O software régua e compasso como recurso metodológico para o ensino de geometria dinâmica

Abstract

This dissertation aims to investigate the use of software Ruler and Compass as a methodological resource for teaching geometry. The study was on theoretical base the Van Hielle‟s Model, the Meaningful Learning Theory (AUSUBEL, 2003) and the Construcionist Theory (PAPERT, 1994) linked to studies on the Dynamic Geometry (ZULATTO, 2002; GRAVINA, 1996, Cowper, 1994). The research was based on the difficulty of identifying and exploiting these properties in geometric patterns observed in static printed material such as textbooks. The research universe was formed for two public schools and one of these schools the research was conducted with students and in other school the research was conducted with teachers. The research involved a multiple case study using participant observation was conducted in two stages. The target audience of the research was formed by students of the 7th year of elementary school and teachers math of public schools. The results of the research show that there is an enormous need regarding the teaching of geometry founded on the manipulation of geometric figures to explore their properties and elements. The research also revealed that from the use of the software Ruler and Compass students have become more interactive and that during use they were challenged to conjecture, validate hypothesis and verify properties present in geometric figures. The study allowed us to observe that most of the teachers participating in the research are considered prepared for the use of new technologies in teaching mathematics, but that the school needs to adapt to such developments.
