Middleware-based Interactive Network Teaching Environment Research

With the development and popularity of network technology, especially the Internet Technology, the network teaching has been the main manner and the tendency. Long-distance teaching is the result of the application of the computer and network communication technology to the whole to the teaching area. This new mode of teaching is realized fully by network, and impacts on the whole education structure. That is the tendency of the future teaching development. Network teaching system is constructed for the purpose of this kind if teaching mode and for the development of teaching need.The paper careful analyzes domestic and international network teaching of the actual situation, the mode of teaching modern network, characteristics, and problems. Based on the above understanding, the paper research the WEB system of multi-tier architecture and middleware technology representing the construction course of the network teaching system based on middleware technology and the composite structure of the B/S and C/S, on the base of the analysis of the requirement to the network teaching system construction. The network teaching system in the J2EE platform development uses Struts framework combining Web application, based on a distributed software design pattern-MVC. By using of Struts, the structure of developing work became hierarchal.Network teaching system functions, including teachers prepare lessons, courseware, teaching, students self-learning, online examinations, teachers and students exchanges, FAQs and other teaching. To online exam as an example, the paper detailed descript the entire module of the development process, including the logical structure of the design, arrangement of system, web presentation layer that the design and implementation, business logical design and implementation, and discussed the development of key technologies in the process.
