Designing and evaluating a research-based Teaching sequence for electrical capacitance

Abstract

This presentation examines the didactic suitability of introducing a teaching sequence when teaching the concept of electrical capacitance in the context of charging a body. This short sequence targets first year university students and was designed following students’ common conceptions on this topic. The evaluation is made by comparing the results with a control group using written questionnaires. The results show that the elements within the sequence help students to establish a connection between the movement of charges (micro frame) and the energetic analysis of the system (macro frame).
