the teacher prior to me used kistler's books and videos as her 6, 7, and 8th grade drawing lessons. she also used them to teach perspective and value. when i began to teach here i was so appaled that this was how art was being taught that i totally dismissed them as being of any value. i have the books and videos and never used them. are they appropriate at all for middle school? if so, if anyone is using them and can give me some advice, i may dig them out!
