Abstract:

学习分析目前应用于教育的多个方面,但是还缺乏一个完整、清晰、可实施的学习数据系统.本文尝试构建一个开放的、全面的学习分析系统.综述了该领域研究近年的发展,并对若干重要概念进行了定义,给出了学习分析系统和数据的时空与交互演化.着重分析了学习分析系统论域(LASUoD)、形式化建模学习分析系统信息空间模型[ΣR,ΣCR,ΣMT,ΣA,ΣW,ΣC],构建了学习分析系统架构,并分析了该系统中数据流程.提出了学习分析对象数据模型、学习分析系统本体(LASO)框架及学习分析系统标准组谱,以实现学习分析系统应用的互操作.最后,为了说明学习分析系统应用情况,展示了一个基于开源学习管理系统Sakai的学习分析实例.
