Explores the effects of Roundhouse diagram construction on a previously low-performing middle school science student's struggles to understand abstract science concepts and principles. Based on a metacognition-based visual learning model, aims to elucidate the process by which Roundhouse diagramming helps learners bootstrap their current…

Explores high school students' and preservice teachers' knowledge of light, vision, and related topics before and after commonly practiced instruction.
