Network Aided Teaching System Based On.NET Design

Along with the development of computer technology, network teaching hasbecome a modern educational trend. The network teaching system was based onnetwork, and it can provide more people with more education opportunities.So thatnetwork teaching has become an important development direction of modern education.Based on the analysis of the existing various kinds of network teaching system,this article demonstrates the development of small and medium-sized network aidedteaching system which was based on the net technology and with independentintellectual property rights and specific teaching needs, and we will design andimplement a network aided teaching system. After analysising the teaching process, wewill get the system data dictionary, through the further analysis,we will design thesystem function structure. and according to the system design, security design,environment configuration, and we can get a specific design and implementation to theassistant teaching system.We choose the SQL Server2000as background database, Microsoft Visual Studio2005and the C#language as the development tool,and the network aided teaching wasunder the ASP.NET working structure, and realization three identity(teacher, student,the administrator) user login function.The teacher subsystem can accomplish uploadingand editing of courseware and tutorials database.The students subsystem can view classand tutorial information in the foreground, downloading tutorials, video.The studentscan ask questions, and teachers can answer questions,the students can have self testingand other predetermined function;the background administrator subsystem have systemmanagement and maintenance functions.This system realized online teaching function,after testing and commissioning,it achieved the design goal and requirements.Comparing with other similar existing systems, this system has many features:first, the system can provide three kinds of user’s authority through userauthentication, greatly improves the safety of the system and the convenience ofmanagement; secondly, its personalized interface design makes its usage simple andeasily. Third, the teaching system designed by different characteristics of specific course, can meet the needs of specific course.fourth, the system has independentintellectual property rights, so that it can conveniently upgrade and extent its functionand can effectively control the cost of the system, so that it has good flexibility andapplication value.
