The Research On Social Interaction And Promoting Strategies In CSCL Environment

With the deepening application of computer internet technology in education, people have changed their research vision from individualized instruction supported by computer(human-computer interaction) to human-human interaction supported by computer and internet. In this trend,the Computer Supported Collaborative Learning(CSCL) supported by computer has become a new promising research area in educational technology in recent years, which emphasizes on using the cooperative effects of computer which is good at processing and disseminating information, and the interpersonal interaction to optimize the learning performance. However, the existing researches show that it cannot ensure effective collaborative learning if learners are simply put in a communication environment of common task. Because in specific application, the learners can’t participate in the collaborative interaction actively, and the CSCL platform or tools don’t concern and guide the learners to take part in the whole process, expect the function the simple communication. These are caused by the lack of depth research in coordination and interaction mechanisms.To solve above problems, the constituent elements, classes,processes and so on are elaborated in details firstly. Secondly, the methods framework of promoting social interaction is raised, which includes tactics and tools two parts. The team organization and management strategy, learning monitoring strategy, evaluation and incentive strategy, and maintaining social space strategy are introduced in the first part, and group awareness tools(GATs), scripts, socially shared metacognition tools, feedback and reflection tools are introduced in the tools part, which not only support the whole processes of social interaction, but also focus on the promotion strategies which have introduced. This research has strong theoretical significance and practical value, which offsets the insufficiencies of promoting strategy and tools in CSCL.
