Collaborative Research: Broadening Use of Modern Geodetic Methods in Earth Science Field Courses

该项目旨在通过提高学生在地球科学领域课程中获得尖端大地测量学方法的机会，为高质量的STEM本科教育服务。大地测量学是一门精确测量和理解地球几何形状、空间方向和重力场以及这些特性如何随时间变化的科学。大地测量技术可以应用于社会关键的地球科学主题，如危害评估和响应，以及具有商业或政府价值的主题。因此，大地测量技术正在推动劳动力需求的变化，并增加了在本科教育中包括大地测量场方法和相关定量技能的需求。为了满足这些需求，该项目计划：培训教师如何将大地测量场方法纳入其大学课程；制定贷款计划，为教育工作者提供使用大地测量设备的机会；增加对教员的技术支持。该项目旨在拓宽本科生接触GPS、运动结构（SfM）和地面激光扫描（TLS）大地测量技术的途径。为了提高学生对大地测量学的参与度和学习，该项目将为教师开设短期课程。这些短期课程将帮助教师确定与社会相关的地球科学研究问题，这些问题将为学生学习和应用大地测量技术提供相关性和背景。100多名教师将参加这些短期课程，1500多名学生将在资助期间学习使用大地测量场方法。该项目旨在促进大学教学的可持续变化，从而在未来惠及更多的学生。该项目将审查通过1天和2.5天短期课程以及通过更密集、更小的队列小组制作的教材的效果和采用情况。这些数据将有助于教育研究，特别是关于教师专业发展对改善实地教育的影响的研究。项目参与者编写的教材将继续通过科学教育资源中心的网站（serc.carleton.edu/getsi）进行评估和传播，该网站每年有500万访问者。该项目响应了社区的需求，并有可能为多样化的、为地球科学做好准备的STEM劳动力的关键需求做出贡献。该项目由美国国家科学基金会IUSE: EHR项目支持，该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。该项目处于参与式学生学习跟踪和发展与实施层；它建立在早期iuse资助的探索和设计层项目的基础上。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 in high-quality undergraduate STEM education by improving student access to cutting-edge geodesy methods in Earth Science field courses. Geodesy is the science of accurately measuring and understanding the Earth's geometric shape, orientation in space, and gravity field, and how these properties change over time. Geodetic technologies can be applied to societally critical geoscience topics such as hazard assessment and response, as well as to topics with commercial or governmental value. As a result, geodetic technologies are driving changes in workforce demands and increasing the need for including geodetic field methods and related quantitative skills in undergraduate education. To meet these needs, the project plans to: train instructors how to incorporate geodetic field methods into their college courses; develop a loan program to provide educators access to geodetic equipment; and increase the availability of technical support for instructors.This project specifically aims to broaden access of undergraduate students to the geodetic technologies of GPS, Structure from Motion (SfM), and Terrestrial Laser Scanning (TLS). To increase student engagement and learning in geodetics, the project will create short courses for instructors. These short courses will help instructors identify societally-relevant geoscience research questions that will provide relevance and context for students to learn and apply geodetic technologies. More than 100 instructors will participate in these short courses, resulting in more than 1500 students who will learn to use geodetic field methods over the course of the grant. The project aims to develop sustainable changes in college instruction that could reach even more students in the future. The project will examine the efficacy and adoption of teaching materials produced through 1-day and 2.5-day short courses, as well as through more intensive, smaller cohort groups. These data will contribute to the body of educational research, particularly research on the impact of faculty professional development in improving field education. The teaching materials developed by the project participants will continue to be evaluated by and disseminated through the website of the Science Education Resource Center (SERC), which has 5 million visitors per year (serc.carleton.edu/getsi). This project responds to community needs and has the potential to contribute to the critical need for a diverse, Earth Science-ready STEM workforce. This project is supported by the NSF IUSE: EHR Program, which supports research and development projects to improve the effectiveness of STEM education for all students. This project is in the Engaged Student Learning track and Development and Implementation tier; it builds on work of an earlier IUSE-funded Exploration and Design tier project. Through the Engaged Student Learning track, the program supports the creation, exploration, and implementation of promising practices and tools.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.
