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…

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…

Bonafe, Carlos Francisco Sampaio; Bispo, Jose Ailton Conceição; de Jesus, Marcelo Bispo – Biochemistry and Molecular Biology Education, 2018
Metabolism involves numerous reactions and organic compounds that the student must master to understand adequately the processes involved. Part of biochemical learning should include some knowledge of the structure of biomolecules, although the acquisition of such knowledge can be time-consuming and may require significant effort from the student.…

Elsworth, Catherine; Li, Barbara T. Y.; Ten, Abilio – Journal of Chemical Education, 2017
In this letter we present an innovative and cost-effective method of constructing crystal structures using Dual Lock fastening adhesive tape with table tennis (ping pong) balls. The use of these fasteners allows the balls to be easily assembled into layers to model various crystal structures and unit cells and then completely disassembled again.…

Murphy, Beth; Hedwall, Melissa; Dirks, Andrew; Stretch, Elizabeth – Science Teacher, 2017
Reading provides a unique window into the history and nature of science and the norms of scientific communication and supports students in developing critical-reading skills in engaging ways. Effective use of reading promotes a spirit of inquiry and an understanding of science concepts while also addressing expectations of the Common Core State…

Stull, Andrew T.; Gainer, Morgan; Padalkar, Shamin; Hegarty, Mary – Journal of Chemical Education, 2016
Mastering the many different diagrammatic representations of molecules used in organic chemistry is challenging for students. This article summarizes recent research showing that manipulating 3-D molecular models can facilitate the understanding and use of these representations. Results indicate that students are more successful in translating…

Vasquez, Thomas E., Jr.; Saldan~a, Cristina; Muzikar, Katy A.; Mashek, Debra; Liu, Jane M. – Journal of Chemical Education, 2016
This laboratory experiment provides undergraduate students enrolled in organic chemistry the opportunity to design and synthesize their own peptide, which is then tested for antimicrobial activity. After reading a primary scientific paper on antimicrobial peptides, students design and synthesize their own hexapeptide that they hypothesize will…

Robertson, Carol – Science Teacher, 2016
Deoxyribonucleic acid (DNA) is life's most amazing molecule. It carries the genetic instructions that almost every organism needs to develop and reproduce. In the human genome alone, there are some three billion DNA base pairs. The most difficult part of teaching DNA structure, however, may be getting students to visualize something as small as a…

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…

Enlow, Jessica L.; Marin, Dawn M.; Walter, Michael G. – Journal of Chemical Education, 2017
To improve polymer education for 9-12 and undergraduate students, a plastic electronics laboratory kit using polymer semiconductors has been developed. The three-module kit and curriculum use polymer semiconductors to provide hands-on inquiry activities with overlapping themes of electrical conductivity, light emission, and light-harvesting solar…

de Morais, Camilo de L. M.; Silva, Se´rgio R. B.; Vieira, Davi S.; Lima, Ka´ssio M. G. – Journal of Chemical Education, 2016
The binding constant and stoichiometry ratio for the formation of iron(II)-(1,10-phenanthroline) or iron(II)-o-phenanthroline complexes has been determined by a combination of a low-cost analytical method using a smartphone and a molecular modeling method as a laboratory experiment designed for analytical and physical chemistry courses. Intensity…

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…

Pentecost, Thomas; Weber, Sarah; Herrington, Deborah – Science Teacher, 2016
Research suggests that connecting the visible (macroscopic) world of chemical phenomena to the invisible (particulate) world of atoms and molecules enhances student understanding in chemistry. This approach aligns with the science standards and is fundamental to the redesigned AP Chemistry curriculum. However, chemistry is usually taught at the…
