I taught science at a charter school for a half year... Anyone on this site, is more than capable of home schooling their kids.
High school level chemistry and biology, dumbed down to a 4th grade reading level is a fuckin useless waste of time. The 'school' did base 50 grading, so i couldn't even fail the little shits for not getting any of it.
We're fucked as a society; educators aren't grading for mastery, or to assess if the students have EARNED a high school diploma. It's taken as a given they need it, and are going to get it.
I taught some college level classes for a little while. I gave up on it. I had students that couldn't even use "CTRL+F" to search a webpage to find answers....
