Research On Web 2.0-based CSCW Network Teaching Platform

With the modern society developing swiftly and science technology changing quickly, life-time study has become the common requirement and trend of the international education and development and network teaching platform(NTP) is the perfect one for shouldering and executing the life-time study. The changing process from the initial C/S NTP to the posterior B/S one, reflects the renovation and self-mediation for the pedagogy brought by the technology. Therefore a brand-new NTP, a CSCW NTP based on WEB2.0, which applies to the teaching model of students being centered and teachers dominant and uses flexibly varied studying theories, such as constructivism, reflective, new behaviorism and so on, to get twice the effect with half the effort in the teaching, has come to birth.This thesis is focused on analyzing the basic components in the CSCW and WEB2.0 and improving them. In the thesis, we firstly analyze the functions of the WhiteBoard component in the CSCWS as well as the video meeting system. In the teaching activity, there are two roles of teachers and students with different access rights so we adopt the concurrent controlling strategy based on creators and roles in the Whiteboard, and adopt the multi-president and roll-polling concurrent controlling strategy in the video meeting. To keep the important information available in the teaching and communicating between teachers and students, we append the content-saving function in the Whiteboard and network meeting; on analyzing the Wiki and Blog components'function in WEB2.0, out of the only partial visibility and editing needs of articles to be published in the teaching, we add the access-right-dispatching function and visible property-setting items for Wiki and Blog; on integrating the functions of improved components, we create the Wiki-Whiteboard suitable for the teaching and combine the Blog with Wiki-Whiteboard conveniently in the Blog on the basis of the variance of access rights endowed by subject-creator.Eventually we particularly introduce its designing principles and implementations of the and WEB2.0-based CSCW NTP, and provide the specified application and deployment of this NTP.
