Item Acesso aberto (Open Access) Geometria analítica plana: praxeologias matemáticas no ensino médio(Universidade Federal do Pará, 2007-05-07) ANDRADE, Roberto Carlos Dantas; GUERRA, Renato Borges; http://lattes.cnpq.br/3199659904537033This paper aims the construction and application of a didactic organization to the plane analytic geometry, based on studies about vectors, in the third grade of “Ensino Médio”, on the basis of the anthropology theory of Yves Chevallard and the significant learning theory of David Ausubel. This document has a quality nature and it is a kind of ethnographic in education, according to Marli André, and it was developed with a group of students in a specific context – the “Vestibular” preparation. The ostensible objects manipulation to the comprehension of no ostensible objects in mathematics was a category to the analysis of “praxeologias” in the classroom. We concluded that students manipulating ostensible objects rescue mathematics knowledge in an articulated and integrated form in order to get new math knowledge. It was also observed that the didactic organization allows “time saving” to this content study in this school life stage.
