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 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.

Formar professores de matemática no estado do Maranhão, Brasil: aspectos historiográficos

This paper intends to sketch some historical remarks on the formation of math teachers in undergraduate courses in Maranhão State, Brazil, since the 60’s, the decade in which the first of these courses was created. Its methodological approach is given by Oral History and, in order to collect data, some professors and students were interviewed. Such teachers are those responsible for the projects – and its implementation – of the first three undergraduate courses in Maranhão, and the students are part of the first team formed by them in those institutions.

Cartografias contemporâneas: mapa e mapeamento como metáforas para a pesquisa sobre a formação de professores de Matemática

This essay sketches some principles according to which a research project called “Mapping of math teacher education and practice in Brazil” is been conducted by a group of researchers with the objective of understanding the way policies related to teacher education and practice are effectively implemented in different regions of the country. The main objective of this article is, therefore, to discuss the pressupositions of this project, its foundation, the basic beliefs in which it is rooted. In order to emphasize such principles, some remarks on theorization, methodology, teacher education, narratives and on the concept of mobilization/apropriation are done. The essay is based on a metaphor built on cartographical practices.

Origami científico: a linguagem das dobraduras dentro do design contemporâneo

After crossing several generations and countries, broader functions are being incorporated to origami than simply making art objects: the fold initiates a series of new buildings within the design and creation. Under the new repre- sentations and performances that the art of paper folding keeps, this article aims to investigate how the origami is configured nowadays and how it behaves while contemporary language applied to projective processes of diverse natures. To better understand the actual origami, relations are used inside branch of math, conceptual and projectual. Relating theorists, artists, designers, etc., can point out the relevance of each of these areas in the configuration of cientific and projectual origami. The modularity, the collective, the conscious build, the contemporary and the inno- vation are relationships intrinsic to the praxis projectual that shape a landscape adjacent and subordinate to the main structure governing. It bets on the essence of origami as a tangible functionality for creative thinking.

As matemáticas modernas: um ensaio sobre os modos de produção de significado ao(s) movimento(s) no ensino primário brasileiro

The main goal of this paper is to discuss the production of meaning of the Modern Math Movement. The main sources were data available in school archives and interviews with former teachers that we use in order to focus on the diversity of perspectives -that complement it or oppose it-, which comes up when teachers refer to the Movement. Using this process of signification, teachers whether accept it, invalidate it or adapt it to guidelines imposed to them in their teaching activities. We establish a methodology by following the premises of Oral History to gather oral testimonies. The theoretical foundations in which this article is written are the guidelines of Paul Ricoeur’s Hermeneutics, John Thompson’s Depth Hermeneutics and Bolívar’s narrative analysis.

Sensibilização da audição e educação sonora nos exercícios de limpeza de ouvidos: uma incursão na Educação Matemática

The teaching of acoustics has been characterized by a banking model that little contributes to the ideal training of citizens capable of understanding and acting to improve their environment soundscapes. Equally distant from the world of sound and musical culture, audio technology and acoustic environment, it is disconnected from the ever-increasing effort to raise awareness on hearing and sound education, as defended by the Canadian educator Prof. Raymond Murray Schafer. In order to provide elements for reflection on how Mathematics can be itself a language to compete in a sound education, we developed, in a dialogical and problematizing method applied to the technological and cultural world, one further research and teaching with Math students of UNEMAT in Barra do Bugres. This study pointed to the feasibility of educating consciences capable of of improving their acoustic environment, modifying the landscapes where we live, under our responsibility.

O Raciocínio lógico-matemático: classificação e uso em concursos públicos

This study offers an analysis of classification of the main issues of logic and logical thinking found in competitive tendering and math tests, according to their concepts and characteristics, whether involving mathematics, or not. Moreover, a research on the evolutionary historic processes of logic according to three major crises of the foundations of mathematics was conducted. This research helped to define Logic as a science that is quite distinctive from Mathematics. In order to relate the logical and the mathematical thinking, three types of knowledge, according to Piaget, were presented, with the logical-mathematical one being among them. The study also includes an insight on the basic concepts of propositional and predicative logic, which aids in the classification of issues of logical thinking, formal logic or related to algebraic, and geometric or arithmetic knowledge, according to the Venn diagrams. Furthermore, the key problems - that are most frequently found in tests are resolved and classified, as it was previously described. As a result, the classification in question was created and exemplified with eighteen logic problems, duly solved and explained

Uma Proposta de utilização de um software educacional para o ensino de poliedros

This paper presents an educational proposal to use an educational software for the teaching of mathematics, following in the conduct of activities, the main aspects of sociocultural theory of Vygotsky. For this, it chose the Poly educational software, with which were developed teaching and learning activities for the polyhedra content provided in the São Paulo State Mathematics curriculum for the 7th year of elementary school. The objectives of this pedagogical proposal are to stimulate situations of social interaction among students and between students and the teacher, using an educational software as a mediator instrument and present a different way of using digital technology in math classes, aiming production of mathematical knowledge
