Item Pequeno construtor: cenário de investigação para o estudo da geometria(Universidade Federal de Goiás, 2009-10-16) BOMTEMPO, Kênia; BARRETO, Maria de Fátima Teixeira; http://lattes.cnpq.br/1434730073194299This work investigates the possibilities of building miniature houses are scenarios for research for the study of geometry. It has made through a Master Programme of Education in Sciences and Mathematics at Federal university of Goiás. The study of geometry through the trial is a form of education defended by Education many researchers in mathematics education (ANDRADE; NACARATO, 2008; FAINGUELERNT, 1999; PAULO, 2001; PAVANELLO, 2007). Begin of a proposal to work through scenarios for mathematics research as it considers the student's participation in an investigative approach, through play and through the act of playing. Developed the project "Small Builder" in which students built mini-houses that the process of building geometric concepts we studied. The activities were developed in the Escola Municipal Santa Helena , at Goiania, in a room with 27 children between 10 and 12 years. The data were analyzed following the paths of qualitative research in a phenomenological approach. In the investigative process, we analyzed the ways of understanding expressed by the students and the educational intervention carried out by the teachers involved. The study converged to open three categories: the understandings expressed on the measures proposed scenario, the understandings expressed on ways and plane figures in the proposed scenario, the understandings expressed in addition to the geometry in the proposed scenario. These categories have shown the possibility of the project "Small Builder" is set as the for research, by enabling the study of geometry and also go beyond. The analysis showed the weaknesses of the teacher and student, and the ephemerality of the scenarios for research, allowing one to rethink the life-world classroom geometry.Item Superfícies Mínimas em H3 e H2 x R(Universidade Federal de Goiás, 2008-02-20) RUYS, Wesley da Silva; CORRO, Armando Mauro Vasquez; http://lattes.cnpq.br/4498595305431615In this work we study some results from the article of Mercuri, F., Piu, P., Montaldo, S; Weierstrass Representation Formula for Minimal Surfaces in H3 and H2 x R. Therefore, we do a study of the minimal surfaces simply connected in three-dimensional Riemaniann manifold. Furthermore, searching for to determine the necessary conditions to find minimal surfaces in these spaces. Moreover, to give examples of the surfaces in the three-dimensional Heisenberg group and in the product of the hyperbolic with the real line.
