Mylott, Elliott; Kutschera, Elynne; Widenhorn, Ralf – Physics Teacher, 2019
Physics instruction for aspiring health care professionals, medical researchers, and biologists often fails to capture the interest of students. This is despite the many ways physics is used in research, diagnostics, and treatment. Universities are revising the introductory physics courses to be more relevant to pre-health students. Part of this…

Richards, A. J. – Physics Teacher, 2020
As students learn physics, they are often required to reason about the behavior of macroscopic and microscopic phenomena, and to synthesize prior knowledge from several different areas of physics to construct understanding of new ideas. This can be a tremendously difficult cognitive task for novice students, especially when the unfamiliar…

Pawl, Andrew – Physics Teacher, 2020
Examination of my students' individual gains on the Force Concept Inventory (FCI) over the course of several semesters led to the realization that student pretest knowledge on certain key questions appeared to be correlated to enhanced gain during the class. Acting under the hypothesis that early intervention aimed at helping the class perform…

Ogawara, Yasuo – Physics Teacher, 2020
When we teach thermodynamics, a vacuum container used to keep food isolated from air is a cheap and interesting teaching device. There are some experiments already described in the literature and we can also find videos of demonstrations on YouTube. At the same time, there is increasing interest in how to utilize smartphones in physics…

McGinness, Lachlan; Dührkoop, Susanne; Woithe, Julia; Jansky, Alexandra – Physics Teacher, 2019
There is an increasing emphasis on fundamental particles, including quarks, in the high school physics classroom. However, many teachers might not feel comfortable teaching particle physics because it is a highly abstract and complex topic, and there are few hands-on activities to help teachers bring it into the classroom. In 2010, a…

Redish, Edward F. – Physics Teacher, 2021
Making meaning with math in physics requires blending physical conceptual knowledge with mathematical symbology. Students in introductory physics classes often struggle with this, but it is an essential component of learning how to think with math. Teaching the dimensionality of measured quantities and dimensional analysis (DA) is a valuable first…

Fuster, Gonzalo; Rojas, Roberto – Physics Teacher, 2021
The photoelectric effect consists of electrons emerging from the region near the inner surface of a metallic solid toward the outside vacuum, when the metal surface is illuminated. The effect depends on the frequency of the light waves and the properties of the metal surface. In particular, a minimum or "threshold" frequency of light is…

Kim, Minkyung; Kang, Wonseok; Kim, Jung Bog – Physics Teacher, 2021
Nearly everyone, including physics students, finds rainbows to be fascinating and much has been written about them. For example, in a 2020 paper, Kenneth Ford sets forth the basic theory of rainbows created by water droplets at the level of geometric optics and uses a graphical approach to address the question of the relative intensities of the…

Asadollahi, Zahra; Andrianarijaona, Vola M. – Physics Teacher, 2021
The eye should have a particular focal length in order to see an object. As there are many things to see, the focal length of the eye must vary because these things are not all at the same distance from the eye. We explore the eye accommodation from a geometrical optics point of view and present our results in this paper; the study includes a…

Henderson, Rachel; Sawtelle, Vashti; Nissen, Jayson Micheal – Physics Teacher, 2020
Many students across the United States enter college with aspirations of becoming a successful career scientist within the fields of science, technology, engineering, and mathematics (STEM). However, the number of bachelor's degrees awarded in physics has significantly lagged behind the number of bachelor's degrees awarded in the other STEM…

Kumar, Alok – Physics Teacher, 2023
Science does not belong to just one civilization, one culture, one country, or one gender; it belongs to all who want to unfold the mysteries of nature. Most scientists agree that science currently is, and indeed always has been, international and multicultural in character. Our teaching at all levels should reflect this multiculturalism as part…

Eichenlaub, Mark – Physics Teacher, 2022
There is a close connection between simple harmonic motion and uniform circular motion. This connection is widely taught and included in standard textbooks. Here, we exploit this connection to simultaneously derive two results from introductory mechanics: the period of a mass-spring system and the centripetal acceleration formula. Previously…

Dorsel, Dominik; Staacks, Sebastian; Heinke, Heidrun; Stampfer, Christoph – Physics Teacher, 2022
As smartphones have become a part of our everyday life, their sensors have successfully been used to allow data acquisition with these readily available devices in a variety of different smartphone-based school experiments. Such experiments most commonly take advantage of the accelerometer and gyroscope. A less frequently used sensor in…

Balta, Nuri – Physics Teacher, 2022
In introductory texts, some "special" rays are selected to draw the image produced by lenses and mirrors. After teaching special rays, students usually ask how to draw an arbitrary ray. One method for drawing an arbitrary ray is the "tilted principal axis." As an example, the tracing of an arbitrary ray in diverging lens is…

Oh, Woo-Jin; Park, Hogul; Paik, Seoung-Hey – Physics Teacher, 2022
Science is the activity of studying the natural world in various ways to construct theories and models to explain phenomena. Windschitl et al. reported that model-based inquiry includes the connection between observable aspects of the target phenomenon and conjectured underlying causal processes. In addition, they insisted that learners are…
