面向学习对象课程群模型的构建

为了开发<信息安全>课程群智能辅助教学系统和满足网络环境下的多元化教学要求,提高学习效率,在研究学习对象及其相关标准的基础上,设计了一种基于集教学内容、教学设计和教学活动于一体的学习对象的课程群构建模型.首先根据岗位能力需要把课程群递归定义成课程群、岗位能力和知识点三个层次的学习对象,知识点为最小学习对象;然后结合学习对象元数据、学习设计和内容包装规范对各层次学习对象的定义内容包装;最后采用领域本体技术对课程群建模,定义领域内的概念及其相互关系与实际的课程群资源间的映射,并基于XML技术绑定.该模型中每层学习对象内部均含有描述学习活动的教学设计,这使学习对象增加了教师特性,并能同时为多个学习者分别创建学习情境、提供个别指导.

THE MODEL CONSTRUCTION FOR LEARNING-OBJECT-ORIENTED CURRICULUM GROUP

For exploring an intelligent computer-aided instruction system for the curriculum group of Information Security,meeting the diverse teaching demand in network condition and improving the learning efficiency,the construction model for curriculum group of learning object was designed which integrated the content,design and activity related to teaching.Firstly,recursively defined the curriculum group to three levels' learning objects according to the need of position ability;they are curriculum group,position ...
