Juan Carlos Vega-Garzón; Duverney Chaverra-Rodriguez – Biochemistry and Molecular Biology Education, 2025
The COVID-19 pandemic affected a large range of in-person education activities in Colombia. This created great limitations in academic performance for students with reduced access to communication technologies and deepened the educational gaps in the country. This was particularly true for sciences such as biochemistry. In Colombia, molecular…

Hoover, Gabrielle C.; Dicks, Andrew P.; Seferos, Dwight S. – Journal of Chemical Education, 2021
In undergraduate chemistry curricula that include computational modeling, students may gain first-hand experience in both introductory and advanced applications of this technique. However, although students can be exposed to the predictive power of computational work, its capabilities are often limited to determining the intrinsic properties of…

Melanie B. Berkmen; Melisa Balla; Mikayla T. Cavanaugh; Isabel N. Smith; Misael Eduardo Flores-Artica; Abby M. Thornhill; Julia C. Lockart; Celeste N. Peterson – Biochemistry and Molecular Biology Education, 2025
Biochemistry and molecular biology students are asked to understand and analyze the structures of small molecules and complex three-dimensional (3D) macromolecules. However, most tools to help students learn molecular visualization skills are limited to two-dimensional (2D) images on screens and in textbooks. The virtual reality (VR) App Nanome,…

Jesús Erubiel Miguel-Gómez; Dennise Salazar; Miguel Reina – Journal of Chemical Education, 2023
Ludic-didactic material has systematically been proven to be a useful tool that enhances teaching and learning processes, at practically any educational level by reducing the stress level of students and creating a feeling of team spirit and trust. In chemistry courses, significant efforts have been made to improve the learning of intermolecular…

Kallepalli, Samaya; Johnson, Lydia; Mattson, Bruce – Journal of Chemical Education, 2021
Thomas Graham discovered the law that bears his name while studying gas diffusion into air and other gases. He also found that the same relationship held with gas effusion, the movement of gases through a pinhole into a vacuum. Modern understanding of diffusion and effusion is based on kinetic-molecular theory, and it is generally accepted that…

Emery, Patrick; Yezierski, Ellen J.; Page, Richard C. – Biochemistry and Molecular Biology Education, 2019
Visualizations are useful tools for helping students to understand chemistry concepts at the particulate level. A classroom activity was developed based on learning theory and evidence-based practices, combining protein visualization with thermodynamic parameters from differential scanning fluorimetry (DSF) data analysis. Coding of student…

Holbert, Nathan; Wilensky, Uri – Journal of the Learning Sciences, 2019
In this article we propose that educational game design should work to create games as objects-to-think-with--games that engage players in the exploration of and experimentation with personally interesting questions around domain-relevant representations. We argue that this design focuses on developing tools and interactions that the player can…

Lotter, Christine; Taylor, Laurie – Science Teacher, 2016
In the 2 day lesson presented in this article, students explain how ionic substances interact in solutions by developing and revising their own explanatory models. The lesson engaged students in three-dimensional learning through creating and revising their own models to explain the interaction of ionic substances and polar molecules in a closed…

Amy Kamarainen; Shari Metcalf; Tina Grotzer; Craig Brimhall; Chris Dede – International Journal of Designs for Learning, 2016
We describe a mobile augmented reality (AR) experience called Atom Tracker designed to help middle school students better understand the cycling of matter in ecosystems with a focus on the concept of conservation of matter and the processes of photosynthesis and respiration. Location-based AR allows students to locate virtual "hotspots,"…

Coppo, Paolo – Journal of Chemical Education, 2016
A 1 h classroom activity is presented, aimed at consolidating the concepts of microstates and Russell-Saunders energy terms in transition metal atoms and coordination complexes. The unconventional approach, based on logic and intuition rather than rigorous mathematics, is designed to stimulate discussion and enhance familiarity with quantum…

Parsons, Christopher J.; Salaita, Meisa K.; Hughes, Catherine H.; Lynn, David G.; Fristoe, Adam; Fristoe, Ariel; Grover, Martha A. – Journal of Chemical Education, 2017
"Group Intelligence" is an active learning, inquiry-based activity that introduces prebiotic chemistry, emergent complexity, and diversity's importance to adaptability across scales. Students explore the molecular emergence of order and function through theatrical exercises and games. Through 20 min of audio instruction and a discussion…

Bruck, Laura B. – Journal of College Science Teaching, 2016
The intermolecular forces activity presented in this article is designed to foster concept-building through students' use of concrete, manipulative objects, and it was developed to be pedagogically sound. Data analysis via pre- and posttesting and subsequent exam questions indicated that students who had the opportunity to participate in the…

Schubert, Frederic E. – Journal of Chemical Education, 2015
In this exercise, an actual chemical reaction, oxidation of iron in air, is studied along with a related analogue simulation of that reaction. The rusting of steel wool is carried out as a class effort. The parallel simulation is performed by students working in small groups. The analogue for the reacting gas is a countable set of discrete marble…

Scalfani, Vincent F.; Turner, C. Heath; Rupar, Paul A.; Jenkins, Alexander H.; Bara, Jason E. – Journal of Chemical Education, 2015
The emergence of 3D printing has dramatically advanced the availability of tangible molecular and extended solid models. Interestingly, there are few nanostructure models available both commercially and through other do-it-yourself approaches such as 3D printing. This is unfortunate given the importance of nanotechnology in science today. In this…

Oliveira, Daniela Kênia B. S.; Justi, Rosária; Mendonça, Paula Cristina Cardoso – International Journal of Science Education, 2015
This paper discusses the use of non-verbal representations in a modelling-based science teaching context, in which argumentative and explanatory situations occur. More specifically, we analyse how the students and teacher use representations in their discourse in modelling activities, and we discuss the relationships between the functions of these…
