摘要
如何对网络开放课程中的海量学习数据进行采集、存储、分析与表示,并利用分析结果做出决策、优化学习、提高绩效,日益成为亟待解决的问题。NMC地平线报告中介绍的学习分析技术有助于这一问题的解决。根据我国开放课程的现状与学习分析法的特征,开放课程环境下学习分析的研究对象与服务对象具有一定的特殊性。学习分析模式包括采集、存储、分析、表示与应用五个层级;建模时需充分考虑数据与利益相关者的特殊性。未来,学习分析模式的应用在理论基础、数据标准、算法模型、隐私与安全性等方面面临着挑战。
It has been an urgent issue that how to collect ,save,analyze and present the massive data in open online courses ,and make decision based on the analyses in order to optimize learning strategy and improve performance .The technology of learning analytics in NMC horizon reports has contributed to solving this problem .Base on the situation of open courses in our country and the features of learning analysis ,there are some particularities in research object and service object of learning analysis in open courses.The learning analysis mode consists of five levels of collecting ,saving,analysis,presenting and application .The particu-larities of data and stakeholders should be fully taken into consideration in the course of modeling .The application of this model will face challenges in theoretical basis ,data standards ,algorithm models ,privacy and security .
