J2ee-based Network Teaching System Research And Design,

With the continuous development of computer and network, the information of the society is evoluting and the information technology is penetrating every domain. The development of network teaching just is a good example of it. Comparing with assistant teaching which used computer autonomously at one time, network teaching makes use of computer to browse computer information resource all around the world. Viaing network, it can accelerate more comprehensive communication between teachers and students, manoeuvre the initiative of students adequately, put diathesis education in good force. So it fits for the requirement of education situation at the new time. It's necessary to establish the network teaching platform. Universities in China started the network education under this situation to meet the need of development of the society.This research aims to bring up the work of developing network teaching system.Network teaching system is an auxiliary teaching and learning IT environment over the campus network . In the environment , teachers can prepare for lessons ,make courseware , teach lessons and correct students'exercises , students can play courseware , learn by themselves , take their examination online , teachers communicate with students and attend question-answer , and so on .In this paper, we introduce the network teaching system based on J2EE architecture, which is developed for the problems existed in the traditional teaching of Guangxi University for Nationalities, combining the prevalent modes of network teaching and up to date academic achievements both home and abroad and using the more sophisticated network techniques at present.The demands and analysis,design of the network teaching system will be discussed particularly from the points of the system design aim,user characteristics,running environment.The J2EE technique and MVC mode will be quoted to design the scheme of the network teaching system based on the N-tier B/S structure .And a new scheme of the network teaching system can be bring up in the end.
