>The average starving PhD would be a much better and more knowledgeable teacher to high school students in the subject she took her PhD in

i dont think this is true.

there is an art to educating (especially the ~10-15 year old range) that does not just manifest itself because you are smart: how to engage students, how to keep them engaged, how to adjust the message to the audience's level and communicate it effectively (which changes kid to kid), how to earn a kids respect without becoming over-bearing (or too friendly), and dozens of other things that your PhD in compsci or whatever does not teach you.

some of the smartest PhD holders i know would be very shitty elementary/high school teachers.

(context: i teach at the college level. its a lot easier than teaching at the high school level.)

Yeah there's some truth to this - I find that my Ed students don't always have sophisticated understandings of their content area (though honestly I find that ENGR and BIOL students don't, either). But they do get more content area teaching than in ED.

ED as a field is 100% all-in on AI, too, so there's a lot of discussion amongst them about what skills in the field need to be automated and what has to stay artisanal. But I'm sympathetic to zozbot's claims too - I do think the reading scores would be higher if there were more comp/rhet specialists in sec. ed.

Yes to this! What makes a great teacher is the willingness to hold kids accountable for their behavior and their work. Sure, it helps to be a subject expert, but that won't matter if you can't manage your classroom.

And parents play an equally important role. One of the best things you can do for your child's education/life is support the teacher when they call you up and say, "Your child is making poor decisions..."

~10-13 mostly comprises the junior high range. By the time the kids are 14, they're plenty old enough to benefit from a "college-prep" educational approach. Sure, some PhDs will be better, others will be worse. But you solve that by throwing out terrible teachers and rewarding the best ones. There's no guarantee that an Education-credentialed teacher with negligible education in the actual subject they're supposed to teach would be any better.
