In this study, we have synthesized the research on visualization and representation to propose a model consisting of 4 major components of visualization competence in learning science: constructing, interpreting, transforming, and critiquing visualizations. We have developed and validated an assessment that measures students' visualization…

Background: A teaching method to improve students' ability to communicate ideas in genetics across the macro-micro levels of organisation was investigated in this study. Purpose: It is designed to help students deconstruct the level of organisation of each tier of a genetic diagram, as the symbols used in such diagrams (i.e. lines and letters) can…

Thermal cameras offer real-time visual access to otherwise invisible thermal phenomena, which are conceptually demanding for learners during traditional teaching. We present three studies of students' conduction of laboratory activities that employ thermal cameras to teach challenging thermal concepts in grades 4, 7 and 10-12. Visualization of…

Following up on the effects of learning environments is essential to learning. The aim of this study was to examine students' mental models related to the concepts of expansion and contraction of materials. The population of the case study consisted of 155 students in a city center in Turkey. The data was gathered using open-ended questions that…
