Aulas práticas para o ensino de Ciências e Biologia: algumas propostas

Os Parâmetros Curriculares Nacionais (PCNs), indicam que o ensino de ciências deve contribuir com eficiência para o desenvolvimento de uma sociedade mais esclarecida, que consiga compreender os avanços científicos e tecnológicos do mundo. Com isso, o ensino das ciências naturais pode ser articulado, apresentando-se de forma interdisciplinar, pois abrange aspectos da Física, Química, Biologia, incluindo Ciências Sociais e Tecnológicas. Focado nessa proposta, esse trabalho tem como finalidade disponibilizar ao professor de Ensino Fundamental aulas experimentais e práticas para serem utilizadas nas escolas. Consiste em uma lista de experimentos, entre outras práticas, organizados segundo os Eixos Temáticos previstos no PCNs. As práticas selecionadas se apropriam de materiais simples, de fácil obtenção e custo reduzido, podem ser realizadas tanto em ambiente laboratorial como em sala de aula, viabilizando sua utilização. Todos os experimentos foram extraídos de diferentes fontes de pesquisa: livros didáticos, apostilas didáticas e da Rede Internacional de Telecomunicação (Internet). Espera-se com esse material que o professor encontre um suporte para auxilio em aulas práticas, que proporcione ao aluno, atividades dinâmicas, facilitando a interação do educando com o conhecimento, atingindo o principal objetivo, a aprendizagem

Um levantamento bibliográfico no período de 2008-2013 sobre a alfabetização científica nas séries iniciais para o ensino de física

This study aimed to review the publications in the area of Education Physics that has contributed to Scientific Literacy and STS - Science , Technology and Society , with students of elementary school in Basic Education , looking for understand the importance of an education that aims the formation of critical citizens, in opposition to passive recipients of technological influences of a modern society , but which are able to understand and reflect the importance and influence of science and technology in political, social and environmental to society . In this context , the Physics, is one of the areas of natural sciences with direct implications in daily life , we believe in the importance of introducing physical concepts in science education since the early years of basic education , either as a approach playful , experiment, study of books , magazines , papers , etc. . , so that the knowledge about physics can be built through experience and the analysis of daily phenomena, instead of only being addressed in the last three years of teaching average basic education

A matemática no ciberespaço: um olhar fenomenológico para a expressão dos sujeitos

With the implementation of new technologies on the world stage of communication, Internet access has become increasingly numerous. Being sought by this means all kinds of information, from knowledge to entertainment. This paper intends to report the experience in two communities of the Internet, particularly in the social network Orkut, entitled I Hate Mathematics and I Love Mathematics, whose members are students, teachers and people who want to express how they feel about mathematics. The goal is to understand what took the members of these communities to hate or love Mathematics, clarifying the nature of the network Orkut and its contribution to mathematics education. For the analysis of data from field work, we use the phenomenological approach. The procedures followed by such approach allowed us to build four open categories: Research and Background, revealing that the research activities allow students to develop strategies, develop creativity and shows that what is learned in classroom is not just an accumulation of knowledge; Teacher's Role shows that it is necessary that the teacher understands the meaning of being a teacher and worry about being a student; Acquisition Technique, it is necessary that students be able to understand what is done and how it is done, and Sense of What is Done, to do is not directly linked to comprehend. The interpretation of these categories helped us understand the investigated giving us source to analyze how Information and Communication Technologies (ICT) can help the teacher understand the student's relationship with Mathematics

Matemática e Arte: interdisciplinaridade

The objective of this study is to perform a theoretical study of the possible relationship between mathematics and art. For some people, the association between these fields of knowledge may simply seem absurd, possibly because they do not know what is in common between an area considered rigorous, rational, objective, and a more emotional, intuitive, subjective. In this context, interdisciplinarity has an important role, in proposing the contextual integration between the subject content, such as projective geometry and the renaissance. Are also presented as examples of this union, the technique of Moses and the geometric patterns of indigenous crafts, as well as the work of artist Maurits Cornelis Escher, a legitimate representative of the relationship between art and mathematics

A utilização de sólidos geométricos com alunos do ensino fundamental

This research analyzed if the interactions between teacher and student, and among students, with the use of manipulative materials in the Mathematics teaching in a middle school class and provided the comprehension of the subjects worked. The analysis of the results was based in Vygotsky’s socio-historical theory, that prioritizes the interactions in learning-teaching process. The results of this research showed that these interactions mediated by the use of such materials provide the student with the motivation needed to take part in the math classes as an active actor in his development process, as well as understanding the concepts

Etnomatematica: psicologia aplicada à educação matemática

Investigations in ethnomathematics show that there are several cultural forms of mathematics, mathematics different dominant. Currently, most research in ethnomathematics aim an ethnographic study of anthropological or cultural groups. However, there is a strong need for studies in ethnomathematics is to target the pedagogical action, involving the teachinglearning practices. So the big challenge for researchers in ethnomathematics is the development of study and teaching practices in line with the objectives philosophicaltheoretical Program Ethnomathematics

Análise de uma avaliação diagnóstica de matemática: de uma escola estadual de Rio Claro

A pesquisa consiste na análise de uma avaliação diagnóstica aplicada em escolas estaduais do Estado de São Paulo no ano de 2012, essa avaliação é concedida pelo próprio Estado, porém essa análise se restringe em apenas uma escola com cinco salas de sétimos anos, totalizando cerca de cento e trinta alunos. O objetivo é examinar as provas de matemática e através dos resultados verificarem se as habilidades e competências dos alunos estão de acordo com o nível esperado para o ano em que se encontram, para realizar essa análise será feito a tabulação dos resultados que será apresentado em forma de banco de dados e tabelas, e também será realizada a análise descritiva. Também será falado quando e o porquê surgiu esse sistema de avaliação e as mudanças que teve ao longo do tempo

Efeitos da experimentação no cotidiano letivo no ensino médio

In this work, it was studied the effects of the experimentation in the physics teaching. Beginning from the theoretic reference and discussions, the objective was prove the efficiency of researches of this nature related to two main aspects of a class: The aroused interest in the students and the facilitating action on the understanding of the theory. For such objective, using the comparison, it was chosen two distinct classes, but the more similar possible, so that, in one of them, it was showed a tradition class, lectures and in another, a class using experimentation to contemplate the theory. To manage a way to rate these aspects, it was made a conceptual questionnaire, requiring only concepts rather than mathematics and equations, besides specific interviews to rate the opinion of the student related to each method. The observations in classes and of the reactions of the students also were of a big value to analysis. After the experimental class completed, it may analyze and conclude some positive points related to experimental methods: As for the opinion of the students, the approval was big, and the majority opined to this class as being “more interesting”. On the point of view of learning, it had a sensitive improvement of grades, but with more mature answers, deep and autonomous, if looking at a general vision

Aprendizagem dos alunos de 5º ano do ensino fundamental em aritmética e suas dificuldades na resolução de problemas com estrutura multiplicativa

The topic in this work involving the resolution of problems with structure multiplicativa emerged from discussions carried out on the difficulties encountered by students of the first cycle of the Fundamental School in Mathematics, mainly in respect of the arithmetic. The research had as objective to investigate the main difficulties presented by these students when they are faced with a task for a resolution of problems with multiplicativa structure. Were participants, in the first stage of the study, 20 students of the fifth year of the Fundamental School of a state school of public education of the State of Sao Paulo. These students have an assessment containing ten problems with structure multiplicativa answered a questionnaire regarding of mathematics. In the second stage, were selected two students to participate in the think aloud. The data analysis showed that the difficulties presented by the participants were: 1- difficulty to read and interpret the set of problems; 2- select the operation correct; 3- to operate correctly; 4 – Trouble writing

Um Estudo da modelagem matemática na educação matemática e seu potencial para o desenvolvimento do pensamento crítico

The implementation of mathematical modeling curricula represents a great challenge, both for teachers and students, since it escapes the traditional teaching methodology, i.e. when the teacher speaks to his/her students. This work presents, at least, one possible way of implementing mathematical modeling inside the classroom, and how this way encourage critical thinking in students. I see mathematical modeling as an opportunity to minimize student's rejection and increase their interest for mathematics, promoting their competencies to give points of scene in every day situations. The history of mathematics shows that mathematical modeling had developed since almost the beginning of human live, when men needed to solve problems that arose in the course of his life. Mathematics has become more and more abstract, but it is important to recall what was originated it. In this way, it is possible to make this subject matter more meaningful to students. I will make an introduction of mathematical modeling, presenting some important definitions. Based on this framework, I will present a classroom instruction understand on a 7 th grade classroom by myself. With this in instruction I sustain the idea that mathematical modeling has, in fact, a great potential to improve the quality of mathematics teaching. I also sustain that, the development of critical thinking, as a competence, way be achieved with it

Contribuições da leitura e escrita para a aprendizagem da matemática com textos de diferentes contextos

This work aims describe, through a phenomenological approach to qualitative research, which are the contributions of reading and writing of texts from different contexts for learning mathematics. For this purpose, we developed activities involving reading, writing and math in classes in the 6th grade of elementary school to a state school Guaratinguetá. These activities constituted the research data as part of the fieldwork. We analyzed the data following the procedures of this phenomenological research which they are described by Bicudo (1994, 2000, 2011), Fini (1994) and Machado (1994). We base our study on reading, writing and mathematics in Nacarato (2009), Lopes (2009), Smole (2000) and Fonseca (2005), among others. In the analysis, we seek to clarify how meaningful situations of different contexts, helping to develop skills in reading, writing and interpretation of the student, which in turn help the students at understanding mathematics. After the analysis of data, we named the two open categories: Difficulty of Expression and Communication Facilities. The interpretation of categories allows us to understand that there is, by individuals, a communicative intention that is expressed in the texts

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

Tema transversal saúde na escola: diagnóstico e possibilidades

Introdução: A sociedade brasileira tem sofrido grandes transformações nessas últimas décadas e o papel da escola e sua importância também. Com a queda da Ditadura Militar, que vigorou de 1964 até 1985 e com a promulgação da Constituição da República em 1988, que teve como um dos objetivos principais a inclusão social, entre outras iniciativas no âmbito das políticas educacionais, foi dado início à elaboração dos Parâmetros Curriculares Nacionais, cuja primeira publicação se deu em 1997. Assim, além das disciplinas tradicionais como: Língua Portuguesa, Matemática, História, Ciências Naturais, Geografia, Artes e Educação Física, a escola também deveria trabalhar os chamados Temas Transversais: Meio ambiente, Ética, Pluralidade Cultural, Saúde, Orientação Sexual e Trabalho e Consumo, temas esses, que devem permear toda a prática educativa. Como será que as escolas vêm desenvolvendo a proposta de Temas Transversais? Será que a saúde é uma preocupação? Se a resposta for afirmativa, de que modo ela vem sendo conduzida? Objetivo: Baseado nos Parâmetros Curriculares Nacionais, este trabalho pretendeu avaliar a importância do tema transversal Saúde, bem como investigar os impactos desse documento na educação escolar do ensino fundamental. Metodologia: Para tanto, serão realizadas pesquisas bibliográficas e também documentais da escola, como o projeto político pedagógico e os livros didáticos utilizados. Conclusões: As conclusões elencadas neste trabalho são que o tema transversal Saúde é pouco trabalhado no ensino fundamental, devido, entre outros fatores, ao despreparo do professor e a concepção equivocada que ainda há nos educadores relacionando saúde às doenças e à higiene unicamente

O ensino da lógica na educação básica

This work has as its aims to offer a general view on the teaching of logics in the basic education by means of different materials on the theme. There are highlighted considerations on academic works in the area of math education that claims the teaching of logics on basic education as a means of developing the reason and promote the learning. It is done a bibliographic review on works that approach the theory of formal logics that presents different ways of working the teaching of logics. The curricular proposition of São Paulo State for the Math area is analyzed and its characteristics are discussed. The learning evaluation in a large federal scale for the teaching of middle and basic education are detailed in its matrix of references and content approached in its editions searching the evidences of a logical reasoning worth. A portal M3 Multimedia math is presented in activities in video format for the teaching of logics. After an analyze of the references where the focus was related to the learning of Math by means of an approaching where logics acts as a tool. It is possible to consider that there is a relevant number of researches and publishing in the area of Math education that approaches the concepts of formal logics. There is also evidences of a changing in National and State orientations for a basic education that reflects in its didactics resources and evaluations in a large scale. Even though, we can face difficulties on implementation of these proposes that is pointed out by constant critics by teachers concerning the changes in the resources and cited evaluations by the resistance of a considerable percentage of teachers to adopt the didactics materials distributed by the State and by the low performance of students in Public Schools in tests of learning

A física no 1º ciclo do ensino fundamental: uma abordagem construtivista

Todos nós sabemos o quanto é importante uma base de conhecimentos sólida, para que, posteriormente, quando forem ensinados os novos conceitos, os alunos possam fazer relações com o conhecimento que já possuem, com maior facilidade. Verificamos no Ensino Médio a grande dificuldade dos alunos têm para o aprendizado de Física, além da idéia pré-concebida que eles possuem de que é uma disciplina de difícil compreensão. Porém, essas dificuldades, em sua grande parte são advindas da compreensão dos textos de e do desenvolvimento de cálculos, ou seja, essas dificuldades provêm das disciplinas de Língua Portuguesa e de Matemática. Com base na situação descrita acima, o presente trabalho tem o objetivo de buscar alternativas para este problema, trabalhando desde a base destes conhecimentos, através de atividades desenvolvidas com o primeiro ciclo do Ensino Fundamental. Dessa maneira, levamos para escola pública de um bairro periférico de Presidente Prudente, mais especificamente, para a 3ª série do ensino fundamental, uma atividade com conceitos de Física para desenvolver com as crianças, estimulando o raciocínio das mesmas e a incentivando a busca por soluções para situações-problemas, utilizando-se para isso das idéias propostas pelo Construtivismo, fundamentadas na epistemologia de Piaget. Este trabalho sempre visou a valorização do conhecimento prévio desses alunos e estabelecendo relações com o seu cotidiano
