【摘要】 伴随着信息技术的蓬勃发展，网络教学正在全面兴起。通过各种措施来提高网络远程教学的质量正逐步成为教育技术界研究人士倍受关注的主题。系统的网络教学多以网络课程的形式进行。但是，当前国内在网络课程资源的开发建设中却存在着许多混乱不足之处。对此，本文引出一个正在国际教育技术研究界逐渐流行的术语——“学习对象(Learning Object)”，以此作为研究网络课程开发的切入点和创新之处。 学习对象是一种可重用的数字化教学构件，作为面向对象的计算机科学思想在教育技术领域中的方法延伸，它有着极高的实用价值和广阔的应用前景。本文在参阅大量国外文献的基础之上，首先细致而系统地研究了学习对象的概念特点、思想来源、理论基础；接着剖析了学习对象的粒度分类和编列理论两大主题，并进而就其在网络教学中的应用价值和实例进行了阐述说明；随后，本文将学习对象与LOM(Learning Object Metadata Standard：学习对象元数据标准)相结合，构造了一个基于LOM的新型网络课程系统模型(LOMWS：LOM-based Web-course System)。该系统利用XML技术来实现LOM，并具有实施个性化课程编列等功能。最后，本人开发试行了该系统的演示版本，并对研究工作做出了小结。更多还原

【Abstract】 With the vigorous development of IT, the tide of distance learning is coming. How to improve the quality of distance learning by various means has become a common concern in the domain of Educational Technology. Usually the systematic distance learning is performed in the form of web-course. However, there are common shortcomings during the process of developing the instructional materials of web-courses nowadays. This paper introduces a new term named "Learning Object"(LO) that is prevailing in the domain of distance learning worldwide, and uses it as an innovative key element for the development of the web-based courses.Learning Object represents a sort of reusable digital instructional component, which is reusable, sharable. and it can be aggregated, sequenced, and tagged by metadata. Being a new type of instructional component, which grounded in the object-oriented paradigm of programming, LO has great values of application. Based on the analysis of a lot of literatures, this paper systematically goes into research on the theory of LO, including its concept, features, origin, theoretical basis, granularity, taxonomy, sequence, and further discusses the values and samples of LO’s applications in distance learning. Following, this paper combines the LO and LOM (Learning Object Metadata Standard) to construct a platform model named LOMWS (LOM-based Web-course System) which uses XML to realize LOM and can function as course sequencing for individual learning. In the last part, this paper describes a prototype of LOMWS, followed by some conclusions resulted from the research mentioned above.更多还原
