| 摘 要： | 决策支持子系统是基于网络的适应性教学系统NBATS(NetworkBasedAdaptiveTuroringSystem)研究的重点和难点,其主要功能是为教师依据学习者个性特征制定教学策略提供技术支持。为解决NBATS系统决策效率问题,论文提出了采用开放式决策支持子系统的设计方案,并使用模糊聚类算法对学习者进行分类,针对不同分类的特征施以不同教学策略,从而使NBATS的决策支持子系统能够适应不同学科、不同学习对象和不同教师的决策需求,并提高了决策效率。

| Abstract: | Decision support system is one of the key sub-systems and tough issues in NBATS(Network Based Adaptive Tutoring System)area,and most of its functions are prividing technical support for teachers to make instruction strategies based on learner's characteristics.In this paper,a design method is presented for open decision support systems ,where learners are classified by fuzzy clustering algorithm in order to adjust instruction strategies by the characteristics of each learner group.Therefore,the decision support system of NBATS can be adaptive to the demand of various kinds of teachers,subjects and learned-objects,while the decision efficiency of NBATS is improved. |
