Abstract Title: Students’ Difficulties in Understanding The Explicative Model of DC simple circuits
Abstract: In the first years of university, results of PER show consistently that students don't relate electric circuit phenomena with the concepts studied previously in electrostatics. The present work focuses on students' explanations about stationary states in direct current (dc) electric circuits regarding elements of theoretical explicative models (Drude's model and Surface charge model). We inquiry about students' description at microscopic and macroscopic levels in terms of the electric field, electric potential and surfaces charges for explaining dc simple circuits. Some specific examples of the questions used to carry out the investigation will be discussed. The results will be used to develop further research on the ongoing investigation.
