The Research To Construcion Of Virtual Learning Conmumity Based On Concept Of Eco-Learning

With the rapid development of network technology, especially Web2.0 technology becoming more mature, as well as the lifelong learning and humanism widespread, striking deep roots in the hearts of people, E-learning which is one of the important methods of study has experienced dramatic changes. Virtual Learning Community as important platforms for network learning has been paid more and more attention. It provide an open learning environment for learners, then each learner can take part in therefore individual can gain learning ability as well as share the collective wisdom. But presently, the separation of teacher-student teaching activities and the rigidity of virtual learning community structure which bring the imbalance in the virtual learning environment, Resulting'in imbalance in Network Ecosystem and seriously affecting the function of the virtual learning community.This article analyses Virtual Learning Community from the perspective of ecology, it thinks that virtual learning community is E-learning ecosystem consisting of the learning subject and the virtual learning environment. It builds a syntactic model of Virtual Learning Community grounded on Eco-Learning Concept, on the basis of Virtual Learning Community characteristics and main functional modules analysis, combined with the integration between modern learning theory and Eco-Learning Concept. It also analyses the ecological properties of the structure, so are the main factors and environmental factors of the structure. It provides a new way to promote the building of the Virtual Learning Community, aiming at eco-sound development of Virtual Learning Community to, while joining the ecosystem concept and dynamic equilibrium concept into the construction of a virtual learning community.What's more, according to the requirements for ecological study concept, it develops ecological Virtual Learning Community upon the systematic, open, interactive, diversity and liquidity and so on with the help of open-source learning management system. After a tryout of the Ecological Virtual Learning Community, it elicits the process of forming an ecological virtual learning community and predicts the development tendency of the Ecological Virtual Learning Community through the analysis of social relations in virtual ecological learning activities by social network analysis tool Pajek.This paper provides us a new idea, because it studies the virtual learning community from an ecological perspective, be beneficial to its own development as well as the development of individual learners in the virtual learning community, but the ecological imbalance of Virtual Learning Community is the follow-up subject.
