Abstract:

<p>Using multiple representations in physics instruction can help students to develop rich understandings. As part of the Raising Physics to the Surface project, we have developed an activity using geometric representations to help middle-division students understand the connection between changes in electric potential and the line integral of the associated electric field. Students work in groups with a dry-erasable 2-D vector field map and a corresponding potential surface. In this talk, we present examples of student reasoning from classroom video and discuss how the use of the tools support student learning and discussion.</p>
