Researd And Application Of Collaborative Virtual Learning Environment

Today we live in information society, and in the rapid development of computer and network technology today, education has gradually turned to information technology. Education information is the use of information technology for educational reform and thus promote the process of modernization of education, it not only creates information-rich learning environment for educators, especially students offer great scope for development, Virtual Learning Environment Network Teaching Support also came into being at this time.The rapid development of information technology today, the traditional way of teaching the teachers have been unable to meet student demand for quick information in a timely manner, and teachers, many individuals can not provide a lot of learning information. In addition to traditional teaching to teachers, lesson, student lectures supplemented by way of active learning can not play the enthusiasm of the students. Based on the traditional teaching of these issues, this thesis, a student-based online virtual learning system. Through research, found that learning through this learning system, made more obvious learning effect. Compared with the traditional teaching, People in the learning system in the knowledge gained to their study, work and life more meaningful. Traditional teaching by the time and space constraints, and the system is broken time and space constraints, so the system reflected in the other focus is the interactive learning process, that is man-machine-human interaction between the 22, especially the people-interaction between people. As long as the same time into the learning system, teachers and students, the life and life can be in real time between the online exchange study.Through this paper an overview of the virtual learning system, the analysis of the virtual learning model, on the education system has advantages and disadvantages of network analysis, then presents the original model of the learning system functional requirements. This paper analyzed according to functional requirements, listed the detailed design requirements, the use of advanced three-tier network architecture, that is, the browser/WEB server/database system with three-tier structure. In the overall analysis system based on the structure and function, proposed using ASP.NET (C#) programming, ADO.NET database access technology, Ajax prototype learning systems framework for technology development programs, and to design and implement a Collaborative Virtual Learning System papers from the system's structure, function, use of key technologies and its implementation were introduced.This thesis implements a number of network environment learning process, individual learning, group discussion learning, teacher-student exchange learning. Using ASP.NET (C#) technology to achieve a system of network design, using SQL Sever 2000 designed a learning system user information and resource database, and use ADO.NET technology to access on the database. Also through the back-end database, realized different users different permissions set up and manage to ensure the system operation quality and use efficiency. Finally, local area network system to simulate the operation and use of this test, the experiment proved that the realization of the system is feasible, with a wide range of practical value.
