I think the "should" there is doing a lot of work. But I think it's my ideal, anyways.

Been thinking about this. I suppose what you say here is generally true. My difficulty with it is that it has generally not been true in my experience. I think classrooms are more like a fractal, and even when you siphon off, say, the top 25%, the same dynamics re-form themselves (or should).

Nice -- appreciate the info!

Nice to see the hospital demolition is underway. I hadn't seen any pictures of that before.

You don't think there's an analog on the other end? Take a group of struggling students who can't yet access the grade-level content at the pace at which it's being presented, but instead present them with a selected 70% of it, and there's a chance they'll learn it instead of learning very little?

I'm excited about it, yes.

Exactly!

Sounds very interesting! Will add it to my list.
