Nyirahabimana, Pascasie; Minani, Evariste; Nduwingoma, Mathias; Kemeza, Imelda – Journal of Science Education and Technology, 2023
Physics education has been identified as one of the public sectors that are mostly influenced by technological developments. This paper adopted the quasi-experimental pre- and post-test design to assess the effects of multimedia-aided technologies (MAT) on undergraduate students' performance in quantum physics (QP) at the University of Rwanda…

Bonsignore, Gaetano; Agnello, Simonpietro; Cannas, Marco; Gelardi, Franco; Gallitto, Aurelio Agliolo – Physics Teacher, 2020
Energy consumption in the world is increasing more and more due to the huge energy request coming from emerging countries such as China, India, etc. To face the challenge of sustainability, a solution may be the use of solar energy, since it is the most abundant renewable energy source on Earth. The electromagnetic energy coming from the Sun can…

Pfaender, J.; Gratton, L. M.; Rosi, T.; Onorato, P.; Malgieri, M. – Physics Teacher, 2022
In the last decades spectroscopy began to play an essential role in physics education research with the recognition that atomic spectra constitute a good occasion to study the concepts of quantum mechanics. Moreover, activities in which atomic spectra are studied in order to understand star structure and evolution have proved particularly engaging…

Savall-Alemany, Francisco; Guisaola, Jenaro; Cintas, Sergio Rosa; Martínez-Torregrosa, Joaquín – Physical Review Physics Education Research, 2019
Research has highlighted difficulties experienced by students when studying quantum physics in introductory courses. In this paper, we present a teaching and learning sequence (TLS) aiming at introducing a quantum model of emission and absorption of radiation and we assess its impact on the students' learning about atomic spectra. The TLS has been…

Ayene, Mengesha; Krick, Jeanne; Damitie, Baylie; Ingerman, Ake; Thacker, Bath – International Journal of Science and Mathematics Education, 2019
A detailed investigation of student conceptions of quantum phenomena is needed, both to characterize student understanding of quantum concepts and to inform how we might teach quantum mechanics (QM). In this vein, in-depth semi-structured interviews were conducted with 35 students who majored in physics and received university-level QM…

Savall-Alemany, Francisco; Domènech-Blanco, Josep Lluís; Guisasola, Jenaro; Martínez-Torregrosa, Joaquín – Physical Review Physics Education Research, 2016
Our study sets out to identify the difficulties that high school students, teachers, and university students encounter when trying to explain atomic spectra. To do so, we identify the key concepts that any quantum model for the emission and absorption of electromagnetic radiation must include to account for the gas spectra and we then design two…

Pinochet, Jorge – Physics Education, 2018
In 1974, Stephen Hawking theoretically discovered that black holes emit thermal radiation and have a characteristic temperature, known as the "Hawking temperature." The aim of this paper is to present a simple heuristic derivation of the Hawking temperature, based on the Heisenberg uncertainty principle. The result obtained coincides…

Balta, Nuri – International Journal of Science and Mathematics Education, 2018
This study is a detailed look at the level of understanding of fundamental ideas about blackbody radiation (BBR) among physics teachers. The aim is to explore associations and ideas that teachers have regarding blackbody radiation: a concept used routinely in physics and chemistry, which is necessary to understand fundamentals of quantum physics.…

Kizilcik, Hasan Sahin; Yavas, Pervin Ünlü – Journal of Education and Training Studies, 2017
The aim of this study is to identify the opinions of pre-service physics teachers about the difficulties in introductory quantum physics topics. In this study conducted with twenty-five pre-service physics teachers, the case study method was used. The participants were interviewed about introductory quantum physics topics. The interviews were…

Blanchard, Paul A. – 1976
This booklet is part of an American Astronomical Society curriculum project designed to provide teaching materials to teachers of secondary school chemistry, physics, and earth science. A Basic Topics section discusses atomic structure, emphasizing states of matter at high temperature and spectroscopic analysis of light from the stars. A section…

Gingras, Yves – Science & Education, 2015
In order to show how formal analogies between different physical systems play an important conceptual work in physics, this paper analyzes the evolution of Einstein's thoughts on the structure of radiation from the point of view of the formal analogies he used as "lenses" to "see" through the "black box" of Planck's…

Schneider, Elia M.; Bärtsch, Amadeus; Stark, Wendelin J.; Grass, Robert N. – Journal of Chemical Education, 2019
A simple synthesis of fluorescent carbon quantum dots from lemon juice is described to introduce advanced high-school students and undergraduate college students to nanoparticle synthesis and quantum dots. The synthesis is based on the carbonization of lemon juice using only a hot plate stirrer. Column chromatography is used to separate different…

Ford, Kenneth W. – Physics Teacher, 2018
Many teachers like to introduce the Bohr atom toward the end of an introductory physics course. This is an excellent idea, given the historic importance of Bohr's 1913 work, which provided the bridge from Planck's quantized interaction of matter and radiation (1900) to the full theory of quantum mechanics (1925-28). Unfortunately, the version of…

Charlton, Michael; Eriksson, Stefan; Isaac, C. Aled; Madsen, Niels; van der Werf, Dirk Peter – Physics Education, 2013
We describe recent experiments at CERN in which antihydrogen, an atom
made entirely of antimatter, has been held in a magnetic minimum neutral
atom trap and subjected to microwave radiation to induce a resonant
quantum transition in the anti-atom. We discuss how this, the first
experiment to observe an interaction between an antihydrogen atom and…

Likar, A.; Razpet, N. – European Journal of Physics, 2009
The dipole radiation from an oscillating charge is treated using the Hamiltonian approach to electrodynamics where the concept of cavity modes plays a central role. We show that the calculation of the radiation field can be obtained in a closed form within this approach by emphasizing the role of coherence between the cavity modes, which is…
