Perhaps it was too abrasive.
Hubris? No, I don't have any amount of confidence to drive me to offer big, system-wide solutions. Because schooling and its issues are incredibly complicated and bring into play much, much more than just what happens inside the walls of a school building. One trivial example: students in Title I schools (read: poverty) have much higher rates of chronic health conditions. That's not really an issue in our wheelhouse, as a school, and yet we very much have to deal with it continuously. Pretty much everything in a student's environment, including their past, affects school, since school is where they spend most of their day. Yet people think you can just ignore all that and focus on teaching specific content or skills. Like kids are, academically, brains in vats, untouched by environment or circumstance.
