During one class assignment, I ask my students to come up with solutions for reducing the recidivism rates of juvenile offenders. I divide them into groups, hand out several yellow sticky pads to each group, and give them five minutes to write down any and every idea that comes to mind, no matter how foolish, how expensive, or how illegal. The point is not to judge ideas, but to generate them. At the end, my class often has more than a hundred ideas.
