关于智能辅导系统（ITS）的开发已经做了很多研究，小型实证研究已经证明了ITS在促进学生学习方面的有效性。然而，在学校环境中大规模实施ITS还没有得到深入的研究。在本文中，我们描述了一项正在进行的随机对照试验（RCT），以评估基于网络的辅导系统- assistments -作为家庭作业支持的有效性。该项目在缅因州的46所中学使用，为学生提供即时反馈，并向教师提供报告，以支持家庭作业审查和教学适应。我们描述了RCT面临的挑战，用于理解系统实现的方法，以及如何使用系统的发现。
Much research has been done on the development of an intelligent tutoring system (ITS), and small empirical studies have demonstrated the effectiveness of ITS at promoting student learning. However, large-scale implementation of ITS in school settings has not been researched thoroughly. In this paper, we describe an ongoing randomized controlled trial (RCT) to evaluate the efficacy of a web-based tutoring system—the ASSISTments—as support for homework. The program is used in 46 middle schools in the state of Maine, to provide immediate feedback to students, and to provide reports to teachers to support homework review and instruction adaptation. We describe the challenges for the RCT, approaches used to understand implementation of the system, and findings on how the system is being used.
