Abstract Title: Negotiating Novel Forms of Energy: “Phase Energy”
Abstract: Most definitions of forms of energy, including the national standards, suggest that forms are somehow associated with physical processes and properties of systems, but are silent on exactly how a form of energy relates to the physical state of a system.  Form is a useful shorthand label for describing the state of a system, which can enable efficient communication, but can also obscure meaning.  When a student uses a label for a form of energy, we do not know what meaning is packed inside that label.  We present video analysis of teachers studying energy in a summer professional development program.  By watching them grapple with a novel form of energy that is not included on standard lists of forms, we can better understand how they think about form in general.  Implicit in this process is an understanding of the meaning of form that goes above and beyond the standard.
