The issue is whether the testing, whether integral or not, is revealing the same information for the new way as for the old.
A teacher in the tank for handson approaches reporting how great the kids are doing isn't the same. The plural of anecdote is not objective data.

NO, Kirby. Shop at my school was for *everyone*, including the middle class white kids. The math in the shops was below grade level because shop in the 8th grade didn't (and doesn't) require much math.

Yes, they do. Do they call it math, or do they call it chess?
I recall in the college symphony that math, physics and engineering majors dominated the percussion and brass sections. We called it "music", not math, despite the mathematical relationships specified by the musical notations, yet another bit of technology that was developed over the last millennium.
Really, Kirby, let's call the spade a spade. Math isn't orienteering, chess, music or woodshop.
