A Compreensão da idéia do número racional e suas operações na EJA: uma forma de inclusão em sala de aula

The awareness of the difficulty which pupils, in general have in understanding the concept and operations with Rational numbers, it made to develop this study which searches to collaborate for such understanding. Our intuition was to do with that the pupils of the Education of Young and Adults, with difficulty in understanding the Rational numbers, feel included in the learning-teaching process of mathematics. It deals with a classroom research in a qualitative approach with analysis of the activities resolved for a group of pupils in classroom of a municipal school of Natal. For us elaborate such activities we accomplished the survey difficulties and obstacles that the pupils experience, when inserted in the learning-teaching process of the Rational numbers. The results indicate that the sequence of activities applied in classroom collaborated so that the pupils to overcome some impediments in the learning of this numbers

Contribuições da investigação em sala de aula para uma aprendizagem das secções cônicas com significado

In this work, the didactical possibilities of investigation use in classroom, through an experience with high school students from Federal Center of Technological Education of Paraíba, as well as the study of conic sections were analysed. In order to fulfill our goals the theoretical conceptions concerning the meaninful learning in conection with the investigation of mathematics history were taken into account. The classroom research occurred by means of activities which encouraged the learner to investigate his own concepts on the conic sections. The results of the proposed activities showed the effectiveness and the efficiency of such a methodology as regards the making up of the required knowledge. They also reveal that the investigation in the classroom guides the ones involved, in this process, to have a wider look at the origins, the methods used and the several representations presented by mathematics that certainly lead, specially the students, to a meaninful learning

Física no cotidiano: da cozinha para a sala de aula relato de uma experiência didática no município de Limoeiro do Norte (CE)

Brazilian high school teaching has passing through important changes. Based on current legislation and other official documents this research focus on the notion of contextualization, discussing the possibilities of a Physics teaching contextualized at a kitchen environment. Given the difficulties presented by students in establishing the relation between the contents discussed in classroom and their own daily lives, we propose the elaboration and application of a didactic unity. This started after the analyses of an initial questionnaire answered by the students. The didactic unity was elaborated based on an earlier proposal made by GREF (Physics Teaching Reelaboration Group) for a Thermal Physics course, and involved situations on students daily lives, in particular, those activities tried to relate formal contents discussed in classrooms to the kitchen environment. The didactic unity was applied to a public high school classroom at Limoeiro do Norte (CE). After evaluation of this experience it is possible to state that contextualization is a challenge that shall be faced, so that students may have a more critical look at physics, understanding that this subject is of relevance to all of us and is present in all world around us

Uma investigação histórica sobre os logaritmos com sugestões didáticas para a sala de aula

This study was conducted from a preliminary research to identify the conceptual and didactic approach to the logarithms given in the main textbooks adopted by the Mathematics teachers in state schools in the School of Natal, in Rio Grande do Norte. I carried out an historical investigation of the logarithms in order to reorient the math teacher to improve its educational approach this subject in the classroom. Based on the research approach I adopted a model of the log based on three concepts: the arithmetic, the geometric and algebraic-functional. The main objective of this work is to redirect the teacher for a broad and significant understanding of the content in order to overcome their difficulties in the classroom and thus realize an education that can reach the students learning. The investigative study indicated the possibility of addressing the logarithms in the classroom so transversalizante and interdisciplinary. In this regard, I point to some practical applications of this matter are fundamental in the study of natural phenomena as earthquakes, population growth, among others. These practical applications are connected, approximately, Basic Problematization Units (BPUs) to be used in the classroom. In closing, I offer some activities that helped teachers to understand and clarify the meaningful study of this topic in their teaching practice

Fontes primárias da história do vácuo e da pressão atmosférica na sala de aula: cartas e jornais históricos em articulação com o livro-texto do ensino médio

The use of the History and the Philosophy of Science (HPS) for the teaching of science and scientific subjects has been advocated in recent decades. It has been pointed out that the History of Science could make for a deeper learning of scientific concepts, since it would promote a contact with the problems which that knowledge has set out to solve. Furthermore, historical episodes would serve to put the discussions about the nature of scientific knowledge into context. With a view to explore those potentialities, the literature in the field has sought to identify the challenges and obstacles for the didactic transposition of subjects from the History of Science. Amongst many aspects, the deficiencies in the training of teachers, so that they can work with the insertion of HPS in the classroom have been highlighted. Another aspect that has been mentioned to be a challenge has to do with the didactic transposition of the Primary Sources, that is, of the original texts on the History of Science. The Primary Sources have significant potentialities: making a connection possible between scientists and concepts, showing the difficulties faced during scientific endeavors, perceiving the role of mistakes as obstacles to be surpassed, not as defeat, etc. On the other hand, there has been little exploration of these concepts in an educational context, due to their own peculiarities. The original texts are often hard to understand and their interpretation demands knowledge of the historical and scientific context in which they were written, as well as skills pertaining to the conduction of research in the field of the History of Science. With this scenario in mind, the research towards this Professional MSc degree starts from the challenge of elaborating and discussing proposals which could enable the didactical transposition of the Primary Sources. We have worked specifically with Primary Sources on the History of the Vacuum and of the Atmospheric Pressure, because of the insertion of these subjects in the Brazilian High School curriculum, in connection with the didactical textbooks. "Historic Journals" were made up from clippings of the original historical texts, as was a Didactical Unit, which takes the usual textbooks as a basis and contemplates using the Journals and the entire Primary Sources in High School. At last, we have elaborated and implemented a course designed for the preparation of teachers and for being an opportunity for the discussion of the feasibility of putting these kinds of proposal into practice

Interação em sala de aula de língua inglesa: o feedback como estratégia do desempenho assistido

This dissertation aims at characterizing the practices as well as the effects of a teacher s feedback in oral conversation interaction with students in an English Language classroom at a Primary School, 6th Grade in Açu/RN, Brazil. Therefore, this study is based on Vygotsky s (1975) and Bruner´s (1976) researches, which state that the learning process is constructed through interaction between a more experienced individual (teacher, parents and friends) and a learner who plays an active role, a re-constructor of knowledge. It is also based on Ur´s (2006) and Brookhart s (2008) studies (among other authors in Applied Linguistic) who defend that the feedback process needs to be evaluative and formative since it sets interfaces with both students autonomy and learning improvement. Our study is based on qualitative, quantitative and interpretive researches, whose natural environment (the classroom) is a direct source of data generated in this research through field observations/note-taking as well as through the transcriptions of five English classes audio taped. This study shows the following results: the teacher still seems to accept the patterns of interaction in the classroom that correspond to the IRE process (Initiation, Response, Evaluation) in behaviorist patterns: (1) he speaks and determines the turns of speech; (2) the teacher asks more questions and directs the activities most of the time; (3) the teacher´s feedback presents the following types: questioning, modeling, repeated response, praise, depreciation, positive/negative and sarcasm feedback, whose functions are to assess students' performance based on the rightness and wrongness of their responses. Thus, this implies to state that the feedback does not seem to help students improvement in terms of acquiring knowledge because of its normative effects/roles. Therefore, it is the teacher´s role to give evaluative and formative feedback to a student so that he/she should advance in the learning of the language and in the construction of knowledge

Eensino de língua portuguesa: da formação do professor à sala de aula

La reflexión crítica sobre la escuela y los quehaceres docentes ha favorecido la producción y la sistematización de nuevos saberes basados en fundamentos científicos, principalmente sobre las prácticas pedagógicas. En la enseñanza de Lengua Portuguesa, las investigaciones buscan comprender lo qué y cómo se enseña y se aprende durante la escolarización. En esa perspectiva, realizamos un estudio sobre la formación del profesor de Lengua Portuguesa y sus implicaciones en la clase, buscando observar la actuación de los alumnos-maestros en el contexto escolar, durante la realización de las Prácticas. Para tanto, elegimos como objetivo general, investigar cómo la carrera de Filología de la UFRN/CERES/Campus de Currais Novos promovía la formación de futuros profesores para atender a las expectativas de las políticas públicas para la enseñanza de Lengua Materna. Como referencial teórico, estudiamos los PCN, el proyecto político pedagógico de la carrera y autores del área de enseñanza de Lengua Portuguesa y de Educación, entre ellos, Geraldi (1996), Travaglia (1996, 2003), Antunes (2003, 2007, 2009 y 2010), Lomas (2003), Figueiredo (2005), Marcuschi (2001, 2008), Oliveira (2010), Riolfi et al. (2008), Possenti (2003), Alarcão (1996, 2001) Imbernón (2011), Pimenta y Lima (2010) y Schön (1993). El estudio está situado en el ámbito de la Lingüística Aplicada y se caracteriza como investigación cualitativa de naturaleza interpretativista, a partir de un abordaje de inspiración etnográfica del ambiente de las Prácticas. En los resultados constatamos que los alumnos-maestros privilegian la enseñanza prescriptiva, fundamentado en una concepción de lengua como sistema, direccionando la enseñanza de la lengua para la dirección contraria al abordaje funcionalista (lengua / uso), distanciándose considerablemente de la propuesta de formar un alumno crítico y agente de transformación. Respecto a la visión de los alumnos-maestros sobre la carrera, fueron listadas algunas cuestiones relevantes, entre ellas, los contenidos que hacen parte de la carrera, la distribución de la carga horaria de los componentes curriculares, la revisión de las ementas, la oferta de asignaturas de inclusión social, la reorganización de las actividades de la práctica en relación al acompañamiento y orientación a los alumnos-maestros y, especialmente, la desarticulación teoría / práctica que fue considerada como responsable por muchas de las dificultades encontradas por los referidos alumnos en la fase de regencia de clase en la enseñanza de Lengua Portuguesa en los niveles de enseñanza fundamental y media. De ese modo, a partir del análisis de estos significados construidos por los alumnos-maestros sobre el proceso de formación en esa carrera de Letras, constatamos la necesidad de una revisión del proyecto de la carrera, pues éste presenta esas fragilidades que necesitan ser analizadas en función de la mejoría de la calidad de la enseñanza de la graduación

Argumentações discentes e docente envolvendo aspectos ambientais em sala de aula: uma análise

Este trabalho trata da interação entre professor e alunos mediante a utilização do texto paradidático intitulado Nosso Universo em aulas de Física, em uma sala de Educação de Jovens e Adultos. Neste artigo é analisado um episódio que articula Ciência, Tecnologia e Sociedade aos aspectos ambientais. Esse episódio aborda o problema do efeito estufa, do buraco na camada de ozônio e da escassez da água. Para a análise, foram elaboradas categorias referentes às argumentações discentes e docente. Os resultados envolvendo o tripé professor/aluno/texto apontam que tais interações propiciaram a motivação e a formação do aluno enquanto indivíduo crítico e reflexivo, em condições de argumentar e atuar criticamente em seu meio social.

O direito ambiental na sala de aula: significados de uma prática educativa no ensino médio

Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP)

Uma abordagem dialógica para a utilização de atividades experimentais em sala de aula

The belief of using experimental activities in the teaching of Physics as a strategy to produce a more efficient teaching-learning process is great among teachers and the school community. However, there are many difficulties for their implementation and when it happens they do not contribute for an improvement in class efficiency due to the method used. In this work, we developed a proposal for using these activities in Physics classes in high school, from a critical-reflexive approach in which the constant dialogue between the participants in the teaching-learning process is fundamental. The work was developed in two ways. The first, where the author/writer created an educational material and applied it in classroom and a second one, where he presented the idea to other teachers and undergraduate students from the Physics course at UFRN and IFRN (former CEFET-RN) through an extended workshop entitled "The role of experimental activities in the Physics teaching". This workshop had the duration of 60 hours and was implemented in 4 steps: i) sensitization and formation, ii) material development, iii) material implementation and iv) evaluation by teachers and students from the classes where the material was applied. The goal of this workshop was to present the approach, evaluate how the participants received the idea and how they would apply it in real situations. The results of the application in classroom allowed us to reach some conclusions. This approach was well received by the students as well as by the workshop participants. Despite some difficulties in relation to the handling of the implementation results by the workshop participants, they indicated changes in these professionals teaching practice and the introduction of experimental activities has been an important subsidy to assist them in Physics class in high school

Os professores de química e o uso do computador em sala de aula: discussão de um processo de formação continuada

O presente artigo discute estratégias utilizadas em um processo de formação continuada que se destina a promover a inserção da informática nas aulas de Química, organizado com base na racionalidade prática e na reflexão crítica sobre o trabalho docente. Esse processo envolveu professores de escolas estaduais localizadas na região de Jaú (SP) e utilizou a educação a distância como recurso para mediar os períodos entre os encontros presenciais. As estratégias selecionadas para discussão neste artigo, dentre as utilizadas no processo de formação, são: a elaboração de material didático e o desenvolvimento de aulas nas Salas Ambiente de Informática das escolas. Tais propostas se revelaram importantes por considerarem o professor como autor dos recursos didáticos para trabalho em sala de aula, e o contexto escolar como subsídio à própria ação de formação.

Os programas de pesquisa de Lakatos: uma leitura para o entendimento da construção do conhecimento em sala de aula em situações de contradição e controvérsia

Este trabalho faz uma analogia entre os programas de pesquisa de Lakatos e a dinâmica das idéias dos estudantes em situações de sala de aula. Esta analogia revelou-se uma maneira produtiva de análise do desenvolvimento das concepções dos estudantes durante um processo de discussão. Com as condições de inteligibilidade, plausibilidade e frutibilidade de Posner et alii (1982), pudemos enriquecer a análise baseada previamente nos programas. Mostramos com um exemplo videogravado durante uma aula que a nossa abordagem pode ser efetivamente usada como um instrumento analítico para ajudar o professor a entender e melhorar os processos de ensino e de aprendizagem.

Avaliação em matemática: uma leitura de concepções e análise do vivido na sala de aula

Este artigo traz uma reflexão acerca da avaliação em Matemática, destacando os modos pelos quais essa avaliação pode vir a ser compreendida e discutida em um curso de formação de professores da área. Explicita-se como, a partir das situações de sala de aula, o olhar para as possibilidades da avaliação pode contribuir para a formação desse professor no que diz respeito ao compreendido pelos alunos. São analisadas três situações-problema, propostas aos alunos do curso de graduação em Matemática, cujo foco é o modo de avaliar. O olhar avaliativo e o fazer Matemática são entendidos como uma forma de o aluno voltar-se para o conteúdo matemático, abrindo-se ao que, no seu lidar cotidiano, se mostra. Diz-se da importância de se considerarem os dados relevantes e o a ser conhecido nas situações de avaliação que permitem, ao professor, ler a aprendizagem do aluno em seu modo de se expressar.

Da licenciatura à sala de aula: o processo de aprender a ensinar em tempos e espaços variados

Formação de professores é um desafio que ultrapassa fronteiras de espaço e tempo. No caso da formação inicial, as dificuldades de articular necessidades formativas oriundas do campo de atuação às possibilidades dos cursos que formam o professor se mantêm. Buscando contribuir para minimizá-las, realizou-se uma investigação, cujos objetivos foram: investigar processos de aprendizagem da docência e evidenciar concepções de futuros professores sobre a sua profissão. Formulou-se um questionário com perguntas abertas, respondido por vinte estudantes do último ano de licenciatura de uma universidade pública do interior paulista, de cursos distintos. Os dados foram analisados em seis eixos temáticos, resultando em significativas constatações, das quais se destaca a falta de saberes relativos à especificidade da profissão docente e ao contexto sócio-histórico no qual ela acontece, comprometendo a ação futura do professor e, consequentemente, a aprendizagem do aluno da escola básica. Cabe, pois, repensar a formação docente, numa época em que seu redimensionamento por meios tecnológicos é possível.
