Euler, Elias; Prytz, Christopher; Gregorcic, Bor – Physics Education, 2020
In this paper, we present three types of activity that we have observed during students' free exploration of a software called "Algodoo," which allows students to explore a range of physics phenomena within the same digital learning environment. We discuss how, by responding to any of the three activity types we identify in the students'…

Yara C. Almanza-Arjona; Juan C. Durán-Álvarez; Ernesto Fernández-Urtusástegui; Claudia S. Castrejón-Perezyera – Journal of Chemical Education, 2022
The reaction rate and rate law are chemical kinetics concepts that undergraduate students have difficulty understanding and applying in real life. A further challenge is the overall reaction rate of consecutive reactions. Herein we present a creative teaching practice using the analogy-based approach to exploit the similarities between the…

Dias, Lucas A. L.; Faria, Roberto B. – Journal of Chemical Education, 2020
The use of symmetry is widespread in chemistry, as it is used for predictions of the number of allowed and forbidden absorptions in electronic, vibrational, and rotational spectroscopies; for predictions of the combination of atomic orbitals to produce molecular orbitals; and in many other chemical applications. One critical step in these…

Reeves, Shalaunda M.; Crippen, Kent J. – Journal of Science Education and Technology, 2021
Current technology has the capacity for affording a virtual experience that challenges the notion of a teaching laboratory for undergraduate science and engineering students. Though the potential of virtual laboratories (V-Labs) has been extolled and investigated in a number of areas, this research has not been synthesized for the context of…

McArdle, Patrick – Journal of Chemical Education, 2019
This article contrasts the normal method for drawing Lewis structures with a two-step systematic approach. The latter approach uses a known molecular connectivity and a knowledge of the number of valence electrons that each atom possesses to visualize bonds that are formed by pairing electrons, one from each atom. This process is repeated until at…

Hofmann, Andreas; Coster, Mark J.; Taylor, Paul – Journal of Chemical Education, 2019
The interactive generation of chemical-structure diagrams is an integral activity in the study of chemistry as well as in professional chemistry environments. For educational purposes in particular, the existence of suitable software tools free of charge is of great importance. Although a number of free chemical-drawing applications are currently…

Peng, Zhe; Jimenez, Jose L. – Journal of Chemical Education, 2019
KinSim is a research-grade, interactive, user-friendly, open-source, and visual software for kinetics modeling of environmental chemistry and other applications. Students without any computer-programming background and limited knowledge of environmental chemistry can use KinSim, which also includes multiple features and functionality dedicated to…

Smith-Peavler, Emily; Gardner, Grant E.; Otter, Ryan – Journal of College Science Teaching, 2019
Visual representations of physical and natural phenomena are important components of the teaching and learning of biology. In current undergraduate biology classrooms, visual representations are most often provided to students on PowerPoint slides. This study focuses on the use of, and perceptions about, PowerPoint in undergraduate introductory…

Lucas, Krista L. – Science Activities: Projects and Curriculum Ideas in STEM Classrooms, 2021
Molecular processes are highly complex, and are frequently difficult for high school and college students to comprehend. Because of the importance of visualization in learning, along with formative assessment of student understanding, utilization of 3D modeling software aids both educators and students alike. The activity described below required…

Smith, Garon C.; Hossain, Md Mainul – Journal of Chemical Education, 2017
"Complexation TOPOS" is a free software package to generate 3-D topographic surfaces ("topos") for metal-ligand complexometric titrations in aqueous media. It constructs surfaces by plotting computed equilibrium parameters above a composition grid with "volume of ligand added" as the x-axis and overall system dilution…

Tavares, Maurício T.; Primi, Marina C.; Silva, Nuno A. T. F.; Carvalho, Camila F.; Cunha, Micael R.; Parise-Filho, Roberto – Journal of Chemical Education, 2017
Teaching the molecular aspects of drug-target interactions and selectivity is not always an easy task. In this context, the use of alternative and engaging approaches could help pharmacy and chemistry students better understand this important topic of medicinal chemistry. Herein a 4 h practical exercise that uses freely available software as a…

Behmke, Derek; Kerven, David; Lutz, Robert; Paredes, Julia; Pennington, Richard; Brannock, Evelyn; Deiters, Michael; Rose, John; Stevens, Kevin – Proceedings of the Interdisciplinary STEM Teaching and Learning Conference, 2018
Spatial reasoning is defined as the ability to generate, retain, and manipulate abstract visual images. In chemistry, spatial reasoning skills are typically taught using 2-D paper-based models, 3-D handheld models, and computerized models. These models are designed to aid student learning by integrating information from the macroscopic,…

Smith, Garon C.; Hossain, Md Mainul – Journal of Chemical Education, 2017
Species TOPOS is a free software package for generating three-dimensional (3-D) topographic surfaces ("topos") for acid-base equilibrium studies. This upgrade adds 3-D species distribution topos to earlier surfaces that showed pH and buffer capacity behavior during titration and dilution procedures. It constructs topos by plotting…

Dias, Marco Adriano; Carvalho, Paulo Simeão; Ventura, Daniel Rodrigues – Physics Education, 2016
The Doppler effect is one of the recurring themes in college and high school classes. In order to contextualize the topic and engage the students in their own learning process, we propose a simple and easily accessible activity, i.e. the analysis of the videos available on the internet by the students. The sound of the engine of the vehicle…
