Direct linkGal, Susannah – Journal of Chemical Education, 2020
Creation of videos is one of the many ways faculty and teachers have had to cope with the limitations of teaching chemistry laboratory at this time of COVID-19 restrictions. In this communication, I describe ideas for videos generated by students in a class I taught entitled "Teaching of Biology". The students were required to interview…

Vasconcelos, Lucas; Kim, ChanMin – Instructional Science: An International Journal of the Learning Sciences, 2020
Scientific modeling and coding are critical skills to be integrated into K-12 instruction. Research has shown that preservice teachers are often ill-prepared for teaching scientific modeling, and lack opportunities to learn coding within teacher education programs. The present study reports the implementation of an instructional module and online…

Healy, Eamonn F.; Blade, Glenn – Journal of Chemical Education, 2020
While synthesis projects are not uncommon in the undergraduate organic curriculum, the problems posed are usually not representative of what chemists actually do. The sudden dislocation to online learning precipitated by the COVID-19 pandemic provided both a need and an opportunity to develop an organic synthesis project with greater relevance to…

Viennot, Laurence – International Journal of Science Education, 2020
Among the many decisions to be made in their teaching practice, physics teachers must decide how to explain each particular phenomenon to students. This study explores student teachers' ("STs") decision-making process when presented with several explanations of a physical phenomenon that might be used for teaching purposes. During…

Rodriguez, Jon-Marc G.; Harrison, A. Rayford; Becker, Nicole M. – Journal of Chemical Education, 2020
With recent curricular movements aimed at engaging students in science practices, more work is needed regarding evidence-based approaches for supporting students in developing competency in contexts such as chemistry. In this work, we focus on student engagement in constructing models related to graphical representations of reaction rate. Using…

Craig, Paul A. – Biochemistry and Molecular Biology Education, 2020
Lab courses are a significant component of biochemistry and molecular biology (BMB) education. In teaching the labs, we combine established techniques with novel approaches. Lab formats have also moved from traditional cookbook style labs to guided inquiry to course-based undergraduate research experiences (CUREs), where faculty bring their own…

dos Anjos, Rodrigo; Silva, Márcio Santos – Journal of Chemical Education, 2020
Biodiesel is an important biomass, largely employed in the transport sector and produced from vegetable oils. Additionally, waste cooking oils may be reused to produce biodiesel fuel, minimizing environmental pollution. A laboratory experiment that affords a widespread way to discuss degradation concepts and tools for used vegetable oil…

Roman, Claudia; Lazar, Liliana; García-Morales, Moisés – Journal of Chemical Education, 2020
Mass transfer separations are of extreme importance to professionals working in the chemical industry. For this reason, chemical engineering and industrial chemistry students are both taught these unit operations at the final years of their study programs. The traditional way of carrying out their design is based on the use of deterministic…

Celestino, Teresa; Marchetti, Fabio – Journal of Chemical Education, 2020
This paper focuses on system concept use in teaching either chemical core concepts or interdisciplinary chemistry-related topics. The system concept is important in order to develop global competences, and chemistry teaching plays a key role in this context. A questionnaire has been administered to two different samples, Italian teachers and…

Suárez, H. J. Herrera; Machado-Higuera, M.; Muñoz, J. H. – Physics Education, 2020
In this paper, the dynamic case of a system made up of two blocks connected by a string over a smooth pulley is revisited. One mass lies on a horizontal surface without friction, and the other mass has a vertical displacement. The motion equation is obtained and its solution is determined using the "Mathematica" package. Also an…

In this article, we propose an analysis of the state of, and trends in, the field of conceptual change research in science education through the lens of its models. Using a quantitative approach, we reviewed all conceptual change articles (n = 245) published in five major journals in the field of science education in search of the support that…

Nuryantini, Ade Yeti; Nuryadin, Bebeh Wahid – Physics Education, 2020
The vector of aircraft motion and analysis using FlightRadar24 and Tracker motion analysis has been investigated and studied. The straight, turning and circular aircraft motion were recorded from www.flightradar24.com using a commercial desktop video recording. Then, the video of the aircraft motion was analyzed using Tracker 5.1.1 to determine…

Tél, T.; Vinze, M.; Jánosi, I. M. – Physics Education, 2020
When injecting dye into a vortex, one finds that the dye remains captured around the vortex core over minutes, despite the fact that the vortex (and the dyed region) is strongly time-dependent. According to a recent theory, three-dimensional time-dependent vortices should be defined as rotating, material-holding regions of the fluid. Vortices…

Pirbhai, M. – Physics Education, 2020
Measuring the "e/m" ratio is a classic experiment in the physics curriculum. We show that smartphones can reliably measure the magnetic field strengths involved. Moreover, phone cameras and the image-processing software Tracker can make determining the charge-to-mass ratio of the electron more accurate.

Heck, André; Uylings, Peter – Physics Education, 2020
The fact that a bungee jumper can reach an acceleration greater than the acceleration of gravity is, also from a physics point of view, intriguing. Taking only gravity into account, it can be explained by applying conservation of energy or by deriving carefully the equation of motion in a Newtonian approach. In this article we show how it can be…
