Este trabalho é uma pesquisa narrativa autobiográfica, que expõe a análise das minhas praxeologias, no contexto do meu desenvolvimento profissional, como professor de matemática. O foco da análise recai sobre os diversos conflitos praxeológicos que vivi durante a elaboração e aplicação em sala de aula de uma proposta didática para ensinar operações polinomiais na sétima série (oitavo ano) do ensino fundamental. Com esta pesquisa pretendi responder a seguinte questão: Quais conexões entre aritmética e álgebra determinaram as minhas praxeologias durante a ampliação didática que desenvolvi, para ensinar adição, subtração, multiplicação e divisão de polinômios, na sétima série (oitavo ano) do ensino fundamental? Para analisar as minhas próprias praxeologias a partir da proposta didática que elaborei, assumi a Teoria Antropológica do Didático (TAD) de Yves Chevallard como referencial teórico principal. A análise que fiz das minhas próprias praxeologias envolveu sistema de numeração decimal, operações aritméticas fundamentais, operações polinomiais, tipos de tarefas e técnicas, universo cognitivo e equipamento praxeológico. Os resultados apontam que as minhas relações pessoais com tipos de objetos ostensivos e não ostensivos e tipos de tarefas e técnicas presentes ou não na proposta didática que elaborei, revelam quais praxeologias passadas e presentes compunham os diversos momentos do meu desenvolvimento profissional como professor de matemática. Assim, antes da graduação vivi as praxeologias de professor leigo, durante e após a especialização o meu universo cognitivo passou por conflitos praxeológicos, revelando que as sujeições institucionais conformavam as minhas praxeologias para ensinar as operações polinomiais.

Considering the necessity of implementation of the Information Technologies and Communication (ICT) in the public Brazilian schools, the São Paulo State government hearing the call of the federal government and, with the objective to promote the digital inclusion, created the Programa Acessa Escola. The research that we realized and bring expressed on this text, is about such program and allowed us comprehend how it had been developed in the public state schools of the city of Guaratinguetá. By visiting the schools, we saw the manner that each school make use of his informatics laboratory; how they understand the government Project; how they develop actions of use of the laboratory and, particularly, how they use the informatics laboratory to the teaching and learning of mathematics helping the professor and the students. To make possible to understand this use, was realized interviews with the responsible intern of each one of the 14 (fourteen) schools of Guaratinguetá; with the pedagogical coordinator or director of the school and with the mathematics teacher. By the analysis, realized using a qualitative approach of phenomenological nature, we understand that the intern see himself as an auxiliary of the student and professor in the use of the laboratory. The director or pedagogical coordinator understand that the laboratory is an excellent resource to the school, but still exist the necessity of more resources that allow to attend properly the community; and the mathematics teacher consider important the program in the school as much for the students digital inclusion as for the teaching but they feel not safe to use into his classes, because they consider that there is a lack of capacitation and collaboration to make their activities relevant to the learning. That make possible to recognize what is the function of the intern and what is the way that the students and professor ... ( Complete abstract click eletroctronic access below)

This research presents a study on mathematics teacher education, examining the bibliographic production in 15 years of the journal Zetetiké (1993-2007), totalizing 140 papers. From these, 49 were classified as ‘teacher formation’, thus constituting the corpus of the investigation. The research focused on three units of recording and analysis: (i) problems of research; (ii) the meanings of ‘being a teacher’ and their ‘duties’; and (iii) the meanings of ‘teacher’s education’. For the processes of categorization we use Textual Analysis, which allowed us to observe some trends. Regarding the problems of research we found that the research actions involve a range from: to report, disclose, describe, identify up to study, discuss, understand, evaluate. With reference to ‘being teacher’ and its ‘duties’ in the whole period of this study it were pointed problems related to the mathematical content and to the pedagogical project of the school unit, with 30 papers giving prescriptions for the teachers actions in its educational context. With regard to the meanings on teacher education, the most frequent references concern: the functions of teacher formation; what is expected of the teacher during and after the education processes; and the emphasis on the importance of initial formation for mathematics teacher’s education.

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.
