Abstract: In an intelligent tutoring system there are many instruction patterns is very important. Meanwhile, it is difficult in constructing an ITS with instruction patterns. This paper describes some concepts of component and the relations between components firstly, using component technology then we propose a component model of ITS with instruction patterns. In this system, all kinds of instruction patterns can be existed as components independently. So the system can realize the personalized instruct

摘要： 智能教学系统中存在多种教学模式对提高系统的适应性教学是非常重要的，然而建构这样的系统却比较困 难．本文通过对构件技术的分析，提出了多模式智能教学系统的构件模型．在基于构件技术的多模式智能教学系统 中，各种教学模式、教学决策和学生模型都独立出来形成构件，通过运用教学模式构件的安装和卸载来构成具有不 同教学模式的智能教学系统，以实现网络教学的个性化和智能化，方便系统的升级与维护
