I just heard about a study by a psych out of Berkeley on NPR today. She talked about babies and young kids being "lanterns" of learning. They see everything but don't focus well. OTOH, adults are spotlights: better able to focus, but that means excluding a lot from notice. She suggested that instead of saying that kids aren't good at paying attention, we should say they can't NOT pay attention! That made a lot of sense to me.
I think this sort of program ignores the way most babies and young kids learn. That's what is wrong with it. It's not about hothousing per se. It's about bad pedagogy.
IMHO...
