1. Visualización y Razonamiento Configural
Abstract This research analyses the relationships between the identification of prototypical figures and geometrical knowledge in solving proof problems as a evidence of configural reasoning. We analyze the answers of 182 preservice teachers on two geometrical proof problems, which include a geometrical configuration and a request for proving a geometrical f

2. A desconstrução do esquema gráfico aplicado ao ensino de desenho para crianças cegas
The current dissertation is inserted in drawings teaching studies in the non visuality scope and presents a proposal of procedures elaborated from a group of drawings done by standard kids. For that, it started from the presuppose that blind children build graphic schemes after an education and drawings elements exercises, it means, lines and basic geometric

3. Um estudo sobre propriedades do paralelogramo envolvendo o processo de argumentação e prova
O presente trabalho, vinculado ao projeto AprovaME, desenvolvido na Pontifícia Universidade Católica de São Paulo, tem por objetivo verificar os avanços e as dificuldades apresentadas pelos alunos na elaboração de provas sobre as propriedades dos paralelogramos. Os procedimentos dessa pesquisa foram fundamentados nas teorias de Parzysz (2001) sobre pro

4. Argumentação e prova na matemática do ensino médio: progressões aritméticas e o uso de tecnologia
In the first term of 2005, I joined the Professional Masters degree on Mathematics Teaching at PUC/SP. In this same year, the research project AProvaME, whose goals are: investigating concepts about argumentation and proofs of teenager students at schools from São Paulo state; structuring groups composed by teachers and researchers in order to elaborate act

5. O papel da geometria descritiva nos problemas de geometria espacial; um estudo das secções de um cubo
Este trabalho tem por objetivo estudar um ramo da Geometria tão pouco comum no Ensino Médio: a Geometria Descritiva, em particular quando usada, em um ambiente da Geometria Dinâmica, para investigar o problema das secções de um cubo. Três idéias nortearam a busca dos fundamentos teóricos: os princípios do "visto" e "sabido" de Bernard Parzysz (1988a

6. Conceito de área: uma proposta de ensino-aprendizagem
The objective of the research is to study phenomena that influence the teaching and learning of the concept of area in Ensino Fundamental (students aged 7-15). It presents a teaching proposal for the concept of area and a reflection about the learning of this concept through a teaching sequence involving the decomposition and composition of plane figures. Th

7. DESENVOLVIMENTO DE SISTEMAS ESTRUTURAIS SEMI-RÍGIDOS EM AÇO E MISTOS PARA EDIFICAÇÕES RESIDENCIAIS MULTI-FAMILIARES / SEMI-RIGID COMPOSITE SYSTEMS FOR RESIDENTIAL BUILDINGS
Nowadays, despite the substantial increase in structural design knowledge, the semi-rigid connections steel design is still facing resistance from the structural engineers. This fact can be in part explained by few design standards that allows and explains their use, suitable computer programs and the lack of detailed information of the economical advantages

9. Star volumes of villi and intervillous pores in placentae from low and high altitude pregnancies.
Histological sections of placentae from pregnancies completed at low altitude (400 m) and high altitude (3600 m) in Bolivia were analysed using a stereological estimator of the star volumes of villous 'domains' and intervillous 'pores'. The purpose was to test whether or not differences in the overall volumes of these compartments are accompanied by changes
