【摘要】 目前,远程教育的教学方式中应用最广泛影响最深远的是基于Web的远程教育,然而基于Web的多媒体计算机远程教学系统存在着系统智能性不高、系统的弹性与适应性不足等缺点。Agent技术提供了一种全新的、分布的计算模式和问题求解途径,将是下一代复杂分布的工程系统的模型。利用Agent技术,将个性化数字服务运用在远程教育中,是解决学生需求的个性化和教学资源的单一化这一矛盾的有效方案。本文通过分析传统远程教育系统模型的不足后创建了一个基于多Agent的智能远程教育系统模型。此模型由6个子系统构成,每个子系统又是由多个Agent组成的。此模型是利用Agent的协作机制来实现各模块间的信息交换与共享;还利用了Agent的智能推理能力来分析学生的个性特点,从而能够自适应地生成一个适合学生个体学习的教学策略,还能够智能地组织教学环节来引导学生更好的学习,使学生发挥出更大潜力。此模型采用了“主导+主体结合”的教学设计思想既发挥了远程教育中教师的主导作用,又充分体现了学生的认知主体作用。在本文所建立的远程教育系统模型中,学生学习子系统模块是最为重要的,它是其它子系统能够正常运行的基础。针对目前大多数关于学生模型的研究不是复杂且难以实现,就是简单但推理能力弱的现状,本文创建了一个多Agent的学生模型。此模型采用模糊推理与概念图相结合的方法不仅推理能力强,而且容易实现。本文以软件工程理论和面向对象程序开发方法为基础,构建了三层结构的远程考试管理系统模型,其具有安全性、稳定性和实用性等特点。更多还原

【Abstract】 Now, the web-based distance education is used most widely in the education method of distance education. While the web-based multi-media computer’distance education system has many defects. It has not enough intelligence, defects such as systematic resilience, elasticity and so on. Agent technique provide one kind of the new, distributed calculation pattern and problem resolution method, it will become the next generation system pattern of the complex distributed project system. Using agents in distance education, we will get the individual digital service, it is the effective method to resolve the contradiction between students’ individual demands and singleness of education resource.After analyzing the deficiencies of distance education system models, this paper establishs a mufti-agent based intelligence distance education system model. The model is made up of six modules and each module includes a few agents. Utilizing the cooperative mechanism among agents, the model realizes information exchange and share among the modules; Utilizing agent intelligent reasoning ability, the model can learn characteristics of student personality, adaptively build a sort of teaching strategy which adapts to student, intelligently organize teaching process and lead student to study better and to exert more potential. In addition, the designing ideas of the model not only bring a leading role of teacher into play but also fully reflect cognitive main body of student. This model adopted the teaching design thought of"predominance+ the corpus combine" since develop the teacher’s predominant function in the long range education, again the full body was now the student’s cognition corpus function.The key module in the model mentioned above is student’s studying the sub- system model, which is basis for other modules to well work. However, now most of related researches are too complex to realize or easily implement but have little reasoning ability. Aiming at this kind of condition, the paper puts forward a multi-agent student’s studying the sub- system model. This model adoption faintness reasons logically to combine together with the concept diagram of method not only reason logically an ability strong, and easy realization.This paper with the software engineering theories with face to the object procedure development method for foundation, set up three layer the distance examination of the structure management the system model, it has characteristicses,更多还原
