摘要：Normal 0 21 false false false PT-BR X-NONE X-NONE MicrosoftInternetExplorer4 We have adopted Fávero’s psycho-pedagogic intervention research (2001ª, 2005ª) focusing on fractional numbers, rational numbers, and meditational competencies. We worked with an elementary school student and undergraduate mathematics and education students in intervention sessions, articulating: the evaluation of competencies and difficulties, planning and evaluation of the nature of mediations, and actions and notations. Psycho-pedagogic intervention engendered the construction of concepts and the awareness of mediation practices. We discuss its relevance in the understanding of mediation and notation, and its implications in elementary education mathematics and evaluation; the curricular guidelines for mathematics and education teacher training undergraduate courses; and research in the context of teacher training.
