摘要

快速反馈是精通学习的核心组成部分,但在今天的大多数课程中,开放式作业的反馈需要几天或几周的时间。本文介绍了PeerStudio,这是一个评估平台,它利用在线课程中大量学生的同龄人来实现对正在进行的工作的快速反馈。学生提交他们的草稿,对两个同学的草稿给出基于规则的反馈,然后收到同学的反馈。学生可以整合反馈,并按照自己的意愿重复这个过程。在MOOC部署中,学生收到反馈的平均时间是20分钟。对正在进行的作业的快速反馈提高了课程效果:在一项对照实验中,当反馈快速传递时,学生的最终成绩会有所提高,但如果延迟24小时则不会。超过3600名学生在8堂课上使用了PeerStudio,包括大规模的和面对面的。这项研究证明了大班是如何利用他们的规模,通过快速的反馈和修改来鼓励学生精通的。

PeerStudio: Rapid Peer Feedback Emphasizes Revision and Improves Performance
Rapid feedback is a core component of mastery learning, but feedback on open-ended work requires days or weeks in most classes today. This paper introduces PeerStudio, an assessment platform that leverages the large number of students' peers in online classes to enable rapid feedback on in-progress work. Students submit their draft, give rubric-based feedback on two peers' drafts, and then receive peer feedback. Students can integrate the feedback and repeat this process as often as they desire. In MOOC deployments, the median student received feedback in just twenty minutes. Rapid feedback on in-progress work improves course outcomes: in a controlled experiment, students' final grades improved when feedback was delivered quickly, but not if delayed by 24 hours. More than 3,600 students have used PeerStudio in eight classes, both massive and in-person. This research demonstrates how large classes can leverage their scale to encourage mastery through rapid feedback and revision.
