A educação física no ensino médio em escolas particulares: as perspectivas de alunos, diretores, coordenadores e professores de educação física

Although physical education is regulated by law and recognized as a mandatory component of basic education class, which includes high school, there are many reports that these classes do not actually happen. Such evidence shows the situation experienced by the author of this study, which brought this research to the attention. Therefore, the objective was to investigate and understand the perspective of students, physical education teachers, principals and coordinators forward their ideas to this reality, about the high school physical education in private schools. The research made use of qualitative approach, guided by an exploratory study. The technique was undertaken to collect the questionnaire with open and closed questions, involving 263 students enrolled in high school of four schools in two cities in the state of Sao Paulo and also the director, coordinator and professor of physical education of each one of these institutions, resulting in 12 education professionals. The categories of analysis were defined as: 1. Regarding physical education in high school, 2. The occurrence of physical rducation in high school, 3. Content and dynamic strategies developed in class 4. Student participation in class. The results show that despite, although some schools have physical education classes, there are still many students who do not take them. This reveals a double challenge to the area, which is: although it is essential that such a curriculum component is included in the grades (respecting the regional law legal system) that is not enough students that actually participate in it. As teachers, coordinators and directors recognize the importance of effective physical education, there are numerous of factors that deserve consideration to better understand this reality. One relates to the content of sportivization, another contrast to the period of occurrence of classes in relation to other curriculum components. Additionally, some others are relat...

O tratamento probabilístico da teoria cinética de colisões em livros de química brasileiros para o ensino médio

This paper presents and discusses an analysis of the approaches and the didactic treatment of the kinetic model of collision between particles in chemical reaction (collision theory model) presented by brazilian chemistry textbooks for the medium level. Our starting point at this search was the correct and scientific model for this theory which is based on random events, but most of all the books investigated does not consider this fact like an important and very precious didactic aspect. We utilized in the investigation the writing discoursive analysis technique.

As mudanças procedimentais de alunos do ensino médio durante o trabalho com investigação matemática em sala de aula

The paper that if presents, tells a research carried through next to students of the High School, in which activities of mathematical investigation from questions of some examinations of federal and state public universities had been elaborated; later applied to these students in a state school of the inside of São Paulo and with data obtained from their productions, we search to analyze which procedures had been used for them and which procedural changes had occurred. It is intended with this, to collaborate for the mathematical formation of the students of High School aiming at a more significant learning of the mathematical concepts and the procedures involved when working with this type of activity.

O conhecimento biológico nos documentos curriculares nacionais do ensino médio: uma análise histórico-filosófica a partir dos estatutos da biologia

We analyzed the National Curriculum for Secondary Schools with respect to the ontological, epistemological, historical, social and conceptual biology. This study aims to bring information and thinking about the inclusion of history and philosophy of biology for secondary education and for teacher training. We performed an analysis of PCNEM, PCNEM+ and Curriculum Guidelines as a whole from established categories. The results indicate a predominance of the ontological view of mechanistic biology. Epistemologically, although acknowledged, the question of scientific method is rarely discussed. The historical approach and social scientific activity and scientific knowledge are recognized by the documents, but an instrumental view prevails. The conceptual aspects are comprehensive and take into account the theories of structural biology. A philosophical discussion on the biology is missing in the parameters, indicating the need for the inclusion of issues related to ideas of determinism, chance and teleology.

Física Moderna e Contemporânea no ensino médio e a formação de professores: desencontros com a ação comunicativa e a ação dialógica emancipatórias

Taking into consideration various argumentation perspectives, the introduction of Modern and Contemporary Physics at High School level has been defended by various researchers. In the present qualitative nature research, we heard and interpreted ten High School physics teachers’ discourses, aiming to analyze how their initial education, regarding to Modern and Contemporary Physics, was based in a rationality which matches with the communicative and the dialogical actions. Teachers of our sample were individually interviewed and, at that time, they had finished their initial undergraduate program at least five years before. Teachers’ discourses interpretation was supported by some French school discourse analysis’ concepts, Jürgen Habermas’ communicative action, Freire’s dialogical action, as well as teachers’ education research critical referential. The discourses interpretations evidenced that these teachers’ education, with respect to Modern and Contemporary Physics, was mainly based in technical-instrumental rationality basis. This perspective did not help teachers’ autonomy construction in order to work these subjects in their classes, mainly in a perspective coherent with the teachers’ emancipation, producing reflexes in classroom physics teaching. The study evidenciates the necessity of future teachers’ professors revise theirs teaching practice, as well studying other curricular structures, regarding to Modern and Contemporary Physics teaching.

Representatividade das redes sociais no processo educacional: potencialidades dos grupos virtuais como ferramentas de ensino-aprendizagem no Ensino Médio

One tool that has been in evidence, especially among young people, is Facebook. It can be classified as a synchronous communication tool that allows communities of people with similar interests to discuss and exchange experiences in real time, promoting the sharing of information and the creation of collective knowledge, even if they being in different parts of the globe. In this paper we show that Facebook can be used as an educational tool to aid the work done in the classroom and the impact of creating closed groups in online social networking for educational purposes. The survey was conducted with a group of students at a private school in Bauru/SP. We investigated the interaction profile of students with a closed group created on Facebook and through a questionnaire analyzed whether students use virtual environments for personal or educational. The survey reveals students perceptions about relevant aspects and the potential use of this tool as teaching-learning strategy

Qual a maior contribuição do ensino de ciências à sociedade? O que revelam professores da educação infantil ao ensino médio

Este estudo teve como objetivo mapear as concepções de professores de diferentes níveis de ensino sobre a maior contribuição do Ensino de Ciências para a sociedade. A proposta faz parte de uma pesquisa realizada pelo grupo de pesquisa Formação e Ação de Professores de Ciências e de Educadores Ambientais. Os dados foram coletados por meio de uma questão contida em um questionário, com 75 professores. As respostas foram organizadas em categorias relacionadas: à maior contribuição, às características envolvidas e ao elemento objeto da contribuição. Os professores revelam aproximação com discurso hegemônico e distanciamento das perspectivas críticas, indicando a necessidade de problematização da perspectiva política–pedagógica dos professores de Ciências Biológicas.

Concepções de alunos do ensino médio sobre o tema água: subsídios para o planejamento de atividades investigativas interdisciplinares

Meaningful learning occurs when new knowledge to be aggregated are grounded in other students already possess. In preparing didactic sequences for teaching concepts, one should take into account these concepts and knowledge to produce more effective and lasting learning, and build new concepts that will become subsumes for subsequent learning. This research was developed in a subproject linked to institutional Scholarship Program Initiation to Teaching (PIBID) of a Universidade Estadual Paulista. The proposal is based on the articulation of the Public School and the University, strengthening the initial training of undergraduates, and continued teacher network, improving the quality of education. The proposed work is based on interdisciplinary research and teaching by investigation. Undergraduates in Biology, Physics, Mathematics and Chemistry jointly propose interdisciplinary teaching activities and investigative applied to high school students of Public School partner. To survey the views of these students on the theme Water, they were asked to draw up an essay entitled "The importance of water", with the aim of organizing information for planning a teaching strategy that articulates the disciplines of training of undergraduates. In this paper we present a qualitative analysis of these essays, performed based on content analysis. The analysis allowed to identify existing concepts in students' cognitive structure and classify them into adequate and inadequate compared to scientifically accepted concepts. Several misconceptions were raised indicating the need to produce didactic sequences that in addition to working the concepts presented in the curriculum of disciplines take into consideration the possibility of more meaningful learning. This research produced the elucidation of existing concepts, indicating where deficiencies were larger. One major contribution was the realization that concepts that may be considered by teachers as simple and already acquired by the students often come so misguided in their explanations. From the results obtained, integrated activities have been planned and implemented, and more relevant to the needs of students aiming to recover and enrich the knowledge they possessed, encouraging the use of scientific concepts and their application to daily living situations.

Vulnerabilidade ao HIV em estudantes de ensino médio de uma escola pública do interior de São Paulo

Introduction: sexuality is an inherent dimension in the human being, which is present in all stages of his development. However, it becomes relevant during the adolescence as it often sets the beginning of the individuals` sexual life. Objective: this study aimed at identifying the behaviors of adolescents regarding the HIV vulnerability, considering the differences between genders. Methods: it was used a structured questionnaire proposed by the Ministry of Health and Ministry of Education of Brazil with the title “Do I need to text for HIV?” Sample included 136 high school students in the inner state of São Paulo. Results: the results showed an increase in adolescents’ vulnerability to HIV, that is: 59.5% of the participants are in a vulnerable situation. Regarding the gender, research showed that women (33.1%) are more vulnerable than men (26.5%). Conclusion: it is observed that the lack of information is a reality that increases the vulnerability of adolescents, but it is also observed that the mere acquisition of information does not necessarily guarantee behavior change nor HIV prevention.
