In mathematics education the specific objective is to understand the way children build up their mathematical reality and the operations by means of which they try to move within that reality. The scientific investigators who enter this still largely uncharted field cannot search for some ultimate truth but must strive to understand individual children’s understanding. The way to do this is to embed oneself as best one can in the actual situations where children manifest their constructing and solving procedures. First-hand observation, not only of children’s mathematical activity, but also of how that activity can be influenced, is necessary to gain the experiential basis for formulating explanations of it. The researcher must actually teach children (Steffe & Cobb, 1983).","highlights":Ӷ^"jQuery3210446846850196055742":^°°,^"jQuery3210446846850196055742":^°°Ӻ,"text":"","order":"mw-content-text","category":"WissenschaftlicheReferenz2","data_creacio":1560247658284°
