It is known that differently than English, French etc, in Chinese, numbers names are much shorter, like nine nine for 99 probably instead of ninety nine and this is a facilitating factor for math learning. If I do not misunderstand David, you intend to the point that US math curriculum is focused much more on empirical rather than the abstract thinking. It seems that Davydov, just in the opposite, proposes a curriculum giving a prominent place to this latter and says that this learning by counting in later stages constitute an obstacle for the children. 2014-12-22 1:29 GMT+02:00 Ed Wall <ewall@umich.edu>: > David > > This is quite interesting.
