A elaboração e instituição do currículo mínimo de matemática no Rio de Janeiro

O currículo traz subjacente a si, as ideias de seu tempo, o olhar de sua sociedade para questões humanas e outras tacitamente políticas. Traz em seu escopo toda uma trama de heranças históricas e a marca pessoal daqueles que se dedicaram a sua construção. E desta forma, analisar as tramas de um currículo de matemática é muito mais que olhar uma sequência de conteúdos linearmente organizados. É, sobretudo, entender, que aquela construção foi tecida de forma a sustentar um corpo de ideias que diz sobre seu tempo. Esta pesquisa evidenciou o processo de elaboração e instituição do currículo mínimo pela Seeduc/RJ e trouxe questionamentos e inquietações de naturezas cognitivas e sociais. Uma primeira inquietação concerne ao descarte de conteúdos do currículo anterior, que configura agora, este novo currículo. Esse processo de elaboração e instituição refletiu a inexistência de diálogo entre os diversos segmentos sociais e profissionais do campo educacional. Interesses governamentais interferiram diretamente nos educacionais, subtraindo a democracia das ações de políticas públicas implementadas. Ficou evidente que não houve clareza conceitual quando dessa e em contraste até mesmo com propostas nacionais e a legislação vigente. Através do Currículo Mínimo buscou-se unificar toda a rede de ensino da Seeduc/RJ, dentro de uma perspectiva academicista limitada, desconsiderando as especificidades locais e de cada grupo. Desta forma, foi desconsiderada a dialética educacional e a retórica da matemática enquanto disciplina acadêmica, que é uma forma particular da relação social. O processo instituído evidencia uma visão de professores passivos e alunos considerados mínimos.

A importância da matemática e da modelação matemática no mestrado integrado em ciências farmacêuticas

A Matemática e as Ciências Farmacêuticas encontram-se relacionadas desde há muito, no entanto, foi a partir do séc. XVII, período de notável agitação cultural e científico que os métodos experimentais foram sustentados com cálculos matemáticos. Esta ciência e as técnicas de modelagem matemática tornaram-se numa ferramenta amplamente utilizada, de tal modo, que nos dias de hoje são consideradas como fundamentais na generalidade das profissões e em especial nas Ciências Farmacêuticas. Contudo, para muitos ainda não é vista como fundamental e essencial para a formação de futuros farmacêuticos. Deste modo, pretende-se demonstrar como a Matemática e as técnicas de modelagem se tornaram ao longo dos anos nesta poderosa ferramenta. Quer pelos instrumentos, quer pelas competências que nos proporcionam. Pretende-se também, com recurso aos conteúdos programáticos desta unidade curricular, avaliar se os conhecimentos, sistemas de avaliação e distribuição da carga horária são efetuados de forma homogénea pelas diferentes instituições portuguesas, públicas ou privadas que lecionam o Mestrado Integrado em Ciências Farmacêuticas. Verificou-se que a Matemática é uma ciência plena de capacidades e recursos e que estabelece uma relação interdisciplinar com as Ciências Farmacêuticas. Quer pela componente utilitária, quer pela componente formativa que proporciona. A análise dos conteúdos programáticos demonstra que apesar de serem transversais, as Universidades que não lecionam Sistemas de Equações Lineares e Equações diferenciais deveriam faze-lo e também realizarem um melhor controlo da carga horária por temática.

Professor de matemática : transmissão de conhecimento ou construção de significados?

Esta tese expõe minhas reflexões sobre a prática docente de matemática em classes de ensino fundamental. Tem como referencial básico a teoria da abstração reflexionante, como proposta por Jean Piaget, complementada por reflexões sobre a formação do juízo moral e sobre conseqüências pedagógicas pensadas a partir da Epistemologia Genética. Para a coleta de dados foram entrevistados professores, matriculados no Curso de Especialização em Educação Matemática da Faculdade de Educação da Universidade Católica de Pelotas. As entrevistas, desenvolvidas segundo o método clínico piagetiano, buscaram elucidar como se desenvolve o trabalho do professor com o ensino de matemática, enfocando suas concepções de matemática, assim como sua compreensão do processo de ensinar e de aprender. Para o professor, a matemática pode ser descrita como uma ferramenta que descreve quantitativamente idéias a respeito do mundo; ou como um sistema independente, abstrato, fixo, lógico e livre de contradições ou ainda como uma disciplina rígida, cheia de definições, teoremas e procedimentos de caráter absoluto. Em todos os casos cabe ao professor transmitir informações e conduzir os alunos em direção a objetivos pré-definidos, além de exercer a autoridade e o controle disciplinar da turma, permanecendo a aprendizagem como uma decorrência direta do ato de ensinar exercido pelo professor. Considerando minha história de vida como professor, a análise do processo evolutivo do pensamento matemático, as falas dos professores entrevistados e os posicionamentos teóricos colhidos na epistemologia genética proponho, ao final, um conjunto de ações que entendo serem indispensáveis para o desenvolvimento de práticas de ensino e aprendizagem de matemática que assegurem a condição de sujeito de seu fazer tanto ao professor quanto ao aluno.

Ateliês de história e pedagogia da matemática: contribuições para a formação de professores que ensinam matemática nos anos iniciais

This paper presents a discussion about the use of the History of Mathematics as an educational resource and conceptual mediator in the formation of teachers who teach mathematics in the years of elementary school. It was a qualitative action method, in order to show the importance of holding workshops of History and Pedagogy of Mathematics as contribution to overcome the conceptual difficulties of teaching and teachers regarding the content covered in the course of education and afterwards they have to teach in the early of elementary school. We assume that understanding the historical, social and cultural comprehension as a conceptual and didactic focus effectively nurture the pursuit of a teaching and learning of mathematics students safe and justified in order to contribute to overcoming the difficulties of teaching and learning usually occurred in the classroom of the early years. In this sense, we organized a study group formed by students of Bachelors in Education and Mathematics at the University of Piauí. We developed five training workshops in History and Pedagogy of Mathematics, with a workload of 20 hours each and four follow-up sessions and advicement, totalizing 180 hours. The purpose of workshops was to develop studies on the History of Mathematics that could support the formation of a conceptual and didactic group with a view to prepare teaching materials and activities based on information drawn from undertaken historical studies .The products designed were used in formation of the group itself and will later be used in training teachers of public school in Teresina, in the form of workshop of History and Pedagogy of Mathematics in order to overcome problems arising from teaching and conceptual this education degree in Education Based on the obtained informations it was possible to suggest new referrals procedural level of education and university extension that may contribute to the reorientation of initial and continuing training of teachers in the early years elementary school

A tabela periódica: um recurso para a inclusão de alunos deficientes visuais nas aulas de química

Nowadays there are many reasons that aim to include people with special necessities, like those with visual deficiency, in the world of work, education, and in the society as a whole. However it is observed that when we talk about schooling inclusion, especially in High School, there is a huge gap between the theory and the practice. The lack of didactic resources, the inadequate installations, unprepared teachers, the families´ lack of information, are some of the factors that hinder the process of inclusion. Furthermore, the educators also have to deal with the roughness of the disciplinary contents and, refering to the study of Chemistry, with the use of signals related to this subject´s language. So, the objective of our research is to reflect about the apprehension of this language by the visually handicapped people, and try to contribute with their process of inclusion in the school life. On this perspective we work with the Periodic Table, which constitutes one of the indispensable tools necessary to the Chemistry learning. In order to acomplish it, the way followed by us happened in three passages. Initially, by means of a semistructured interview, we tried to get acquainted with the blind students opinion, who were participating in the research about the Periodic Table used by them throughout High School, as well as the dificulties felt when using it. After getting the answers, the Table was reelaborated to fill those students´necessities. Here, two new Tables were designed, one in Braille which shape is more compacted, and another made with high printed dots, built with sand and glue. On the third moment, the new designed Tables were tested by the students and, by means of a semi-structured interview, we tried to identify if this new resource would solve the problems concerned to the old Table. The students showed that the compacted Tables would facilitate the touch reading of the chemical elements simbols, making it clear and fast. We hope that, with the elaboration of this learning tools we can contribute with one of the elements to favor the effective participation of blind students in Chemistry classes, when studying the Periodic Table

Aprendendo e ensinando o sistema de numeração decimal: uma contribuição à prática pedagógica do professor

The central question of the present study is to identify the epistemological knowledge that the teachers-trainees possess regarding the characteristics (properties) of the decimal numbering system; its purpose is to offer a contribution to the pedagogic practice of the teachers who work within the Basic Literacy Cycle, in terms of what concerns both the acquisition of contents and the development of the knowledge that helps them in the elaboration of adequate strategies to working with the Decimal Numbering System in the classroom. The study is based on the constructivist sociointeractionist approach to teaching Mathematics and it constitutes, in itself, a methodological intervention with the teachers-trainees engaged in the Professional Qualification Program in Basic Education of the Federal University of Rio Grande do Norte. The foundations of the study were found in investigations of researchers who had carried out studies on the construction of numerical writing, showing, for instance, that the construction process of ideas and procedures involved in groupings and changes to base 10 take a lot longer to be accomplished than one can imagine. A set of activities was then elaborated which could not only contribute to the acquisition of contents but that could also make the teachers-trainees reflect upon their teaching practices in the classroom so that in this way they will be able to elaborate more consistent didactic approaches, taking into consideration the previous knowledge of the students and also some obstacles that often appear along the way. Even when teachers have access to the most appropriate dicactic resources, the lack of knowledge of the content and of the real meaning of that content make the Decimal Numbering System, a subject of fundamental importance, be taught most times in a mechanical way. The analisys of the discussions and behaviours of the teachers-trainees during the activities reavealed that they made them reflect upon their current practices in the classroom and that, as a whole, the aims of each of the activities carried out with the teachers-trainers were reached

Uma análise dos questionamentos dos alunos nas aulas de números complexos

This work presents a contribution for the studies reffering to the use of the History of Mathematics focusing on the improvement of the Teaching and Learning Process. It considers that the History of Matematics, as a way of giving meaning to the discipline and improve the quality of the Teaching and Learning Process. This research focuses on the questions of the students, classified in three categories of whys: the chronological, the logical and the pedagogical ones. Therefore, it is investigated the teaching of the Complex Numbers, from the questions of the students of the Centro Federal de Educação Tecnológica do Rio Grande do Norte (Educational Institution of Professional and Technology Education from Rio Grande do Norte). The work has the following goals: To classify and to analyse the questions of the students about the Complex Numbers in the classes of second grade of the High School, and to collate with the pointed categories used by Jones; To disccus what are the possible guidings that teachers of Mathematics can give to these questions; To present the resources needed to give support to the teacher in all things involving the History of Mathematics. Finally, to present a bibliographic research, trying to reveal supporting material to the teacher, with contents that articulate the Teaching of Mathematics with the History of Mathematics. It was found that the questionings of the pupils reffers more to the pedagogical whys, and the didatic books little contemplate other aspects of the history and little say about the sprouting and the evolution of methods of calculations used by us as well

Reestruturação da disciplina "Física I" do Curso de Tecnólogo em Gerência de Obras de Edificações do CEFET/PB

The aim of the present paper is to reorganize a discipline on technological physics so that the construction site of civil engineering becomes a natural environment of learning, providing the learner with the association between theory and practice as well as allowing the subject to process, in real time, information generated from his cognitive constructions and his contextualizations. Thus, a sequence of actions was taken into account: firstly, the programme was developed in the classroom, sharing with its contextualized information through experiments done under supervision by the learners in laboratories; secondly, the data which associate physics with construction were collected and, to do so, technical visits to construction sites were realized, providing the learner the association between the theory and the practice in a suitable site to the constructivist approach. As a result, the first discipline on physics of the Curso de Tecnólogos em Gerência de Obras de Edificações do CEFET/PB was re-structured in terms of syllabus, methodology, application and evaluation. In fact, this work deals with a dynamic process that gathers and gives emphasis to teaching, learning, technology, information, creativity, competence and abilities in a constructivist learning process and, as a consequence, having allowed institutional engagement

A Compreensão da idéia do número racional e suas operações na EJA: uma forma de inclusão em sala de aula

The awareness of the difficulty which pupils, in general have in understanding the concept and operations with Rational numbers, it made to develop this study which searches to collaborate for such understanding. Our intuition was to do with that the pupils of the Education of Young and Adults, with difficulty in understanding the Rational numbers, feel included in the learning-teaching process of mathematics. It deals with a classroom research in a qualitative approach with analysis of the activities resolved for a group of pupils in classroom of a municipal school of Natal. For us elaborate such activities we accomplished the survey difficulties and obstacles that the pupils experience, when inserted in the learning-teaching process of the Rational numbers. The results indicate that the sequence of activities applied in classroom collaborated so that the pupils to overcome some impediments in the learning of this numbers
