Abstract Title: Student understanding of principles of superposition in introductory calculus-based electricity and magnetism
Abstract: For the past two years we have collected data from thirty sections of our introductory calculus-based electricity and magnetism course taught in a studio setting. We sought to understand student thinking, establish the effect of Tutorials in Introductory Physics on student learning, and create additional instructional supplements intended to be used during group work. We administered weekly assessments requiring explanations of reasoning to give us a representation of their model. We examined student responses to questions on superposition of contributions to the electric field, electric potential, and potential energy from discrete and continuous charge distributions. Also, students took the Brief Electricity and Magnetism Assessment (BEMA) before and after the course so that we could evaluate growth in specific subdomains. Since superposition is not well represented in BEMA, we compared student performance on our written assessments with BEMA scores and subscores. Results of our investigations will be presented and implications discussed.
