When I was supply teaching I covered art often - Most of the schools I went in classes consisted of a splattered butler sink in the corner with powder paints and then pencils and paper for drawing maybe some charcoal but not much else. The classes often were poorly attended with half the kids not bothering and the ones that did often not really doing anything chatting staring out the window.I only ever visited two schools where they had Macs and Photoshop.
