摘　　要：把基于案例推理(CBR)技术引入智能教学系统中教学策略的推理和控制中,提出了在全局教学策略和局部教学策略控制中CBR应用模型,并提出了在这种模式下,案例库的初始化、案例的学习与修正方法。该模型应用以前学生学习的经验作为以后学生学习的引导,从而实现教学策略的自动组织、自动规划,实现学生的自主选择,自由学习。最后进行了总结,提出了下一步研究的方向。The CBR technology into the teaching strategy inference and control of intelligent tutoring system is integrated, a CBR application model in the overall instruction strategy and the local instruction strategy control is proposed, and case database initialization, case study and revision method are proposed. This model uses learning experience of previous students to guide future students to learn, it accesses an antomatic organization and planning mechanism ofinstruction strategy, and makes students achieve the freedom of Learning materials＇ choosing and study, Finally the summary is given, the future study direction is proposed.
