A pesquisa de interven o psicopedagógica: evidências sobre o ensinar e aprender matemática = Psycho-pedagogic intervention research: evidence of mathematics teaching and learning

Adotamos a pesquisa de interven o psicopedagógica de Fávero (2001a, 2005a) focando os fracionários, os racionais e as competências mediacionais. Trabalhamos com uma estudante do ensino fundamental e graduandos em matemática e pedagogia, em sess es de interven o articulando: avalia o das competências e dificuldades, planejamento e avalia o da natureza das media es, a es e nota es.A interven o psicopedagógica engendrou a constru o de conceitos e a tomada de consciência das práticas mediacionais. Discutimos sua pertinência na compreens o da media o, da nota o e implica es para a matemática da educa o básica e avalia o; as Diretrizes Curriculares das licenciaturas em matemática e pedagogia;a pesquisa na forma o de professores.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.
