This project aims to serve the national interest by creating curricula for undergraduate students who are future middle and high school mathematics teachers. These materials will be used to prepare future teachers to learn how to use technology to lead productive mathematics discussions when teaching geometry concepts. The Level 3 Engaged Student Learning project has three goals: 1) create online modules focused on preparing future teachers to facilitate productive mathematics discussions with the use of web-based dynamic geometry tools, 2) conduct research studies on future middle and high school mathematics teachers’ noticing of grades 6-12 students’ geometric thinking while using technology and the ways they use that analysis to plan a productive discussion, and 3) provide support for mathematics teacher educators to use the materials with prospective teachers at their institutions.The curriculum materials will include tasks that are of high cognitive demand, including video cases and samples of middle and high school students’ work on those tasks to prepare future middle and high school mathematics teachers to analyze students’ thinking and use that thinking to lead productive discussions. The project team will conduct research on 40-60 future teachers’ by examining how they analyze students’ thinking with technology and the ways they use that analysis to plan to lead discussions. Research will also be conducted on 30-40 mathematics teacher educators to study the impacts of the support on their knowledge of technology, pedagogy, and technology. Findings will be disseminated broadly through conference presentations and research publications. The curriculum materials that are developed by the project will be freely distributed to mathematics teacher educators across the nation using an existing online professional learning portal. The NSF IUSE: EDU Program supports research and development projects to improve the effectiveness of STEM education for all students for Engaged Student Learning projects. Through the Engaged Student Learning track, the program supports the creation, exploration, and implementation of promising practices and tools.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

该项目旨在通过为未来初中和高中数学教师的本科生创建课程来服务国家利益，这些材料将用于帮助未来教师学习如何在教授几何概念时使用技术来引导富有成效的数学讨论。 3 学生参与学习项目有三个目标：1) 创建在线模块，重点帮助未来教师利用基于网络的动态几何工具促进富有成效的数学讨论，2) 对未来初中和高中数学教师的注意力进行研究6-12年级学生在使用技术时的几何思维以及他们使用该分析来计划富有成效的讨论的方式，以及 3) 为数学教师教育工作者提供支持，以便与所在机构的未来教师一起使用这些材料。课程材料将包括高难度的任务认知需求，包括初高中学生完成这些任务的视频案例和样本，以帮助未来的初高中数学教师分析学生的思维并利用该思维引导富有成效的讨论。项目团队将对 40 个项目进行研究。 -60 未来教师通过检查他们如何分析学生的思维还将对 30-40 名数学教师教育工作者进行研究，以研究支持对他们的技术、教学法和技术知识的影响。研究结果将通过广泛传播。该项目开发的课程材料将通过现有的在线专业学习门户免费分发给全国各地的数学教师教育工作者。 STEM 教育通过参与学生学习项目，该计划支持有前途的实践和工具的创建、探索和实施。该奖项是 NSF 的法定使命，并通过使用基金会的智力价值进行评估，被认为值得支持。以及更广泛的影响审查标准。
