Energy-interaction diagrams: Fostering resources for productive disciplinary engagement with energy

The use of graphical representations structures students' reasoning about a physical scenario or problem. Different graphical representations for energy in physical situations highlight different aspects of energy and therefore may represent and foster different conceptualizations of energy. One particular representation of energy dynamics in a physical system, the Energy-Interaction Diagram, embodies a Stores and Transfer model of energy. In this paper, I show how the Energy-Interaction Diagram can evoke productive resources for disciplinary engagement with energy.
