Student understanding of the nature of science and scientific measurement are critical for any science curriculum. In physics, students experience the ideas of measurement in two very different contexts: classical measurement and quantum mechanical measurement. This project will develop a better understanding of the ways students think about measurement in each context. It will also help us understand relations between the two. Do students carry lines of thinking about classical measurement into their quantum mechanics courses? When students learn about quantum mechanical measurements, do their lines of thinking about classical measurement change in response? This project will test how well we can generalize existing research on student understanding of measurement. This will be done by extending the research to new institutions, at different instructional levels, and in quantum mechanical contexts. This study will lay the groundwork for improving instruction related to measurement at all levels. This project will address two research questions. First, it will ask how students reason about measurement across the university physics curriculum, classically and quantum mechanically. Secondly it will ask what the interplay is between how students reason about measurement in classical and quantum contexts. Student understanding of classical measurement has been characterized by a point reasoning and set reasoning paradigms. In point reasoning, each measurement could be the true value. In set reasoning, each measurement is an estimate of the true value. Situational interviews will cue either classical or quantum reasoning about measurement. Some cues will come from referring to activities in introductory labs or quantum mechanics courses. Other cues will come from the physical environment of the interviews. Interview results will then be analyzed to identify the relationships between reasoning about measurement in either context. Results from the interviews will inform the development of surveys that can be distributed more broadly to evaluate reasoning of a wider range of students at the two institutions and beyond.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.

学生对科学本质和科学测量的理解对于任何科学课程都至关重要。在物理学中，学生在两种截然不同的背景下体验测量的想法：经典测量和量子力学测量。该项目将更好地理解学生在每种情况下思考测量的方式。这也将有助于我们了解两者之间的关系。学生是否将经典测量的思路带入量子力学课程中？当学生学习量子力学测量时，他们对经典测量的思维方式是否会随之改变？ 该项目将测试我们能否很好地推广现有的关于学生对测量的理解的研究。这将通过将研究扩展到不同教学水平和量子力学背景的新机构来完成。 这项研究将为改进各级测量相关教学奠定基础。 该项目将解决两个研究问题。首先，它将询问学生如何在大学物理课程中，从经典力学和量子力学角度推理测量。其次，它将询问学生如何在经典和量子背景下推理测量之间的相互作用。 学生对经典测量的理解具有点推理和集合推理范式的特点。在点推理中，每次测量都可能是真实值。在集合推理中，每次测量都是对真实值的估计。情景访谈将提示有关测量的经典推理或量子推理。一些线索将来自介绍性实验室或量子力学课程中的活动。其他线索将来自采访的物理环境。然后对访谈结果进行分析，以确定在任一情况下测量推理之间的关系。访谈结果将为调查的开展提供信息，这些调查可以更广泛地分发，以评估这两个机构及其他机构更广泛学生的推理。该奖项反映了 NSF 的法定使命，并通过使用基金会的智力价值和更广泛的影响审查标准进行评估，被认为值得支持。
