Anti-Constructivists?

[Michael Atherton]

I work in a university environment dominated
by constructivists.  I have been trying to find authors
or researchers who are publishing views contrary to
the NCTM standards...without much luck.  Can any
one tell me who are the national figures with views
opposed to the constructivist approach to mathematics
education?

Thanks.
