The Design And Realization Of Distance Education System Based On The IP Network

The modern distance education is a wonderful combination of traditional education and modern communication technology. And the distance education based on the IP network is the main realization mode and the major evolution direction of the modern distance education. Now, with the improvement of the people's living quality and the requirement of the lifetime education, people give higher requirement to education on space, time and the mode of obtaining knowledge, which will certainly promote the further development of the distance education.In this dissertation, we have proposed and realized an education resolution based on the B/S structure, which has combined the hardware, software, media resource and management of teaching. We have deeply investigated the realizing mode and the technology, and analyzed the advantage and the disadvantage of the current existing reeducation system in the first portion of this dissertation. Then, according to the three layers network structure of the interactive system based on browser/server, the technological route is confirmed. The technology of Stream media and ASP, which is used on the server side, is the basic design technology of the item. The method of modularization is used in the paper. In terms of the distinction of all the modularization, the platform is divided into two parts: trunk system and sustaining system. While designing the trunk system of the platform, we have realized 5 main educational functions: network classroom, living broadcast classroom, courseware on demand, intellectualized exam and score management. A real-time and interactive teaching mode based on the combination of text intercommunion and living broadcast has been proposed. Some auxiliary functions of the distance education, such as online homework, BBS system, resources download and so on, are realized. A new homework mode, through which teachers can assign and read over homework and students can do them online, is put forward. The dissertation also has realized the development of the basic function of mobile learning based on SMS, with the information issue, information inquiry and mobile dictionary as the main content. A new application of SMS based on the transmit mode from terminal to terminal is put forward and completed.In the end, the paper sums up the main research work and development tasks that I have achieved during the researching time, and puts forward the following work of the item.
