I know there have been many request for survey type information about how
many classes, how long, how many kids per class, etc. Well Crayola did one
and it's published in "The Journal of the National Education Association"
Nov. 1999 , Volume 52, No. 6, $9.00 if you don't get the magazine. There a
also an article on Linking Brain Research to Art. No e-mail address so good
luck! Maybe another teacher has it. Gail
