【摘要】 教育资源建设是教育信息化的基础,是需要长期建设与维护的系统工程。课程资源是教育资源的重要组成部分,构建可重用性高、互操作性好的标准化课程资源是教育信息化中重要的一环。本论文通过对课程群结构、学习对象技术、学习设计规范、XML技术、领域本体和RDF资源描述框架的研究分析,结合国际和国内教育行业的教学现状提出了一个层次化的课程群构建框架。在整个框架中引入学习对象概念,将每一层都看成是学习对象,并把底层的知识点定义为最小学习对象,它包含40±5分钟的学习内容,而将高层定义为复合型学习对象,尝试借助学习对象的特性来提高课程群知识的重用性、互操作性,尝试借助学习设计把教学内容与教学方法有机结合,以提高学习对象的教学功能。课程群框架通过采用学习对象、学习设计规范、领域本体等技术,运用XML语法把课程群知识表示成具有规范结构和通用的文本文件,从而达到灵活机动的构建教学所需的可重用性高、互操作性好、针对性强、易于更新、易于组织的课程群的要求。本论文介绍了课程和课程群的概念、ICAI系统的设计思想,并给出了两个应用课程群框架的试验示例,试验结果表明文中提供的框架是实用而有效的,为智能辅助教学系统的功能设计与开发提供了有价值的参考。更多还原

【Abstract】 Teaching resources construction is not only the basis of education informatization but also a systematic project needing long-term construction. Curriculum resources are the important constitution of teaching resources. It is indispensable to construct the standardized curriculum resources with high reusability and operability to education informatization.Through the research and analysis on curriculum group structure, learning object technology, learning design standard, XML technology, realm corpus and framework of RDF resources description, a framework of curriculum group construction is put forward. In this framework, the concept of learning object is introduced, each layer is regarded as learning object, and the bottom knowledge points are defined as the minimum learing objects which include 40±5 minutes learning contents, and the other layers are defined as composite learning objects which try to improve the reusability and mutual operability of curriculum group knowledge through the characteristics of learning objects and which try to combine teaching contents and teaching methods through learning design in order to improve the teaching function of learning objects.Adopting such technologies as learning object, learning design standard and realm corpus, curriculum group framework uses XML grammar to represent curriculum group knowledge into common text file with standard structure to meet the construction requirement of curriculum group with high reusability, great mutual operability, strong relevance and easy innovation and organization.This paper introduces the concepts of curriculum and curriculum group, the design idea of ICAI system, and presents two experiments and illustrations of practical curriculum group framework. The experiments show that the framework provided in the paper is practical and effective, which provides beneficial reference for the functional design and development of intelligent assisted teaching system.更多还原
