Integrating computing and mathematics appeals to various stakeholders for a variety of reasons. For the mathematics education community, computing offers an application of mathematics concepts that may strengthen teachers' and students' mathematical understanding; for the computer science (CS) education community, integration enables equitable access to computing education for all students; for state boards and districts, integration accommodates staffing and curricular constraints while targeting core learning objectives in multiple disciplines. Bootstrap is a nationally-deployed curriculum that integrates computer science and algebra. Bootstrap's current professional development (PD) program for math teachers is a 3-day in-person event which assumes that teachers are somewhat facile with algebraic functions. Both Bootstrap and the National Council for Teachers of Mathematics (NCTM) have observed that some teachers have a weak command of functions. School districts would prefer a shorter in-person PD to reduce staffing costs and increase flexibility. This project will use a hybrid PD model to address both needs. Simultaneously, the project will research ways to tailor the online content to be effective for teachers who differ in their understanding of functions, goals for pursuing PD, and interest in mathematics, computing, math/CS integration, and student thinking. This Researcher-Practitioner Partnership team includes Bootstrap; NCTM (specifically its Math Forum team, which has expertise in on-line training); Brown University; Swarthmore College; the Oklahoma State Division of Secondary Mathematics and Computing Education and school districts in Texas. A total of 270 middle-school math teachers---a majority from rural areas or serving Native American or Hispanic students in our partnering regions---will participate in Bootstrap PD under this project. Assuming typical adoption rates, these teachers should reach 6,000 students within the project period alone. Building Bootstrap content into the Math Forum will expose thousands of NCTM's teachers to the potential of integrated math/CS curricula. The team will use design-based research to develop and deploy a hybrid PD model and online support community for Bootstrap teachers, augment Bootstrap PD to reinforce teachers' understanding of algebraic functions, and conduct quasi-experimental studies to inform the design of different pathways through the PD. This project will study how to develop teachers' understanding of CS while also strengthening their math proficiency. In particular, the project will explore the possibilities for CS to improve teachers' understanding of algebraic functions. The project also will study ways in which teachers' interest can be made visible and useful in improving engagement and learning in integrated CS and mathematics PD. The results should apply to integrative programs beyond Bootstrap, suggesting strategies to tailor PD to serve more teachers.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.

由于各种原因，集成计算和数学吸引了各种利益相关者。对于数学教育界来说，计算提供了数学概念的应用，可以加强教师和学生的数学理解；对于计算机科学（CS）教育界来说，整合使所有学生都能公平地接受计算机教育；对于州委员会和地区来说，整合在针对多学科的核心学习目标的同时，适应了人员配备和课程限制。Bootstrap是一门整合了计算机科学和代数的全国性课程。Bootstrap目前针对数学教师的专业发展（PD）项目是一个为期3天的面对面活动，该项目假设教师对代数函数比较熟悉。Bootstrap和全国数学教师委员会（NCTM）都注意到一些教师对函数的掌握很弱。学区更喜欢更短的面对面PD，以减少人员成本并增加灵活性。该项目将使用混合PD模型来满足这两种需求。同时，该项目将研究如何定制在线内容，使其对不同的教师有效，这些教师对功能的理解不同，追求PD的目标不同，对数学，计算，数学/CS集成和学生思维的兴趣不同。这个研究从业者合作团队包括Bootstrap；NCTM（特别是它的数学论坛团队，他们有在线培训的专业知识）；布朗大学;斯沃斯莫尔学院;俄克拉何马州中学数学和计算机教育部门以及德克萨斯州的学区。共有270名中学数学教师将参加这个项目下的Bootstrap PD，其中大多数来自农村地区，或者在我们的合作地区为美洲原住民或西班牙裔学生服务。假设典型的采用率，这些教师仅在项目期间就应该达到6000名学生。将Bootstrap的内容纳入数学论坛将使NCTM的数千名教师接触到综合数学/计算机科学课程的潜力。该团队将使用基于设计的研究，为Bootstrap教师开发和部署混合PD模型和在线支持社区，增强Bootstrap PD以加强教师对代数函数的理解，并进行准实验研究，为通过PD的不同路径的设计提供信息。这个项目将研究如何发展教师对CS的理解，同时加强他们的数学能力。特别是，该项目将探索CS提高教师对代数函数理解的可能性。该项目还将研究如何使教师的兴趣在提高CS和数学综合PD的参与度和学习中显现出来并发挥作用。结果应该适用于Bootstrap之外的综合项目，为定制PD以服务更多教师提出策略。该奖项反映了美国国家科学基金会的法定使命，并通过使用基金会的知识价值和更广泛的影响审查标准进行评估，被认为值得支持。
