Ayesha Farheen; Nia Martin; Scott E. Lewis – Chemistry Education Research and Practice, 2024
Education in organic chemistry is highly reliant on molecular representations. Students abstract information from representations to make sense of submicroscopic interactions. This study investigates relationships between differing representations: bond-line structures, ball-and-stick, or electrostatic potential maps (EPMs), and predicting partial…

Dewi Ayu Kencana Ungu; Mihye Won; David F. Treagust; Mauro Mocerino; Henry Matovu; Chin-Chung Tsai; Roy Tasker – Journal of Chemical Education, 2023
Magnetic molecular models help students explore molecular structures and interactions. In this study, we investigated how pairs of students used magnetic models to explore hydrogen bonding and the 6-fold symmetry of snowflakes. Fourteen first-year students enrolled in a chemistry unit participated in pairs. Students' interactions with the magnetic…

Effective spatial visualization and reasoning skills are often credited for students' success in science and engineering courses. However, students enrolled in these science courses are not always exposed to or trained properly on the best ways to utilize models to aid in their learning. Improving spatial visualization techniques with 3D models,…

Matovu, Henry; Won, Mihye; Treagust, David Franklin; Mocerino, Mauro; Ungu, Dewi Ayu Kencana; Tsai, Chin-Chung; Tasker, Roy – Chemistry Education Research and Practice, 2023
Recent studies have reported a growing trend of using student-generated diagrams for assessment in science teaching and research. However, many educators tend to use diagrams to explore students' perceptions of scientists and their work rather than explore conceptual understanding of abstract concepts. In this study, we used diagrams to…

Pedro J. Sánchez Gómez; Mauricio Suárez – Chemistry Education Research and Practice, 2025
We present an approach to the question of the educational relations between chemistry and physics based on the one hand, on an inferentialist account of scientific representation (Suárez M., (2024), "Inference and Representation. A Study in Modelling Science," Chicago and London: The University of Chicago Press). On the other, we have…

Frost, Stephanie J. H.; Yik, Brandon J.; Dood, Amber J.; Cruz-Ramírez de Arellano, Daniel; Fields, Kimberly B.; Raker, Jeffrey R. – Chemistry Education Research and Practice, 2023
A deep understanding of organic chemistry requires a learner to understand many concepts and have fluency with multiple skills. This understanding is particularly necessary for constructing and using mechanisms to explain chemical reactions. Electrophilicity and nucleophilicity are two fundamental concepts to learning and understanding reaction…

Dongju Zhang – Journal of Chemical Education, 2023
This review describes a computational chemistry exercise aimed at enhancing the understanding of upper-division undergraduates in organic chemistry and physical chemistry regarding the structures and aromaticities of cyclobutadiene and cyclooctatetraene. This exercise exposes students to chemical problems that require computational methods as a…

Matovu, Henry; Won, Mihye; Treagust, David Franklin; Ungu, Dewi Ayu Kencana; Mocerino, Mauro; Tsai, Chin-Chung; Tasker, Roy – Chemistry Education Research and Practice, 2023
In recent years, chemistry educators are increasingly adopting immersive virtual reality (IVR) technology to help learners visualise molecular interactions. However, educational studies on IVR mostly investigated its usability and user perceptions leaving out its impact on improving conceptual understanding. If they evaluated students' knowledge…

Kapici, Hasan Özgür – International Journal of Research in Education and Science, 2023
Being able to move between different representations levels (macroscopic, submicroscopic, and symbolic) is important to understand a chemical phenomenon meaningfully. The current study investigated how pre-service science teachers moved from symbolic representation to sub-microscopic representation. A total of 205 pre-service science teachers,…

Brown, Daniel; Uebergang, Tanya; Masters, Nicole; Towstoless, Michelle; Hayes, Alan; Hryciw, Deanne H.; Lexis, Louise; Tangalakis, Kathy – Advances in Physiology Education, 2023
Australia-wide consensus was reached on seven core concepts of physiology. The "movement of substances" core concept with the descriptor "the movement of substances (ions or molecules) is a fundamental process that occurs at all levels of organization in the organism" was unpacked by a team of three Australian physiology…

Farheen, Ayesha; Lewis, Scott E. – Chemistry Education Research and Practice, 2021
Representations are ubiquitous in chemistry. They are part of the chemistry language instructors use to communicate chemistry phenomenon to students. Literature calls in support of learning with multiple representations, but there is a pre-requisite for students to learn from a single representation. In this exploratory study, 1086 students in…

Marco Bortoli; Laura Orian – Journal of Chemical Education, 2023
Molecules and Computer: Chemistry Calculations in Class (MC[superscript 4]) is a computational laboratory intended for final-year high school or undergraduate students. The topic is the antioxidant potential of anthocyanidins, which is chemically related to their radical scavenging action via the mechanism of hydrogen atom transfer (HAT). This…

Most biology undergraduates learn about mutations in multiple classrooms throughout their college career. Understanding personalised genome test results, genome editing controversies, and the appearance of new variants of viruses or antibiotic resistant bacteria all require foundational knowledge about mutations. However, the abstract nature of…

McMillin, David R. – Journal of Chemical Education, 2020
In multielectron atoms or molecules, quantized electronic energy states known as term states provide a framework for interpreting absorption and emission spectra. Enumerating the term states associated with any particular electron configuration is possible using time-honored procedures, but the underpinnings of the methods do not always receive…

Raviolo, Andrés; Farré, Andrea S.; Schroh, Nayla Traiman – Chemistry Education Research and Practice, 2021
This article presents and discusses the results of a study that investigates university students' comprehension of the concept of molar concentration, following teaching and evaluation of the subject. The specific problems underlying learning of this concept have not yet been focused on in sufficient detail or depth. A "Reasoning with…
