Oh come on, this isn’t Pedagogy of the Oppressed, it’s a blog post of “things I didn’t understand until my first year on the job”.
TFA is a great post! It’s particularly interesting to laymen, and maybe rookie post-secondary faculty who have been taught a lot about their subject and very little (if anything) about how to teach. But none of it’s novel for anyone who’s been on the other side of the desk.
Talking about education practice in public forums is hard because everyone has a stake, and everyone thinks their experience as a student or parent plus a little common sense makes them an expert. Again, see literally any HN thread about education. TFA does a great job of reminding laymen that often those Chesterton fences are there for a reason. But sorry, I don’t think it’s a rejection of the idea of “sharing knowledge in general” to say that “visionaries attempting to restructure education” probably shouldn’t be laymen.
So, okay, “on the contrary” in my OP was a little strong. Not that anyone shouldn’t read it. But just because something is new to you doesn’t actually make it new.
