I homeschooled my daughter in basic algebra. I was appalled that the teachers edition of the textbook gave the teacher scripts to read out loud for explaining concepts. So the “teacher” doesn’t actually have to know any algebra at all.
“So the “teacher” doesn’t actually have to know any algebra at all.”
It’s the same for every textbook. That’s how one elementary school teacher can teach Social Studies, English, and Math without actually having 3 degrees in different subjects.
But the problem arises when they actually get a “bright” student who asks insightful questions. Then the teacher can’t answer.
