I agree intellectually, but still find this amazing, and a bit guilty, emotionally: a proficient “teacher rarely finishes any of the cognitive work that students could own.” -Wow. In other words, the students not only should think critically, not only ought to be encouraged to think, but must think critically, and for themselves! This is what school should have always been! This is not the teacher who asks, waits half a second, and then answers her own question while the students sit and look at her: this is pushing kids to use that gray matter between their ears as if they really were real people -and they are!
(Yes, I am hearing the theme song of “Kids are People, Too!” from way back when!!)
