Teach statistics: Arthur Benjamin argues that there is a fundamental re-orientation necessary in the way we teach math. Currently, the classes students take through middle and high school are like a ladder, each one building on the previous, with the ultimate apex being calculus (“the laws of nature are written in the language of calculus”). But for today’s world, what should be at that apex is statistics. Calculus is essential to certain branches of engineering and science, but statistics would be helpful in understanding our information culture for the average person on a day-to-day basis — a society would be improved by having a citizenship that is comfortable with the language of statistics. I love this idea.
