以知识点为核心的学习对象(LO)架构

Principle-knowledge Centered Learning Object

学习对象是实现资源重用与跨平台共享的有效途径,学习对象的粒度大小是决定学习对象重用共享的重要因素。基于面向对象的基本思想,结合课程教育的基本理念,提出以"知识点"为核心设计学习对象,并以《可视化程序设计》课程为例,基于我国现代远程教育学习对象元数据规范(CELTS-3),介绍了以知识点为核心的学习对象元数据库结构。

Learning object （LO） supplies an effective method to achieve the objectives of reusing and sharing instructional resource among different platforms. The granularity of a LO is considered as one of the most important factors to decide the reusing rate of a LO. Based on the foundational object-oriented theory and instructional thought, this paper introduced a principle-knowledge centered method to form a LO. Depending on the CELTS-3 Standard,it also provided an example of LO metadata for the course ＂Visual Basic Programming＂.
