摘要
对IMS学习设计规范中的学习目标进行了分析,并构建其概念模型,然后运用描述逻辑语言ALC对该模型进行形式化描述,定义了学习目标的相关概念,并通过不同的权值来表现对不同知识点掌握的高低程度。
Iearning objective in IMS Learning Design is analyzed, and the conceptual model has been built. The model in description language ALC is described, and defined the relative concepts of learning objective, and also different weight reflected the different knowledge degrees.
