Improving learning in K-12 Science, Technology, Engineering, and Mathematics (STEM) is a critical national need as more jobs require STEM proficiency. Recently, Intelligent Tutoring Systems (ITSs) have shown great promise in improving STEM learning in middle school and high school. While these tutors support students directly, they do not provide information to teachers. This project will remedy this shortcoming by developing software that will display the students' progress in middle school mathematics and will also suggest help that the teacher can provide to the students to enhance their learning. The help that the software provides is based on the analysis of learning built into the tutor, but which is too complex to be usable by teachers.This project will take a user-centered design approach to create a teacher's dashboard for ITSs, so that it can be effective in various realistic classroom scenarios. Classroom studies will be conducted to evaluate whether, when used by the teacher, the dashboard helps students learn more effectively. The work will focus on Mathtutor, a freely available website with intelligent tutoring software for middle-school mathematics learning. Specifically, the project will focus on Lynnette, a tutor for grades 7 and 8 with a proven track record in helping students learn to solve linear equations. The research questions to be addressed include: What is the up-to-the-minute data about student learning that intelligent tutoring systems can provide that is helpful to teachers and how can it best be presented in an actionable manner?How do teachers use actionable analytics presented in a dashboard to help their students?Do students learn better when their teacher monitors a dashboard and uses it to adjust the instruction?The project work will include design, development, pilot testing, and classroom studies. The dashboard will be designed with substantial teacher input. Further, the project will provide teacher guides for how to use the dashboard via the Mathtutor website. The dashboard will work with all Mathtutor units and all tutors built with CTAT/Tutorshop, a widely used tutor-building infrastructure. Diverse student groups will benefit, as tutoring software has been effective with a wide range of students, including minority students, non-native English speakers, and low-income students.

改善K-12科学，技术，工程和数学（STEM）的学习是一个关键的国家需求，因为越来越多的工作需要STEM熟练。最近，智能辅导系统（ITS）在改善初中和高中的STEM学习方面表现出了巨大的潜力。虽然这些导师直接支持学生，但他们不向教师提供信息。该项目将通过开发软件来弥补这一缺陷，该软件将显示学生在中学数学方面的进步，并将建议教师可以向学生提供帮助，以提高他们的学习。该软件提供的帮助是基于导师内置的学习分析，但过于复杂，教师无法使用。本项目将采用以用户为中心的设计方法，为ITS创建教师仪表板，以便在各种现实的课堂场景中发挥作用。将进行课堂研究，以评估教师使用仪表板时，仪表板是否有助于学生更有效地学习。这项工作将集中在Mathtutor上，这是一个免费提供的网站，为中学数学学习提供智能辅导软件。具体来说，该项目将侧重于Lynnette，7年级和8年级的导师，在帮助学生学习求解线性方程方面有着良好的记录。需要解决的研究问题包括：智能辅导系统可以提供的关于学生学习的最新数据对教师有帮助，以及如何以可操作的方式最好地呈现这些数据？教师如何使用仪表板中呈现的可操作分析来帮助学生？当老师监控仪表板并使用它来调整教学时，学生是否学得更好？项目工作将包括设计、开发、试点测试和课堂研究。仪表板的设计将与大量的教师投入。此外，该项目将通过Mathtutor网站为教师提供如何使用仪表板的指南。仪表板将与所有Mathtutor单元和所有使用CTAT/Tutorshop构建的导师一起工作，CTAT/Tutorshop是一种广泛使用的导师构建基础设施。不同的学生群体将受益，因为辅导软件对各种各样的学生都很有效，包括少数民族学生，非英语母语学生和低收入学生。
