Hmmmm....an ye, with all this knowledge, China is stagnating in terms of its scientific progress. The industrial revolution didn't happen, cheap labour is so plentiful, and most industry is carbon copied from the west.
This from a country where some of the greatest minds in history developed key knowledge in mathematics, science, agriculture, astronomy...
One wonders if, in pushing to excel through rote learning, and never allowing a child to question authority, the mind of a young child develops without the capacity for creative thought?
One of my DCs has the most valuable of traits - the ability to put concepts together in new ways. to make connections and associations. To think creatively. I think that straight As are all very well, but the ability to conceptalise and develop ideas is far more valuable. Our world depends on people having new, out the box ideas.
To my mind, the chinese method described here is cruel and not conducive to developing the whole individual - eg social skills are probably more important in business than ever before. Creative, innovative thinking, the ability and desire to challenge authoity and the status quo and strike out on a new, untested path is what as made the western economies rise.
