摘　　要：首先分析了计算机辅助教学(CAI)这门课程在教学过程中存在的问题。遵照"高内聚,松耦合"的软件设计原则,构建了一个基于.NET的CAI教学服务平台实现模型。然后对平台的功能模块进行了设计。最后,叙述了平台开发过程中的一些关键技术,并着重阐述了利用工厂模式(Factory method)实现数据访问层通用接口的过程。目前,该平台已得到很好的应用,师生反馈意见良好,CAI也被评为校级精品课程。The problems in the teaching process of ＂Computer Aided Instruction （CAI）＂ course are analyzed firstly. According to the software design principle of ＂high cohesion, loosely coupled＂, a CAI teaching services platform implementation model based on .net is constructed and then the function modules in the platform are designed. Finally, some key technologies in the development process of the platform are described and the implementation process of data access layer universal interface by use of factory method is elaborated. Now having been running fluently, the platform gets good feedback from teachers and students and CAI is also evaluated as school-grade excellent course.
