Stump, Emily M.; Dew, Matthew; Jeon, Sophia; Holmes, N. G. – Physical Review Physics Education Research, 2023
Prior research has indicated that students in the undergraduate physics lab divide work inequitably with regard to gender. In this work, we further probed women's experiences in lab group work, focusing on women who take on managerial and leadership roles in the lab. We interviewed and surveyed women enrolled in a sophomore-level project-based lab…

Schang, Andy; Dew, Matthew; Stump, Emily M.; Holmes, N. G.; Passante, Gina – Physical Review Physics Education Research, 2023
Uncertainty is an important and fundamental concept in physics education. Students are often first exposed to uncertainty in introductory labs, expand their knowledge across lab courses, and then are introduced to quantum mechanical uncertainty in upper-division courses. This study is part of a larger project evaluating student thinking about…

Wu, David G.; Heim, Ashley B.; Sundstrom, Meagan; Walsh, Cole; Holmes, N. G. – Physical Review Physics Education Research, 2022
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…

Walsh, Cole; Lewandowski, H. J.; Holmes, N. G. – Physical Review Physics Education Research, 2022
Instructional labs are fundamental to an undergraduate physics curriculum, but their possible learning goals are vast with limited evidence to support any particular goal. In this study, we evaluate the efficacy of labs with different goals and structures on students' critical thinking skills and views about experimentation, using an extensive…

Sundstrom, Meagan; Wu, David G.; Walsh, Cole; Heim, Ashley B.; Holmes, N. G. – Physical Review Physics Education Research, 2022
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…

Holmes, N. G.; Heath, Grace; Hubenig, Katelynn; Jeon, Sophia; Kalender, Z. Yasemin; Stump, Emily; Sayre, Eleanor C. – Physical Review Physics Education Research, 2022
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…

Sundstrom, Meagan; Schang, Andy; Heim, Ashley B.; Holmes, N. G. – Physical Review Physics Education Research, 2022
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…

Sundstrom, Meagan; Heim, Ashley B.; Park, Barum; Holmes, N. G. – Physical Review Physics Education Research, 2022
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,…

Phillips, Anna McLean; Sundstrom, Meagan; Wu, David G.; Holmes, N. G. – Physical Review Physics Education Research, 2021
With the adoption of instructional laboratories that require students to make their own decisions, there is a need to better understand students' activities as they make sense of their data and decide how to proceed. In particular, understanding when students do not engage productively with unexpected data may provide insights into how to better…

Walsh, Cole; Stein, Martin M.; Tapping, Ryan; Smith, Emily M.; Holmes, N. G. – Physical Review Physics Education Research, 2021
Omitted variable bias occurs in most statistical models. Whenever a confounding variable that is correlated with both dependent and independent variables is omitted from a statistical model, estimated effects of included variables are likely to be biased due to omitted variables. This issue is particularly problematic in physics education research…

Kalender, Z. Yasemin; Stump, Emily; Hubenig, Katelynn; Holmes, N. G. – Physical Review Physics Education Research, 2021
Instructional physics labs offer students unique opportunities to develop an understanding of experimentation. By transforming labs to be more open ended and experimentation focused, instructors can better support student agency and choice. In this study, we examine students' overall sense of and perceptions about agency in two…

Smith, Emily M.; Holmes, N. G. – Physical Review Physics Education Research, 2020
The goals for lab instruction are receiving critical attention in the physics education community due to multiple reports and research findings. In this paper, we describe a theoretically motivated scheme to evaluate instructional lab curricula and apply that scheme to three implementations of an electricity and magnetism lab curriculum. The…

Holmes, N. G.; Lewandowski, H. J. – Physical Review Physics Education Research, 2020
Physics lab instruction is evolving in response to changing technology, a desire to better prepare students for diverse careers, and renewed focus from physics education researchers. To prepare researchers to evaluate progress in instructional labs in the future, this study set out to understand the current state of instructional physics labs in…

Burkholder, Eric; Walsh, Cole; Holmes, N. G. – Physical Review Physics Education Research, 2020
Physics education research (PER) has long used concept inventories to investigate student learning over time and to compare performance across various student subpopulations. PER has traditionally used normalized gain to explore these questions but has begun to use established methods from other fields, including Cohen's "d," multiple…

Quinn, Katherine N.; Kelley, Michelle M.; McGill, Kathryn L.; Smith, Emily M.; Whipps, Zachary; Holmes, N. G. – Physical Review Physics Education Research, 2020
Instructional labs are being transformed to better reflect authentic scientific practice, often by removing aspects of pedagogical structure to support student agency and decision making. We explored how these changes impact men's and women's participation in group work associated with labs through clustering methods on the quantified behavior of…
