Yeah, what I got out of that was basically that we REALLY need to teach elementary educators numeracy, quit excusing those who don't/won't learn it, and make sure that EVERY teacher in every classroom is actually competent with the math (er-- or probably anything else, really, it's just that math is a particular weakness for so many of them) that they are expecting students in those classrooms to be learning.
I can't say that I disagree, but I think we all have to be willing to look at the elephant in that room:
there are some teachers who really are not subject-competent in this area, and there are also some teachers who probably cannot be made so.
The old saw "Those that can't do, teach"? Um-- yeah. About that. Maybe this is part of the problem.
