Considerações sobre o uso da linguagem na sala de aula de Matemática

The main goal of this work is to build a sketch on how language is used in mathematics classrooms. We specifically try to understand how teachers use language in order to share meanings with their students. We initially present our main intentions, summarizing some studies that are close to our purposes. The two theoretical frameworks which support our study – the Model of Semantic Fields and the Wittgensteinian “games of language” – are then presented and discussed about their similarities and distinctions. Our empirical data are some classroom activities recorded and turned into “clips”. Such clips were transcribed and our analysis was based on these transcriptions. Data analysis – developed according to our theoretical framework – allowed us to build the so-called “events” and, then, comment on some understandings on how language can be used in mathematics classrooms.

Escola técnicas agrícolas: um estudo sobre ensino de Matemática e formação de professores

The central focus of this paper is to establish that the Brazilian Education Programa to prepare professionals in Technical-Agricultural Schools is suffering a kind of marginalization which comes from two distinct perspectives: the intention to prepare professionals (being a branch of Technical Education) and the relationship to the countryside (a community space historically seen as peripheral in its relation to urban culture). The paper discusses – from a historical and sociological point of view and using Oral History as methodological approach – the experiences of Math’s teachers in their daily struggles against some conceptions of other teachers (mainly those of technical areas) and against all the “regular” schooling system.

Registrar oralidades, analisar narrativas: sobre pressupostos da História Oral em Educação Matemática

The discussion about some features of the general framework which allows the use of Oral History in Mathematics Education is the main theme of this paper. Also the conception about what Oral History is, its theoretical baskgrounds, some of its purposes and the range of its results to Math Education research community are considered, as well the link between such method and the narratives, focusing what narratives are and how narratives can be analysed. A brief description of specific themes and researches developed in such approach, in Brazil, ends this article.

História e ensino de Matemática: construção e uso de instrumentos de medida do século XVI

Entre as diversas iniciativas que procuram aproximar a História da Matemática do ensino da Matemática, o uso de fontes primárias tem sido muito promissor. Seguindo de perto esta tendência, propomos abaixo três atividades baseadas em excertos retirados de uma obra publicada no século XVI

Metodologia de projetos: uma possibilidade em sala de aula matemática

Neste trabalho, apresentamos resultados de uma oficina desenvolvida sob a perspectiva da metodologia de projetos na sala de aula de Matemática, num programa de formação continuada oferecido pela Secretaria de Educação do Estado de São Paulo Teia do Saber, na Universidade do Sagrado Coração USC Bauru SP. Por meio desta oficina, foi possível constatar a viabilidade desta metodologia, bem como a importância da formação continuada dos professores, principalmente por serem fornecidos dados de uma atividade bem sucedida, realizada por uma professora de Jaú interior de São Paulo. Nesta oportunidade, portanto, esboçamos nosso trabalho sobre a metodologia e destacamos a experiência da professora em sala de aula, tal como nos foi relatada.

História oral em educação matemática: contribuições para um referencial

The main intention of this paper is to present how a Research Group in Mathematics Education – known as GHOEM, “Oral History and Math Education” Research Group – is taking Oral History into account in Mathematics Education researches, sometimes challenging and expanding this specific methodological approach in order to better answer questions in Math Education field. The composition of such group, as frequently occurs in a research community, is dynamic. So, the works taken into consideration in this paper were those written by researchers which were GHOEM members at the time they published their results.

Sobre a identidade do Centro de Educação Matemática (CEM): acidentes de uma leitura cartesiana

In this paper we present results of research conducted on the constitution of the identity of CEM (Centre for Mathematics Education), a group of mathematics teacher educators from the city of São Paulo, Brazil (1984-1997). We emphasize the processes of constitution of CEM’s identities, on the perspective of Oral History in Mathematics Education, of the Model of Semantic Fields and of theories of identities. As part of the broader endeavor of examining possibilities for constituting identities for the group, from several theoretical standpoints, here we report an exercise on constituting the identity of CEM from a Cartesian standpoint; the overall assumption is that we are not properly interested in what CEM is or was, but on the possibilities themselves. We argue that such analysis leads to an understanding of the group as being an accident involving the individual identities of its members but not to an understanding of CEM’s group identity as such.

As mudanças procedimentais de alunos do ensino médio durante o trabalho com investigação matemática em sala de aula

The paper that if presents, tells a research carried through next to students of the High School, in which activities of mathematical investigation from questions of some examinations of federal and state public universities had been elaborated; later applied to these students in a state school of the inside of São Paulo and with data obtained from their productions, we search to analyze which procedures had been used for them and which procedural changes had occurred. It is intended with this, to collaborate for the mathematical formation of the students of High School aiming at a more significant learning of the mathematical concepts and the procedures involved when working with this type of activity.

O renascer da pós-graduação em poéticas visuais na UNESP, campus de Bauru: contribuição valiosa para os cursos de artes

The postgraduation program in Visual Poetics, Master level, to be started in 2011 at the faculty of Architecture, Arts and Communication of the state university of São Paulo "Julio de Mesquita Filho"- Bauru Campus, arises strong and well structured contributing to the strengthening of Arts courses. It is noteworthy that the Visual Poetics area has graduated in its previously existing program, more than 30 (Thirty) masters and 8 (eight) doctors. They are currently linked to state and federal universities of Sao Paulo, Parana, Santa Catarina and Mato Grosso do Sul . Ricardo Nicola is Post-Doctor by IES since 2007: University of Toronto, Canada, is presented as mentor and coordinator of the renaissance process of masters program in Visual Poetics.Nelyse Apparecida Malro Salzedas , graduated as a Professor in 1993 at the same University, she has contributed significantly to the Program implementation and will be vice-coordinator of the project.

Cómo se puede implementar la Historia Oral en Educación Matemática?

What is known today as “Oral History” is a research methodology which, in Brazil, has been widely used in the field of cultural studies by sociologists, anthropologists, and historians. Oral History was first introduced in Brazil with studies in social psychology and then spread to many other academic spheres, with the field of mathematics education being one of the most recent to adopt this method as one of its theoretical-methodological references. Topics such “What Oral History is” and “How Oral History can be implemented in mathematics education” are the foci of this paper.

Dispositivo estratégico, resistência e relações de poder: um ensaio sobre a identidade do Centro de Educação Matemática (CEM) e seu papel na (E)educação (M)matemática brasileira

This paper presents some results of the investigation on the Mathematical Education Centre (CEM), a group of mathematics teachers’ educators in São Paulo, Brazil, acting mainly between 1984 and 1997. The essay, marked by an effort to constitute the identity of the CEM based on Foucault, assumes that the identity constitution process is not about what CEM is or was, but mainly about a set of possibilities of apprehending it from its historically contextualized strategies and initiatives. In this Foucauldian reading, which brings about concepts such as "strategic device", "resistance" and "power relations", the CEM constitution appears while it creates conditions for the constitution of Brazilian modern mathematical education.

Modelagem Matemática e Análise de Modelos Matemáticos na Educação Matemática

In this paper we present two studies, the first one completed and the second one in development, which are based in teaching approaches that propose the qualitative study of mathematical models as a strategy for the teaching and learning of mathematical concepts. These teaching approaches focus on subjects from Higher Education such as Introduction to Ordinary Differential Equations and Topics of Differential and Integral Calculus. We denominate this common aspect of the teaching approaches as Model Analysis and in a preliminary level we relate it with Mathematical Modeling. Furthermore, we discuss some questions related with the choice of the theme and the role of Digital Technologies when Model Analysis is applied.
