数字教育资源建设的生态化视角及技术架构

Building and Sharing Digital Educational Resource from an Ecological Point

数字教育资源建设的相关理论及实践是教育信息化领域的研究热点。为了更好地解决数字教育资源建设及共享问题，本文从生态化视角梳理了数字教育资源建设和共享过程，构造了数字教育资源生态化建设和共享理论框架，建立了数字教育资源的建设生态、共享生态与共建共享生态模型，进而深入研究各生态模型涉及的各种要素、对应关系及运作机制;同时，引入Web2. 0 及云技术，勾绘了生态化共建共享的技术架构，为数字教育资源建设的可持续发展提供了可行的技术路线。

The theory and practice in constructing digital education resources continue to be an interest in the field of educational technology. In order to better solve the problem of building and sharing useful digital education resources, this article tries to figure out the processes of building and sharing digital education resources from an ecological view, so as to present an ecological theory framework with three ecological models, and the essence, relationship, and mechanism of each model. Based on the theoretical models, a technological architecture that can provide a feasible technology solution for sustainable development of digital education resources is outlined.
