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…

Background and Purpose: Metavisualization plays a key role in science and technological learning in which visualization is practiced. We conducted two sequential studies with the purposes to first develop an instrument that allows individuals to report or reflect on their metavisualization, and then validate the instrument and investigate the…

Molecular modeling can be used as an excellent teaching method for providing better insight into the mechanism of free radical reactions. Due to its highly visual nature, it can affect and improve students' perception and visualization of chemistry phenomena. The majority of chemistry students will know how to represent a reaction between two free…

Background: Photomicrographs are major biological representations which help students understand more about the structures of cells and tissues. Owing to their abstract nature, students often rely on representations in textbooks to develop their understanding of photomicrographs. Purpose: This study investigated how students with low, medium and…

This study aims to use problem solving techniques in solving problems at different stages step by step. The theoretical and experimental semiotic model was developed by using the semiotic model method, which can be established with the relation of priority-recency, and an analysis of the problem solving skills of the students was made. Given that…

Calls for renewal of physics education include more varied learning activities and increased focus on qualitative understanding and history and philosophy of science (HPS) aspects. We have studied an innovative approach implementing such features in quantum physics in traditional upper secondary physics classrooms in Norway. Data consists of 11…
