摘要
随着信息技术的发展,在线学习成为学习者获取知识的一种重要方式,如何对在线学习进行有效评价成为备受关注的议题。区块链技术因其具有去中心、防篡改、可追溯等特性,塑造了坚定的“信任”驱动,成为引领第四次产业革命的关键技术之一。在此背景下,通过对比目前国内外在线学习评价模式,在深度分析区块链技术融入在线学习评价模式实现机理的基础上,针对在线学习评价中学生学习数据不真实和收集滞后等问题,设计一种基于区块链技术的在线学习评价模型,且引入第三方评价视角,使评价结果更具说服力。
With the development of information technology,online learning has become an important way for learners to acquire knowledge.How to evaluate online learning effectively has attracted more and more attention.At the same time,blockchain technology has become one of the key technologies leading the fourth industrial revolution because of its characteristics of decentralization,tamper resistance,traceability,etc.In this context.This paper analyzes and compares the advantages and disadvantages of current research on online learning evaluation mode at home and abroad,and designs an online learning evaluation mode based on blockchain technology on the basis of in-depth analysis of the implementation mechanism of online learning evaluation mode technology based on blockchain technology.This model solves the problems of the unreal and lag of online learning evaluation data collection,and introduces the third-party evaluation perspective so as to make the evaluation results convincing.
