In the experiments in information system analysis and design, we use Microsoft Visio 2003 as a main tool to do analysis and design, and students are guided through their experiments by electronic classroom software.

By means of using virtual electronic classroom software,it promotes the students\' manipulating skill though the integration of introduction and training,and changes the way of teaching.

E-classroom Multi-media Network Terminal Controller;

Multi-cooperation Just-In-Time Information Retrieval and Application in E-classroom;

In answering to this, the article puts forward a solution with multimedia, group activity, network and computer classrooms int.

Combined with network E-teaching-room software and protecting card software, the teaching system can afford multimedia teaching and be visited based on B/S, It improves the activity of class, resolves the problem in practice teaching, and the system costs not very much, easy to expand and migrate.

And according to the commonly realizing way of multi-media electronic class, this paper proposes a solution which combines soft and hardware technology, and realizes a efficient and effective multi-media teaching system under conditio.
