Rudbeckia Hirta on teacher education

from the comments thread to Singapore Math in Israel:

My understanding is that under NCLB that people who want to become teachers need to major in an academic discipline (an "arts and sciences" field -- not business or architecture or some other professional field). Their education training is typically a minor in education followed by a "professional year" in which they do coursework as well as their student teaching / internship.

Thus, a future teacher's math courses are determined by his or her undergraduate major. If someone majors in chemistry in preparation for becoming a high school science teacher, then he or she will have taken calculus and more from the math department.

However, if a potential elementary school teacher chooses to major in psychology (one of the most common majors at my institution) or English or some other field that is not particularly quantitative at the undergraduate level, then the only math that he or she might take would be the intro-level gen-ed courses required for the bachelor's degree. These courses are often taught by the lowest rank instructors in the math department.

At some universities, the pre-service elemenary school teachers are funneled into a "math for elementary ed" course. Depending on the university, this might be taught by either the math department or by the education department. At my own institution, for many years it was primarily taught by an education grad student.

I have also taught this course. The experience made it clear to me that many of the people who wish to teach elementary school do not have the necessary math background to do an excellent job at it unless they have a lot of support and well-written instructor's guides.

I'll repeat my question here.

"Math dad" tells me that in the state of NY all teachers 6-12 must have majors in liberal arts disciplines.

Are there special math majors for people planning to go into teaching?

I remember a few years back I was thinking about becoming a science teacher in the middle grades. I'm a science writer; I figured I can teach science.

It turned out that I would have to go back to college for a full major in a science. I remember figuring that if I took one course each semester and in the summer I would be certified by the age of 60, at which time I would become the most employable 60 year old on the planet.

I met with the head of the Science Education program at NYU who told me that this requirement was going to be impossible to meet, and that she anticipated colleges & universities would create special science majors for future teachers.
