ScottP. Buzzolani; Matthew J. Mistretta; Aleksandra E. Bugajczyk; Arun J. Sam; Samantha R. Elezi; Daniel L. Silverio – Journal of Chemical Education, 2025
The ability to extract structural information from a drawing of a molecule is key to being successful in organic chemistry. One source of difficulty for novices in interpreting structures is that hydrogens bound to carbon are represented implicitly in the often-used line-angle structures. Other representations that explicitly show hydrogens, such…

Kortemeyer, Gerd – Physics Teacher, 2023
Simulations can provide opportunities for engaged exploration in physics teaching and learning. Beyond the two-dimensional world of screen-based simulations, abstract concepts like vectors (for example, of electric fields) can frequently be visualized better in a three-dimensional virtual reality (VR) environment. These visualizations can be…

Kevin J. Krajcir; Emily K. Field; Bradley Fultz; Robin Buff; Jim Gann; Lorin A. Neuman-Lee – American Biology Teacher, 2024
Biological interactions and associations underlie life's processes at every level of organization. Here, we present a classroom activity that allows students to visualize and understand the connections within almost any biological system, from cell functions to ecological relationships. We recommend that instructors implement this activity to…

Yash Munnalal Gupta; Satwika Nindya Kirana; Somjit Homchan – Biochemistry and Molecular Biology Education, 2025
This short paper presents an educational approach to teaching three popular methods for encoding DNA sequences: one-hot encoding, binary encoding, and integer encoding. Aimed at bioinformatics and computational biology students, our learning intervention focuses on developing practical skills in implementing these essential techniques for…

George C. Lisensky; Omar M. Yaghi – Journal of Chemical Education, 2022
Metal organic frameworks (MOFs) can have open pore structures with high surface areas and applications in hydrogen storage, carbon dioxide capture, water harvesting from air, chemical separations, and catalysis. The chemical structure of these crystalline solids can initially appear daunting. Simplification by considering the arrangement of the…

Daniel A. Mak; Sebastian Dunn; David Coombes; Carlo R. Carere; Jane R. Allison; Volker Nock; André O. Hudson; Renwick C. J. Dobson – Biochemistry and Molecular Biology Education, 2024
Enzymes are nature's catalysts, mediating chemical processes in living systems. The study of enzyme function and mechanism includes defining the maximum catalytic rate and affinity for substrate/s (among other factors), referred to as enzyme kinetics. Enzyme kinetics is a staple of biochemistry curricula and other disciplines, from molecular and…

Roudhotul Fitria; Rio Sebastian – Anatolian Journal of Education, 2024
Representation plays an important role in helping students understand chemistry learning. This is due to the many chemical concepts that require visualization. Representation is something that still needs to be studied. So this study aims to see the development of representation research in chemistry education. The articles used in this study are…

Christoph Hoyer; Raimund Girwidz – Physical Review Physics Education Research, 2024
Vector fields are a highly abstract physical concept that is often taught using visualizations. Although vector representations are particularly suitable for visualizing quantitative data, they are often confusing, especially when describing real fields such as magnetic and electric fields, as the vector arrows can overlap. The present study…

Sveistrup, Michelle A.; Langlois, Jean; Wilson, Timothy D. – Anatomical Sciences Education, 2023
Spatial abilities (SAs) are cognitive resources used to mentally manipulate representations of objects to solve problems. Haptic abilities (HAs) represent tactile interactions with real-world objects transforming somatic information into mental representations. Both are proposed to be factors in anatomy education, yet relationships between SAs and…

Kaur, Jasjeet; Sodhi, Gurvinder S. – Science Activities: Projects and Curriculum Ideas in STEM Classrooms, 2023
It may be asserted that there is no more effective deterrent to crime than the certainty of detection. Equally true is that there is no surer way to establishing identity than by fingerprints. The detection of fingerprints at the scene of crime is therefore one of the most powerful tools available in casework investigations. However, if the crime…

Yamaguchi, Janet – Science and Children, 2023
This article describes how using a variety of differentiation strategies, such as listening to stories, visualizing scenarios, and performing tactile activities, can help fourth-grade students to conceive of and express examples of energy transfer.

Cle´mence Iacconi; Jonathan Piard; Elena Tosi-Brandi; Franc¸ois Azambourg; Marion Dubois; Vincent Cre´ance; Loi¨c Bertrand – Journal of Chemical Education, 2024
There is a gap between the importance of certain archeological material sources and their perception, both by professionals and by the general public. Textiles, for example, are essential to understanding practices that marked daily life and rituals in the past, but they have often been extremely degraded over time, particularly in temperate…

Blagotinšek, Ana Gostincar – Physics Teacher, 2023
Two misconceptions about the mechanism of image formation in the human eye are common among students and even in textbooks and other teaching materials. The first attributes all refraction to the eye lens; the second treats the eye as a pinhole camera. To reduce these persistent conceptions of students, a series of simple experiments is presented…

Vidak, Andrej; Šapic, Iva Movre; Hadžimehmedovic, Mirza – Physics Teacher, 2022
In the past decade, we have witnessed the emergence of a large number of different computer-based animations and simulations that have the goal to foster better learning of different physics topics. Past studies have shown many benefits of animations and simulations, but for their efficient usage it is very important that teachers are well…

Titration is an important experimental skill that every chemistry educator and learner must master. Titration is often the method of choice in the science laboratory courses in secondary and postsecondary schools. During acid-base titration, chemistry learners are always told about salt formation. However, a practical visualization of the salt…
