Directed or Random? Student Reasoning About Diffusion Across Physiological Contexts
Abstract
BACKGROUNDRandom molecular motion underlies diffusion, chemical reactions, and gas exchange, yet many students explain diffusion primarily as particles moving "from high to low concentration."Rather than treating this as a misconception, we adopt a dynamic systems perspective informed by Knowledge-in-Pieces and Resources frameworks to examine how students coordinate knowledge resources when reasoning about diffusion.
