Da prescrição curricular ao currículo como ação compartilhada: dilemas das tentativas de renovação dos programas de ensino de Matemática no estado de São Paulo pós-64

The present study is the result of joint actions between education, research and outreach that is focused on the training of educators and its implications for the renovation of teaching Mathematics. Its objective is to analyze the attempts to reorganize in mathematics curriculum implemented in the state of São Paulo in the post-64. It makes use of documentary analysis and interviews of teachers for reasons of discussion and conclusions. Situated in the theoretical and methodological context of collaborative research and historical-cultural theory. The research results which shows that mathematical activity is the centrality of the discussion about learning mathematics, which has consequences for the organization, of teaching programs. This is a genesis school thinking that motivates the students to the reconstruction of ideas and thinking a production process in the classroom that considers the conditions of the school, other than the conditions that governs the production of knowledge of mathematical science, which requires thinking about the formation of a teacher epistemologically curious.

A perspectiva metodológica da resolução de problemas: um estudo sobre enunciados de situações matemáticas na EJA

In this paper we discuss the importance of a methodological perspective of solving problems as a sustaining process of teaching mathematics situated on the perspective of concept formation. Organizing a significant didactic situation for students imposes the need to study the interaction between them and the teacher and between them and their mathematical knowledge, learning environment in which the mere transmission of content gives way to contextualization, to historicizing and handling of topics from intuitive and everyday situations for the student. Thus, we understand mathematics as a fundamental language for the creation of theoretical thinking as a whole. We made use of documental analysis and classroom situations aiming at the use of instructional procedure related to the resolution of problems with the purpose of overcoming some representations about the process of teaching and learning mathematics which is strongly marked by imitative-repetitive algorithmic procedures. Considering mathematics as an investigation discipline, we point out renewal prospects for the curricula of this discipline, which are concrete in the movement of cultural action of the school itself as the cell generating discussion.

Educação Matemática e Sociedade

The paper's aim is to justify the creation of the line of research Mathematics Education and Society in the Graduate Program of Mathematics Education (PPGEM), UNESP (Rio Claro, SP). In a brief history of the constitution of the mathematics education community, the categories culture and society were emphasized. A brief summary of sociology is presented, drawing on classical sociologists and contemporary authors. The group EMsociedade is presented, and its purpose, which is to be part of the PPGEM to establish a space for discussions between students and supervisors from the Graduate Program, elementary and middle school teachers, and others who have interest in the subject. One of the arguments defended by the group is presented: institutionalized mathematical knowledge in the Twentieth Century is a commodity. Finally, some future considerations are outlined, including the expectation that the line of research Mathematics Education and Society will be included in the PPGEM.

Educação de jovens e adultos: a construção das operações aritméticas em matemática

Working with adult students who attend literacy rooms has been set a challenge for educators, especially with regard to issues of learning mathematics. This work of course completion intention was to investigate the process of construction of arithmetic operations in mathematics from the perspective of the students themselves. Thus specific objectives were to investigate how these students face simple operations that can do this automatically on a daily basis, but not always systematized in the classroom; how these students think and communicate their ideas to the mental operation of the paper record. To this end we chose a qualitative research approach with characteristics of case study, conducted in a room of Youth and Adult participants with three ladies. The data collection occurred through the application of a semi-structured, audio recorded and later transcribed, which issues the verbalization sought and a description of how to give students the learning process of some mathematical content. The results showed that students bring with them skills, cultures and values to the classroom and that these are the basis for understanding the content. The teacher of adult education must take into consideration everything that the student brings to the classroom, their experiences, their history and culture, thus questioning the real world, so they can understand math in a way closer to their daily lives

Contação de histórias e educação crítica: uma proposta didática

This proposal offers a possibility of approximation of mathematical knowledge at the prospect of Critical Education defended by researchers such as Ole Skovsmose and Paulo Freire. Using storytelling as a methodological resource is intended to develop an activity that allows students to think critically about real-life situations that have democratic questions as ground. The research is part of the branch of mathematics concerned with the education goals of teaching mathematics in basic education. We discuss the relevance of an educational process that enables the development of a democratic competence in the first years of primary education by showing students that their classroom can and should be seen as a community, where everyone has rights and duties. The interpretation and understanding of real situations can be something very complex and uninteresting for students of that age, looking for an attractive feature such as storytelling, which is based on the tendency of Reading and Writing in Mathematics, proposed by Nacarato and Lopes; Cardoso and Fonseca. Adopting a phenomenological attitude in the research seeks to understand if the storytelling can contribute to the formation of the critical student. Assuming this perspective has developed a didactic sequence from the story 'o que os olhos não vêem' from writer Ruth Rocha. The student's writing, favored by the proposed sequence, subsidizes the understanding of their thinking and acting on the democratic situations

As (im)possibilidades da etnomatemática no ensino escolar

This work aims to raise the possibilities of the use of the Ethnomathematics in the teaching of school mathematics, especially in aspects related to socio-cultural issues, in view of its universal character and its importance for the understanding of mathematics as a human construction. The teaching of mathematics is influenced by a belief that mathematics is only for the intelligent. With this, she assumes, consciously or unconsciously, a characteristic of social segregation and intellectual who has served as domination of the masses. Thus, this study may contribute to the teacher entered the school environment offering you one more tool in an attempt to succeed in the teaching and learning. We have forwarded this research in the theoretical literature, gathering input for the near future we can verify their efficacy or, more daring, we can contribute to an educational proposal that has as a prerequisite to sociocultural factors that underlie the teaching and learning of mathematics and that it will meet the real needs of the population

A importância do planejamento financeiro: uma abordagem de matematica financeira para o ensino médio com o uso do excell

The financial health of a family is one of the main generators of quality of life, and this is only possible through financial planning, which is nothing more than save and analyze before contracting debts. To do this, students must have notion of financial mathematics, especially of that used by the banks on overdraft interest, in investments and in the short-term and longterm loans, that is, compound interest, equivalent rates, depreciation and others. Starting from the knowledge of arithmetic and geometric progressions and, based on real situations which allow the application of the content learned, one intends to develop activities applied to high education. To start from real situations is one of the main lines of thought of the Problem Solving Methodology, in which the student is the active agent in the construction of his or her knowledge. As the National Curricular Parameters point out, the practice in the use of computers is essential for gaining a job. Therefore, this project proposes an activity where knowledge of Financial Mathematics can to be practiced, associated with the use of Microsoft Excel® spreadsheet
