CAFEKS (Computer-Assisted Free Exploration of Knowledge Structures), we have thus far developed, can be considered a kind of general purpose hypermedia system with its retrieval and guidance capability greatly enhanced by means of knowledge / problem description and inference based thereupon. In the course of the cognitive study of concepts, knowledge units and problems as knowledge-base elements, it has been revealed that, in order for the student to acquire principled use of domain kowledge, it is crucial to provide him/her with application instances in sensory-motor stimulative presentation with which he/she can interact to select options or modify / manipulate situations and make him/her explain the commons and differences. In addition any knowledge could not be fully represented without being embedded in a description of the world in which it plays its role. Thus in CAFEKS- knowledge is communicated to the student relative to some context defining media presentation and there are … More accepted his/her interventions as well.Word algebra problems, electrical circuit theory, electro-magnetics, programming in Prolog, UNIX command were chosen as sample domains. On the one hand systems of primitives have been developed as components of the knowledge descriptions in Prolog for these domains. On the other hand we prepared abstract component objects of media metaphor presentations utilizing X-window tools. And we have devised an interface utility enabling the programmer to write methods in the knowledge /problem objects for constructing media metaphor presentations of the knowledge / problem in combination of the media metaphor component objects. On this scheme the student is able to describe his/her problems, making the system to simulate the situations under his/her settings and the system can accept his/her interventions. Exploiting the knowledge-driven simulation. capabilities, the system can monitor the explanations made by the students by measns of knowledge exploration. Less

CAFEKS（Computer-Assisted Free Exploration of Knowledge Structures）是一种通用的超媒体系统，通过对知识/问题的描述和推理，大大提高了系统的检索和引导能力。在对概念、知识单元和问题作为知识基础元素的认知研究过程中，研究表明，为了使学生掌握领域知识的原则性运用，关键是为他/她提供感觉-运动刺激呈现的应用实例，使他/她能够与之互动以选择选项或修改/操纵情境，并使他/她解释共同点和差异。此外，任何知识如果不嵌入对它所扮演的世界的描述中，就不可能得到充分的体现。因此，在CAFEKS中，知识是相对于一些定义媒体呈现的上下文传达给学生的，并且存在 ...更多信息 词汇代数问题、电路理论、电磁学、Prolog程序设计、UNIX命令被选为样本领域。一方面，系统的原语已开发为组件的知识描述在Prolog为这些领域。另一方面，我们利用X-window工具准备了媒体隐喻呈现的抽象组件对象。我们已经设计了一个接口实用程序，使程序员编写的知识/问题对象的方法，用于构建媒体隐喻的知识/问题的媒体隐喻组件对象的组合表示。在这个方案中，学生能够描述他/她的问题，使系统模拟他/她设置下的情况，系统可以接受他/她的干预。开发知识驱动的仿真。能力，该系统可以监控学生的解释，通过知识探索的措施。少
