The ability to express scientific concepts in mathematical terms and integrate scientific and mathematical reasoning about a phenomenon is a foundational cognitive process involved in scientific thinking. This process called "blended math-science sensemaking" (MSS) is a desired skill for all science, technology, engineering, and math…

Digital simulations are powerful instructional tools for physics education. They are often designed to visualize canonical physical phenomena, with adjustable parameters for influencing the system. While this is sufficient for developing conceptual and qualitative intuitions, it does little to help physics students build connections between…

When thinking about measurement uncertainty in a laboratory experiment that features quantum mechanical effects, it is important to consider both the physical principles of underlying quantum theory (e.g., the uncertainty due to quantum mechanical superposition states) as well as the limitations of the measurement (e.g., the spread in outcomes due…

Physics graduate teaching assistants (GTAs) are tasked with multifaceted teaching assignments, such as leading tutorials and inquiry-based laboratories, yet their professional development rarely includes opportunities to rehearse complex pedagogical skills or receive feedback on their teaching. In this study, physics GTAs practiced specific…

We report on a study of the effects of laboratory activities that model fictitious laws of physics in a virtual reality environment on (i) students' epistemology about the role of experimental physics in class and in the world; (ii) students' self-efficacy; and (iii) the quality of student engagement with the lab activities. We create…

Following the global COVID-19 pandemic, digital learning environments have gained in importance in education all around the world. A new digital learning format called a "Digital Learning Module" (DLM) was developed within the Physics Education Research (PER) group at CERN, consisting of a series of prerecorded explanatory and experiment…

Laboratory courses are an important part of the undergraduate physics curriculum. During physics labs, students can engage in authentic, hands-on experimental practices, which can prepare them for graduate school, research laboratories, and jobs in industry. Because of the COVID-19 pandemic in Spring 2020, colleges and universities across the…

Physics lab instructors were forced to adapt their courses in 2020 due to the COVID-19 pandemic. We investigate the impact these changes had on student views towards experimental physics as measured by the Colorado Learning Attitudes about Science Survey for Experimental Physics (E-CLASS). Analysis of the responses from over 1600 students in both…

This paper describes a comprehensive review of 31 quasi or experimental research studies from the past decade on the effect of PhET simulations on students' conceptual understanding of physics. Two questions guided the review: (i) To what extent do PhET simulations enhance students' conceptual understanding of physics? (ii) What are the best ways…

In this study, we evaluate the impact of rehearsing teaching skills in a mixed-reality classroom simulator on graduate teaching assistants' (GTAs) instructional practices as well as undergraduate student learning outcomes. The simulator training is intended to provide GTAs opportunities to deliberately practice essential pedagogical skills that…

This study aims to examine the effectiveness of metacognitive scaffolding in different inquiry tasks related to optics. Two high school classes participated in this study. One class, the treatment group (n = 33), which integrated metacognitive prompts into the simulation-based inquiry, was compared to the other class, the control group (n = 34),…
