Abstract Title: Learning Progression of Mental Models on Conductor and Dielectric
Abstract: We classified students' mental models on conductor and dielectric into four levels: non-model, non-scientific, flawed-scientific, and scientific, varying progressively from naïve views to scientifically acceptable views. A total of 137 Chinese students from an introductory physics class completed a questionnaire. For the questions on conductor, about 20% of the students were at the non-model level, and almost 15% of the students constructed a non-scientific model and believed that both electrons and protons could move in a conductor. Those with a flawed-scientific model (35%) were unsure about the motion of the particles. Only 30% of the students had a scientific model. For the dielectric questions, over 30% of the students were in the non-model level; about 55% of the students had a non-scientific model and thought that charges could not move in a dielectric. The remaining 10% of the students used a flawed-scientific model. Implications of these outcomes are discussed.
