Gestures play a key role for physicists and physics students in representing physics entities, processes, and systems. One affordance of gesture is the ability to laminate or layer together representations of concrete physical features (e.g., objects and their interactions) and symbolic representations (e.g., coordinate systems) to make sense of and model physical scenarios. Using interaction analysis, we illustrate how students can laminate these different layers of abstraction together in gesture to generate complex explanations to solve physics problems. We argue that laminating different layers of abstraction (both the symbolic and concrete) constitute a key form of representational competence in physics.
