While I ponder my next J.A.E.S. installation, I want to get a little bit political…
As an engineer, drawing to communicate concepts, and to record the current and proposed physical situation, was just as important as getting the calculations right, just as important as understanding the science, and just as important as understanding the technology. In many ways, drawing was the glue that held the other areas of expertise together. Being able to make good drawings, and diagrams, helped me win over others to my way of thinking.
Drawing is an absolutely essential CREATIVE skill across the curriculum.
Art in general and drawing specifically develops skills that must be taught, in fundamental form in art, and then expanded in context across all other STEAM subjects.
