Student Misapplication of a Gas‐like Model to Explain Particle Movement in Heated Solids: Implications for curriculum and instruction towards students’ creation and revision of accurate explanatory models (original) (raw)

International Journal of Science Education, 2009

Abstract

Understanding the particulate nature of matter (PNM) is vital for participating in many areas of science. We assessed 11 students’ atomic/molecular‐level explanations of real‐world phenomena after their participation in a modelling‐based PNM unit. All 11 students offered a scientifically acceptable model regarding atomic/molecular behaviour in non‐heated solids. Yet, 10 of 11 students expressed the view that, in response to added
