The Research And Realization Of Network Collaborative Learning System From Perspective Of Km And Multi-Agent

Because network is getting involved deeply in education, Chinese education is taking on an entirely new look. Specially, open,multi-media,virtual and rich-resource of network is regarded as best carrier of collaborative learning.Through rational analyzation and deep probe to current stituation of Network-based Education, I find out bottleneck problems during development of Network-based Education,raise a resolution that base on theory of PBL and theory of CSCL,integrate Multi-Agent technology and Visc technology, design and realize a Network Collaborative Learning System based on C/S architecture, complete main idea of KM-transformation and origination of knowledge.During the process of designing and realizing Network Collaborative Learning System, the research work of the following several respects has been done in this paper: ①Choose a similar three layer of C/S system architecture,that is to say, collaborative learning users layer, Multi-Agent application layer and data service layer, take integration of Multi-Agent technology and mature technology of C/S system architecture into full consideration.②Employ some surveying table for getting data about feature information of learner,and quantify them,help teacher to group more effectively. ③Construct architecture model of NBCL and process model of NBCL, introduce separately the their detail, direct the design work of system. ④Use rapid prototyping method of software project, take Java as programing language,implement development of each system layer. ⑤Concept mapping tool make knowledge transformation and origination easily.Network Collaborative Learning System base on modeling learner information, it see PBL as starting point of learning activity, collaborative learning launch in collaborate group. It will stop while end of problem solving, and its aim is improving learner ability of problem solving and originating knowledge. All work that I do is a exploration for solving education facing problem now.In sum, this paper is only farther trail of theory and implement on Network-based Education, what its effect need the test of teaching. Improving sintelligence and interaction of Network-based Education , humanizing it, teaching students in accordance of their aptitude still have a long way to walk.
