Estudo de sistemas com dinâmica pouco suave: brinquedos envolvendo este tipo de modelo

This work aims to study the movement periodically interrupted realized by four handmade toys. Such movement can be studied by nonlinear dynamics, but this topic is not covered in the general undergraduate courses in Physics. The study presented aim to observe, search, identify and measure physical quantities characteristic of toys according to the information provided by the dynamic, in this case, the formalism of moment of forces and energy. It also allows an approach to non-formal education in physics, since the measures and instruments differ from formal laboratory approach. These toys are unknown examples of simple machines studied in Mechanics and allow to illustrate passive walkers in Robotics

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

O desenvolvimento de habilidades argumentativas no ensino médio: perspectiva a partir de um minicurso investigativo com base na história da ciência

The performance of investigative activities with lessons in teaching Science and Chemistry has promoted meaningful learning of scientific knowledge. This study aimed to develop the links between higher education for research and skills argumentative, aimed at building the scientific concept on combustion of the candle in a closed container, for students from two classes of 3rd year of high school, two city schools Bauru, São Paulo. We decided to do a short course investigative, to respond argumentative skills which are developed during the minicourse using investigative activities, knowledge from the history and philosophy of science. The results were gathered from analysis of video recordings of episodes of the short course in both the groups, to produce a higher rate of use of argumentative skill, which were classified into categories according to the prior knowledge of the subject, 'factual knowledge' , 'understanding of concepts' and 'reasoning and analysis.' From the information obtained, it was found that both the teachers and the students were consistent in their actions, and that the activity of reasoning is key to learning. Thus, one can realize that knowledge is not acquired all at the same time, each individual depends on the mediation of the teacher in order to reach different design more appropriate teaching and investigative linked with the argument can be the key tool to acquire this knowledge

A noção de campo elétrico: reflexões de uma futura professora sobre o processo de ensino

This work offers an overview about didactic reflections in the introduction of the electrical field concept in Physics Teaching activities aimed to the High School by means of a teaching methodology based in a low cost experiment (FERREIRA E RAMOS, 2008). We analyzed the particular use of an experiment named electrostatic vector and its use in the teaching of the line force ideas, proposed by Faraday in 19th century. In the frame of this work we analyzed how this unconventional approach differs of the methodology generally presented in the didactic textbooks. We discussed that the use of low cost experiments, will not cause the student to learn, but the work of the teacher, offering an interaction between the student and the electrostatic vector, play an important role in the classroom

Experimentos de baixo custo para o ensino de eletrostática no nível fundamental

The experimentation in the teaching of physics has been extensively studied over the years because of its potential as a tool demonstration of physics phenomena studied in classroom. In such a perspective view of the action of apprentice student involving teaching future teachers of physics, under the Program PIBID CAPES, developed since 2009, seeks ways to improve the teaching of physics experiments using the theme chosen for the electrostatic work was . In this particular work, we report the development of the project in a State School located in the city of Rio Claro, in two rooms in the 9th grade in elementary school. It is planned with the activities of teaching physics at this level of education, look at how two different ways of displaying the contents of electrostatics in a playful way for elementary students and implement a library of experiments so that students can take the experiments to their homes

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

As atividades experimentais no ensino de física

This work was developed from a literature search in order to provide teachers of physics theoretical and methodological requirements for the use of experimentation in physics teaching, with the aim of contributing to the teaching practice of these teachers and, consequently, for improving teaching this discipline. Therefore, to deal in the course of this research, the goals and types of practical activities, new information and communication technologies that fit the experimental approaches and the role of the teacher in this context, specifying the variables that influence and relate with experimental activities. Studies are presented on the methodology and planning of experimental activities to draw attention to the teacher and the important issues relevant to the preparation of these activities as, for example, the proposed objectives and types of discourse and existing approaches for the conduct of practical activities. In this sense, the trend is highlighted for walks where the approach of practical activities, within the context of practices interactionist and are pointed out strengths and weaknesses of different types of activities presented. We also highlight aspects of the learning process associated with some theoretical reference that are on that subject, as Piaget, Vigotski and Ausubel, so that the teacher can apply the concepts in their theories worked in the practical lessons of physics

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

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

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

Quais relações estabelecidas entre ensino de química, educação ambiental e o enfoque CTS?: um estado da arte de alguns periódicos nacionais

This work presents results of art state that searched articles to bring in its wake the relationship between Teaching of Chemistry (TC), Environmental Education (EE) and the Teaching of Chemistry directed from the Science Technology and Society (STS) standpoint. The research was carried by articles surveying in major magazines Brazilian Environmental Education and a reference in the research magazine of Science Education, being performed a qualitative analysis of those items that were identified. It was noted that little is produced on the subject of interest within this field, in mid-1998 to June 2012. In the articles analyzed did not find a perspective that allied relationship STS and EE, or EE, STS and TC. Nine articles were found in relation EE and TC, and TC and three articles STS, constituting two thematic axes: Relationship between Environmental Education and the Teaching of Chemistry and Relationship between Science and Technology Society and Chemistry Teaching, The discussion was given from the contents that comprised the categories created. The first axis involved: a) Teacher of Chemistry and EA b) Contents of Chemistry and EE, and c) Concepts and practices of EE Chemistry teachers. The second axis of the categories are: a) formative processes and conceptions of chemistry teachers in STS: b) Analysis of TC practice focusing STS. There were works produced by the same authors, who mostly used the same theme in different magazines for publication only changing the perspective of analyzing the results. Finally, a scenario indicates that restricted thematic research and the need to advance with future work

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.
