This project aims to serve the national interest by providing a research base for how instruction changes students’ understanding about measurement in physical systems ranging from the motion of a catapult to that of a single atom. In an effort to better prepare students for twenty-first century STEM careers, post-secondary institutions are rushing to incorporate instruction on data science and quantum information. An important aspect of that preparation is for students to develop a robust understanding of the fundamentals of measurement and its associated variability and uncertainty across all systems, from everyday objects in classical physics to the microscopic particles in quantum mechanical systems. This project hopes to advance understanding of how instruction affects student thinking about measurements and their underlying uncertainty. Uncovering the ways in which student learning is connected to instructional practices should allow curriculum developers to design effective instruction that speaks directly to students’ learning needs and better prepares them for futures beyond the classroom. At present, studies provide mixed results regarding the impact of targeting introductory lab instruction and no results regarding the impact of quantum mechanics instruction on student thinking about uncertainty and measurement concepts. The project plans to employ a mixed-methods approach that combines interviews, document analysis, survey analysis, natural language processing, and qualitative and quantitative cluster analyses. The project team will actively recruit a broad and diverse set of student responses from a range of institutions and institution types, such that the results may be more generalizable to students nationwide than is standard in the physics education research literature. The goals of the project are to (a) characterize instruction on the topics of uncertainty and measurement in introductory and upper-level courses, (b) articulate student profiles based on student reasoning about uncertainty and measurement along multiple dimensions, and (c) identify any shifts in student thinking as a result of different instructional strategies. The results should provide intellectual merit that span a disconnected literature from physics lab instruction to quantum mechanics instruction, motivating critical future work to invoke change across an undergraduate physics curriculum. 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.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.

该项目旨在通过提供研究基础来实现国家利益，以指导教学如何改变学生对物理系统测量的理解，从弹射器的运动到单个原子的测量。为了更好地为学生做好二十一世纪STEM职业的准备，专上机构急于纳入有关数据科学和量子信息的指导。该准备工作的一个重要方面是让学生对所有系统的测量基础及其相关的可变性和不确定性发展，从经典物理学的每天对象到量子机械系统中的显微镜粒子。该项目希望提高对教学的理解，从而影响学生对测量及其基本不确定性的思考。揭示学生学习与教学实践的联系方式应允许课程开发人员设计有效的教学，以直接满足学生的学习需求，并更好地为他们为课堂以外的未来做准备。目前，研究对靶向引入实验室指示的影响以及关于量子机械指示对学生思考不确定性和测量概念的影响的影响的结果混杂。该项目计划采用混合方法，将访谈，文档分析，调查分析，自然语言处理以及定性和定量集群分析结合起来。该项目团队将积极从各种机构和机构类型中招募一系列广泛而多样的学生回应，以便比物理教育研究文献中的标准在全国范围内对学生的结果更为普遍。该项目的目标是（a）表征有关不确定性和介绍和高层课程的测量主题的指示，（b）根据学生对不确定性和沿多维的不确定性的推理来阐明学生概况，以及（c）确定学生思维的任何变化，是不同教学策略的结果。结果应提供智力优点，涉及从物理实验室指示到量子力学指令的断开文献，激发了批判的未来工作，以调用本科物理课程的变化。 NSF IUSE：EDU计划支持研发项目，以提高所有学生STEM教育的有效性。通过参与的学生学习轨道，该计划支持了承诺实践和工具的创建，探索和实施。该奖项反映了NSF的法定任务，并使用基金会的知识分子优点和更广泛的影响评估审查标准，被认为是珍贵的支持。
