Roles And Cscl-based Intelligent Network Collaboration Model Study

The globalization of economy and popularization of social's information industry,especially the rapid development of computer network technology,provide people with more extensive territories and more cooperating opportunities. Colony scale is more larger ,and the scope is more extensive.In education area,people change their attention from tutorial study to colony collaborative learning.Then the study of CSCL(Compuer Supported Collaborative Learning) became flourish. Combining theories and methods of CSCW(Computer Support for Collaborative work)and CL(Collaborative Learning), it uses computer technology(multimedia and network) to assist and support collaborative learning. CSCL is a quite new distributed learning pattern.How to use modern network communicating technologies to build an effective virtual learning environment,becomes a new task in the face of people.The current studies about CSCL virtual learning environment focus on learning course programming , release , course management , learning material management.In the present studies,we lack technological scheme combining modern computer technologies and CSCL -supported environment.Intelligent agent is a kind of entity with autonomy and collaboration. By introducing agent technology into network learning, it privides more extensive spaces to development of network collaboration learning,and bring it into a quite new frield which is full of intelligence.In order to conquer deficiency of intelligence and individuation in existing CSCL systems,An intelligent network collaborative model based on role mechanism and CSCL is presented in this paper.In the paper,we study the application of role mechanism and intelligent agent technologies emphasizely.Fistly,we analyze the virtue and deficiency of a typical CSCL system named CODILESS ,and then proposed an intelligent network collaborative model based on role mechanismand CSCL.In the paper,the framework of the model is provided,applications of agent and role theory in the model are also presented;Role-based organization pattern and communication pattern are studied. By analysing collaborative learning process ,we present a a role-based colony collaboration mechanism,and a role-based multi-agent collaborative learing arithmetic.Role-basedcolony communication and cooperative rules are also provided; The model provides a new pattern to the network learning, perfectly embodies individual learning and promotes comprehensive collaboration among learners. Particularly ,the applicatin study of role mechanism in open dynamic net environment enrich the theories of MAS greatly. The paper's main innovation is:(1) detailedly states role theory and puts forward a role-based collaborative learning model from the view of multi-role,which supply a new pattern to CSCL virtual learning environment.(2) the application combination of role machanism and intelligent agent technology in our model ,will greatly improve agility and intelligence of collaborative learning system.(3) It proposes a role-based colony collaboration machanism and a role-based multi-agent collaborative learning arithmetic. Role-based colony communication and cooperative rules are also provided,which enrich theories and mothods of MAS greatly.The proposition of task-distribution arithmetic among group,provides a more effective method to task-distribution.
