应用区块链技术构建开放教育资源新生态

Using blockchain technology to create a new ecology of OER

区块链技术是基于去中心化、去信任的方式共同维护一个可靠数据库的技术方案。该文利用区块链技术的独特优势构建开放教育资源新生态,解决当前开放教育资源建设面临的运营成本高、版权保护弱、资源共享难和资源质量低等现实问题,以适应智慧教育时代对资源开放共享的新要求。以区块链技术为底层技术构建的开放教育资源分布式管理平台包括用户管理中心、资源创作中心、资源管理中心、版权管理中心、虚拟币交易中心和学习证书管理中心六大核心系统,用以促进开放教育资源发展。由于区块链技术的不成熟和教育领域的复杂性,文章总结了区块链技术在开放教育资源建设中面临的资源流转低效、存储空间有限和用户隐私泄露等挑战,并对未来研究方向进行了展望。

This article takes advantages of the uniqueness of blockchain technology to create a new ecology of Open Educational Resources(OER) in order to overcome problems such as high operational costs, insufficient copyright protection, barriers to sharing resources, and poor resource quality, fulfilling the new demands on opening up and sharing resources in the era of smart education. An OER Distributed Management Platform using blockchain as its underlying technology is composed of six core systems, namely user management center, resource creation center, resource management center, copyright management center, virtual currency exchange center, and learning certification management center. These systems are intended to facilitate OER development. It is also pointed out that due to its immatureness and the complexity of the educational sector, blockchain technology faces challenges such as low efficiency in resource circulation, limited storage space and possible privacy leaks. Directions for future research are also discussed.
