listelement.badge.dso-typeItem, Uma análise do ensino de proporcionalidade no ensino fundamental : realidade e perspectivas(Universidade Federal de São Carlos, 2015-11-23) Silva, Davidson Moura Lopes; Barros, Tomas Edson; https://lattes.cnpq.br/5442017085057925; https://lattes.cnpq.br/4153671674322010This work presents a new proposal of approach for proporcionality, whose focus is the Brazilian Elementary 7th grade student. This work is the record of a work of didactic engineeering that generated a sequence made by four didactic sessions. The main goal of this dissertation is to present ways for the student to determine, based on mathematical de_nitions, if two magnitudes are proportional and, in a_rmative case, if the relation is directly or inversely proportional. In order to do so, we propose the employment of a software called Geogebra as a teaching tool, to allow the integration with geometry, direct and inverse proportionality relations and practical experiments to assign a greater meaning to the presented content.
