This study examines secondary students' understanding of epigenetics, focusing on their scientific representations from a chemical perspective. The purpose was to identify common misconceptions and assess how technological interventions can enhance students' conceptual models of epigenetics. A mixed-methods approach was employed, incorporating…

Understanding the relationship between protein structure and function can be challenging for students. Molecular visualization software aids students in this problem by allowing manipulation of structures from new and deeper perspectives. In this communication, an activity using iMolview Lite, structure visualization software for portable devices,…

This paper analyses students' conceptual sense-making of two representations of protein synthesis: animations and static visualizations. Even though several studies have focused on the effect of animations versus static visualizations or support aspects that enable students to effectively benefit from animations, existing research has not yet…

Computational techniques have great potential to improve the teaching-learning. In this work, we used a computational strategy to visualize three-dimensional (3D) structures of proteins and DNA and help the student to comprehend biochemistry concepts such as protein structure and function, substrate, and inhibitors as well as DNA structural…

We have developed a metabolic pathways visualization skill test (MPVST) to gain greater insight into our students' abilities to comprehend the visual information presented in metabolic pathways diagrams. The test is able to discriminate students' visualization ability with respect to six specific visualization skills that we identified as key to…
