Because the teaching system based on Web has kinds of advantages, teaching system based on Web will develop strong and continuously in the near future. The intelligentization will be as the development of The Computer-Assisted Instruction (CAI) of 21 century , at the same time the CAI will combine with the Internet and multimedia technology etc.So that it can assist teaching system and education career.This paper discussed the design and realization of network teaching system, test on-line system, network answer system, network leave word system , E-Mail, video teaching system, management center system. For improving its efficiency and its actual application, the teaching system used Visual C#.NET, Sq1 Server 2000 and VRML etc. This thesis resolved a few problems at the same time:1. Realization of dynamic network exam database and the realization of answer in DWF;2. Design and realization of the network answer system and its aptitude control problems;3. Resolved E-Mail's sending problem4. Share of famous colledge graphics media informations and movies;5. Execute a great deal of cartoon model for understand teaching content.
