ABSTRACT

With the use of computer network technology, database technology and the virtual instrument technology to experimental teaching system, remote control, remote access, long-range use of the virtual devices become true. The online teaching, network management of the experimental system are achieved by the use of dynamic server page (Active Server Pages, ASP) technology, enabling the users to receive online teaching, to make experiment appointment, to make network discussion ,to submit experiment report at any place through the Internet. The system is fully functional, easy to operate, can train the students with practical ability and the spirit of innovation, and is conducive to raise the teaching of experiment and the level of management.
This paper mainly introduces the concept, features and functions of the virtual laboratory. It also analyses the key technology required for virtual laboratory, and it makes the introduction of the hardware and the software of the laboratory. Taking the experimental teaching of mechanical basis as an example, this paper studies the building programmes and the implementation methods of the online virtual laboratory. In addition, computer technology, network technology, dynamic web page technology are used in the example to achieve network teaching and teaching management.


Key words: virtual laboratories, teaching networks, remote virtual experiment
