ITS的设计与实现

The Design and Implementation of ITS Model

从认知科学、教育心理学、人工智能和计算机辅助教育等方面着手,设计并实现了一个双主型的智能教学系统(ITS,IntelligenceTeachingSystem).在设计部分,给出了ITS的结构和领域知识的知识表示,提出了基于加权产生式规则的教学策略推理机;依据认知学习理论,设计了一个采用逐步逼近法的有学习历史继承的认知学生模型和学习过程自动导航的教学模型.在实现部分,研究了推理机的实现,并尝试给出一个智能教学系统模型的初步实现.

A dual-initiative intelligent teaching system is designed and implemented which fall to cognitive science、educational psychology,artificial intelligence,computer-aided education. In part of design,the paper gives fields knowledge representation,presents teaching strategy reasoning machine based on weight-generation production rule;according to cognitive learning theory,designes cognitive model of student which adopts approach method and historical inheritance of study,designs a teaching model which can navigate in learning process.In part of implementation, the paper studies implementation reasoning machine,and tries to give a preliminary implementation of ITS model.
