【摘要】：在基礎(chǔ)教育領(lǐng)域,數(shù)字教育資源的建設(shè)與應(yīng)用經(jīng)過了多年的發(fā)展,正逐步深入。但是,依然存在優(yōu)質(zhì)資源數(shù)量匱乏,結(jié)構(gòu)單一,應(yīng)用不方便的問題,主要原因是尚未形成數(shù)字教育資源共建共享的長效機(jī)制。目前,國家已經(jīng)提出優(yōu)質(zhì)教育資源班班通的發(fā)展目標(biāo),那么如何利用信息技術(shù),構(gòu)建數(shù)字教育資源的技術(shù)平臺以有效解決共建共享的問題,以及從區(qū)域應(yīng)用發(fā)展的角度開展此方面的建設(shè)研究,具有重要的應(yīng)用價值。區(qū)域數(shù)字教育資源的共建共享,核心的問題是如何構(gòu)建一個方便的技術(shù)平臺,并輔之以有效的激勵策略[1]。技術(shù)平臺的架構(gòu)要解決各級教育部門、學(xué)校、教師對資源建設(shè)與應(yīng)用的需求。即資源的上傳、審核、入庫、訪問權(quán)限控制、評優(yōu)推薦、各級資源庫的對接、應(yīng)用共享服務(wù)聚合等。由此提出資源共建共享的基本框架模型和平臺的架構(gòu)設(shè)計(jì)；在系統(tǒng)實(shí)現(xiàn)中各級資源平臺分層對接,資源庫按分布式部署,應(yīng)用功能按需擴(kuò)展；為實(shí)現(xiàn)平臺應(yīng)用功能的動態(tài)擴(kuò)展機(jī)制,通過研究選擇以O(shè)Auth標(biāo)準(zhǔn)構(gòu)建開放接口,并作為與第三方平臺對接的技術(shù)方案,且完成了技術(shù)實(shí)現(xiàn)；最后,為保證資源共享和各資源庫間互操作,對數(shù)字教育資源庫建設(shè)提出了資源分類標(biāo)準(zhǔn)和數(shù)據(jù)規(guī)范,資源分類標(biāo)準(zhǔn)將文字、圖片、動畫及微課等新媒體納入其中,提出了涵蓋數(shù)據(jù)存儲標(biāo)準(zhǔn)、資源基本分類、元數(shù)據(jù)結(jié)構(gòu)、資源類型設(shè)計(jì)框架等數(shù)字教育資源標(biāo)準(zhǔn)和數(shù)據(jù)規(guī)范。區(qū)域數(shù)字教育資源建設(shè)研究,從平臺功能需求、區(qū)域資源整合技術(shù)、數(shù)字教育資源分類標(biāo)準(zhǔn)三個方面開展了分析和研究。在陜西省的相關(guān)項(xiàng)目中,該技術(shù)框架和資源庫標(biāo)準(zhǔn)應(yīng)用于實(shí)踐,已取得了一定的成效,并將應(yīng)用效果中出現(xiàn)的問題,作為下一步研究和解決的重點(diǎn)方向。
[Abstract]:In the field of basic education, the construction and application of digital education resources have been developed for many years and are gradually deepening. However, there are still the problems of lack of high quality resources, single structure and inconvenient application. The main reason is that the long-term mechanism of digital education resources co-construction and sharing has not been formed. At present, the country has put forward the development goal of quality educational resources, so how to make use of information technology to build a technology platform for digital education resources to effectively solve the problem of co-construction and sharing. And from the perspective of regional application development to carry out this aspect of the construction research, has an important application value. The core problem of the joint construction and sharing of regional digital education resources is how to build a convenient technical platform with effective incentive strategies [1]. The structure of the technology platform should meet the needs of education departments, schools and teachers for resource construction and application at all levels. That is, resources upload, audit, database, access rights control, evaluation and recommendation, the docking of resources at all levels, application sharing service aggregation and so on. Therefore, the basic framework model and architecture design of resource co-construction and sharing are put forward, and in the realization of the system, all levels of resource platform are layered and docked, the resource base is distributed deployed, and the application function is expanded as needed. In order to realize the dynamic extension mechanism of platform application function, the open interface is constructed by OAuth standard, which is used as the technical scheme of docking with the third party platform, and the technical realization is completed. Finally, in order to ensure the sharing of resources and the mutual operation of each resource bank, the paper puts forward the resource classification standard and data standard for the construction of digital education resource bank. The resource classification standard includes new media such as text, picture, animation and micro-class. The standard and data specification of digital education resources including data storage standard, basic classification of resources, metadata structure, design framework of resource type and so on are put forward. The research on the construction of regional digital education resources has carried out analysis and research from three aspects: the platform function demand, the regional resources integration technology, the digital education resources classification standard. In the relevant projects of Shaanxi Province, the technical framework and the standard of resource base have been applied to practice, and some achievements have been made, and the problems in the application effect have been regarded as the key direction of further research and solution.
