"Dr. Richard Nisbett and his colleagues have found that people in different cultures think not just about different things, but think differently. "
This, of course, is a different idea from Gardner's (and I have previously expressed skepticism over Gardner's overbroad claims), but the point is the same--we cannot use the same ladle to spoon out "knowledge" (even if you do buy into this metaphor) to different students without regard for their background. At issue is the kind of background we are talking about.
Nisbett, of course, is no slouch in the field, so what he says will command attention in the cognitive science circles. The question I have to this list is whether we should and/or will pay attention to these developments?
