1. Uso por Alumnos de Bachillerato de los Fenómenos Aproximación Simple Intuitiva y Retroalimentación en Sucesiones
We report the steps followed to set up an instrument oriented to detect two phenomena (intuitive simple approximation and feedback)in the answers given by high school students to questions concerning the finite limit of a sequence. We present our research's didactical and methodological frames. Along the field work described, we could collect answers from 14

2. Equações diofantinas lineares : uma proposta para o Ensino Médio
This work, whose methodology is inspired by didactical engineering, discusses and investigates the viability of introducing linear diophantine equations at High School level study and teaching. We developed and applied a didactical sequence to a first semester chemistry oriented high school at the Pelotas campus of the Sul-Rio-Grandense Federal Institute. We

3. Contrato didático : negociações, rupturas e renegociações a partir de uma sequência didática sobre progressão aritmética.
Esse estudo teve por objetivo investigar como uma professora negocia o contrato didático com alunos do 2 ano do Ensino Médio, na aplicação de uma sequência didática previamente elaborada para o ensino de Progressão Aritmética (P.A.). A sequência didática foi idealizada contemplando a tipologia das situações didáticas proposta por Brousseau (aç�

4. Uma abordagem histórico-filosófica na educação matemática : contribuições ao processo de aprendizagem de trigonometria no ensino médio
The aim of this research was the construction process of a historical-philosophical approach through a historical reconstruction of Trigonometry, in which we carried through a documental research on the basis of History of Mathematics textbooks, particularly those that deal with the History of Trigonometry. We used a qualitative methodological approach, in w

5. Equações diofantinas lineares: um desafio motivador para alunos do ensino médio
This work presents a qualitative study guided by the question Is it possible High School students to make explicit knowledge on linear diofantine equations? , whose relevance is justified from researches as met in Lopes Junior (2005), revealing that High School students do not distinguish and they do not understand when the variable assumes discrete or conti

6. Argumentação e prova no estudo de progressões aritméticas com o auxílio do Hot Potatoes
This research work deals with the theme Argumentation and Proof in the study of Arithmetic Progressions. Its purpose is to investigate the cognitive development of students in building concepts and knowledge related to the Numerical Sequence and Arithmetic Progression (AP), and in developing argumentation and proof-related competencies. Such purposes resulte

7. Produção de texto na sala de aula: encontros e desencontros com o Letra e Vida
To think about the contexts of the literacy teachers training in service is to assume, towards society, a political commitment to the educations quality and equity to all children who occupy the schools seats in the Governo do Estado de São Paulo education network. Thus, this research intends to verify how the theory and the methodology proposed by the Lite

8. O estudo do paralelismo no ensino da geometria analítica plana: do empírico ao dedutivo
This dissertation involves a study of argumentation and proof in relation to the teaching and learning of analytic geometry and particularly the property of parallelism in this topic. The work seeks answers to the following questions: in what form can dynamic geometry environments contribute in students attempts to construct mathematical arguments and proof?

9. O uso de material concreto com representaÃÃes retangulares na construÃÃo do conceito de decomposiÃÃo multiplicativa
This study aims to investigate the effects of using of manipulatives that explore rectangular representations of multiplication to appropriate the concept of multiplicative decomposition of natural numbers by 5th grade students of elementary school. The use of manipulatives was investigated on the basis of the theory of didactic situations, developed by Guy

10. From sequences of geometrical patterns to the introduction to algebraic thought / Das seqüências de padrões geométricos à introdução ao pensamento algébrico
The aim of this research is to study the introduction to the geometrical thought by means of sequences of geometrical patterns. Furthermore, we present an approach to pre-algebra in the elementary education and a discussion on the learning of such subject by means of a didactical series consisting of eight activities elaborated from the use of a series of ge

11. A distribuição binomial no ensino superior
By the evidence of binomial distribution of probabilities in Statistics and some known difficulties in teaching and learning process of Probability, we developed this work to learn more about some aspects of binomial distribution and its relation to other probability distributions, to trace a short view of performed researches about teaching and learning Pro

12. Seqüências numéricas: um estudo da convergência através de atividades
This study discribes research performed with the help of activities that place great emphasis upon the students actions. Teaching and learning the concepts connected with limits and infinite has proved a hard task, often with unsatisfactory results. In France, Aline Robert has done research with over 1.300 students on the acquisition of the concept of conver
