【摘要】 该文对智能教学系统进行了深入的研究,提出了由用户环境和教学环境组成的基于web的智能教学系统形式化模型,并且对系统运行过程进行了详细的分析。该模型将本体论引入到领域知识的表示中提高了教学资源的重用和共享程度;同时,充分考虑了web以及用户环境所提供的与用户相关信息在智能教学系统中的重要作用。系统基于多领域多应用,结合认知能力、知识水平、学习风格、心理特征等知识结构和认知心理因素来对用户进行建模以增强系统的自适应能力和提高教学效果。更多还原

【Abstract】 In this paper,a formal model of a Web-based Intelligent Tutoring System (ITS) containing the user environment and the pedagogical environment is presented,which uses ontologies for domain knowledge representation to improve the sharing and reusing of pedagogical materials.Then the running process of the system is discussed in detail.The system constructs the user environment based on users’ cognitive abilities,knowledge levels,learning styles,psychology characteristics etc.,in order to improve the self-adaptability and pedagogical effects of the system.更多还原
