Xml-based Real-time Collaboration, Research And Design Of The Learning Environment

Based on the research into the application of a mass of collaborative learning environments, the researchers have perceived that the environments do not completely fulfill the expectations on supporting interactive group learning. This is due to the fact that the asynchronous forms of interacting do not satisfy the students with social affective requirements and group attachment. Accordingly, the better forms of real time interaction in collaborative learning environment are in demand.There are two alternative solutions. The first one is to provide various real time collaborative tools in the learning environment to meet different needs based upon the specific collaborative strategies. The second one is to establish a standard and incorporate all the implementations and developments into the constituted frame. The latter one is the ultimate solution which can offer the shared resource and shared services.This paper discusses the current collaborative learning systems and gives the investigation into their application. According to the feedback from the teachers and the students the paper suggests the limitation of the current systems, such as social interactive deficiency, share deficiency and the absence of standard.The paper describes the theories of constructivism, activity and peer relationship and indicates their meaning for the design of the real time collaborative learning environment. The paper constitutes the core protocols supporting the implementation of the real time collaborative learning environment based on the XML, incorporating the protocols of XMPP and JEP, and presents the model based upon the protocols. This paper discusses the core protocols of the real time collaborative learning environment based on the XML presently. The latter research have been going on in the open source project InstantCo(http://sourceforge.net/projects/instantco/) consisted of the further specific, the implementation of the protocols and the developments.
