具有适应能力的Web课件设计与关键技术

传统的基于网络的CAI系统由于缺乏推理机制和学生模型的支持,不能根据学生的知识水平、认知特点和理解能力提供适合该生的学习材料并作出有针对性的指导.介绍了一种基于Web的具有适应能力的课件模型,它综合利用人工智能技术、多媒体技术、数据库技术和网络技术所设计的课件,能让学生根据各自的学习情况动态组织教学内容,为学生提供个性化的服务.讨论了实现过程中的关键技术.

Design of Web courseware with adaptive ability and its key techniques

The conventional computer aided instruction (CAI) system based on network is lack of the support of reasoning mechanism and student models, so it can not provide the special learning data and guidance for each student according to his know-how, cognition characteristic and comprehension. A courseware model based on Web is presented in this paper, which comprehensively makes use of artificial intelligence, multimedia, database and network techniques. The courseware designed by using the model can provide dynamic instructional contents, and it provides individual service for each student according to his special learning situation. Three key techniques in the implementation of the courseware model are discussed in detail.
