This study investigates undergraduate STEM students' interpretation of quantities and quantitative relationships on graphical representations in biology (population growth) and chemistry (titration) contexts. Interviews (n = 15) were conducted to explore the interplay between students' covariational reasoning skills and their use of disciplinary…

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…

The aim of this study is to examine the concept images of mathematics educators and pre-service elementary mathematics teachers regarding the relationships between the concepts of slope, rate of change and derivative. Four mathematics educators working in different state universities and responsible for Analysis courses, three pre-service…

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…

This article closely examines (a) the "representational" connotation which is often implicit in many analyses of the scientific knowledge which children have (or have not) acquired when they are asked to say or show what they know and (b) the still common-place presumption that recollections are akin to the extraction of ideas from a…

Project-based learning (PjBL) has been increasingly promoted and extended to online environments to enhance the quality of higher education. However, PjBL involves complex processes requiring higher-order thinking skills, which may pose challenges to many students especially in online settings with little prompt support from teachers. The problem…

Ray tracing is a computer graphics technique used to produce realistic visuals by physically simulating the behavior of light. Although this technique can be described straightforwardly, fully comprehending it might be challenging. It is typically taught in the classroom using the 2-D formats, such as paper or a blackboard. We propose using…

This article draws on examples of student interviews incorporating multiple modalities to explore the writing lives of students as part of a larger project focusing on participants' experiences of writing within and beyond the university. We explain this innovative, iterative research method combining multiple texts and maps, characterizing it as…

Science teachers use a large number of visual representations and models in science classes to guide students to understand complex phenomena and to learn to conduct scientific inquiry. Fluent formation and use of visual representation involves metavisualization, which is a process related to metacognition and visualization. However, what kinds of…

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…

Learning analytics (LA) dashboards are becoming increasingly available in various learning settings. However, teachers may face challenges in understanding and interpreting the data visualisations presented on those dashboards. In response to this, some LA researchers are incorporating visual cueing techniques, like data storytelling (DS), into LA…

In this study, how prospective chemistry teachers (PCTs) perceive precipitation and conceptualize precipitation reactions at the symbolic level was explored. Further, it was of interest to identify PCTs' visualization of the sub-microscopic level of precipitation reactions. The sample was drawn from the Chemistry Education Department at the…

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…

In this paper, we describe a dynamic-model as a strategy to teach DNA transcription and translation in an active way. This activity aims to provide learning beyond memorisation through the simulation of molecular processes, stimulating the elaboration of questions and hypotheses by students. The dynamic consists of four steps, starting with…
