Angela Bassoli – Journal of Chemical Education, 2024
Organic molecules are invisible objects, but they can be visualized and manipulated by using molecular models. The object-based learning (OBL) approach, which is an educational tool developed for museums and collection items, is tailored and applied to a first-year bachelor course of organic chemistry. At the beginning of the course, each student…

Karaismailoglu, Fatma; Yildirim, Mehtap – Biochemistry and Molecular Biology Education, 2023
This article presents the integration of Tinkercad, a free online modeling program that allows students to model molecular genetic concepts, into the distance learning process. The students had the opportunity to learn molecular genetics in a fun and more efficient way in spite of the limitations of the COVID-19 lockdown, and, in this respect, it…

Michael A. Everest; Abigail J. Toves; Melissa S. Reeves – Journal of Chemical Education, 2023
We have developed a guided-inquiry laboratory exercise in which students perform viscosity measurements to infer the structure of poly(vinyl alcohol) (PVA) in aqueous solution. The activity combines both experiments and modeling. In the experimental portion of the exercise, students measure the viscosity of several solutions of PVA with differing…

Sarah N. Abdo; Jeremy L. Hsu; Constantine Kapetanakis; Dina L. Newman; L. Kate Wright; Jennifer Bailey – Journal of Chemical Education, 2024
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,…

Jiro Kondo; Shota Nakamura – Journal of Chemical Education, 2023
The use of molecular models in chemistry and biochemistry classes is very effective in helping students understand covalent bonds and the chemical structure of molecules. However, conventional molecular models cannot represent intermolecular interactions such as hydrogen bonds and electrostatic interactions. Herein, we describe 3D printed…

Yujie Dang; Rui Wei; Jianye Wei – Journal of Chemical Education, 2024
Understanding the general ideas and methods of detecting molecular structures is essential in high school chemistry. However, there is a need for more practical activities in teaching. A hands-on activity was designed in this study, which uses flexible foam balls and long sticks such as knitting needles to imitate how scientists construct the 3D…

Neha Sharma; Bharti Badhani; Bhashyam Vaijayanthi; Priyanka Aggarwal; Anshika Gupta – Journal of Chemical Education, 2023
The introduction of Computational Chemistry via "Molecular Modelling and Drug Design" course at undergraduate level has opened wide possibilities for students to expand their knowledge of quantum chemistry, organic reaction mechanisms, protein-ligand interactions, drug design, and probable "in vivo" behavior of drug candidates.…

Mihasan, Marius – Biochemistry and Molecular Biology Education, 2021
The structure and function of biomolecules relationship is the hallmark of biochemistry, molecular biology, and life sciences in general. Physical models of macromolecules give students the possibility to manipulate these structures in three dimensions, developing a sense of spatiality and a better understanding of key aspects such as atom size…

Cruz-Guzmán, Marta; García-Carmona, Antonio; Criado, Ana María – Canadian Journal of Science, Mathematics and Technology Education, 2023
Prospective preschool teachers (PPTs) need to have learning experiences with the practice of scientific modelling to be able to design appropriate lessons as teachers. In the literature on research in science education, scarce experiences of PPTs in scientific modelling can be found. This study aims to fill the knowledge gap about PPTs'…

Hootan Roshandel; Matthew Shammami; Shiyun Lin; Yin-Pok Wong; Paula L. Diaconescu – Journal of Chemical Education, 2023
The rise of virtual and online education in recent years has led to the development and popularization of many online tools, notably three-dimensional (3D) models and augmented reality (AR), for visualizing various structures in chemical sciences. The majority of the developed tools focus on either small molecules or biological systems, as…

Elijah St. Germain – Journal of Chemical Education, 2025
Many approaches to teaching Newman projections and conformational manipulation rely on lecturing using only two-dimensional representations. While molecular models are recognized as useful learning tools, students are often left to figure out how to use them during the initial learning process. The availability of basic online molecular models…

Quayson, Claudia; Kwarteng, Twumasi Ankrah; Koranteng, Ernest; Hanson, Ruby – Science Education International, 2022
The study diagnosed chemistry teacher trainees' difficulties in naming and writing structures of spiro and bicyclic compounds. The case study design was conducted in a constructivist environment to enhance chemistry teacher trainees' ability to construct, represent, and interpret the structural formulae of spiro and bicyclic compounds. Purposive…

Miranda, Ana Carolina Gomes; Pazinato, Maurícius Selvero – Problems of Education in the 21st Century, 2023
The focus of the present study is the learning processes of concepts related to hydrogen bonds, which were developed using a didactic sequence (DS). Based on the perspective of Imre Lakatos, it was observed whether the explanatory models created by upper-secondary students form progressive transition sequences, which are similar to what Lakatos,…

Adrienne M. Pesce; Daniel B. King – Journal of Chemical Education, 2023
Novice chemists often struggle with the highly visual nature of some chemistry topics. To make visually demanding concepts, such as isomerism and stereochemistry, more accessible to students, chemistry instructors have long recommended the use of molecular model kits as visual aids. However, studies pertaining to student model usage have shown…

H. Martin; E. Eisner; J. K. Klosterman – Journal of Chemical Education, 2023
3D printers have facilitated a wealth of 3D printed molecular models illustrating key structural concepts for student learning. However, general adoption of 3D printed models in the organic chemistry classroom proceeds slowly as the majority of consumer-grade 3D (fused deposition modeling (FDM) and resin) printers are inherently monochromatic,…
