História do desenvolvimento do conceito de força: um estudo visando contribuições para o ensino de física no nível médio

This study presents the results of a study on the development of the concept of force and their possible applications in physics teaching. The historical study has focused on Aristotelian natural philosophy, medieval theories of strength in impressed and on classical Newtonian mechanics. The Newtonian concept of force was also an object lesson of physics analyzed in this study. In this lesson, conducted in a preuniversity course, spontaneous conceptions or alternative conceptions of students about the concept of force proved very entrenched, resulting in studies on the Model Change on Conceptual and epistemological obstacles in view Bachelardian. The theoretical frameworks adopted led us to trace parallels between spontaneous conceptions revealed by the students and some views about the concept of force found in the study of history. The results show that while some old conceptions have been replaced by scientifically Newtonian concept of force, they are still present in the students' ideas and resist to changes even after the study of Newton's laws. Like main result shows that the history of science can be a great ally for the deconstruction of alternative conceptions, particularly when these concepts were previously presented and overcome the course of history of the development of a concept

Matemática comercial e financeira com a utilização de recursos digitais: uma experiência no ensino médio

This work aimed to investigate the possible contributions of the use of digital resources in the teaching and learning process of Commercial and Financial Mathematics concepts to high school students. Its development has included a survey of some researches on the topic as well as an experimental study of a qualitative type, in which the Webquest was used as methodology. It uses the computer, more precisely the internet resources, to assist students in building up knowledge. Eight meetings were held, in the after-school period, with a group of students of the second year of high school at a state public school in the city of Guaratinguetá. Aiming to evaluate the knowledge that students had about the theme, it was applied a diagnosis at first glance for further analysis and development of activities and interventions according to the students’ answers. Once the research data was analyzed, it was noted that the students had little knowledge regarding the basic contents of Commercial and Financial Mathematics, in addition to presenting difficulties in handling some of the digital resources used in the meetings. Nonetheless, from the students’ works, it was seen significant advances in understanding and building up knowledge on concepts such as percentage, simple and compound interest, savings, and sales involving prompt payment or in arrears

Os professores e o consumo de projetos que chegam à escola: o caso do Projeto Lego Education

O estudo proposto focaliza o modo como os professores recebem, consomem e se apropriam de projetos educativos que são implementados nas escolas de ensino fundamental. Trata-se de um estudo de caso que focaliza a implementação, iniciada em 2008, do Projeto Lego Education em escolas de uma rede municipal de ensino no interior paulista. A implementação do referido projeto insere-se em um contexto mais amplo marcado pelo crescimento de um “rentável mercado formativo” (Nóvoa, 1999) entre nós atualmente. Diante desse contexto, surge uma questão: Como foi, para os professores daquela rede de ensino, a inserção do Projeto Lego Education em seu trabalho docente e como os mesmos lidam com o projeto atualmente? Para tentar responder a essa questão o presente estudo foi realizado com os professores que foram capacitados e atuaram na implementação do projeto, a partir de entrevistas semi-estruturadas e observações. Objetivou-se investigar como o referido projeto foi apropriado (de Certeau, 1994) pelos professores na sua implementação e como os mesmos percebem o projeto atualmente. Pretendeu-se identificar, assim, maneiras pelas quais os professores relacionam-se com materiais didáticos, livros/guias do professor e cursos de capacitação docente ligados ao Projeto Lego Education, procurando caracterizar as maneiras como os mesmos se apropriam e consomem (de Certeau, 1994) tais produtos que lhes são dirigidos. Nesse estudo foi realizada também a análise de documentos relacionados ao Projeto Lego Education (sites das empresas envolvidas, manuais e revistas, entre outros materiais), focando em como esses materiais se referem ao professor e sua prática em sala de aula. A inserção nas escolas públicas de projetos que, como o LEGO, são provenientes de empresas privadas, aponta... (Resumo completo, clicar acesso eletrônico abaixo)

Espaço geográfico e educação: um estudo sobre o lugar do Conselho de Escola

In this text, the results of our research on the geographic location and establishing relationships with the School Council. We consider some legal aspects added to the evidence gathered in our experience to check how much the School Council is constituted as a non-state public place. The possibility of setting up this feature to see a meaning whose strength lies precisely in a healthy tension between the state and established community. Here is the legislation of the School Council of Suzano (SP) and some aspects of our experience from the practice of teaching at a school in Rio das Pedras (SP). We see the nature of the legal meaning assigned to this place from the study of law, considering the municipal, regional and federal levels. In the sphere of Geography use the concepts of Space, Place and City, as issues that are dear to that science. We used the concept of Topofilia to see if this particular place is the development of an individual's sense of belonging, and how it unfolds in the dynamic implications of the operation of this instrument of popular participation in the formulation of public policy education. We discussed the elements observed in these experiments to think about the composition of living environments in urban daily life

Reflexões sobre a prática pedagógica nas atividades de ensino: monitoria, no ensino médio em escola particular e estadual em Rio Claro

The difficulties related to physics teaching are related to methodology, that hinder learning, because some physical concepts beyond the common sense of most students. Just as poor training of some physics instructors in teaching is pedagogical difficulties. And also factors of infrastructure, heterogeneity in students' previous training etc.. It is proposed aim of this work to use reflection of teaching practice as a methodology. Practiced in a private school, mostly state and, in high school in Rio Claro. The method consists of preparing a daily pedagogical practice in parallel to the development of teaching, for analysis and identification of factors that result in improving the teaching of physics and physics teacher qualification

Educação do campo e ensino de ciências: Desafios e propostas a partir de princípios agroecológicos

Com o fenômeno da Revolução Verde a partir da década de 1950, o campo brasileiro sofreu grandes modificações como o incentivo a mecanização pesada e o investimento em insumos agrícolas, como fertilizantes e agrotóxicos. O processo de transformação politica e adoção do liberalismo pelo governo ditatorial incentivaram ainda mais a agricultura baseada no modelo da Revolução Verde e também fez ocasionou grandes transformações na educação. Com a redemocratização, tanto a educação como o campo, passaram a ser discutidos intensamente, no governo e nos movimentos sociais. A partir da Constituição Brasileira de 1988, foi elaborada a Lei de Diretrizes e Bases da Educação Nacional (LDBEN 9394/96) e seu artigo 28 dispõe sobre a educação do campo. Porém, somente em 2002, as escolas do campo passaram a ter uma legislação especifica, reconhecendo as particularidades da educação para camponeses. Em 2008, o Governo do Estado de São Paulo lançou a Proposta Curricular com o objetivo de organizar o sistema educacional e, com isso, todas as escolas da rede estadual seguem o mesmo currículo e material didático. O objetivo dessa pesquisa foi analisar os conteúdos do material didático destinado ao 6° ano do Ensino Fundamental da disciplina de Ciências e avaliar se esses conteúdos atendem a perspectiva da educação do campo em uma comunidade no interior de São Paulo e elaborar uma proposta de material didático complementar, embasado nos princípios da agroecologia. Este trabalho apresenta os resultados da pesquisa, realizada junto ao Movimento dos Trabalhadores Rurais Sem Terra – MST, em que se constatou que o material do governo não apresenta nenhuma especificidade ou adequação para os estudantes e escolas do campo e apresenta um material que pode contribuir para a formação desses estudantes

Um estudo sobre a implementaçã odo programa etnomatemática no contexto escolar

This research aims to present the Ethnomathematics Program, created by D'Ambrosio (1984), as a proposal for the teaching of mathematics, making it contextualized, meaningful and a program able to form critical and creative citizens, capable of transform reality. By presenting from Ethnomathematics perspective the conception of the activities, scholar curriculum and current evaluation system, a possibility of innovation on nowadays education system is opened, a system that is characterized by D'Ambrosio as obsolete. For the implementation of this proposal, a change on the teacher's attitude appears as necessary, a new attitude that makes active interferences during the learning process, and uses previous knowledge acquired by the student throughout their experiences as a starting point on teaching process. The approach between Ethnomathematics perspective and Mathematics Program provides a better opportunity for the students to construct mathematical knowledge. It is important to emphasize that the Ethnomathematics is as an interdisciplinary as a transdisciplinary program, which means that the Program is not restricted just for education and development of mathematics

Avaliação do impacto do material didático proposto pela Secretaria de Ensino do estado de São Paulo para a disciplina de Educação Física

No ano de 2008, a Secretaria do Estado de São Paulo propôs para todas as escolas estaduais o uso do material didático para todas as disciplinas, inclusive para a educação física, com proposta de atividade para o Ensino Fundamental e o Ensino Médio. Nas aulas de educação física encontram-se professores rola bola, que oferecem a bola aos alunos e não se preocupam com qualquer tipo de intervenção. Também, encontrams-se professores que procuram ampliar os conhecimentos dos alunos, aprofundando os conteúdos de educação física. Com base nisso, o objetivo deste trabalho foi avaliar o impacto do material didático na opinião dos professores do 8º ano do Ensino Fundamental. Para tanto, foram realizadas entrevistas com cinco professores, que utilizam o material didático proposto pela Secretaria do Estado de São Paulo. Após a análise dos dados, verificou-se que os professores apresentam a mesma opinião no que diz respeito ao que se deve mudar no material didático; dois professores acreditam que é possível aplicar o material na íntegra. Alguns professores afirmaram que às vezes é necessária a ajuda dos alunos na realização de algumas atividades. Outros concordam que o material chega quase sempre atrasado e isso prejudica o planejamento, atrasando o desenvolvimento dos conteúdos.

A evasão de alunos do curso de física do Campus de Guaratinguetá da UNESP

The objective the work at hand has is to discuss the dropouts of students from the major Physics in the campus of Guaratinguetá – UNESP. A survey has been made about the number of graduated and evaded students of each class since 1989, year that this course was created, until the year 2011. For this purpose, lists were collected from the section of graduation of the university, in which you will find names, year of entry, way of entry and situation of each students already enrolled in the course. Data about the dropouts of other courses of Physics at UNESP were also collected, in order to compare with the results from the unity of Guaratinguetá. Besides that, the results from researches about the lack of physics professors in the country were also taken into consideration. Some of this research sought to identify the main reasons of dropouts from the students of Physics. The data collected indicates that the dropout of this course in the campus of Guaratinguetá is higher when compared to the dropouts of others in this institution. It’s also true that the dropout rates haven’t changed significantly over the years, the average being 66.2% in the period between 1989 and 2007. However, the reason for the dropouts has changed of the years, dropouts to change for other majors increased, especially after 2005, being responsible for almost half of the dropouts in the last three years. The survey with the enrolled students of 2012 showed that this is a group of young students that don’t work and many of them have enrolled with the intension to transfer to other courses. These data contradicts the results of some researches that point out difficulties for students to reconciling work with study as one of the main causes of the dropouts. This suggests the picture in this work about the dropouts... (Complete abstract click electronic access below)

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

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

A prática pedagógica das lutas nas academias de ginástica

The fights are one of the most elementary manifestations of body culture, which are also constituted by sports, dances, games, and others. They are present in a lot of different ways, being very diverse among themselves. However, there is no consensus or agreements in the literature about the pedagogical practice of these modalities in fitness centers, sport clubs and sports centers. How do the teachers teach in these environments? What strategies do they use? How do they organize the contents? In what subjects they are based to execute the teaching and learning process? In this way, the objective of this study was to analyze some classes from different styles of fights/ martial arts teachers, trying to find what are their focus, goals, methodologies, classes’ dynamics and didactical and pedagogical procedures, aiming to check what is the focus of fights/ martial arts´ pedagogical practice in non-formal education. For this, it was selected one experienced teacher from the following modalities of fights from oriental origin: karate, judo, jiu jitsu and kung fu. The methodology used in this study consisted first in a literature review about the fights and sports pedagogy. Furthermore, there was one field research of qualitative nature, whose methods of data collection were divided in two: systematic observations of some classes of each teacher and semi-structured interviews with each teacher after the observation process, looking deeper into the pedagogical practice of these modalities. The results were analyzed through a content analyze, crossing the informations acquired with the instruments used. In addition to the description of these teachers and their classes, there was a classification of information, arriving the following categories: ritual and ceremony, tradition and discipline, didactical and pedagogical procedures ...(Complete abstract click electronic access below)

Reflexão acerca das relações de gênero e inatividade feminina nas aulas de Educação Física escolar

As aulas de Educação Física escolar apontam para um cenário recorrente e ao mesmo tempo inaceitável: a inatividade feminina. Essa realidade surge como um marco negativo, uma vez que as conquistas femininas no “universo” do movimento estão consolidadas. Entretanto, essas conquistas podem não significar uma relação de equidade entre os sexos. Baseado nisso, pretendeuse investigar a prática pedagógica de dois professores de Educação Física no trato das questões de gênero e da inatividade feminina. A pesquisa realizada teve como abordagem a metodologia qualitativa de caráter descritivo. Foram observadas aulas de Educação Física de dois professores da rede pública de ensino da cidade de Rio Claro. Após o período de observação foi aplicada uma entrevista para as meninas, a fim de dialogar sobre a problemática da relação de gênero. Para essa coleta utilizou-se um gravador de voz para registrar a entrevista, que depois foi transcrita. Como resultado observou-se que as aulas acontecem predominantemente sem a interação entre os sexos, há um domínio simbólico masculino que faz com que meninos dominem o tempo e espaço da aula. Na entrevista as meninas mostraram-se contrárias a interação com os meninos, muitas vezes por motivos físicos, sendo assim, as práticas na Educação Física escolar estão permeadas de conteúdos que exigem rendimento. Conclui-se que há carência nas aulas de Educação Física de práticas coeducativas, o que ocasiona um aumento na distância entre os sexos, descaracterizando a condição igualitária que a escola deveria proporcionar e fazendo com que os corpos femininos neguem a interação com o sexo oposto, tanto por motivos biológicos, como por razões motoras.

Um estudo sobre a resolução de problemas e suas relações com a afetividade

This research aims at examining the relationship between the performance of elementary school students Cycle I in problem solving and attitudes toward mathematics. For this, a research was conducted at a state school in the city of Bauru which was selected for convenience. Participants were randomly selected consisting of 75 students, of whom 21 were third years and 57 were of three classes of fifth year. The instruments used for data collection were: a informative questionnaire to characterize the students in age, grade, favorite subjects and the least liked, among others, an attitude scale, Likert type, to examine the attitudes toward mathematics; a interviews with 11 selected students according to scores on the attitudes and mathematical problems to be solved through the method of thinking aloud. The results showed that the major difficulties encountered by students in solving problems were: to understand the problems, formalizing the reasoning, recognize in the problem the algorithms needed for its resolution, make calculations with decimal numbers, do combinatorics, using the sum of equal portions instead of multiplying, self-confidence and autonomy in what he was doing, and others; participants with positive attitudes towards mathematics showed greater confidence to solve problems as well as a greater understanding on what was required by them, but were not detected significant relation between the attitudes and performance, since it was unfavorable

A evolução na prática da educação: o uso das mídias como ferramentas no ensino/aprendizagem da educação matemática

It is possible to note that the teaching done in the usual way goes against the language of youth today. It is essential that there be incentives and subsidies regarding the use of such media, whether the responsible government agencies and their members, be they principals and teachers, so there is a reform in the existing educational models and teaching. Currently, teaching is in a purely encyclopedic context of teaching models with pre-defined, ignoring the teaching based on the context in which the student lives (ethnomathematics). The objective of this work is to show how the use of audiovisual best known, such as newspapers, magazines, TV and computers can assist in teaching and learning of mathematics education, making teaching more enjoyable and inserted into the day-to-day student
