Rojas, Roberto – Physics Teacher, 2022
In one of the Faraday's experiments an electric current is induced in a conducting loop when a magnet in front of it moves towards or away from the loop. While the direction of circulation of the electric current in the loop has only two options, it depends on three experimental conditions that generate eight cases. Even though the Faraday law or…

An undergraduate laboratory was developed as part of the Drugs for Neglected Diseases "initiative's" Open Synthesis Network. This activity aimed to develop new compounds efficacious against visceral leishmaniasis. Students successfully synthesized, purified, and characterized ten different benzoxazole amides that were sent for biological…

Tarigan, Hendra Jaya – Physics Teacher, 2022
We describe here a low-cost experiment for introductory physics students where they compare the physical properties of aluminum and steel by means of cantilever oscillations. This, in turn, allows the students to improve their physical intuition about these materials. Further, the students can apply their physics and mathematics knowledge and…

Oss, Stefano – Physics Education, 2022
We propose an experiment in which the sound of a drumroll is recorded and analysed according to a simple mechanical model in which the inelastic restitution coefficient of the collision between the stick and drum surface, as well as the ongoing kinematics of the drumstick, are considered. The agreement shows that this model is well suited for…

Bhattacharya, Ahana; Chattopadhyay, K. N.; Adhikary, Chandan – Physics Education, 2022
A cost-effective method has been developed with utmost efficiency for the determination of density of a liquid. The experimental setup for this purpose is a Polyvinyl chloride (PVC) cylinder fitted with an overflow spout, a volume measuring cylinder, a wooden block along with a hook and a known mass taken from scientific weight box. For this…

Williams, Hollis – Physics Teacher, 2022
It is well known that Newton's work on mechanics depended in a crucial way on the previous observations of Galileo. The key insight of Galileo was that one can analyze the motion of bodies using experiments and mathematical equations. One experimental observation that roughly emerges from this work in modern terms is that two objects of different…

Wildan, Ardan; Yau, Chin Doong; Wijesinghe, Chamaka; Xiao, Kevin; Ng, Tuck Wah – Physics Teacher, 2022
The Van de Graaff (VDG) generator is ubiquitous in the physics laboratory, but the high-voltage discharges that emanate from it can cause user discomfort or damage to nearby electronics during experimentation. In this work, an augmented reality (AR) tool is developed to help students conduct the experiment safely. More specifically, it allows them…

Moya, Antonio Angel – Physics Teacher, 2022
Resistor--capacitor (RC) circuit labs help students, but most courses don't include them because of complications and cost. This work presents an easy and inexpensive Arduino-based lab on the charge and energy transfer between two capacitors with different values of the initial electric charge when they are connected through a resistor. Capacitors…

Aji, Mahardika Prasetya; Wulandari, Yuvita Kiki; Setiawan, Rudi; Karunawan, Jotti; Priyanto, Aan – Physics Education, 2022
In diffraction experiments, natural gratings often create uncommon diffraction patterns compared with those resulting from manufactured gratings. This study analyzed a unique diffraction pattern obtained by a grating from a flying termite wing. A ring-like diffraction pattern was formed because of the grating morphology from a flying termite wing,…

Wendy Chan; Larry Vernon Hedges – Journal of Educational and Behavioral Statistics, 2022
Multisite field experiments using the (generalized) randomized block design that assign treatments to individuals within sites are common in education and the social sciences. Under this design, there are two possible estimands of interest and they differ based on whether sites or blocks have fixed or random effects. When the average treatment…

Martin Rozman; Mojca Alif; Urban Bren; Miha Luksic – Journal of Chemical Education, 2022
Electrochromism encompasses reversible changes of material's optical properties (color, opacity) under the influence of an external electric current or applied voltage. The effect has been known for decades, but its importance continues to grow due to the rapid development of smart systems and the accompanying demand to build devices that consume…

Patrick I. T. Thomson; Paul Lamie – Journal of Chemical Education, 2022
This work further implements the "elements of inquiry" approach in a first-year undergraduate laboratory course, in a two-part inquiry sequence. In the first part of the sequence, students iteratively develop a "best-practice" TLC procedure. In the second part, students iteratively optimize a simple organic reaction using TLC,…

Dilek Özalp – International Journal of Science and Mathematics Education, 2025
Engaging in argument from evidence is a fundamental science practice. However, preservice elementary teachers have difficulty constructing arguments. They need effective experience with argument construction in science. Written argumentation is crucial in the process of science learning. One of the approaches for learning science through…

Anne Bertin-Renoux – Journal of Creative Behavior, 2025
This study explores the ways in which embodied creativity is conceived and implemented in french schools through the study of a corpus of professional articles published since the 1960s in a journal dedicated to physical education. The analysis focuses on pedagogical experiments to foster bodily creativity carried out in primary schools, as part…

Virtual laboratories (VLs) enable students to experiment, analyze data, or interact with digital content in a nonphysical space. VLs include simulations, electronic notebooks, videos, and augmented reality. As part of the "VL Project," comprising five academic institutions in Ireland, we sought to determine how VLs might enhance…
