ResumoO propósito deste artigo é problematizar o papel da filosofia na pesquisa historiográfica em Educação Matemática. Para isso, fazemos a filosofia terapêutico-gramatical do filósofo austríaco Ludwig Wittgenstein contracena com a filosofia desconstrucionista do filósofo franco-argelino Jacques Derrida, sobretudo em referência a um aforismo das Investigações Filosóficas, de Wittgenstein, que compara a nossa linguagem a uma cidade antiga. Palavras-chave:Pesquisa Historiográfica. Educação Matemática. Terapia Wittgensteiniana. Desconstrucionismo Derridiano. AbstractThe purpose of this article is to discuss the role of philosophy in the historiographical research in mathematics education. For this purpose, we make the therapeutic grammatical philosophy of Austrian philosopher Ludwig Wittgenstein act with the deconstructionist philosophy of French-Algerian philosopher Jacques Derrida, especially in reference to an aphorism of Wittgenstein's Philosophical Investigations comparing our language to an ancient city.

Este trabalho foi elaborado em tópicos autônomos para discutir a configuração da educação matemática como área de pesquisa e, num panorama histórico, expõe e analisa como têm sido implementados, efetivamente, esforços para sua consolidação no Brasil. A partir da apresentação de alguns elementos relativos à emergência e à organização da pesquisa em educação matemática no panorama internacional (D'Ambrósio), ele passa a esboçar as motivações e estrangulamentos que levaram à criação de um grupo de trabalho específico sobre educação matemática na ANPEd (Igliori). Miguel e Garnica, por fim, discutem, sob referenciais distintos, a disciplinarização da educação matemática. São, em resumo, quatro olhares e vozes que, ora em fina sintonia, ora em contraponto, surgem fincados no espaço que os autores desejam, com seus discursos, ver consolidado: a educação matemática.

In the first part of this paper, we share and elucidate the way we mobilize histories in some disciplines that are part of the undergraduate courses in mathematics teacher education offered by State University of Campinas and Federal University of Rio Grande do Norte in Brazil. This way of mobilization can be featured as a set of collective indisciplinary problematizations occurring in a series of student investigations. Mobilizing practices of mathematics culture are the object of these investigations. These practices are performed by different communities both constituted by and constituent of different human activities. In the second part of this paper, we will discuss our way of mobilizing histories, contrasting it with the theoretical perspective of expansive learning, just as it has been defended by Yrjö Engeström, in his article Non scolae sed vitae discimus-towards overcoming the encapsulation of school learning. We will also attempt to highlight the role which this researcher has attributed to history in his model of expansive learning, a perspective based on the current research on activity theory.

This article provides an account of published research in environmental pollution carried out in South American institutions within the past 10 years. Because of the broadness of the topic, the continental dimensions of the assignment, and limitations of space and time, the article focuses on environmental research related to air, water, food, and soil. Thus, it is not a complete record, but rather a sample of pub-

We present and discuss in this article some features of a research program whose central object of investigation is the way in which the recent fields of history, philosophy, and sociology of mathematical education could take part in a critical and qualified manner in the initial and continuing training of teachers in this area. For that, we endorse the viewpoint that the courses for mathematics teacher education should be based on a conception of specificity through which a new pedagogical project could be established. In such project those new fields of investigation would participate, in an organic and clarifying way, in the constitution of multidimensional problematizations of school practices, in which mathematics would be involved, and that would be guided by academic investigations about the issues that currently challenge teachers in the critical work of incorporation, resignification, production, and transmission of mathematical culture in the context of the school institution.
