Barras of the BBC in the "Future Education column" this month has a select, light-weight, informal summary of research and opinion on the impact of systematic, body-assisted learning, entitled, "Want to learn quicker? Use your body!" Although the studies referenced have been reported on the blog previously, that is still a readable, almost fun piece, one you can pass on to those new to the idea of kinaesthetic and haptic engagement. Especially like this quote from Cook at the University of Iowa:
"In every study that we’ve tested the importance of gesturing, we’ve found it works,” she says. “Even in the experimental settings where we thought gesturing wouldn’t work.”
I'd paraphrase that this way: In every aspect of pronunciation or teaching context that we've tried "haptic," we've found it works!
So will you.
(Have not formally tried the depicted "inter-nasal" gesture, but who nose?)
