Design And Implementation Of The Campus Network Teaching Applications

With the application of computer network technology, popularization of the Internet and development of 3G network technology, network-aided instruction (NAI) is achieving unprecedented and powerful technical support and method and becoming increasingly popular and more widely applied. Network-based NAI system has already developed into the stage of immediacy from the stage of digitization, intelligentialization and individuation. New communications'technology is not only serving for delivering up-to-date information and knowledge but also providing more ways for teacher-student interaction. NAI system provides an instruction environment for teachers and students in and out of class since it is suitable for school intranet and internet without the limitation of space and time.The system discussed in this thesis is an applied system for NAI and instructional management, which is based on the technology of .NET, adopts new object-oriented language C#, combines with the technology of ASP.NET, ADO.NET and Web services.First of all, the thesis introduces the background information of system development, the current situation and development trend of NAI system and .NET framework. Some key technologies including ADO.NET, ASP.NET, XML, C#, 3G are emphasized in the introduction of the system development process. After the development mode, platform and languages are analyzed and compared, it is determined to use B/S model, .NET platform, C# language to develop the system. Secondly, it introduces the system's requirement analysis, general framework design, two functional module of mobile phone classroom and information announcement, design of database and form and its main functions. Finally, it introduces the realization of the system and outlook for future research.
