本文描述了一类新的智能教学系统，我称之为学习伙伴系统。在这样一个系统的学习环境中，有三个代理参与，即，人类学生，计算机学习伙伴，和计算机教师。顾名思义，计算机学习伴侣的作用是充当学生的学习伴侣。为此，同伴在与学生大致相同的水平上执行学习任务，并且学生和同伴在由教师呈现相同材料的同时交换想法。在设计LCS的原型Integration-Kid时，在集成领域，我定义了三个Agent之间的学习活动协议。这些协议反映了学习者在学习过程中的不同学习阶段，并适当地限制了他们可能的无界交互。设计了一种基于领域结构的课程树体系结构作为Integration-Kid的实现框架。产生式系统通过一个共同的黑板来模拟不同代理的交互。对于同伴和老师来说，问题解决器的基础是一个术语重写系统。最后，总结了本人设计的样机和LCS总体上存在的不足，并对LCS相关研究的未来方向进行了讨论。
This thesis describes a new class of Intelligent Tutoring Systems (ITS) which I call the Learning Companion Systems (LCS). In the learning environment of such a system, there are three agents involved, namely, the human student, the computer learning companion, and the computer teacher. As implied by its name, the role of the computer learning companion is to act as a learning companion for the student. To this end, the companion performs the learning task at about the same level as the student, and both the student and the companion exchange ideas while being presented the same material by the teacher. In designing the prototype of LCS, Integration-Kid, in the domain of integration, I define some protocols of learning activities among the three agents. These protocols reflect the different learning stages of the learners in the learning process as well as appropriately restrict their possible unbounded interactions. Curriculum Tree, an architecture based on the domain structure is designed as the implementation framework of Integration-Kid. Production systems are used to simulate different agents' interactions via a common blackboard. The basis of the problem solver for both the companion and the teacher is a term rewriting system. Finally, the disadvantages of my design of the prototype and LCS in general, and the future directions of LCS related research are discussed.
