing System Based On Agent Technology

Nowadays globalization of economic causes globalization of competition,lifelong learning education is precondition of national development and ofindividual development also. In western society thoughts of lifelong education,study organization, learning society has been accepted by common people.Lifelong learning is necessary for social development, and educational systembased on remote education which covers every town and village will supplymultilayer and diversification educative service for every social member. Thespecialty of popularity and lifelong style and social sharing is important forChinese society. Remote education treat open and flexible and lifelong educationas its goal, it developed from traditional education type and made a greatdevelopment. Computer Supported Collaborative learning is a new aspect ofremote education, it combines remote education form and collaborative learningform which will improve people's individual working ability and ability forteamwork. So Computer Supported Collaborative learning will strongly bedeveloped in remote education in future.In this paper a constructive model and working process of CSCL KnowledgeConstructing System based on agent technology have been proposed. Computermediated communication is not as perfect as Face-to-face communication, whichcauses some problem, such as it can not made a deep-level knowledge, low reusequotiety, and difficulty of making steady communication group. This system usesknowledge feature vector as a measure of cooperative candidates, and help theuser finds the most useful knowledge.Knowledge building system modeled cooperative knowledge constructing.The Agent system which made up of facilitator agents and user agents picks upand analyzes the characteristic of knowledge. The constructing process wasdivided into four parts. They are sharing, reasoning, negotiating, creation.Facilitator agent gets the knowledge link from the user agent, and decidecandidate agent suitable for next level knowledge constructing. The result ofsimulation experiments have showed that the system causes positive effect in theprocess of knowledge construction.
