Design And Implement Of The Web-based Cooperative Learning System

Design and implement of the web-based cooperative learning system (WBCL) were mainly studied in this thesis. The scope of this study included collaborative learning, CSCL (Computer Supported Cooperative Learning) and KBC (Knowledge Building Community). Some research methods, e.g., literature review, antitheses, demonstration and virtual observation were utilized into this study.First of all, the research status and development trend of the current collaborative learning research in our and other countries were reviewed. Then the basic study objects, emphases, targets and methods utilized in this thesis were introduced.The theories of collaborative learning, CSCL and KBC were analyzed and summarized by literature review and content analysis in this field. After the detailed discussions of the theory of the collaborative learning, the relation of WBCL and KBC were analyzed. Through the comparisons, this paper showed that the web-based collaborative learning is more appropriate for the Community's Knowledge Building, and proposed the principles and approaches of the teaching design based on WBCL system.This paper also discussed the concrete design of WBCL system, mainly including the design principles, various function blocks and the flow of usage, etc., especially the design of graphic interaction. The design principles of WBCL system were mainly embodied as constructive uses of authoritative sources, rise above and knowledge sharing. The design of the function blocks of this system covers the resource, ideas, grouping, collaboration, products and evaluation etc.Now, we have finished the basic functions of the WBCL system. This system was applied to the actual courses: the courses of the Webschool Tsinghua Univ. and the "The multimedia design and implement" course. From the investigation of the courses, the system took the practical effects.The future work of the present study mainly include the improvement of system design, the fulfillment of the system development, the popularization and evaluation of the system, and also the further optimization of the system according the evaluation results.The present study is the sub-project of the online-learning management system, the National 10th Five-Year Sci&Tech Project.
