摘　　要：大规模数据模型是国家教育数字化服务平台建设应用科学化和精准化的基础,也是解决当前“互联网+教育”生态下的教育数据难以重用、互操作性差、重复建设、数据孤岛等问题的关键。如何组织和构建可重用的教育数字化服务平台的教育数据模型体系,从而增加教育数据模型的灵活性和可扩展性,减少教育数据模型重复建设,是当前亟待解决的基础性问题。因此,以学习对象为基础提出教育数据对象,并基于教育数据对象构建可重用的教育数据模型体系,明确具体的操作机制,形成面向教育数字化服务的教育数据模型体系构建过程。基于此,进一步确定模型体系的层级组织结构,探析其共享通信机制,并通过案例分析,呈现模型体系的应用过程,实现区域教育数字化服务平台间教育数据模型的互联互通和可重用。The large-scale data model is the basis for the scientific and precise application of the construction of the national education digital service platform,and it is also the key to solving the problems of difficult reuse,poor interoperability,repeated construction,and data silos under the current“Internet+education”ecology.How to organize and build a reusable education digital service platform education data model system,so as to increase the flexibility and scalability of the education data model,and reduce the repeated construction of the education data model,is a fundamental problem that needs to be solved urgently.Therefore,an educational data object is proposed based on the learning object,and a reusable educational data model system is constructed based on the educational data object,the specific operation mechanism is clarified,and the construction process of an educational data model system oriented to educational digital services is formed.Based on this,the hierarchical organization structure of the model system is further determined,its shared communication mechanism is analyzed,and the application process of the model system is presented through case analysis,so as to realize the interconnection and reusability of education data models between regional education digital service platforms.
