You went through some kind of Math War and now feel relieved that the
Mathlands of the world have been beaten back. Your son was falling
behind. New New Math was the enemy more than New Math, which had already
gone down.

Hey, I can empathize. My late wife went to Florida State and although
enjoying calculus in Satellite Beach (next to NASA) was told women don't do
well at math and was discouraged from that major, reminds me of my current
housemate, also a Florida refugee. Population genetics was her next
greatest love.

My wife was alarmed by the walking-distance school's lackadaisical math
teaching; the all-subjects elementary teacher seemed afraid of it, a
contagious attitude.

Portland, with its "magnet schools" system had its Hogwarts for Geeks, also
public, and we moved our daughter there. A decade later, she's a physics
major, has looked ahead at diffy-Q and doesn't think it'll present a
problem, although carrying German and some other stuff was a big load this
semester.

She'll pull back a bit, knowing her limits, plus pick up RA duties.

As for myself, I escaped the USA orbit almost entirely in my youth. My
Overseas School of Rome was full of avant garde refugees, mostly teaching
counter to what they saw as uber-stultifying back home. Before that, I
went to a full blown school for Brits-in-training, wore a blazer/tie and
everything. I finished high school in Manila, taught mostly by Asians, and
thinking in an Asian way (which doesn't make me Asian according to those
going by eye shape (part of the baggage we don't inherit is all that crap
about races, not my idea and never a good one).

So is it true that SAT9's parent ETS was sold to the UK-based Pearson?
Just catching up.

I thought I was doing the opposite: showing how "scouting" could fill out
the "shop" side (so-called vocational) to where we covered all standard
math topics and then some. 3D printers make Polyhedra. V + F == E + 2.
Spherical trig part of everyday testing. Might do some slide rule, along
with abacus. None of this is "math class" though, as School B has decided
STEM is sufficiently subdividing (we slice it differently, don't use your
labels). As long as we connect all the dots School A does (A for Average),
we'll be Better ("we" might be AFSC **).

Unknown. I think background in rocketry and motor repair is already what
goes on applications for admission to such places i.e. a well rounded skill
set is considered a good hand. Say your rocket group got a projectile all
the way to 50% less atmosphere and was able to aim and gain exposures of
tiny astronomical objects while in flight. That's what the big boy and
girl astronomers do today with their modified 747. I think an HR person
checking a resume would necessarily draw a frowny face.

Some schools such as Haverford emphasize community service and values, such
that it's not considered OK to use your liberal arts advantages to make the
world an uglier place. If we make seeing the night sky without light
pollution, for all able-eyed, a requirement for graduation, then we've
shifted the culture.

Portland already has this. It's called Outdoor School, it's publicly
funded, and you need to do it in sixth grade. We have giant camps around
the city and lots of rotation. For some other cities in North America,
it'd be a radical change in everything to mandate such an operation, but
here they've yet to take it away. Nor have we let them fluoridate our
water (makes 'em stupid in Peoria).

I would fully approve of a math class that covered the basics of chess with
an eye towards using XY grids to display object motions, skills feeding
later programming with physics engines. Card games are also taught, along
with Tower of Hanoi and fun with Pascal's Triangle. The four operations
(Algorithms of Al Khwarizmi) get taught as games as well, rule-following
symbol-using.

We read excerpts from Godel Escher Bach and encourage each student
cultivating a set of favorite authors and book reporting on their merits,
text books and video series included.

Stand in front of the class and tell us what you liked and didn't like
about 'Who is Fourier?' (also on our syllabus).

Another thing about Portland as we don't have much Boston envy. I know
there's this East Coast mystique about Massachusetts, and in Oregon we're
supposed to feel inferior. That's partly because higher ed (academia)
likes to distinguish itself from industry, but if you factor in both
together, our Silicon Forest is as much a STEM capital as any
Atlantic-facing capital or capital-wannabe.

community service credit for some public school goers in Portland -- 120
hours of community service required).
