Drawing is a trans-disciplinary tool of thought and collaboration in teaching, learning and research. Drawing as a tool of thought leverages human cognition as both embodied and situated in the physical and environmental contexts in which it takes place. Drawing harnesses and integrates multiple capacities for perception, action and cognition. Visual and spatial metaphors play a prominent role in our everyday thoughts and speech. When we ask how to level the playing field or balance the scales of justice, we are using visuo-spatial metaphors to ground conceptual thought. Drawing allows us to play with these visuospatial metaphors. By slowing down in order to externalize ideas and perceptions on paper, drawing makes visible the fuzzy and iterative nature of much of human thought. We pay attention to that which otherwise might lurk beneath the surface of conscious awareness.
