This problem (criticism) was solved by Jeff Saul in his dissertation at the
University of Maryland. He repeated Hake's work in a 2000 student survey
that didn't rely on voluntary submission of test scores. Results were
similar to, but a little lower than, Hake's 6000 student survey, for both
traditional and for reform. Contact him at

"Hake's paper is the one to look at. His papers are
available at http://www.physics.indiana.edu/~hake/ and the one I think you
want is at http://www.physics.indiana.edu/~sdi/ajpv3i.pdf the results of the
6000 student survey. This survey has been criticized that it relied on
voluntary submission of test scores."
