Based Web Colleges And Universities Open Experimental Teaching System Design,

With the application and rapid development of Internet technology, network affects all aspects of people's lives. There is no exception in university. Network technology has been spread and popularized in the teaching and management of universities. We can make the best of the favorable conditions and resources, and integrate database system, ASP.NET technology, network communications, multimedia technology and other relevant information processing technology to construct a Web-based open experimental teaching system unlike a traditional experimental teaching structure.Recently, many university laboratories have developed some experimental teaching platform, but almost are all independent systems. In fact, these teaching platforms are all multimedia teaching aids only. They can not unify to be a teaching environment integrated colligation and openness of experimental teaching management. Many colleges and universities have already realized the importance of the web-based experimental education system and made some research.Web-based open experimental teaching system plays an important role on reasonable distribution of experimental resources, guarantee an open laboratory and other aspects of operation. Meanwhile, this system extends the space and time of the traditional laboratory, provides a new experimental and communicating platform for teachers, students and administrators. On one hand, teachers can know the students more and easy to organize the experimental teaching; On the other hand, students can get help from experimental teaching system anywhere and anytime. This will accelerate the build of university laboratory information network and improve the teaching and experimental skill.Open laboratory system is a virtual computer network experimental platform for the Web, mainly implement computer network experiment teaching. This paper discussed the development of ASP.Net based framework and relevant technical of Web applications. And then, introduced ASP.Net based framework of open laboratory system. To focus on system efficiency, reliability, scalability, reusability, easy of use and other aspects of the request, we expounded the main idea and design of a new generation of open laboratory system, introduced the open laboratory system data structures, database structures and the corresponding algorithm, and implemented the specific requirements of the system performances and operational functions.The system designed from Microsoft three-layer Web architecture of ASP.NET framework. It solved the problems of two-layer structure and implemented integrated network of virtual laboratory system which is efficient, flexible and easy to maintain. System architecture mainly consists of four parts—resources, students, teachers and teaching management. It's helpful to enhancing the operating ability and developing the creativity of students.
