Education majors have the lowest SAT, ACT, and GRE scores on campus.
I conclude that too many government teachers are:
1) Math phobics themselves.
2) Don’t have a high enough IQ to master math.
3) Were government school graduates themselves.
Also, the parents of school kids are, for the most part, were recently government schooled in “new” math methods, and therefore completely unable to teach their kids basic math.
When I was in college (late 60s), my university had a “School of Education”. The inhabitants were the utter dregs of academic society. Judging from what I read, nothing has changed.
