Using Visual Computing to Deepen Mathematical Learning in Preservice K-8 Teacher Education

该项目旨在通过利用视觉计算技术和工程设计过程的进步，改善职前K-8教师的数学教育课程，为国家利益服务。K-8教师需要让未来的学生为需要工程、人工智能（AI）、数学和推理技能的职业做好准备。该项目属于IUSE: EDU参与学生学习的2级轨道，通过在亚利桑那州立大学高年级数学方法课程的课程、活动和评估中整合视觉计算和工程设计过程，显著提高职前教师的跨学科数学技能。通过将这些学科纳入数学课堂，该项目将使职前教师和他们未来的学生参与抽象数学概念的应用学习，并展示这些知识在现实世界中的跨学科应用。研究将研究建议的干预措施在支持K-8课堂数学情境化方面的有效性。该项目将通过科学出版物和会议演讲广泛传播新课程，并建立一个在线平台，与公众分享视频、教案和活动以及教师资源。这个项目的重点是产生和推进关于使用工程设计过程和视觉计算的知识来将数学语境化。这些目标将通过10周的课程整合到亚利桑那州立大学的高级数学教师教育（MTE） 311课程中，名为“K-8教学的几何，代数，统计和概率”，该课程每年将为大约180名职前教师提供服务。项目团队将通过一种新颖的混合方法研究设计来调查职前教师的敬业度、动机、态度和自我效能感。研究结果将有助于进一步了解教师面临的挑战和解决方案，这些挑战和解决方案涉及到教师准备计划中的可视化计算。开发的课程将由该项目的职前教师教授给K-8年级的学生，作为他们在亚利桑那州大凤凰城学校实习的一部分。课程和研究成果的公开传播将通过演讲、出版物、研讨会和在线资源中心的开发，成为改善跨学科数学教育的全国模式。NSF IUSE: EDU项目支持研究和开发项目，以提高所有学生STEM教育的有效性。通过参与学生学习轨道，该计划支持有前途的实践和工具的创建，探索和实施。该项目的部分资金来自Robert Noyce教师奖学金计划。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。

This project aims to serve the national interest by improving curricula in mathematics education for preservice K-8 teachers leveraging advances in visual computing technology and the engineering design process. K-8 teachers need to prepare future students for careers that require engineering, artificial intelligence (AI), mathematics and reasoning skills. This project falls under the IUSE: EDU Level 2 track in Engaged Student Learning by significantly advancing preservice teachers’ interdisciplinary mathematics skills by integrating visual computing and the engineering design process in lessons, activities, and assessments for an upper division mathematics methods course at Arizona State University. By incorporating these disciplines into the mathematics classroom, the project will engage both preservice teachers and their future students in applied learning of abstract mathematics concepts and demonstrate the real-world interdisciplinary applications of such knowledge. Research will study the effectiveness of the proposed intervention in supporting the contextualization of mathematics in the K-8 classroom. The project will feature broad dissemination of new curriculum through scientific publications and conference presentations as well as an online platform for sharing videos, lesson plans and activities, and teacher resources with the public. This project focuses on generating and advancing knowledge regarding the use of both the engineering design process and visual computing to contextualize mathematics. These goals will be accomplished through 10-week curricular integration into Arizona State University’s upper-division Mathematics Teacher Education (MTE) 311 course entitled “Geometry, Algebra, Statistics, and Probability for K-8 Teaching”, a course which will serve approximately 180 preservice teachers per year. The project team will investigate preservice teachers’ engagement, motivation, attitudes, and self-efficacy through a novel mixed-methods study design. Research findings will help advance understanding of instructor challenges and solutions regarding the integration of visual computing in teacher preparation programs. The developed curriculum will be taught to students in grades K-8 by preservice teachers in the program as part of their placements in schools in greater Phoenix, Arizona. Public dissemination of both the curriculum and the research findings will serve as a national model for improved interdisciplinary mathematics education through presentations, publications, workshops, and development of an online resource hub. 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.Partial funding for the project is from the Robert Noyce Teacher Scholarship program.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.
