Student Ideas about the Small Particle Model of Matter
What ideas do students have about small particles of matter? The Two Cups of Liquid task is intended to elicit preservice teachers’ CKT related to students’ ideas about the small particle model (SPM) for matter. The first part of the task asks preservice teachers to articulate their own understanding about why two cups containing different volumes of liquid might have the same mass, while the second examines how elementary students might respond.
