  【摘要】 随着计算机技术和网络技术的不断发展和普及,代表着先进的教学思想和教学方法的智能计算机辅助教学(Intelligence Computer-Assisted Instruction,ICAI)应运而生,它改变了传统CAI模式化、机械化的教学方式,为学生提供了一种新型的双向式教学环境。ICAI将教学内容与教学策略分开,根据学习资源库提供的学生模型,通过智能系统的搜索与推理,动态生成适合于个别化教学的内容与策略;通过智能诊断机制判断学生的学习水平,分析学生产生错误的原因,提供合理的改进方案,同时修改原来的学习策略,为教师对教学内容的调整改进提供依据。本文从ICAI系统实际需求出发,首先阐述了智能教学系统的理论基础和开发原理,然后在基于Web的ICAI系统基础上,研究了系统的教师模块、学生模块、管理模块等各个模块模型的构建,在上述三大模块及相关基本数据模型基础上,给出了系统的总体和具体的框架结构设计方案,系统在设计实现上主要采用了Scorm数据标准,集合多媒体、网络和Web技术,综合运用了Prolog语言、浏览器/服务器、Internet信息服务等众多现代软件设计方法、开发模型模式、技术技巧和最新的开发工具。本文最后深入讨论并解决了系统的重点难点:基于可信度的不确定性推理方法的使用;Scorm数据模型的应用;用概念图的知识表示实现知识诊断;认知型学生模型的建立;模糊综合评价学生水平;教师教学策略的正反向推理以及使用改进的遗传算法实现智能组卷。该系统对于突破教学在时间和空间上的限制性,实现教师“教”与学生“学”的实时互动性和协作性、教育资源的共享性都具有深远的意义,充分体现了网络教学的互动、开放、智能、自适应的特点。

  【Abstract】 With the continuous development and spread of the technology of the computer and network, the methods ICAI(Intelligence Computer-Assisted Instruction) representing the advanced teaching ideas are emerged as the times require. It changed the traditional CAI teaching way of hipping and mechanized, and provided a new two-way teaching environment to the students.The ICAI has separated the teaching content from the teaching strategies, generated the contents and strategies suitable for individual dynamically according to the student model provided by the learning resource library and the search and reasoning of the intelligent system; based on the intelligent diagnosis system to determine the level of student learning, analyze reason of the students have made, give reasonable improving programs, modify the original learning strategies, and provide basis for the adjusting of the teaching contents by the techers.The paper from the real needs of the ICAI system, firstly, the paper describes the theoretical basis and development principle of the intelligent teaching system, then based on the ICAI systems of the Web to study the structure of the teacher module, student module, management module and other modules. Base on the above three modules and related basic data model, the paper gives the whole and specific design planning of the frame structure of the system. The system mainly adopts Scorm data standard, collective multimedia, internet and Web technique in design realization, and comprehensively utilizes many modern software design methods, developing models and modes, techniques and skills and the latest developing tools such as Prolog language, browser or server, Internet information service and so on.This paper at last deeply discusses and solves the important and difficult points of the system: the utilization of reasoning method of uncertainty based on reliability; application of Scorm data models; using the knowledge of concept map to indicate realizing knowledge diagnosis; the establishment of cognitive-type student models; evaluating students’level vaguely and comprehensively; forward and backward reasoning of teachers’teaching strategies and using improved genetic algorithm to realize intelligent test paper.The system profound significance in breaking through the limits of time and space in teaching, realizing the interactivity and cooperation of s teachers’teaching and students’learning,also sharing of teaching resource.
