Kirby, everyone's kids were falling behind, everyone at the district was
in denial before the SAT9 was forced on them, and the New New Math is
still here. For example, Phil Daro, one of the architects of
California's whole math debacle is a prime mover of the Common Core
disaster apparently in the making.

New Math was great stuff, just inappropriate for most math teachers. One
can still buy the New Math inspired Dolciani Structure and Method
series, and they were a godsend when even the St.Sensible fell short of
my son's needs.

BTW, I'll cut the flogging of the dead horse to a minimum. I chose MIT
as the real STEM baccalaureate institution to refer to because the two
real STEM colleges that are ahead of MIT for the percentage of alums
with PhD's are both in Los Angeles County and I didn't want to trigger
any Ore-gone-ian Californiaphobia.

Most STEM cheerleaders are essentially just cargo cultists erecting poor
imitations of science, math, and engineering hoping that good STEM stuff
will drop in.
