活体教育实验平台的使用与设计

Using and Designing Platforms for In Vivo Education Experiments

Joseph Jay Williams, Korinn Ostrow, Xiaolu Xiong, Elena Glassman, Juho Kim, Samuel G. Maldonado, Na Li, Justin Reich, Neil Hefferman

摘要:

与典型的实验室实验相反,大量人群每天使用在线教育资源,以及A/B测试软件基础设施的普及,使我们考虑平台如何嵌入体内实验,不仅支持研究,而且确保其教育组件的实际改进。本文介绍了作者在三个广泛使用的在线教育平台Khan Academy、edX和ASSISTments中进行的随机实验比较的例子。我们提出了平台技术的设计原则,以支持随机实验,从而实现迭代改进和协作工作的实际改进,并解释了WPI共同作者在ASSISTments平台上实施的好处。

英文摘要:

In contrast to typical laboratory experiments, the everyday use of online educational resources by large populations and the prevalence of software infrastructure for A/B testing leads us to consider how platforms can embed in vivo experiments that do not merely support research, but ensure practical improvements to their educational components. Examples are presented of randomized experimental comparisons conducted by subsets of the authors in three widely used online educational platforms Khan Academy, edX, and ASSISTments. We suggest design principles for platform technology to support randomized experiments that lead to practical improvements enabling Iterative Improvement and Collaborative Work and explain the benefit of their implementation by WPI co-authors in the ASSISTments platform.
