The article seemed full of wishful thinking and bad ideas to me.
I taught algebra II to my son last year. It's a hard course. Well, it is if you are't teaching from a watered down book that leaves out trigonometry and proofs and sticks to A-type (means easy) problems with few B- and C-type problems (if any).
“[The inhabitants of Japan and Korea] do not need to read this book to find out that intelligence and intellectual accomplishment are highly malleable. Confucius set that matter straight twenty-five hundred years ago.”
But it's nice to know that Confucius was a neuroscientist, I suppose. Though you'd think the inhabitants of China would know that, too, rather than just the folks in Japan and Korea.
