摘要
学习资源库是基于Web学习环境中的重要组成部分,针对现有学习资源库服务的不足,文章提出了学习资源库知识服务模型,系统的论述了学习资源库知识服务的类型、服务提供方式、构成要素、工作机制以及服务过程等,提出了以Agent为主要实现技术的学习资源库知识服务系统框架,为验证此模型与框架的有效性与可行性,构建了实验系统。实验结果表明知识服务的提供能够有效的提高学习资源库的利用率、教与学效果以及学习资源管理效率。
Learning Object Repository(LOR) is a very important component of Web-based learning environment.To overcome the shortages of traditional services provided by LOR,in this paper a knowledge service model of LOR is proposed.According to this model,a framework of agent-based LOR system providing knowledge services is suggested.To prove the validity and feasibility of this model,a test system is developed.And the test result indicates that the providing of knowledge service of LOR can improve the utilization of LOR and the performance of teaching and learning based on LOR,and also improve the efficiency of the management of LOR.
