Design And Practice Of Learning Activity Supporting Collaborative Knowledge Building In Wiki Environment

With the rapid development of network technology, based network environment carrying out learning activities are increasingly becoming a hot and trend. Data indicate that the current network-based environment carrying out learning activities still have a large number of issues that must be resolved, such as learning resources can not be dynamic update and expansion and the depth of knowledge construction can not be achieved, in particular, how to conduct teaching design for web-based learning activities. Wiki is one of the application softwares in Web2.0, which can provide the resources sharing platform and consultation room for Wiki community. Collaborative knowledge building is a progress, community, through consultations and argument, build a dynamic public knowledge base. It is worthy of study and discussion how to put Wiki community, collaboration knowledge building and learning activities together designing learning activities supporting collaborative knowledge building.Based activity theory, social constructivism theory, situational learning theory and distributed cognition theory, from the perspective of instructional design, this study aims to design learning activities supporting collaborative knowledge construction in Wiki environment, and make research to modify, improve and test the scientific, operability and effectiveness of design.This paper is divided into six parts, namely, introduction, theoretical overview, instructional design, experimental research, results analysis and summary. Introduction analyze the status quo at home and abroad as well as problems through the content analysis method and study of literature. Theoretical overview, first define the three concepts, and then based on the four kinds of theories, analyze the six elements and element relationships supporting collaborative knowledge construction of the learning activities in Wiki environment. Instructional design is the instructional design of learning activities and process. Experimental research is through three action research, modify and improve the instructional design program and verify the application effectiveness of design. Summary is a summary of research findings and follow-up research directions.Research results, this paper firstly demonstrated feasibility of design program of supporting collaborative knowledge building of the learning activities in Wiki environment. Secondly, this paper put forward five modules supporting collaborative knowledge building of the learning activities in Wiki environment. Then the paper elaborate three aspects supporting collaborative knowledge construction of the learning activities in Wiki environment. Lastly, by experimental research, the conclusion is that the design of the learning activities based Wiki environment is conducive to the students which can support collaborative knowledge construction.
