Abstract
To manage the educational resources of the grid community based on the standard of learning object metadata, the resource classification standard of the learning object metadata standard is taken as the basis of the grid community division. According to the principle of the classification of educational resources, and based on the characteristics of the grid management system and the features of the grid community, the construction and internal structure of grid community are discussed, and the idea of constructing peer community group is proposed. In accordance with the idea of peer community, similar educational resources achieve a logical connection between peer communities. The results show that the mechanism of information sharing and information diffusion is established among communities, and the framework of educational resource management is constructed through simulation and evaluation.
Highlights
Educational resources refer to teaching materials, courseware, reference materials, teaching standards and process specifications used for teaching process and its evaluation and management
LOM will be used as metadata standard for the reference standard of educational resource grid community
Since the community is the basic unit of teaching resource management, sharing and publishing, and retrieval, the formation of the community is a core issue
Summary
Educational resources refer to teaching materials, courseware, reference materials, teaching standards and process specifications used for teaching process and its evaluation and management. Educational resources have many characteristics, such as large amount of data, various forms, strong pertinence and strong education. The construction and management of educational resources in China are mainly carried out in the form of campus network resource system, regional education resource system, and educational backbone network resource system. There are still some problems in the management of educational resources: information island, search difficulties, and sharing difficulties. It is one of the important issues faced by the educational information how to integrate scattered and disordered educational resources, so that users can and efficiently use them in their own learning and work, and achieve sharing in a large scope
