一个通用多功能CAI系统的设计与实现

The Design and Realization of A Universal and Multifunctional CAI System

本文首次提出了一种通用多功能CAI系统的设计方法。系统对教学内容库进行操作,只要切换教学内容库便可进行另一相应课程的计算机辅助教学,这就是通用性。系统由教学模块、质疑模块、命题模块以及维护与扩建模块组成,从而体现了多功能性。由于我们对库结构进行了合理的考虑和严格的描述,这使得在人机会话的过程中,系统对用户的合理要求有较快的响应速度。

In this paper,a method of designing and realizing a universal and multifunctional CAI system is presented for the first time.The system works with a data base for contents of courses.Replacing the data base with the system fixed,we obtain another CAI system.It is what universality means.Since the system eonsists of modules for teaching,Calling in questions and setting questions, we say it is a multifunctional system. Since a reasonable consideration and a rigorous description to structures of the data base has been made,the system has a qnick response to the reasonable demand made by users.
