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.

I have already given credit to your know-how in this domain in another comment. You would be 99th percentile in knowledge, passion and experience compared to others around here. But maybe there are few ideas from the article we wished implemented in all schools. The author comes from a place of good intention.

Sustained initiative from people like yourself, backed by policy and support from the government can do wonders. And I and most people in this thread are grateful for what you do on the ground level already.

Or maybe they actually do have the experience and are sick and tired of people trotting out trite advice which is at best ignored and at worst draws attention away from the real issues by focusing people on useless advice which can be used as another stick to bash those less fortunate with.

Sometimes abrasiveness is warranted.
