Rusk, Fredrik; Rønning, Wenche – Education Inquiry, 2020
The relationship between learning and group work is often treated as self-evident, but the finer workings of this relationship require further study into the social organisation of group work. The aim of the research that forms the basis for the current article is to locate, describe, and gain new understanding of how peers organise their group…

Putranta, Himawan; Wiyatmo, Yusman; Supahar, X. X.; Dwandaru, Wipsar Sunu Brams – Physics Education, 2020
Physics learning cannot be separated from the existence of physics measuring instruments, but their existence in schools are very limited. Therefore, creativity and innovation are needed to develop physics measuring instruments that are easily accessible by schools. This research aims to design and construct a liquid density measuring instrument…

Vangunten, Matthew T.; Walker, Uriah J.; Do, Han G.; Knust, Kyle N. – Journal of Chemical Education, 2020
We demonstrate that the simplicity of preparing functional microfluidic devices using 3D printing is well suited for undergraduate laboratories. Educational experiments utilizing non-paper-based microfluidic devices are often relegated to well-equipped, resource rich universities because traditional fabrication techniques require specialized and…

An, Jiwoo; Poly, Laila-Parvin; Holme, Thomas A. – Journal of Chemical Education, 2020
In general chemistry laboratories, students learn practical laboratory skills through hands-on activities and are exposed to new scientific instruments. However, these instruments are often viewed as black boxes for various reasons, where students do not know how to use them or what the instruments are capable of. This tendency is likely to induce…

Shellito, Cindy – Journal of College Science Teaching, 2020
Students in introductory college science courses often have a simplified understanding of the scientific method. To introduce students to the complexity of the scientific process and the value of empirical observations, I implemented a semester-long assignment that required introductory-level college science students to build and calibrate weather…

Greenslade, Thomas B., Jr. – Physics Teacher, 2020
One of the memories of my freshman year at Amherst was a lecture in the required physics/calculus course in which Arnold Arons quoted Isaac Newton on standing on the shoulders of giants. Now that I have spent my physics career, I still use the same quote, but now apply it to the eponymous apparatus that has been designed by the giants in our field.

Tao, Fujun; Garcia, Alma Valenzuela; Xiao, Ting; Zhang, Yuliang; Yin, Yansheng; Chen, Xiaobo – Journal of Chemical Education, 2020
Interfacial solar vapor generation has recently drawn much attention because of its high solar-to-vapor generation efficiency. Here we introduce the basic experimental procedures and analysis for undergraduates to perform such an experiment to catch up with the cutting-edge research wave. Interfacial solar vapor generation employs an interfacial…

Deja, Katarzyna; Adamowski, Lukasz; Kirejczyk, Marek; Marcinkowska-Sanner, Maja; Gasowska, Martyna – Physics Education, 2020
This article presents the Polish project entitled 'Detektory dla Szkol' ('Detectors for Schools', throughout the paper referred to as 'the programme'). It was developed at the Education and Training Division of the National Centre for Nuclear Research (Narodowe Centrum Badan Jadrowych, NCBJ) in Poland. The programme allows the schools to borrow…

Liu, Juhong Christie; Johnson, Elizabeth – TechTrends: Linking Research and Practice to Improve Learning, 2020
Video and interactive media provide visual exposition and review for students to formulate cognitive representations where learning and reflection take place, especially in science laboratories. More inclusively, open educational resources (OER) with interactive content can facilitate access to media-enhanced learning. This paper reports part of a…

Schoeddert, Alex; Babooram, Keshwaree; Pelletier, Sarah – Journal of Chemical Education, 2019
A low-cost and easy-to-use water recirculation system for a condenser apparatus was designed and installed in an organic chemistry teaching laboratory. Relying on gravity and a small pump for water circulation, it supplies four stations simultaneously. The water recirculation system works very well with condensers used for distillation and reflux…

Hahn, Marcelo Dumas; Cruz, Frederico Alan de Oliveira; Carvalho, Paulo Simeão – Physics Teacher, 2019
When sound waves are taught at the secondary level, the speed of propagation of sound is one of the most important characteristics to be analyzed. However, it is very common in textbooks that the value of sound speed in air is considered constant regardless of the experimental conditions. The great question is that since sound is a mechanical…

Chen, Huai-Yi; Wu, Chien-Ming; Lai, Chiung-Hui – IEEE Transactions on Education, 2019
Contribution: Prior studies indicate that students experimenting with characterization of optical planar waveguides use expensive ready-made prism couplers without clear understanding about construction of the entire optical measurement system. This paper presents a cost-effective modified bright-mode prism coupler that helps students learn…

Krumphals, Ingrid – Physics Education, 2019
The main objective of this paper is to provide an explanation on a conceptual level of how the Mirascope and the occurring image formation work. The physics behind a Mirascope--a well-known device consisting of two concave mirrors--is very complex. In literature, only either high level or very simplified and deficient explanations can be found.…

Polácek, Luboš; Jurmanová, Jana; Navrátil, Zdenek – Physics Education, 2019
A pair of galvo mirrors reflecting light from a laser pointer is suggested for use as a school demonstration of Lissajous figures. The device is small, cheap and easy to assemble. Combined with a two-channel waveform generator, a full spectrum of excellently stable Lissajous figures can be generated (concerning frequency ratio, amplitude ratio and…

Wijaya, P. A.; Fauzi, U.; Latief F. D. E. – Physics Education, 2019
The air drag constant for different nose shapes of projectiles is determined with the help of a simple method combining a projectile launcher, video tracking technique and spreadsheet computer code for simulating the motion. A projectile launcher with low-cost components is developed to study air drag in projectile motion. The launcher is based on…
