摘要
技术的飞速发展以及校园网络的建立,拓宽了学生学习的渠道。网络教学这种不受
空间和时间约束的教学方式得到了越来越广泛的应用;然而,现有的网络教学系统存在智能性较
差、动态交互功能不强、不能根据学生的认知水平和学习情况调整教学策略、缺乏有效引导等问
题。
本文在分析了国内外研究现状的基础上,对智能导学系统、智能 Agent、Agent 间的通信、
多 Agent 系统开发平台等相关理论与技术进行了探讨。论文针对现有网络教学系统存在的不足,
将多 Agent 技术与智能导学系统的需求紧密结合,设计了以建构主义理论为理论基础、综合利用
教育学及计算机科学等多门学科成果的智能导学系统。论文结合 CSLS 模型和 Agnieszka
Landowska 的三层管理思想,提出了本系统的学生模型结构;对认知水平评价模型进行了完善;
综合考虑了常用的获取学习偏好的途径,提出了本系统获取学习偏好的方法。
在分析、设计的基础上,结合 JADE 平台与 J2EE 技术构建了一个基于 B/MA/S 三层结构的
智能导学系统,实现了《计算机文化基础》智能导学系统的原型。测试的结果表明,与现有的网
络教学系统相比,该智能导学系统的智能性有所提高。

ABSTRACT
The development of the and the construction of works have led to the
broadening of channels for learning. Free of the constraints of time and space, E-learning is being used
more and more widely as an educational method. There are, however, notable ings in
E-learning systems. First, these systems lack intelligence, and dynamic interaction between users and
these systems is weak. Second, these systems do not have the flexibility to adjust teaching strategies to a
student’s particular cognitive level and educational situation. Third, these systems lack effective
guidance.
Based on research at home and abroad in this field, this paper presents a discussion of various
theories and technologies, which include ITS, Intelligent Agent, munication, and the
developing platform of Multi-Agent System. Aimed at addressing defects of work teaching
systems, this paper designs an intelligent tutoring system based on the Constructionist Theory, using
advancements in the fields of Education puter Science. This bines technology from
the Multi-Agent System with the requirements of intelligent tutoring systems. Integrating the CSLS
Model with the 3-level management ideas of Agnieska Landowska, this paper proposes the student
model, one that is based on the student’s cognitive level
