Of course, it is not news that US students perfom poorly in math and science. What is probably not understood is how US graduate education impacts this in a big way. How does this happen? Here are my conclusions.
The Short Summary: For a variety of reasons, graduate schools give Ph.D.’s to people that they know are not qualified for such a degree. These new Ph.D’s are not confident enough to teach math at any depth. Many of their students wind up being the k-12 teachers who don’t know math.
A more detialed explanation will appear later
