What does it mean to be a "highly qualified" math teacher? Is that different from an "effective" math teacher? If you had to choose one or the other--and no, you shouldn't have to, but play along--which would you choose?
Dr. P over at EduInsights has two interesting posts on the subject. He essentially says that the states' standards for math teachers are entirely too low, yet also says that there's no research showing any correlation between teacher math knowledge and student achievement. That doesn't mean that a correlation doesn't exist, merely that there's no research proving one. So absent that research, how can he say that passing scores on teacher math tests are too low? That's just one small inconsistency that caught my eye in two otherwise very interesting posts, here and here.
