Research And Realization Of A General Multimedia CAI System

With the popularization of computer and the development of multimedia technology, the multimedia courseware need to be high quality and more quantity, developing courseware with platform system turns into an important method and trend. It can improve the efficiency, reduce the cost, shorten the period of the development, and also it has great significance to the development of CAI technology. But present courseware developing platforms often need high level computer technology, so it limits the courseware in the balanced development of technical content and education idea.This system is developed basing on the summary of other CAI softwares and is applied in the University. A teacher does not need to grasp any homepage designing tool or network programming principle with the help of this platform, thereby the technical threshold of courseware developing is reduced and the anticipated goal is achieved.The CAI system is divided into four modules. They are edit module, teaching module, injure module and interactive function module. The four modules are independent each other and meanwhile constitute a unified system.In the system. The Courseware has the characteristics of integration, interaction, scalability and generality. The system has the stronger editing ability of word and graphic; supports rich media play modes, realizes smoothly interactive. Users can edit the word, graphic, picture, voice, animation and movie togather. And also can edit formula.The system realizes the mixed arrange of word and picture and text-to-speech. Even not at local the interactive function part can make teachers development courseware logon to the server. If you remote login, you can make and modify courseware. The modifed contents will be saved to the database and embodied to students' terminal.This system which can fit many subjects' teaching software and making, creating, managing and using items bank brings forth new ideas. Though the system editor, it can realize modification and perfection with time and environment changed. On the other hand, it combines MSTTS and database technology to simulate real teaching scene. At last it can realize following spoken ability. Meanwhile, it makes a multimedia editor platform which can implant image in the text and store information in the database, it can use stream technology to read these data. So this system can occupy small disk space.
