As physics laboratory courses (labs) transition from traditional, model-verifying activities to discovery-based investigations, it becomes crucial to understand the role of the instructor in the implementation of various lab types. Prior work has started to address this need by examining either coarse-grained frequencies or fine-grained content of…

Physics education research is replete with observations and proposed explanations for gender disparities in physics. In this work, we operationalize a definition for equity as everyone has access to the learning environment and everyone's voice is heard (adapted from previous definitions). We review prior research that observed inequities in…

The human brain is a byproduct of the natural process of evolution, as is the knowledge it contains. Like other natural resources fit for human consumption, knowledge can be modeled as a physical entity that can be sought after and acquired. In ancient times, knowledge was geographically constrained as a consequence of being a physical entity…

Recent advancements in large language models (LLMs) hold significant promise for improving physics education research that uses machine learning. In this study, we compare the application of various models for conducting a large-scale analysis of written text grounded in a physics education research classification problem: identifying skills in…

Engaging in interactions with peers is important for student learning. Many studies have quantified patterns of student interactions in in-person physics courses using social network analysis, finding different network structures between instructional contexts (lecture and laboratory) and styles (active and traditional). Such studies also find…

Previous work has identified that recognition from others is an important predictor of students' participation, persistence, and career intentions in physics. However, research has also found a gender bias in peer recognition in which student nominations of strong peers in their physics course disproportionately favor men over women. In this…

Researchers have pinpointed recognition from others as one of the most important dimensions of students' science and engineering identity. Studies, however, have found gender biases in students' recognition of their peers, with inconsistent patterns across introductory science and engineering courses. Toward finding the source of this variation,…

Preprint articles are available on servers, such as arXiv and ChemRxiv, at no-cost to benefit the movement toward open access of research. However, the use of preprint research articles as a reference source in academia is not heavily documented. To examine if researchers are utilizing preprint articles, this paper examines citation trends in the…

Improving student success rates in introductory calculus and physics courses is critically important for our students' path in STEM fields. Many of the students who have an intuitive understanding of physics fail calculus and are pushed to delay or drop their majors in technical fields. One way of addressing this issue is by adopting a program…

Understanding social interactions among students comprises a rich area of physics education research. Here we focus on the social interactions in introductory physics laboratories (labs). Most existing research in such contexts focuses on within-group social dynamics, however, we argue that interactions between different lab groups are just as…

Playground Physics is a supplemental middle school science program designed to support embodied learning by enabling students to connect physics concepts to their own playful activities. The purpose of this study was to examine a model for scaling up the Playground Physics program and to determine the program's impact on middle school students'…

In a small physics department it can be difficult to develop and maintain an environment that engages students of all levels, and encourages and facilitates student growth in curricular and co-curricular experiences. This difficulty can be amplified when the number of physics majors is small, especially with fewer than 15-20 majors in the program.…

Given the insufficient number of well-qualified future physics teachers in the U.S., physics programs often seek guidance for how to address this national need. Measurement tools can provide such guidance, by both defining excellence in physics teacher education (PTE) and providing a means to measure progress towards excellence. This paper…

Cross-connections between the sciences and mathematics are emphasized through the Next Generation Science Standards and the Common Core State Standards in the United States. One topic that is a common bridge between math and science is the concept of measurement and unit conversions in the metric/English system. This article uses a mixed-methods…

This research is comprised of a three-part examination of equity, access, achievement, and learning in precollege physics. The first study examined teacher-level and school-level predictors of student performance in physics, with a focus on isolated teachers in New York during the 2016-17 academic year. Results indicated 40% of physics teachers…
