The percentage of women receiving bachelor's degrees in physics (25%) in the U.S. lags well behind that of men, and women leave the major at higher rates. Achieving equity in physics will mean that women stay in physics at the same rates as men, but this will require changes in the culture and support structures. A strong sense of belonging can…

Physical education in colleges plays an increasingly important role in cultivating high-quality innovative talent. The main factors that affect college students' approaches to learning physics remain unknown. This study examined the relationships among college engineering students' epistemic views of physics, conceptions of learning physics, and…

This paper presents important findings that were observed as interconnected key elements of high-quality co-teaching of a physics course for pre-service science teachers while the collaborating faculty experienced a "pedagogical convergence." This pedagogical convergence is akin to the "conceptual convergence" that Roschelle…

We reexamine the approximate formula for the path difference in the double-slit interference experiment, establish its limits of applicability from a geometric perspective and discuss its validity for the two-source interference of acoustic and surface waves.

George M. Hopkins (1842-1902) wrote a series of articles on demonstrating physical phenomena in the "Scientific American" during the last years of the 19th century. These were collected in a book, "Experimental Science," that was first published in 1890, with revisions in 1892 and 1902. It must have been well received, for the…

There is no shortage of great pedagogical tools available, but many require considerable investment of time and effort (and oftentimes money and equipment), which can be a significant barrier for already time-poor teachers. "Wonder Questions" is a pedagogical tool that is simple, flexible, and pedagogically powerful in three ways: (1) it…

Work and mechanical energy is a fundamental topic in introductory physics. Studies in existing literature have shown that students have difficulties in understanding work and mechanical energy, particularly the topic of work-energy theorem. To study students' knowledge integration in learning work and mechanical energy, a conceptual framework…

Background: Although there is an increasing recognition of the importance of critical thinking in science education across the world, the relevant research literature is extremely thin. There is an urgent need to generate more empirical evidence. Purpose: We examined two essential issues concerning critical thinking (the relationship between…

It can be difficult to find ways to motivate students while teaching a physics course for non-physics students. Students come to class with many different attitudes and preconceptions, some of which are detrimental to their learning. As physics educators, we strive for student engagement and motivation in course material no matter what type of…

The relativistic addition of velocities is usually introduced early in the study of Einstein's special theory of relativity. The equations are simple enough, but randomly chosen velocities lead to unwieldy calculations that can dishearten the student. This paper presents tables of velocity components in two dimensions, composed of five or fewer…

A key concept in current fluid dynamics and its applications to biology and technology is a phenomenon known as wetting. Wetting is familiar from everyday life and is simply the ability of a liquid to stay in contact with a solid surface. The wettability depends on the properties of the liquid and the solid and can be characterized by the static…

Transfer of structural math knowledge to physics is difficult for students. While research suggests various improvement techniques, enhancing parallelism of algebraic structures used in physics to those studied in mathematics courses seems underrepresented. This paper proposes an alternative way of introducing wave functions as a set of parametric…

Simulations can provide opportunities for engaged exploration in physics teaching and learning. Beyond the two-dimensional world of screen-based simulations, abstract concepts like vectors (for example, of electric fields) can frequently be visualized better in a three-dimensional virtual reality (VR) environment. These visualizations can be…

Students often face difficulties to understand Archimedes' principle and to apply it in everyday life. It is therefore necessary to explore a different teaching approach that addresses students' visual and auditory senses in a unique manner. The aim of this study was to determine the effect of using multiple representations on undergraduate…

This article provides a process to carefully evaluate the suitability of a content domain for which diagnostic classification models (DCMs) could be applicable and then optimized steps for constructing a test blueprint for applying DCMs and a real-life example illustrating this process. The content domains were carefully evaluated using a set of…
