Direct linkHung, Jung-Yi; Chang, Hsin-Yi; Hung, Jeng-Fung – Research in Science Education, 2021
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…

Chang, Hsin-Yi; Quintana, Chris; Krajcik, Joseph – Journal of Science Education and Technology, 2014
In this study, we investigated how students used a drawing tool to visualize their ideas of chemical reaction processes. We interviewed 30 students using thinking-aloud and retrospective methods and provided them with a drawing tool. We identified four types of connections the students made as they used the tool: drawing on existing knowledge,…
