Research On Member Trust Evaluation And The Agorithm For Partner Selection In Cooperative Learning

With the rapid development of network technology, Computer-supported Cooperative Work(CSCW) achieves widespread application. Computer-supported Cooperative Learning (CSCL) is thedevelopment application in education sector of the CSCW technology, which currently is aninterdisciplinary hot spot of modern educational technology and computer science. CSCL supports theinteraction between cooperative learning partners through computer networks, with the environmentof web for cooperative learning members, it is very important to find appropriate learning partners forthe formation of excellent collaborative learning team, which can directly affect the learningefficiency in CSCL. However, cheating behavior appears inevitably in cooperative learning processbecause of the open network environment, which leads to the failure of collaborative learninginteractions. Therefore, it is necessary to research trust evaluation model for cooperative learningmembers.First, this thesis summarizes the status of trust evaluation research home and abroad and givesthe trust relationship model for cooperative learning members. A trust evaluation model is proposedfor cooperative learning members based on the historical interactions, and calculation algorithm aboutdirect trust and recommendation trust are integrated for trust computing.Then, this thesis defines and classifies e-learning member’s behaviour capability in cooperativelearning. In order to get stage achievement evaluation in cooperative learning, an algorithm isdesigned for measuring member’s behaviour capability according to the collaborative assessments incooperative learning process. By combining user trust and behaviour capability, a relevant evaluationmodel is proposed to support rational selection of cooperative learning partner.Finally, an architecture of cooperative learning partner selection system has been implementedfor supporting the formation of collaborative learning team. The main modules and message transfermechanism supporting communication between collaborative processes are presented. The results ofsimulation cases verify the feasibility and effectiveness of the trust evaluation model for cooperativelearning members.
