The Robot Algebra Project creates three scalable, middle school level units for use in informal settings. The units are designed around fundamental robot movement concepts but emphasize proportional reasoning - a big idea in mathematics. There are over 12,000 FIRST Lego League teams across the U.S. that purport to use robots as a motivator to engage students in STEM. However, most of the time the students use guess and check procedures thwarting the opportunity to learn STEM content. The units being developed build upon model eliciting activities, project-based learning and mathematics education to specifically improve student understanding of a few key mathematics concepts. The programming of robots is scaffolded so that students concentrate on the mathematics. Rather than only doing hands-on activities, the students also produce toolkits for other students to engage in similar experiments. Paper- based word problems are developed to bridge the mathematics learned in the context of robotics to generalized mathematical problem-solving strategies. Professional development is provided both face-to-face and through webinars to early adopters who are also trained to provide professional development to others. Materials to supplement the professional development are produced to support teachers and informal educators understanding of the rationale, the agenda, the mathematics and the perspectives that underlie the student materials as well as to also support them in anticipating student responses to the tasks. The materials can be updated online. Pre and post tests against a control group in standard robotics programs are used to provide formative and summative evaluation. Ten students are interviewed each year about how the experiences affect their career choice. The scalability of the use of the units is measured through observation of and interviews with teachers. In the third year the units will be used in beta sites.The fundamental goal of the current proposal is to improve middle school level students? algebraic reasoning ability, specifically their understanding of proportionality. A secondary but critically related goal is to improve informal educators? pedagogical content knowledge with respect to algebraic reasoning ability.

机器人代数项目创建了三个可扩展的中学级单元，以用于非正式设置。 这些单元是围绕基本机器人运动概念而设计的，但强调比例推理 - 数学中的一个重要想法。 美国各地有12,000多个乐高联盟球队，他们旨在使用机器人作为吸引学生参与STEM的动力。 但是，大多数时候，学生使用猜测和检查程序挫败了学习STEM内容的机会。 开发的单位以模型启发活动，基于项目的学习和数学教育为基础，以特别提高学生对一些关键数学概念的理解。 机器人的编程是脚手架的，因此学生专注于数学。 学生们不仅要进行动手活动，还为其他学生提供工具包，以进行类似的实验。 基于纸质的单词问题是为了弥合机器人技术中学到的数学，以介绍通用数学问题解决策略。 面对面和通过网络研讨会向早期采用者提供了专业发展，他们也接受了培训，可以为他人提供专业发展。 生产了补充专业发展的材料，以支持教师和非正式教育者对理由，议程，数学和观点的理解，这些观点是学生材料的基础，并支持他们预期学生对任务的回应。 这些材料可以在线更新。 针对标准机器人计划中的对照组的测试和后测试用于提供形成性和总结性评估。 每年都有关于经验如何影响他们职业选择的十名学生。 使用单元的使用的可伸缩性是通过观察和对教师的访谈来衡量的。 在第三年，该单元将用于Beta站点。当前建议的基本目标是改善中学学生？代数推理能力，特别是他们对相称性的理解。 次要但至关重要的目标是改善非正式教育者？关于代数推理能力的教学内容知识。
