My wife, who's mother was a teacher for 35 years, also teaches at community college. She considered teaching at public school because if you do that for a couple of years, they forgive your student loan debt. After a few education classes, she decided that there was no way she was going to do K-12. No way!
Between the ridiculous statements of instructors and the shaky 'science' behind their words, the future K-12 teachers' words and actions repelled her.
