Collaborative Research: An impact study to examine the efficacy of a mathematics professional development program for elementary teachers

该项目将开发和研究扩展模型对小学二年级和三年级教师的数学专业发展（PD）的影响。它建立在美国国家科学基金会资助的项目，所有包括在数学（AIM）。PD是专为小学教师学习和使用成功的数学讨论策略，以支持学生的学习。该项目将扩展该框架，通过基于网络的工具改善教师对资源的获取，瞄准PD教师的新目标受众，并通过分析学生数据来研究AIM项目的影响。大学教师和学区数学课程负责人之间的项目伙伴关系将开发基于网络的专业发展资源。该项目由三个项目共同资助：ITEST、EHR核心研究和网络学习。EHR核心研究项目强调在该领域产生基础知识的基础STEM教育研究。投资在至关重要、广泛和持久的关键领域：STEM学习和STEM学习环境，扩大STEM参与，以及STEM劳动力发展。该项目还将推进“面向学生和教师的创新技术体验”（ITEST）项目的工作，以更好地理解和促进提高学生在科学、技术、工程或数学（STEM）领域追求职业的动机和能力的实践。网络学习和未来学习技术计划资助的工作将有助于设想下一代学习技术，并推进我们对人们如何在技术丰富的环境中学习的了解。该项目的总体目标是开展一项有效性研究，以了解针对小学数学教师的专业发展计划如何在基于网络的促进者支持和原始研发团队的支持较少的情况下使用。研究问题是关于没有参与先前项目的教师在多大程度上可以忠实地实施新的AIM项目材料。本研究亦将探讨专业发展对教师的知识、信念及数学教学的影响。最后，该研究还考察了对学生参与数学讨论和内容学习的影响，特别关注英语学习者。这项研究是一项实验性设计，其中学校团队被随机分配到初始治疗或延迟治疗的条件下。将收集数据以了解干预的有效性，包括促进者实施日志、教师知识测量、课堂文物、课堂观察、学生话语观察和学生成绩数据。

The project will develop and research the impact of an expanded model for mathematics professional development (PD) for elementary second and third grade teachers. It builds on the NSF-funded project, All Included in Mathematics (AIM). The PD is designed for elementary teachers to learn and use successful mathematics discussion strategies shown to support student learning. This project will expand the framework by improving teacher access to resources with web-based tools, targeting a new target audience of teachers in PD, and researching the impact of Project AIM via analysis of student data. The project partnership between university faculty and mathematics curriculum leaders from school districts will develop the web-based professional development resources. The project is co-funded by three programs: ITEST, EHR Core Research and Cyberlearning. The EHR Core Research program emphasizes fundamental STEM education research that generates foundational knowledge in the field. Investments are made in critical areas that are essential, broad and enduring: STEM learning and STEM learning environments, broadening participation in STEM, and STEM workforce development. This project will also advance efforts of the Innovative Technology Experiences for Students and Teachers (ITEST) program to better understand and promote practices that increase students' motivations and capacities to pursue careers in fields of science, technology, engineering, or mathematics (STEM). The Cyberlearning and Future Learning Technologies Program funds efforts that will help envision the next generation of learning technologies and advance what we know about how people learn in technology-rich environments.The overarching goal of the project is to conduct an efficacy study to understand how a professional development program, targeting elementary math teachers, can be used with web-based facilitator support and less support from the original research and development team. The research questions ask about the extent to which teachers who did not work with the prior project can implement the new Project AIM materials with fidelity. The research will also investigate the impact of the professional development on teachers' knowledge, beliefs and mathematics teaching. Finally, the study is also examining the impact on students' participation in mathematics discussions and content learning with particular attention to English Language Learner students. The study is an experimental design in which school teams are randomly assigned to the initial treatment or delayed treatment conditions. Data will be collected to understand the efficacy of the intervention and will include facilitator implementation logs, measures of teacher knowledge, classroom artifacts, classroom observations, student discourse observation and student achievement data.
