[This paper is part of the Focused Collection in Investigating and Improving Quantum Education through Research.] The modern physics course is a crucial gateway for physics majors as it provides an introduction to concepts beyond the scope of the K-12 education. This study collected 167 modern physics syllabi from 127 U.S. research-intensive…

Over the past half-century, numerous attempts have been made to derive the centripetal acceleration formula by treating circular motion as a superposition of uniform and accelerated rectilinear motions over short time intervals. Critical examination reveals that these methods are manifestations of the same approach pioneered by Huygens to…

To explain experiences of riders of rotating systems, such as a merry-go-round, some physics educators have employed the concept of 'centrifugal force.' However, others have suggested that the term is unnecessary in explaining experiences in rotating systems and that it encourages misconceptions surrounding circular motion dynamics. Owing to this…

There is currently little physics education literature examining thinking and learning in graduate education and even less literature characterizing problem solving among physics graduate students despite this being an essential professional skill for physicists. Given reports of discrepancies between physics problem solving in the undergraduate…

In the Next Generation Science Standards, energy is considered a "crosscutting concept" that bridges disciplinary boundaries and unites scientific disciplines. I examine how energy is represented in physics, biology, and chemistry contexts, using the reaction of molecular oxygen with sugar as an exemplar, and argue that disciplines…

Understanding particle motion in force fields (PMFF), which encompasses the nature of forces and the relationship between force and motion, is fundamental to mastering mechanics and electromagnetism. Effectively solving PMFF-related problems requires advanced reasoning skills and the ability to apply knowledge across diverse contexts. Despite…

Introductory physics is a gateway course that is required for many science, technology, engineering, and mathematics (STEM) majors. In introductory physics courses, women and racially minoritized students often have lower grades and higher attrition than white men. Inclusive teaching is widely recommended to ensure that all students have the…

In the ever-evolving landscape of education, the integration of Information and Communication Technology (ICT) has emerged as a transformative force, reshaping the way we teach and learn across various disciplines. Among these disciplines, physics stands as a particularly fertile ground for harnessing the power of ICT to enhance teaching…

Ion transport, involving the diffusion and migration of ions within the electrolyte, stands as a fundamental concept in electrochemistry and serves as the driving force for electrochemical reactions. Electric double layers are critical in the fields of electrochemical energy storage and chemical conversion, constituting a central focus of…

Students' performance in introductory physics at a university in Ghana was assessed over three academic years. The study covered two physics courses delivered to first-year students at the university. Two factors--access to tutorial sessions delivered outside of lecture times by teaching assistants and access to a formula sheet during the…

One expected outcome of physics instruction is that students develop quantitative reasoning skills, including strategies for evaluating solutions to problems. Examples of well-known "canonical" evaluation strategies include special case analysis, unit analysis, and checking for reasonable numbers. We report on responses from three tasks…

The problem here dealt with concerns physics education, and specifically the concept of force. The idea behind this research is that a historical approach to the teaching of such a notion is of great help for the students to fully understand the meaning of this basic physical magnitude. For, most of scientific concepts can be better grasped by the…

This study analyses the effectiveness of directed vs. minimally directed inquiry-based instructional approaches in improving students' attitudes toward physics. It specifically compares the impacts of cognitively guided instructional strategy (CGIS) and Cubing instructional strategy (CIS) on student attitudes. Using a pretest--post-test…

Previous research has found gender inequitable equipment usage across various lab course contexts. Few studies, however, have tested possible remediation strategies. In this work, we use hierarchical linear modeling to compare men and women's lab equipment usage in two group work structures across three course contexts. In one in-person course,…

Students' success in physics problem-solving extends beyond conceptual knowledge of physics, relying significantly on their mathematics skills. Understanding the specific contributions of different mathematics skills to physics problem-solving can offer valuable insights for enhancing physics education. Yet such studies are rare, particularly at…
