CAI的动态全局规划

Dynamic Overall Planing in CAI Systems

在 CAI的研究和开发过程中 ,如何把领域知识、学生模型、与具体领域有关的教学知识 ,以及与具体领域无关的教学原理和方法有机地结合起来 ,对领域知识进行动态全局规划的核心问题一般都被回避 .文中将领域知识看作概念以及概念之间的关系 ,把 4个方面的知识有机结合起来 ,找到了对领域知识动态全局规划的内在规律 .同时 ,可以用优美简洁的建基于集合论之上的数学模型表示 .

During research and development of computer assisted instruction (CAI), the predecessors had evaded the kernel of CAI, namely, how to combine domain knowledge, student model, tutoring knowledge related to specific domain, and tutoring principle and method unrelated to specific domain as four aspects into an organic whole, so as to play domain knowledge in dynamic and overall view. The authors have solved this problem if domain knowledge can be looked upon as concepts and relation between concepts. Thus the four aspects of knowlege can be combined into an organic whole; the inherent law governing planning domain knowledge in dynamic and overall view has been found; and the law can be expressed by a fine and pithy mathematical model based on set theory.
