Moon, Su Jin; Chen, Yu; Lee, Jiwon; Jung, Pyung Kang; Cho, Youngsaeng; Kim, Jung Bog – Physics Education, 2021
Students are well aware that when an electric current flows through a light bulb, it glows. As their grade increases, they have understood that electric current flows because electric charges move. Since the transfer of electric charges is not visible, students have many cognitive difficulties in understanding this process, and teaching materials…

Hahn, Marcelo; Cruz, Frederico; Carvalho, P. Simeao; Ferreira, Vanessa; Marques, Filipe; Macieira, Cláudio – Physics Education, 2021
Renewable energy is a trending topic due to its importance in today's society especially because of global warming. Because of its importance, this topic should be discussed at schools in an inclusive education environment. Experimental work is a very good activity to provide students effective conceptual discussions, but it is necessary to…

Ekey, Robert; Edwards, Andrea; McCullough, Roy; Reitz, William; Mitchell, Brandon – Physics Teacher, 2017
The incandescent bulb has been a useful tool for teaching basic electrical circuits, as brightness is related to the current or power flowing through a bulb. This has led to the development of qualitative pedagogical treatments for examining resistive combinations in simple circuits using bulbs and batteries, which were first introduced by James…

Alti, Kamlesh – Physics Education, 2017
Optical fibres play a very crucial role in today's technologies. Academic courses in optical fibres start at the undergraduate level. Nevertheless, student's curiosity towards optical fibres starts from the school level. In this paper, some fun experiments have been designed for both school and college students, which have some concrete…

Podschuweit, Sören; Bernholt, Sascha – Education Sciences, 2020
Conceptual knowledge is a crucial tool for students to understand scientific phenomena. Knowledge about the structure and function of mental concepts potentially helps science educators to foster the acquisition of this tool. Specifically, the coherence of students' mental concepts is an intensely discussed issue within the related conceptual…

Arlego, Marcelo; Fanaro, Maria de los Angeles – European Journal of Physics Education, 2017
In this work, we present a pedagogical strategy to describe the diffraction phenomenon based on a didactic adaptation of the Feynman's path integrals method, which uses only high school mathematics. The advantage of our approach is that it allows to describe the diffraction in a fully quantum context, where superposition and probabilistic aspects…

González, Manuel I. – Physics Education, 2017
Measuring voltage-current and voltage-power curves of a photovoltaic module is a nice experiment for high school and undergraduate students. In labs where real sunlight is not available this experiment requires a solar simulator. A prototype of a simulator using LED lamps has been manufactured and tested, and a comparison with classical halogen…

Etkina, Eugenia; Planinšic, Gorazd – Physics Teacher, 2014
This paper is the second in the series of LED-dedicated papers that have a goal to systematically investigate the use of LEDs in a general physics course. The first paper, published in the February 2014 issue, provided an overview of the course units where LEDs can be used and suggested three different ways of utilizing LEDs in an introductory…

Planinšic, Gorazd; Etkina, Eugenia – Physics Teacher, 2014
LEDs, or light-emitting diodes, are cheap, easy to purchase, and thus commonly used in physics instruction as indicators of electric current or as sources of light (Fig. 1). In our opinion LEDs represent a unique piece of equipment that can be used to collect experimental evidence, and construct and test new ideas in almost every unit of a general…
