摘要
文中参照认知信息处理模型提出建立以超文本结构为基础的ICAI系统的方法.为了增强控制的灵活性,系统建立了教学知识的分层模型(实体级、概念级和单元级)及其在概念级上的三种链接(控制链、浏览链和固定链).同时定义期望值以表示教学知识的重要程度,使得系统能够自动地确定学习的重点,从而对教学参数进行调整.
Here discussed is a method of constructing a hypertext based ICAI system according to the cognitive processing model. In order to be organized more flexibly, the learning material is divided into three levels (entity level, concept level, and unit level) and there are three links at the concept level (control links, browse links, and fixed links). Moreover, expected value is defined to represent the important degree of the learning material, and then the system can automatically determine the learning emphasis and adjust its pedagogical parameters to satisfy different students.
