Where AP teachers go to learn what they teach

Twenty-six high school teachers stood with straws in mouths and spoons at the ready. Bowls of M&Ms rainbowed before them. Pretend the M&Ms are fish, the instructor said, and pretend the straws are fishing poles.
The teachers sucked up the M&Ms with the straws. They scrapped for them with the spoons. As the candy disappeared, a lesson about regulation and natural resources took its place. This is what Advanced Placement teachers do when they step away from the front lines of an education revolution.  Ron Matus, St. Petersburg Times, June 21, 2009
