Because of the characters of children's cognition,we emphasis on connecting to the real world in school.What mainly children learn in school mainly are symbols.The knowledge had been inherited from ancestors and learning of it is very important.But knowledge represented by symbols is abstract and hard to understanding because it is divorced from its culture and contexts.If we don't teach it in special contexts,students would have difficulties in understanding how does this knowledge generate and how to use it.So,Dewey claimed that concept,skill and believe will be meaningful and useful only in contexts(Dewey,1938)[20].Besides,we find this teaching method have other advantages:children are glad to learn and they construct things by themselves.Children learn foreign language well in the contexts of using the language,which prove that contexts are very important to learning.We should note that we are not repeating Dewey's ideas.Learning of core concept in contexts absorbs the advantages of Dewey's and Bruner's theories.Its exact description is:if want valuable and meaningful learning happen,students must learn in a special context,even the content they learn is prescriptive,standard,appointed and determined by outside.
