Baird, William H. – Physics Education, 2022
The United States' Global Positioning System (GPS), and similar geolocation systems such as Galileo, GLONASS, and Beidou are used by people all over the globe. Modern receivers of these global navigation satellite systems can track multiple satellites from different constellations. Casual, non-technical users are probably aware that the positional…

Atkin, Keith – Physics Education, 2022
This paper describes two examples of teaching situations in which the idea of infinity arises, and supports the conclusion that infinity is not a physical reality but a very powerful and useful mathematical device which facilitates modelling and the solution of problems in physics.

Fouad, Emadelden; Austin, Robert; Kryger, R. A.; Holton, Doug; Srinivasan, Sesha; Ngwa, Wilfred – Physics Education, 2022
The use of technology in higher education science classrooms rose significantly in the advent of the COVID-19 pandemic. In many universities, academic programs including introductory physics classes were taken online. Some institutions adopted online learning but also maintained face-to-face (F2F) laboratories when COVID-19 restrictions began to…

Hachmi, A.; El Moussaouy, A.; Ouariach, A.; Essaadaoui, R.; El Hadi, M.; Mommadi, O.; Kerkour-El Miad, A. – Physics Education, 2022
In this study that aims to motivate struggling students and helping them to improve their learning achievement, we designed and tested an E7-based approach in a virtual laboratory environment. We rely on cognitive load theory and self-determination theory to enable our approach to meet the cognitive and noncognitive needs of struggling students.…

Hughes, Stephen – Physics Education, 2022
Archimedes' principle is one of the foundation subjects in physics. Normally the principle is exemplified by reference to floating boats. However, Archimedes' principle also applies to objects embedded in waterlogged ground, which can lead to the surprising result of an object weighing several tons being lifted. A practical example is presented of…

Sarkar, Soumen; Chakrabarti, Surajit – Physics Education, 2022
In this experiment we have first determined the focal length of an equiconvex lens. We have observed that a real image can be formed by the lens on the same side of the source if the source is sufficiently strong. This is due to the reflection from the concave surface of the lens. We have measured these image distances for different object…

Williams, Hollis – Physics Education, 2022
We outline the basic theory behind white light interferometry and the workings of a typical light interferometer microscope. We study WLI images obtained for rough and smooth chrome steel spheres to illustrate the principle that curved rough surfaces can be imaged with such a device as long as the surface roughness is kept within certain limits.

Zhu, Lilin; Xiang, Gang – Physics Education, 2022
We report on the study of student difficulties regarding a heat engine in the context of a Stirling cycle by the method of measurement. An in-class test about a Stirling engine with a regenerator was taken by three classes, and the students were asked to perform one of the most basic activities--calculate the efficiency of the heat engine. Our…

Kaewkhong, Kreetha; Nguenyuang, Sunee; Intanate, Nampueng; Pewkam, Wichaya – Physics Education, 2022
This article investigates the optics conceptions of 228 Thai high school students in grades 10-12 when they attempted to explain how an object can be seen both in general and in a completely dark room. To elicit students' conceptions precisely, their confidence in giving reasons for the final two diagnostic questions is also considered. The study…

Levy, Smadar; Noga, Adi; Kapach, Zehorit; Yerushalmi, Edit – Physics Education, 2022
The instructional lab setting has been found to be dominated by prescribed tasks and pre-prepared lab kits. This was explained by teachers' need to guide students to simultaneously progress through a lab curriculum, which prompts them to standardize the lab experience. Nevertheless, prominent professional associations have persistently called to…

Cottle, Daniel – Physics Education, 2022
Three new physics teachers graduating from a university provider of initial teacher education in England were paired with a recently retired physics subject specialist teacher in order to provide informal mentoring during their first year of teaching. The aim of this was to explore if a mentoring intervention of this kind could support teacher…

Cross, Rod – Physics Education, 2022
If an empty coffee cup is spun on a horizontal surface about a vertical axis in an anti-clockwise direction, then the whole cup rotates slowly backwards, in a clockwise direction, about a vertical axis located outside the cup. Clues to this curious behaviour are presented by comparing it with other spinning objects.

Essiane, Salome Ndjakomo; Essama, Bedel Giscard Onana – Physics Education, 2022
The goal of this work is to build a low cost pedagogical device able to improve the comprehension of weather phenomena for African students in particular and in general for students across the world. This experimental and didactic device can be seen as an easy teaching tool to measure meteorological and climatic data. This structure is called a…

Cross, Rod – Physics Education, 2022
Oblique angle collisions of two penny coins on a smooth, horizontal surface were filmed with a video camera to investigate the physics of the collision process. If one of the coins is initially at rest, then the two coins emerge approximately at right angles, as commonly observed in billiard ball collisions and in puck collisions on an air table.…

Marcom, Guilherme Stecca; Villar, Renato Pacheco; Kleinke, Maurício Urban – Physics Education, 2022
Research on problem-solving strategies has been conducted since the 1940s. Experts and novices use different strategies in problem solving; the main difference is in the familiarity with which they face new problems. For multiple-choice problems, an analysis of distractors can provide possible clues about the resolution processes developed by…
