Woo, Yura; Ju, Young-Gu – Physics Education, 2019
In this paper, we present the details of the development of a smartphone spectrometer for education using a 3D printer and characterized the performance by comparison with a paper craft spectrometer. The optical design and the narrow slit used in the build resulted in the formation of accurate images of the slit on the image sensor leading to a…

Koura, Hiroyuki – Physics Education, 2014
Three-dimensional (3D) nuclear charts were created using toy blocks, which represent the atomic masses per nucleon number and the total half-lives for each nucleus in the entire region of the nuclear mass. The bulk properties of the nuclei can be easily understood by using these charts. Subsequently, these charts were used in outreach activities…

Balazovic, Marek; Tomasik, Boris – Physics Education, 2012
In the 1960s, Tanzanian student Erasto Mpemba and his teacher published a paper with the title "Cool?" in this journal (Mpemba and Osborne 1969 "Phys. Educ." 4 172-5). They claimed that hot water freezes more quickly than cold water. The paper not only led to a wave of discussion, and more publications about this topic, but also to a whole series…

Dvorak, Leos; Planinsic, Gorazd – Physics Education, 2012
A simple charge indicator with bipolar transistors described recently enables us to perform a number of experiments suitable for high-school physics. Several such experiments are presented and discussed in this paper as well as some features of the indicator important for its use in schools, namely its sensitivity and robustness, i.e. the…

Gagnon, Michel – Physics Education, 2011
Mainly used in the 1960s, bubble chambers played a major role in particle physics. Now replaced with modern electronic detectors, we believe they remain an important didactic tool to introduce particle physics as they provide visual, appealing and insightful pictures. Sadly, this rare type of detector is mostly accessible through open-door events…

Gianino, Concetto – Physics Education, 2008
In this article, four examples of possible lessons on energy levels for high school are described: a particle in a box, a finite square well, the hydrogen atom and a harmonic oscillator. The energy levels are deduced through the use of the steady-state condition and the de Broglie relationship. In particular, the harmonic oscillator energy levels…

Houari, Ahmed – Physics Education, 2007
Many researchers and lecturers have reported that the concept of the mole and Avogadro's number are frequently misunderstood by first-year science students. For this reason, it is highly recommended to introduce this fundamental number to high school and freshman science students as clearly as possible. Therefore, it is pedagogically very useful…

Kovacevic, Milan S.; Djordjevich, Alexandar – Physics Education, 2006
Analogy is a potent tool in the teacher's repertoire. It has been particularly well recognized in the teaching of science. However, careful planning is required for its effective application to prevent documented drawbacks when analogies are stretched too far. Befitting the occasion of the World Year of Physics commemorating Albert Einstein's 1905…

Daniel, Michael – Physics Education, 2006
Quantum fields are introduced in order to give students an accurate qualitative understanding of the origin of Feynman diagrams as representations of particle interactions. Elementary diagrams are combined to produce diagrams representing the main features of the Standard Model.

Drexler, K. Eric – Physics Education, 2005
Fabrication techniques are the foundation of physical technology, and are thus of fundamental interest. Physical principles indicate that nanoscale systems will be able to fabricate a wide range of structures, operating with high productivity and precise molecular control. Advanced systems of this kind will require intermediate generations of…

Imai, Izumi; Kamata, Masahiro; Miura, Naosuke – Physics Education, 2003
Kinetic models of a gas can be hard for students to understand. Typical tools do not display events at the microscopic level, yet computer simulations of the molecules lack a hands-on aspect. Here a new tool is described that combines the squeezing of a syringe with a computer simulation, and it is shown that this has worked well in class for both…

Pascolini, A.; Pietroni, M. – Physics Education, 2002
We report on an educational project in particle physics based on Feynman diagrams. By dropping the mathematical aspect of the method and keeping just the iconic one, it is possible to convey many different concepts from the world of elementary particles, such as antimatter, conservation laws, particle creation and destruction, real and virtual…
