"I always start my class with a coloring assignment using crayons to color three pages from a variety of coloring pages pinned to the wall. Pick 3. Color them densely, trying to get as much of the crayon on the paper as possible. Students find it frustrating because crayons are surprisingly hard to work with, but they usually have some fun doing it. Until...when the finished pages were pinned to the wall, all of the pages were colored just the way I assigned-- but all the joy was gone. Something went wrong. What was it? This: I told them to color hard in order to do it right. And go straight to using force-- thinking I was showing them a short-cut---- this took away the way of coloring they would have found on their own. By telling them just how to do it, I took the playing-around away, the gradual figuring out that brings something alive to this activity, makes it worth-while, and is transferable to other activities. I realize now the best results came when I gave no instructions except, "spend time on this assignment." That was 3 years ago. Why did it take me so long to figure this out?"
