Objetos de aprendizagem: limitações funcionais no ensino médio e aplicabilidade no ensino de física sob uma perpectiva vigostkiana

Neste trabalho fazemos uma revisão das novas tecnologias da informação e comunicação (TIC), definindo o que são Objetos de Aprendizagem (OA) e como eles têm sido utilizados no ensino de Física. Revisamos ainda o trabalho de Vigotski buscando indicações de sua teoria educacional para investigar a aplicabilidade de atividades didáticas em ensino de Física que lancem mão de OA no ensino médio. Elaboramos um instrumento de pesquisa voltado para professores do ensino médio para avaliar seu efetivo uso nas escolas públicas e privadas brasileiras e as limitações funcionais por eles identificadas ao utilizarem esses recursos computacionais. Com base na literatura, e sob uma ótica vigotskiana, aplicamos algumas atividades com OA pré-selecionados e avaliamos com outro instrumento de pesquisa a opinião dos alunos quanto ao seu uso para o ensino de Física. Nosso trabalho pôde corroborar a boa aceitação por parte dos alunos com relação ao seu uso, já divulgada na literatura e também por parte dos professores, mas mostrou que para além das limitações de uso dos OA, especialmente das simulações computacionais, destacadas na literatura e relacionadas às limitações cognitivas que elas podem trazer quando utilizadas de maneira indiscriminada, existem problemas mais profundos de natureza funcional que têm limitado a disseminação de seu uso efetivo pelo corpo docente.

Estudo de uma proposta de ensino de física para o primeiro ano do ensino médio inspirada na teoria do pensamento complexo de Morin

O mundo está passando por uma mudança paradigmática. O paradigma moderno baseado nas ideias de René Descartes e Isaac Newton está sendo substituído por um novo paradigma chamado de pós-moderno ou complexo. Essa mudança tem gerado uma crise em toda a sociedade, e essa crise pode ser muito bem percebida na escola. Enquanto o mundo passa a valorizar a criatividade, a autonomia e habilidades como o trabalho em equipe e a capacidade de resolução de problemas complexos, a escola procura se fechar em torno de si mesma, exigindo a memorização e reprodução de conteúdos prontos, visando a solução de problemas artificiais que em nada se relaciona com o cotidiano e os interesses dessa nova sociedade. Nessa perspectiva, esse trabalho propõe uma metodologia para o ensino do conteúdo de Física do primeiro ano do Ensino Médio inspirada na teoria do pensamento complexo de Edgar Morin. Para isso, desenvolvemos uma sequência didática com atividades que visam não só abordar os conteúdos previstos pelo Currículo Oficial do Estado de São Paulo de maneira contextualizada e motivadora, mas abordá-los com o objetivo de procurar iniciar o desenvolvimento do pensamento complexo dos alunos. Assim, para alcançar esse objetivo, na elaboração de cada atividade, levamos em consideração \"Os Sete Saberes Necessários à Educação do Futuro\" de Morin assim como as competências e habilidades que estão previstas nos Parâmetros Curriculares Nacionais (PCN). Sabemos que o pensamento complexo não se desenvolve do dia para noite, pois é um processo que se estende por toda a vida. Entretanto esperamos que com esse trabalho, possamos dar uma contribuição nesse sentido, e vislumbrar durante o ano letivo o princípio do desenvolvimento desse modo de pensar nos alunos.

O PROFESSOR DO ENSINO MÉDIO: SUA FORMAÇÃO PARA ATUAR E ENFRENTAR OS DESAFIOS DO SÉCULO XXI

Esta investigação empírica discute e analisa o trabalho docente do profissional do Ensino Médio, sua formação e desestruturação na sociedade contemporânea, procurando relacioná-la à própria crise da formação cultural em vigor. O objetivo principal é analisar as formas de adaptação e de resistência do professor perante as grandes mudanças e novas exigências para o educador do novo século iniciado no ano de 2000, com a chegada do novo milênio. A partir desse objetivo analisado, foi estudado como o professor compreende sua formação e carreira, focalizando as ações instauradas atualmente pela Secretaria do Estado da Educação de São Paulo, no período de 2000 a 2014, nas escolas de Ensino Médio do município de Barueri, confrontando com as regras propostas pela última LDB (Lei de Diretrizes e Bases) e legislação correlata também em âmbito estadual. A hipótese que rege esta investigação é a de que há inconsistências e incoerências na normatização na esfera executiva do sistema estadual de ensino. As Escolas Estaduais de Ensino Médio do município de Barueri (SP) serão o campo empírico desta pesquisa que se realizará em 2013 e 2014. A partir de informações obtidas por meio de análise documental e de respostas fornecidas por professores com questionários padronizados, objetivando caracterizar o perfil profissional do professor, confronta-lo com as exigências do sistema, identificar ações que regulam a sua seleção e explicitar sua manifestação sobre o impacto da má qualidade de sua formação no exercício da docência, fator que favorece o agravamento de forças conservadoras, cristalizadas em forma de práticas voltadas para a resolução de problemas do cotidiano escolar do Ensino Médio. Os estudos sobre cultura escolar, história da educação será apoiado Florestan Fernandes (1966), Otaíza de Oliveira Romanelli (1990), Helena Souza Patto (1999), Raquel Volpato Serbino (1998), Edgar Morin (2006), Guiomar Namo de Mello (2004), Dermeval Saviani (2003), Antônio Nóvoa (1995), José Mário P. Azanha (1968), Selma Pimenta Garrido (1992), Bernadete Gatti (1996), Francisco Imbernón (2002), Martha Abrahão Saad Lucchesi (2002), Lizete Shizue Bomura Maciel (2004), entre outros autores que estaremos pesquisando ao longo do nosso trabalho.

Abordando o sono no ensino médio: proposta de unidade didática contextualizada com o tema saúde

Biological rhythms are part of the life from the simplest to the most complex living beings. In humans, one of the most important biological rhythms is the sleep-wake cycle (SWC), which represents an indispensable behavior for health, since sleep deprivation can lead to deficits in attention and memory, mood and daytime sleepiness which may affect school performance. Nevertheless, the SWC is a content rarely discussed in schools. Thus, the aim of this research was to address contents of the sleep-wake cycle, related to the content of Health to encourage healthy sleep habits. This study was conducted in a public school with 33 students of the 3rd year of high school and is divided into four stages: 1st) Study and analysis of the content of the textbook adopted by the school to subsidize the activities covered in the teaching unit (TU) and approximation with the biology teacher from the class to evaluated the feasibility of schedules for the development of TU; 2nd) Survey of students' prior knowledge, through a questionnaire, to guide the development of the TU; 3rd) Development and implementation of a TU based on meaningful learning and characterization of the students sleep habits, 4th) Evaluation of the TU as a viable proposal to teach biological rhythms concepts. Previous knowledge of students about the SWC are scarce and this content is not covered in the books adopted by the school. Alternative conceptions were observed, particularly with regard to individual differences in sleep, which may contribute to the occurrence of inadequate sleep habits, as reported by the adolescents in this study. The activities developed during UD were well received by the students who showed participative, motivated and evaluated positively the procedures used by the researcher. After the TU, students' knowledge about the concept of biological rhythms has been increased and they started to identify that the SWC changes throughout life and occur due biological and socio-cultural factors. Thus, the UD elaborated in this study represents a viable proposal to teach the concepts of biological rhythms contextualized to the content of Health, in high school

Aprendizagem significativa: uma proposta de ensino e aprendizagem da geometria euclidiana espacial no ensino médio

This dissertation is a research based on the Meaningful Learning Theory, with students from the second year of High School, in the city named Capinzal do Norte, state of Maranhão. The pedagogic approach of this research focuses on what to do and how to do so students can better grasp knowledge inherent to the Euclidean Special Geometry in a more meaningful and changing way, also that information may be kept longer in their brain, so it can last longer in the present and future. The methodological strategy adopted was the research-action, followed by the constant observance of a researcher on the matter with the purpose to ensure consistent results, which come from the use of a variety of data collector instruments, such as: Concept Maps, manipulatives, educational softwares and application of evaluative tests, besides the observations made throughout the process of investigation and the diagnosis itself. It is all due to the fact that we rely on the premise that knowledge is assimilated in particular and idiosyncratic ways, which means each and every student learns in different ways and in different periods of time. That is why it is so important to develop diversified methodologies to the same subject. This research adds to the other ones related to the theoretical frameworks of the Meaningful Learning Theory, of Concept Maps, of the use of technology on the educational process and of manipulatives, which purpose is to connect their common dots. This pedagogical intervention also focuses on the construction of the educational orientations with applicability directly on class, directed specially by the Mathematics teacher of the basic education, who might use them during your teaching practice. Such guidelines established here as an educational product aim to follow the Theory's assumptions that serves as basis to this research, thus becoming an educational element with a relevant significance. The results, with which we are faced, proved overwhelming to the proposed objectives in terms of learning, which were evident in the construction of Conceptual Maps, as well as in the use of Concrete Materials, in addition to serving as a motivational element to participating students of research. The results obtained are indeed reliable in terms of learning, considered the expected goals, and made us certain that the way we have approached the subject is consistent with a holistic education and that at the same time values the tiniest details, which are fundamental to all the learning-teaching process.

O Ensino de ligações químicas por meio do conceito de energia: uma proposta didática para o ensino médio

This work presents discussions on the teaching of Chemical Bonds in high school and some implications of this approach in learning chemistry by students. In general, understanding how the chemicals combine to form substances and compounds, it is a key point for understanding the properties of substances and their structure. In this sense, the chemical bonds represent an extremely important issue, and their knowledge is essential for a better understanding of the changes occurring in our world. Despite these findings, it is observed that the way in which this concept is discussed in chemistry class has contributed, paradoxically, to the emergence of several alternative designs, making the understanding of the subject by students. It is believed that one of the explanations for these observations is the exclusive use of the "octet rule" as an explanatory model for the Chemical Bonds. The use of such a model over time eventually replace chemical principles that gave rise to it, transforming knowledge into a series of uninteresting rituals and even confusing for students. Based on these findings, it is deemed necessary a reformulation in the way to approach this content in the classroom, taking into account especially the fact that the explanations of the formation of substances should be based on the energy concept, which is fundamental to understanding how atoms combine. Thus, the main question of the survey and described here of the following question: Can the development of an explanatory model for the Chemical Bonds in high school based on the concept of energy and without the need to use the "octet rule"? Based on the concepts and methodologies of modeling activity, we sought the development of a teaching model was made through Teaching Units designed to give subsidies to high school teachers to address the chemical bonds through the concept of energy. Through this work it is intended to make the process of teaching and learning of Chemical Bonds content becomes more meaningful to students, developing models that contribute to the learning of this and hence other basic fundamentals of chemistry.

Transposição didática da interação do laser com sistmas biológicos no ensino médio: uma proposta de guia didático para professores

In this dissertation was elaborated an interdisciplinary didactic sequence for the development of Physical concepts involved in the interaction of laser radiation with biological matter in order to make a relation between Physics and other fields of knowledge aiming to enlarge the contextualization of scientific knowledge. The objective was to develop an educational product which theme is “Laser’s Interaction with Biological Tissues”. In this work, basic physical concepts related to laser radiation were presented, its interaction with matter and applicability in the student's daily life, with emphasis on Public Health. The inclusion of the subject in schools was effected through didactic transposition as theoretical foundation and the three pedagogical moments as teaching support. The development of the project involved discussions of scientific knowledge applied in society’s daily life. In the product's design the didactic sequence was projected and the use of varied teaching resources has been proposed, such as videos, texts, experiments, simulators and de Software “Tracker”. The construction of paradidactic material was performed considering different stages of equal importance for a teacher's reflection process. The work prioritizes the alternative conceptions of student, transforming him in a direct agent of the construction of knowledge and this aspect is based on the profile of the Student's Material. Another important point is the evaluation's proposal, this was systematized to be done class after class through building texts, essay questions, presentation of papers, among others activities. The didactic sequence guides the introduction of relevant topics of the students and society’s daily life, the ideas are not closed and in many times the teacher make changes which deem relevant to the teaching for better development of their practice.

Construções geométricas como recurso pedagógico no ensino médio

This work aims to provide high school students an development in his mathematical and geometrical knowledge, through the use of Geometric Constructions as a teaching resource in Mathematics classes. First a literature search to understand how it emerged and evolved the field of geometry was carried out and the Geometric Constructions. The ways in which the teaching of geometry happened in our country, also were studied some theories related to learning and in particular the Van Hiele theory which deals with the geometric learning also through the literature search were diagnosed. Two forms of the Geometric Constructions approach are analyzed in class: through the design of hand tools - ruler and compass - and through the computational tool - geometric software - being that we chose to approach using the ruler and compass instruments. It is proposed a workshop with nine Geometric Construction activities which was applied with a group of 3rd year of high school, the Escola de Educac¸ ˜ao B´asica Professor Anacleto Damiani in the city of Abelardo Luz, Santa Catarina. Each workshop activity includes the following topics: Activity Goals, Activity Sheet, Steps of Construction Activity Background and activity of the solution. After application of the workshop, the data were analyzed through content analysis according to three categories: Drawing Instruments, angles and their implications and Parallel and its Implications. Was observed that most of the students managed to achieve the research objectives, and had an development in their mathematical and geometrical knowledge, which can be perceived through the analysis of questionnaires administered to students, audio recordings, observations made during the workshop and especially through the improvement of the students in the development of the proposed activities.

Demonstração de fórmulas matemáticas no ensino médio

The objective of this study is to analyze the validity of working with proofs in the classroom and to present a partial list of proofs of mathematical formulae of the Brazilian secondary/high school curriculum. The adaptation of the proofs into the knowledge and abilities of a secondary school student should also be considered. How the teaching of proofs is treated in official publications in Brazil and other countries is also described. Working with proofs provides a number of benefits to the students, including: the development of logical reasoning, argumentative capacity, analytical skills on a daily basis, as well as motivation and a better understanding of mathematics as a science. The convenience of including the teaching of proofs in Brazilian secondary school curriculum and the need of a balance between the abstraction of proofs and contextualization of the school programmes is discussed. The approach of the proof teaching in the classroom can become a motivating factor or, conversely, a discouraging one. The conclusion is that it would be very useful to create a reference list covering the mathematical expressions of school programmes with their respective proofs that can be understood by secondary school students.

Manuais do professor do ensino médio: imagens discursivas de professor e de ensino de ELE

O estudo situa-se no âmbito das investigações voltadas para documentos que sistematizam o trabalho do professor, dentre eles, o manual do professor que organiza a atividade docente junto ao livro didático. A dissertação analisa manuais do professor dos livros de espanhol selecionados pelo MEC para serem distribuídos a professores, em 2005, em função da lei 11161 da obrigatoriedade do ensino da língua espanhola para o ensino médio em todo o território nacional. O objetivo foi identificar imagens discursivas de docente e de ensino de espanhol como língua estrangeira neles construídas. Os fundamentos teóricos adotados advêm da Análise do Discurso de base enunciativa, além de recorrermos aos conceitos de dialogismo (BAKHTIN, 1979) e de polifonia (BAKHTIN, 1979; DUCROT, 1987). Os resultados nesses manuais apontam para a construção de imagens de professor como: aquele que necessita ser guiado em sua tarefa, incapaz de realizar suas escolhas em sala de aula, um professor recebedor de ordens; desatualizado com as metodologias de ensino atuais, necessitando, portanto, de atualização profissional; há ainda um professor que busca instruções facilitadoras para seu trabalho. Já no que se refere à visão de língua, deparamo-nos com um manual que dá ênfase ao trabalho com a leitura, voltado para uma concepção que valoriza aspectos discursivos; outros que afirmam seguir a abordagem comunicativa, com um olhar para a língua em uso, porém adotam procedimentos pautados numa concepção de língua como estrutura e/ou misturam ambas perspectivas
