摘要:已有研究表明自主学习能力是影响学生在线学习表现的重要因素。在线平台自动记录的海量学习日志数据,以及基于此数据发展起来的学习分析技术,为测量、理解、支持在线自主学习带来了新的机遇。近年来,大量研究开始探讨如何通过学习日志数据实时测量学习者的自主学习能力,以及如何利用平台测量指标还原学习者的自主学习过程有效甄别自主学习能力较差的学生。研究者们还利用平台数据开发面向学习者的学习分析反馈报告,用来帮助学习者更好地反思和改进自己的学习过程。虽然有研究已经取得了一定成果,但两个关键问题亟待解答:1)利用平台数据测量自主学习能力的效果如何2)基于学习分析反馈报告学习者的学习过程和学习成就产生怎样的影响以及通过何种机制产生该影响针对这些问题,本次报告将介绍两个利用学习分析技术支持在线自主学习的实证研究。第一项研究利用Canvas学习平台日志数据,构建学习者时间管理能力和学习力维持能力两方面指标,进而验证该两项指标的有效性;第二项研究采用随机试验方法,在本科课程中检验一种在线学习分析反馈干预对学习过程和学习成就的影响,并验证该项干预的影响机制。

The ability to regulate one’s learning is essential for success in online courses. Clickstream data, the detailed and real-time record of students’ interaction with the online platforms, provide new opportunities to measure, understand, and support students’ self-regulation in virtual learning. Recent efforts have used clickstream data to create timely, fine-grained, and comprehensive measures of self-regulated learning (SRL) behaviors in online courses in an attempt to shed light on the process of SRL and to improve the identification of students who lack SRL skills and are at risk of low achievement. Studies have also attempted to support students’ self-regulation in virtual learning environments using the clickstream data to provide students with learning analytics on their behaviors. However, key questions remain: to what extent do these clickstream measures correspond to traditional self-reported measures about specific SRL constructs? How effective are learning analytics interventions on student learning process and performance outcomes and what are the operating mechanisms? In this talk, I will discuss two studies that attempted to answer these questions. The first study used the clickstream data collected from Canvas to measure two aspects of SRL (i.e., time management and effort regulation) and triangulated clickstream measures with student self-reported data from before and after the course. The second study tested the effect of one learning analytics intervention on student outcomes and verified a proposed mechanism through a randomized controlled trial in a large online undergraduate course.
