The Design And Realization Of Online Learning Communities Based-on Ajax Technology

Along with the development of information technology, people tried to establish a variety of online learning platform for learners to provide rich learning resources, and at the same time through network learning platform, learning broke the limitations of space and time. The learning environment of network platform is not enough to support learning communities, making learners produce network study fatigue and loneliness ,and network study has no organization, no guidance, it is hard to form a online learning community. If the learn at network learning platform can be like real classroom's learning, teachers guide students, students study together and help each other ,it will be helpful for improving the effect of online learning, which leads us to secure the research of online learning community .Building online learning communities need good network environment, such as conducive interactive, easy to operate, reducing waiting time etc .Ajax can provide technical support to realize these effects, Ajax through a variety of old technology portfolio, realize new ideas. With Ajax as the core technology, this paper research and design how to build the online learning communities.This paper describes the learning community and the community learning environment on network platform, deeply research how is the "learning "and"community " to combine, as well as the theoretical basis of learning community and the online learning community .These theories provide support for designing online learning community platform. Meanwhile this paper research the combination of design-base learning and learning community, to propose taking design-base learning organization method conducive to facilitate the online learning community on network platform. In the above theory research foundation, with the related theory of learning community as the guide, this paper takes on demand analysis and designing for the learning community support platform. In the design of the platform, Ajax technology provided support to promote the online learning community, then built a development environment of network platform, and achieved some of the module development.
