I’m at Disney World with CJ, on a Pirates of the Caribbean-style ride, a car careening through a tunnel. On the wall of the tunnel there are math posters, the kind you’d see in a high school classroom, about Pascal’s triangle, conic sections, etc. And I feel sort of annoyed and depressed, because I know that Disney is going to make a big deal about how educational this ride is, but actually, nobody except me is looking at the posters, nobody who didn’t already know the math could get anything out of the posters, the way the car speeds down the track.
Please interpret and derive relevant policy prescriptions for math pedagogy in comments.
