Collaborative Research: Supporting Pre-Service Teachers Mathematical Discourse through Co-Design of Teaching Simulation Tools

该项目旨在通过开发、实施和评估将改进基于证据的数学教学实践的模拟来服务于国家利益。该项目将创建一套开源的、免费提供的模拟，以支持教师在课堂上培养丰富的数学话语。在这样做的同时，它将促进如何为教师学习设计模拟工具的知识，并将阐明为教师准备计划创造技术的设计原则。该项目还将创建数学对话和专业发展材料的开放数据集，以便其他教师教育工作者可以开发自己的定制场景。该项目利用基于网络的基于人工智能的课堂教学模拟(ACTS)核心系统，使教师候选人能够在与动态数学可视化交互的同时排练参与特定数学任务的学生，然后提供关于教师表现的自动定制反馈。模拟将与数学方法讲师共同设计，并在任职前的小学数学方法课程中实施。其目的是向职前教师候选人提供关于他们提出的数学问题类型的自动反馈，并评估对职前教师候选人在模拟环境中使用产出性数学问题的影响。NSF IUSE：EDU计划支持研究和开发项目，以提高所有学生的STEM教育的有效性。通过参与式学生学习路径，该计划支持创建、探索和实施有前途的实践和工具。罗伯特·诺伊斯教师奖学金计划为该项目提供了资金。这一奖项反映了NSF的法定使命，并通过使用基金会的智力优势和更广泛的影响审查标准进行评估，被认为值得支持。

This project aims to serve the national interest by developing, implementing, and evaluating simulations that will improve evidence-based mathematics teaching practices. The project will create a suite of open-source, freely available simulations that support teachers to foster rich mathematical discourse in their classrooms. While doing so, it will advance knowledge of how to design simulation tools for teacher learning and will articulate design principles for creating technologies for teacher preparation programs. The project will also create open data sets of the mathematical dialogue and professional development materials so that other teacher educators can develop their own customized scenarios.The project leverages the web-based AI-based Classroom Teaching Simulation (ACTS) Core system that enables teacher candidates to rehearse engaging with a student about a specific mathematical task while interacting with a dynamic mathematical visualization and then provides automated tailored feedback on teacher performance. Simulations will be co-designed with mathematics methods instructors and implemented within pre-service elementary mathematics methods courses. The goal is to provide automated feedback to pre-service teacher candidates on the types of mathematical questions they ask and evaluate the impact on pre-service teacher candidates’ use of productive mathematical questioning during simulation settings. The NSF IUSE: EDU Program supports research and development projects to improve the effectiveness of STEM education for all students. Through the Engaged Student Learning track, the program supports the creation, exploration, and implementation of promising practices and tools. The Robert Noyce Teacher Scholarship program contributed to the funding of this project.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.
