摘要
智能教学系统是当前计算机应用的重要领域之一,文中主要研究在国家知识基础设施(NKI)支撑下的基于Web的智能教学系统模型:NKI Tutor。NKI Tutor包括七个模块:学生模型、教学模型、交互模型、NKI知识库、专家模型、出题模块和模拟工具,其主要特点是:(1)教学内容覆盖多个学科知识,且是动态的知识库;(2)交互模块给教师提供可操作的教学策略描述语言,便于教师在系统中设计个性化的教学策略。
Intelligent tutoring systems (ITS) have being extensively researched. This paper researchs Intelligent Tutoring Systems model based on Web:NKI-Tutor,which is built upon the National Knowledge Infrastructure (NKI) under construction. This model comprises seven modules:Student Model,Pedagogical Model,Communication Model,NKI Knowledge base,Expert Model,Exercise Module and Simulation Tools. The basic characteristic of it is that it is dynamic and covers the knowledge of lots of subjects. Besides, the Communication Model enables the teacher to design personalized teaching with exercisable describing language.
