I also find that, converse to what happens in math or language arts, the
brightest students take the longest to finish a project, lingering longer
that their more impulsive peers. What do you do with those kids that are
done early, and adamantly refuse to workany longer? They often get into
difficulty with peers. This problem is particularly difficult for "art on
the cart" teachers who are guests in another teacher's room. How do you
push one group to finish while keeping the other occupied?
These are the things we were never taught in pre-service programs!
