基于元数据的教学资源存储管理

Study on Storage and Management of Learning Resources Based on Metadata

针对教学资源建设管理中存在的问题,根据学科知识体系结构、人的认知规律和教学规律的内在统一性,提出对教学资源进行粗粒度划分,采用元数据对原子资源进行描述,建立远程教育支持平台,对教学资源进行松散结构化存储管理。此方法屏蔽了不同资源内容上的多样性和差异性,提高了资源的有效共享和整合重组能力,为满足用户个性化资源需求提供方便。

According to the intrinsic unity of knowledge architecture, human＇s cognition rules, and learning and teaching rules, this paper proposed to segment teaching resources into coarse grain atomic resource, to describe the atomic teaching resource by metadata, and to establish distance learning support platform using loose and structured architecture to manage the teaching resources, aiming to solving the problems in teaching resources management. In this way, the diversity and differences of teaching resources can be shielded, the ability to share and to reorganize resources can be enhanced, so as to provide convenience to satisfy individual demand for teaching resources.
