Abstract：After analyzing the basic hypothesis, main contents and the explanation for children domain development in "RR model", this paper shows that actually the model is to replace Piaget's stage (or structure) theory with equilibration as its explaining mechanism. But can "RR model" constitute a replacement or rebellion to Piaget's theory? Actually there are amazing similarities (at least implicit) between this model and Piaget's explaining theory. "RR model" is but expressed in modern "information processing" language, whose gist is from implicit program to explicit knowledge and gist of "grasp of consciousness" theory is transferring exterior action into (conscious) conceptualization, or conscious awareness to the result, purpose and mechanism of action.
