Why is it important to teach that mathematics is a growing body of
knowledge? I mean, it's certainly true, and it is better to
be aware of the wide world than not -- but how much attention should be
paid to this in an 8th grade math class?

Oh sure, one wants the NSF to get funding, etc., so people need to be
wordly enough to recognize the existence of researchers. Then, too, as
a mathematician, I would like to see more people develop the
world-view of mathematicians and apply the general principles of
abstraction and reason to every aspect of their lives (though even
many mathematicians do a poor job of this -- for example, some think
their internal proofs of their own political prejudices somehow carry
as much weight as the proofs they produce in more appropriate
contexts). But what does this have to do with changing the curriculum
to reflect all the new math developed since WWII?

The bulk of the mathematics students learn in K-12 dates from the 18th
century or earlier. It is dressed up in 20th century notation, and
takes some of its emphases from the late 19th/early 20th century --
and is frequently applied to modern contexts -- but there is little
"modern" mathematics in it. Perhaps a few topics in the BC calculus
saw their first rigorous proofs in the 19th century -- not that the BC
calculus students are given complete proofs.

One could do quite well (at least as far as mathematics content is
concerned) with textbooks well over a century old. US Math Olympiad
students know, for instance, that Hall and Knight's "Algebra"
(it may be called "Higher Algebra" -- I don't have it in front of me), an
English textbook dating from the 1880s, aimed at preparing students
for University entrance exams, is an INCREDIBLE encyclopedia of useful
concepts and tricks.

Clearly one wants to give students a sense of modern applications.
But the essential core of mathematics is actually pretty ancient.
(That doesn't need to be so horrible, does it? Isn't there a thrill
in being part of an ancient tradition, imparting the distilled wisdom
of generations long past to the next generation? Is there no romance
at all in seeing a child wrestle with a concept the Greeks wrestled
with over two millenia ago?)
