This reminds me of an exercise a friend and I used when we were using our
noon hours to draw (not at school--neither of us was teaching at the time)
We were working with Betty Edwards and Nicolaides (The Natural Way to Draw)
.One would pose, the other draw. Then the "poser" would make a quick
drawing of the pose from "kinaesthetic memory". I've always felt these
memory drawings were some of the most valuable exercises we ever did.
When students want to know more about how to draw an action, I always have
them model the action first--both to discover the stage of the action they
want to draw and the positioning of body parts.--always wished I could have
had a mirror in the room for this purpose also. This would also have helped
them understand the effect of overlapping etc. in grouping for composition.
