1. Tipos de Problemas que Provocan la Generación de Argumentos Inductivos, Abductivos y Deductivos
Abstract This paper presents a relation between the types of conjecturing open problems in geometry, preferably solved using Dynamic Geometry Systems, and the types of arguments produced. The aim of this paper is to show how each type of problem can elicit the production of certain types of arguments (inductive, abductive, and deductive) during the problem-s

2. Microhardness and EBSD microstructure mapping in partially-pressed al and cu through 90º ECAP die
Equal-channel angular pressing (ECAP) is widely recognized as an effective method for processing ultrafine-grained and even nanostructured materials. Important details on processes occurring in the die intersections can be obtained by mapping the microhardness and EBSD microstructures in partially-pressed aluminum and copper through the 90º die of ECAP. Pre

3. As construções geométricas e a gênese instrumental: o caso da mediatriz
This thesis deals with the Instrumental Genesis, which is the preparation process of instrument by the subject. Studies on national and international levels have addressed this process, however, no studies that dealt with Instrumental Genesis referring to an abstract artifact were found. This research revealed the bisector as an abstract artifact. Thus, the

4. Situações de aprendizagem: a circunferência, a mediatriz e uma abordagem com o Geogebra
The research reported here describes a qualitative research, which was based in the Theory of Didactic Situations and in assumptions concerning the use of teaching strategies mediated by technologies in geometry. The didactic sequence proposed in this study aims to enable the participants, students in ninth grade of elementary school and first year of high s

5. Construções geométricas: uma alternativa para desenvolver conhecimentos acerca da demonstração em uma formação continuada
The purpose of this study is to analyze a sequence of activities carried out with in service teachers, aiming the construction of the definition of line bisector of a segment and, from this definition, to allow them to demonstrate inherent properties of this mathematical object. Moreover, the study also aimed that the teachers were able to justify it mathema

6. Proposta de um plano cefalométrico na avaliação da relação ântero-posterior entre a maxila e a mandíbula / cephalometric plane proposal in the anteroposterior jaw relationship assessment
The most published methods, for the anteroposterior jaw relationship appraisal, have got consideration. Some of them used cephalometric points in the anatomical structures far from the evaluated area (ANB angle), others as the Wits appraisal got instability and alteration of the occlusal plane and some others like MMº Bisector plane and ProjUSP evaluation u
