Designand Research Of Network Teaching Platform Based On J2EE

With the rapid development of computer and network, it came into being that all kinds of applications based on the computer network. Computer networks teaching is an important web application. Comprehensive application of computer network technology and multimedia network teaching of modern technology make traditional teaching functions being an extension in time and space, and it is an important aspect of service of sharing the information resources in Internet. Colleges and universities have built a network of teaching that has a unique advantage of information technology. The most colleges and universities is planning to develop teaching applications system based on campus Network, Because they have been building a good foundation for the campus network hardware, and the leadership attaches great importance to construction and use of teaching and learning environment. Therefore, the development and application of network teaching platform is important. This article is made in this context. Research and development of network teaching platform will be conducive to the professional courses in the teaching of the smooth network development and management to raise the level of teaching, as well as colleges'information to meet the long-term needs of development.This article designed a teaching platform which meet the needs of network teaching for most colleges and universities, based on the common network teaching platform and the analysis of the investigation, and the reference of domestic and foreign similar product development and research achievements. The system basically realize management module, educational administration, teacher module, student module and so on. At the same time, the system makes use of network teaching class in outstanding teacher and the functional carrying out campus network multi-media teaching conveniently, gives consideration to convenience teacher and student that the student learns and autonomously exchanging interactive need. The system has the chat room, the plentiful visitor and having asked questions. For the teaching-learning evaluation process is particularly useful for network test systems, test paper this algorithm in the implementation technology and focus on the study.Paper focuses on J2EE technology and the MVC pattern, the current design of the more popular way Struts+Spring+Hibernate framework, open source tools such as learning and research. Final integrated use of these technologies and tools for design of a network teaching platform instance. Application of improved genetic algorithm for generating test paper quality, has been achieved, but the convergence rate has not improved on paper, required further study.
