In this article, we present an intriguing experimental exercise that does not fall foul of improper use of instrumentation. The activity is designed as an electronics exercise where the role of the instruments in the measurement of the RC time constant is considered. Essentially, we study the accuracy and precision of a measurement of the RC time…

The ground-breaking image of a black hole's event horizon, which captured the public's attention and imagination in April 2019, was captured using the power of interferometry: many separate telescopes working together to observe the cosmos in incredible detail. Many recent astrophysical discoveries that have revolutionized the scientific…

Many high schools, two-year colleges, and universities offer a conceptual physics course for non-science students who have to take a basic science course. The students often enter the course unmotivated and may eventually withdraw. So, how do we make the course interesting enough for these students to gain the knowledge we desire and, more…

Kinesthetic experiences in the classroom seek to engage students by muscle movement, touch, or some form of physical activity. In this article, I describe an active learning session wherein students develop a qualitative understanding of center of mass and support forces using their sense of touch. The set of activities detailed here is based on a…

Nowadays, inquiry-based learning is getting a lot of attention as an effective education method. Therefore, it has been researched and implemented in various countries. Inquiry-based learning has been used in various subjects such as biology, mathematics, social studies, and others. In order to encourage a smooth implementation of inquiry-based…

It is often challenging for physics instructors to dedicate time during a course to engage students in developing strategic approaches to learning in addition to problem-solving skills and content knowledge. In this work, we introduce a simple modification to our teaching practice with the purpose of fostering student development of self-regulated…

Quantum computing is a growing field at the intersection of physics and computer science. The goal of this article is to highlight a successfully trialled quantum computing course for high school students between the ages of 15 and 18 years old. This course was designed to bridge the gap between popular science articles and advanced undergraduate…

Equilibrium is an essential concept in undergraduate physics curriculum as it integrates Newton's laws and torque. The importance also comes from its wide applications in mechanics and biomechanics. Simulations of Back and Arms are developed mainly for the undergraduates who major in physical therapy and health sciences. They are implemented as…

Several new devices that demonstrate a variety of known phenomena in fluid dynamics are presented. These add on to a recent collection of demonstrations and follow the same design features as documented earlier (self-contained, easy to use, low cost). Descriptions are provided to enable replication by others, using readily available materials. The…

Introductory physics labs often focus on a series of common experiments intending to teach the student the measurement side of physics. While these experiments have the potential to be quite instructive, we observed that our students often consider them to be boring and monotonous, which often leads to them being uninstructive. To combat this, we…

One way that STEM (science, technology, engineering, and math) initiatives are being utilized is to encourage schools and teachers to integrate key science-based concepts into daily instruction. The reason is simple: it is more than just an instructional improvement or curricular enhancement; it is a research-based strategy that addresses the…

This paper describes a new lab experiment where students explore the magnetic force on a permanent magnet placed inside a short solenoid. This lab is the fourth experiment performed in the second semester of the calculus-based introductory physics course at Washington University in St. Louis. The experiment is performed using a speaker (which…

Undergraduate physics programs are increasingly facing pressure from university and college administration, industry, and funding agencies to improve training of our undergraduates. Increasingly, tertiary institutions have redefined their graduate profiles and mission statements to encompass more than just content knowledge, including skills that…

Models are at the heart of any physics discipline, and in recent decades physics education has shifted heavily toward teaching students how to think using models. Involving students in an investigation of a real phenomenon through measurements and the applications of models is an ideal learning experience for a physics student and is the aim of…

Abundant research leaves little question that pedagogical approaches involving active student engagement with the material, and opportunities for student-to-student discussions, lead to much better learning outcomes than traditional instructor-led, expository instructional formats, in physics and in many other fields. In introductory college…
