while looking up info about this, I found this very interesting article about Japanese teaching methods.
http://www.japantimes.co.jp/community/2014/11/23/issues/teaching-quality-lesson-quantity-may-key-japans-top-math-marks/#.VlKbjCvCdywBasically, Japanese schools perform way better than many western ones in mathematics in the PISA test of 15 year olds. So, maybe they're spending a lot more class time on maths?
Students in Japan spend nearly 235 minutes a week learning math, according to Miki Tadakazu, an education analyst with the OECD, only about 20 minutes more than the OECD average.
Well, strike that theory then. Well, maybe they're spending all night in cram school then?
In PISA’s 2012 questionnaire, Japanese 15-year-olds reported spending an average of just over half an hour a week in a commercial after-school learning environment — read juku — which is in line with the OECD average. In fact, the Japanese polled came in below the OECD average in time spent on all other forms of after-school work, whether it was teacher-set homework or study assisted by a home tutor, family member or computer.
Yeah, for all the vaunted "cram schools" it's actually less time spent doing homework than the West.
So, what's the difference. Perhaps they're really, really into rote learning. That's the other theory you heard bandied around: asians just have a thing where they soak up all this knowledge delivered in the least engaging way possible and score higher than westerners because they're just super study machines.
Unfortunately, if you read the article, the western method sounds more like rote learning compare to the Japanese method. The western model of maths teaching is that the teacher writes the solution up on the board for a sample problem, the students write this down, then you individually solve additional problems using the provided solution. After that, you're given homework where you repeat the teacher's "one true method" of solving the problem over and over again. Now,
that's how you rote-learn a maths formula.
Whereas the typical Japanese maths class is described in the article. The teacher gives the children an unknown problem. The teacher then gets the children to try and solve it. When one does, they get their work checked by the teacher. After that. they can stand up, move around and help other students. So it morphs into ad-hoc study groups where the quick students help the others. After that, it morphs again into a class discussion of the problem and the various ideas students came up with to solve the problem. Yeah, sounds like just about the opposite of rote-learning to me ...
