Formação de palhada por braquiárias para adoção do sistema plantio direto

Com o objetivo de avaliar espécies forrageiras para formação de palhada para adoção do sistema plantio direto, foi pesquisado o potencial de Brachiaria decumbens e B. brizantha, comparadas ao milheto (Pennisetum glaucum). As plantas de cobertura foram semeadas em março e conduzidas até novembro (momento do manejo químico). Aos 50, 110 e 250 dias após a semeadura (DAS) foram avaliadas a composição específica das infestantes na cobertura vegetal, a porcentagem visual de cobertura do solo e o acúmulo de massa vegetal seca das coberturas. As braquiárias foram eficientes na formação de palha (acima de 11 tha-1), sendo promissoras para o sistema plantio direto. Também, observou-se densa cobertura do solo, com supressão do desenvolvimento de plantas daninhas, o que não se percebeu com milheto, cujo maior potencial de cobertura do solo e acúmulo (10,5 t ha-1) de massa ocorreu no fim do seu ciclo (110 DAS) e, 3,2 t ha-1 de massa vegetal seca aos 250 DAS. Devido à rápida decomposição da palha de milheto observou-se, também, reinfestação da área por plantas daninhas.

Espaços transversais em educação matemática :uma contribuição para a formação de professores na perspectiva etnomatemática

This PH.D. thesis is an attempt to show the beginning, evolution and unfolding of the making of a pedagogical work proposal based on culturally-built knowings in the heart of a traditional community, having as one of its starting points the knowings and doings experienced by dish-making women from Maruanum living in the city of Macapá, State of Amapá, Brazil. This proposal is strongly associated with the need we have to think about the nature of (ethnological)-mathematical knowledge generated by particular communities and about the way such knowledge can be discussed, worked out, and validated in learning environments, regardless of the level of instruction and the constraints imposed by government programs and educational institutions. Among its theoretical foundations are studies on instrumental activities that are typical of the Maruanum ceramics and investigative studies from the point of view of ethnomathematics. Methodological development took place with the application of activities, where traditional and instrumental knowledge observed in the production of ceramics had been adapted for and brought into the school environment , participative observation, as well as data collecting and organization techniques, such as interviews, statements, and audio an visual recordings. Analysis of the data collected focused on the relationship between the data-generating potential and the purpose of this study. Our aim is to make and estimate of the potential contributions from local situations and/or problems it would possibly bring to the formative learning of people involved in the educational processes of these communities, with a view to a spatial and temporal transformation of reality

Representações sociais de formação continuada: com a palavra as professoras do ensino fundamental da rede pública de Natal RN

Metaphorically, research is presented as a journey by sea, having as object of study the social representations of Continuing Education for teachers of elementary school and as aim, to analyze them in comparison of participants from state and municipal systems, located in Natal-RN, Brazil .They have contributed to the achievement of this objective the voices of 158 teachers, the vast literature on training in professional development and the theoretical formulations proposed by Moscovici and colleagues, with relevance to the Central Nucleus Theory advocated by Abric. The corpus resulting from evocations about continuing education, as well as teachers' justifications were submitted to different computer methods/techniques, through the EVOC ALCESTE Programs, respectively, providing the opportunity to highlight a network of interconnections between the likely core and the production of discourse. Although the educational ideologies that underlie social perception of the state teachers are anchored in New School and technicist concepts and the teachers in the city tend to an ideology of social interaction, the choice of working with the symbolic field identified the political-social commitment of groups with the impacts of training on learning of their students

Pedagogia Freinet :mediação para o social, o político e a formação de professores

Ce projet présente dans son premier chapitre une étude historique-bibliographique basée sur la Pédagogie Freinet en France, ainsi que sa formation républicaine, ses courants politiques et idéologiques qui ont moulés l organisation sociale et éducationnelle de ce pays. Ce travail montre le rôle des courants de gauche dans ce processus, cela se reflète aussi sur le jeune Freinet. Les changements opérés dans la décennie de 1950 dans le système scolaire, dans le propre Mouvement Freinet et les ruptures qui ont eues à l intérieur de ce mouvement.

Le deuxième chapitre aborde la reconstitution historique du Brésil dont sa phase coloniale et impériale. Les événements historiques de la IIIe, IVe et Ve République sont mis en relief avec ceux du Mouvement Freinet. La phase militaire imposée au Brésil et les luttes pour la reconquête de la démocratie. Il se termine avec les considérations sur la LDBEN 9394/96 et l implantation du Curso Normal Superior; un bref historique de la Pédagogie Freinet au Brésil, des thèmes importants travaillés dans le troisième chapitre. Dans ce chapitre une recherche qualitative est décrite basée dans l Etnographie Critique et Multiréférentiellel et aussi dans la Recherche-Action. Elle est développée auprès d un groupe de cinq professeurs des premières classes de l école primaire au collège, inscrites dans le Curso Normal Superior. Les données ont été obtenues à partir de rencontres régulières avec le groupe la médiation didactique , des entretiens, des questionnaires, des observations dans les salles de classe, du travail final du cours, nommé Mémorial de Formation. À travers l ensemble des données, on recherche les apports et l actualité d une proposition pédagogique historiquement firmée pour le développement de la praxis éducative

O percurso da ressignificação de si : do esporte à formação do professor de dança

The present work is characterized as a research-formation study. The author analyses his trajectory as dance professor, observing processes of transition in the perception of the body: from the mechanical body to the sensitive body. He tries to outstand this new meaning of the body and the dance teaching and artistic experience as the matter that instructs itself. This research puts together the experience of two teachers, one of them as student (researcher), while the other, as master and professor (collaborator) and intends to comprehend how this new meaning of the body was brought to each one s life, motivated by the dance. It is used the self biographic method and the research-formation methodology to analyze and identify common points between their self formation processes. The researcher and collaborator life narratives as well as a partially structured interview with the collaborator were used as investigation source. The analysis followed the models suggested by Schütze (1977), presented by Bauer and Jovchelovitch (2004), guided by the five pillars of the study: the Subject aspect, as guiding point for the analysis; Corporal aspect, as component and integrant element of an individual and of the dance; the Dance while seen as forming and guiding practice for the individuals researched; the Complexity aspect; and finally the Instructor and Professional Formation, emphasizing the self formation process. The results showed how the dance has changed their perception of their own bodies and the whole corporal aspect, leading to subject-actor body point of view, and no longer from a strictly mechanic perspective. The teaching trajectory was defined by the new evaluation of the body through the Dance bringing the individuals researched to a dialogical-reflexive teaching practice that motivates self consciousness, humanization and automatization, in the context of their background experiences and the environment they act

Possibilidades de exploração da história da ciência na formação do professor de matemática: mobilizando saberes a partir da obra de Nicolau Copérnico de revolutionibus orbium coelestium

This study aims to analyze the implications that the knowledge of an important work for the History of Science, De revolutionibus orbium coelestium , by Nicholas Copernicus, can bring for the formation of Mathematics professors. The study focuses on Book I of Copernicus s work, where, in the final part, is found the Table of the Subtense Straight Lines in a Circle, a true sine table constructed by the author. The study considers two theoretical references, the History of Science and of Mathematics, in the professor s formation searched amongst others in Miguel and Miorm, Brito, Neves and Martins, and Radford, and the necessary teaching knowledge professors mst have, on the basis of Gauthier, Schulman and Imbernón amongst others, through which it is established a net of knowledge grouped in dimensions such as mathematical, psycho pedagogical, cultural and practical diversity, that guide the study analysis. In the search for more necessary elements to enrich the analysis, beyond the theoretical research in Book I, it is carried through, with under graduation pupils, future Math professors, the construction of a sine table following the project used in De revolutionibus . The study still makes a description of the life and work of Nicholas Copernicus, detaching the historical context where the author lived and the conceptions about the Universe existing at that time. The research reveals that the studied work is an important source of culture, able to provide to the Mathematics professor in formation, beyond the conceptual and procedural mathematical knowledge, a cultural knowledge that allows him to be opened to the knowledge of other areas that not his specific area, and so to acquire knowledge about the world history, the development of sciences and of the society

Concepções de alunos do Curso de Pedagogia da UFRN acerca da natureza da ciência: subsídios à formação de professores

En el campo de la Educación en Ciencias, los estudios acerca de las concepciones de profesores sobre la naturaleza de la ciencia están en crecimiento en las últimas décadas en virtud de la importancia atribuida al saber sobre las ciencias. Manifestando preocupación con la temática, los trabajos de esta línea de pesquisa están investigando concepciones de profesores en formación como también los en ejercicio. Inserido en esa problemática, y preocupado con la formación inicial de profesores, este trabajo tuvo como objetivo principal investigar las concepciones de los alumnos de la Carrera de Pedagogía de UFRN (Universidad Federal de Rio Grande do Norte) acerca de la naturaleza de la ciencia, una vez que los alumnos son, o lo serán, profesores que darán clases de ciencia. El aporte teórico del estudio fue el abordaje ofrecido por la filosofía de la ciencia contemporánea, como también trabajos de literatura especializada sobre la temática NdC (Naturaleza de la Ciencia). En la parte empírica del trabajo utilizamos, como principal instrumento de colecta de datos, un cuestionario abierto, en el cual los alumnos marcaron posiciones sobre varios aspectos de la naturaleza de la ciencia. Fueron sujetos de la investigación 81 alumnos de Pedagogía, que estaban en el primer, quinto y noveno semestres (también dichos períodos ). Los resultados presentaron un acercamiento a las concepciones de los sujetos sobre la temática, indicando la presencia de una serie de concepciones poco satisfactorias de la ciencia, al lado de concepciones más consistentes con la epistemología contemporánea. En el comparativo entre los grupos, el quinto semestre presentó resultados un poco mejores que los demás, trayendo a la superficie elementos para evaluar el impacto de la formación en la construcción de las concepciones de ciencia por los alumnos

Da formação ludopiética à autopoiese do lazer: significados para a autoformação humanescente do profissional do lazer

The present study aimed to understand and interpret the connections between the training of graduate ludopoiética leisure and the process of autopoiesis of leisure. From the main objective, the following objectives had been formulated specific: a) To interpret more significant the ludopoiéticas experiences in the academic formation of graduandos of leisure; b) To analyze the experiences of the leisure most significant, disclosed for the group investigated, before, during and after the course; c) To describe and to interpret the process of autopoiese of the leisure and its respective meaning for the autoformação human being. The study it articulated the following metodológicas boardings: autobiogr á fica, etnogr á fica and fenomenológica. For the construction of the ludopoiéticas bridges between the academic formation proposal for the course of Leisure and Quality of Life of the CEFET-RN and the autoformação lived deeply human being as leisure for the participants of the study, we use as categories of analysis, five properties that had constituted the respective autopoiético system of the leisure. Thus, for our autopoiética reflectivity we adopt the following categories: autotelia; autoliberação; autoconectividade; autovalia and autofruição. The carried through research obtained to evidence given important of the ludopoié tica formation of these professionals of the leisure for its autoforma ç ã o human being and the autocriação of the proper leisure, that for recursividade feeds this autoformação in way permanently. Lived deeply properties of the ludopoiético system in the formation are searched with autonomy in the leisure. Thus, the learning of the autotelia, the autovalia, the autofruição and the autoconectividade lived deeply during the course of graduation in Leisure and Quality of Life is valued by the emotion of the joy and the love to the life, having become something desired by the citizens that had chosen the leisure as profession

Dificuldade de berço? Professores de matemática no ensino médio: práticas, formação continuada e juventude

The present paper is focused on pedagogical practices and continued lecturing formation of High School Mathematic teachers. Knowing the essential importance of the teacher at the educational process since he/she is the mediator on knowledge gathering by the scholars and continued formation meaning on that process, we hereby propose to investigate and compare what Math teachers think about their professional role, the kind of continued formation they receive and their development on teacher s knowledge and doing; to gather and compare what do Math teachers know about young people at public and private schools and their demands and as which find out if they link with the way as their students are taught. To develop our comparative research, we chose a qualitative focus and an investigation of ethnographic type. We took as the subject four Math teachers that work with high school 1st and 2nd grades in public and private schools, morning and afternoon shifts and license titles. The research results reveal differences in structural matter between the spaces, but the comparisons between teacher doings and knowledge reveal that the differences refer to the sort of formation and how often do the teachers search for it. Nevertheless, the reports pointed to continued lecturing formation offering and consistence problems and these reflect on their work and on its basis. The knowledge about youth and adolescence, such as theoric and methodological knowledge that lead their practices, are revealers of teachers difficulties in developing their activities according to the target public and nowadays educational demands

O lugar pedagógico da educação física na educação infantil: saberes (re)construídos na formação continuada do PAIDÉIA/UFRN

The present study aimed to investigate the overview of teachers in continuing education program who work in kindergarten, about the continuing education developed by the Paideia/UFRN through the Course of Specialization in Art Teaching and Physical Education in Childhood, having as key focus, the knowing / doing related to physical education in Childhood. From this general goal, it was elected some specific objectives as: to know the interests and expectations that motivated the teachers to participate of that referred training; the evaluation by teachers on regard of the continuing education proposed: boosters factors for possible changes in teaching activities regarding the practice of teaching physical education in kindergarten. The methodology took the principles and techniques of qualitative research strategy and the characteristics of descriptive and interpretive strategy. The locus of this research was the Course of Specialization in Art Education and Physical Education in childhood, having as the citizens of this research twenty three teachers taking that specialization course. For building and systematization of the data, we used the following tools and procedures: a questionnaire, a semi structured interview and documents analysis. The data was constructed based on the technique of content analysis, focusing the reflections and speech of the teachers about the creation of new meanings and senses for the knowing / doing in Physical Education. It was found, among other results, the need and quest for improvement of teacher education, in order to improve educational practice. It was also evident that the situations of dialogues (interactions with peers, with their professors and other professionals in the related area or not) were mentioned by most teachers in the course as a relevant moment of redefinition of knowledge. In relation to Physical Education, it was found that participation in the course of specialization provided the recognition of teaching practice of physical education as part of the curriculum and the importance of inclusion of its specificities in their educational planning. From these elaborations, we come to the conclusion that knowing the perspectives of the teachers about continuing education can contribute to the theoretical and methodological discussions in teachers education and the creation of new actions - projects and programs of continuing education constructing increasingly ways towards a successful teacher formation, able to provide new forms of acting in the educational context

Humor gráfico: o sorriso pensante e a formação do leitor

This research investigates the graphic humor, in particular the political cartoon and the cartoon, texts characterized by mixing visual-oral language, and its contribution in the formation of the reader. Recovers the main theories about the comicality in general and verifies the presence of these concepts into the texts of graphic humor and how they articulate themselves within the process of seducing the reader. Grounded in the studies of Umberto Eco about the cultural industry products and its relations with the literary theories and the aesthetics reception. After analysing texts of graphic humor, the study concludes that the triad, image-word-humor reveal a sophisticated arrangement which allows the reader to practice effectively the political cartoons and cartoons of production, of sense, cooperating in such a singular manner to the formation of a reflexive reader

A participação dos sujeitos e a reflexão coletiva das práticas na formação docente

Cet article propose, à partir d'une analyse de trois expériences différentes de la formation des enseignants, voir la pratique de l'enseignant comme une réalité et la comprendre, dans cette perspective, dynamique, génératrice de contenu et possible d être transformée. Une étude menée par un groupe de chercheurs de Sao Paulo do Potengi / RN avec des enseignants des écoles municipales dans les années 70, la mise en oeuvre du projet de réorientation curriculaire par le Bureau d Éducation de la ville de São Paulo - SP en 1989, et le cours Pédagogie de la Terre à l UFRN créée en 2002 sont pris en compte dans ce travail, comme des références dans la formation des enseignants qui démontrent à la fois les référentiel théorique et les actions développées sur la pertinence des réflexions par rapport à l'enseignement pratique comme point de départ quand on cherche à transformer l'école. Du matériel de lecture sur la manière dont ces processus de formation des événements a été possible de détecter la présence de deux éléments qui semblent être importants: la participation des personnes concernées et le reflet de leurs pratiques. Nous avons cherché à comprendre comment ces éléments apparaissent dans la pratique de deux étudiants du cours de Pédagogie de la Terre au cours de leurs classes de stage, en cherchant à identifier la façon dont ils font avancer ce point de vue de ce qui se passe dans le processus de formation. L'étude fait remarquer que la participation des sujets comme la réflexion collective des pratiques peuvent être cruciale pour la compréhension d'un enseignement qui peut être dynamique et de transformation des sujets, et qu elle peut se passer dans un processus de construction collective du savoir marquée par une refléxion et d une manière critique de faire et réflexive d'elle-même dans l'autonomie scolaire, améliorer la qualité de l'enseignement et le renforcement de l'enseignant et de l'élève comme des sujets actifs dans la reconstruction de leurs connaissances

Luta pela terra, luta pela palavra: história de vida e formação de duas educadoras populares do campo

This project has resulted from a reunion between me and two teachers with whom I had already worked, pedagogically counseling them during the execution of the Project of Youngsters and Adults Schooling at the Agrarian Reform Settlements in the State of Sergipe (PAJA/PRONERA) between 2002 and 2003. The matter that really motivated the research was related to the essential principle that guided the accomplishment of the PAJA s teachers education and professionalization: understanding their reality and knowing their needs, promoting the dialogue between scientific and common sense knowledge. Taking as a reference the fact that the teachers education is not restricted to the academic qualification, that is, that it is a part of the educational process, which, in turn, is a result of each one s personal background, dialectically individual and collective, the access to the teachers reality and needs was accomplished by studying their backgrounds, especially their school and professional career. They, inevitably, focused themselves on the country life s social and cultural context, that could be better understood by living together with the teachers during the twenty-seven days I stayed in the Golfo s settlement, located in the town named Pacatuba/SE. The approach to the teachers lives through their stories and the daily contact proved how much Science is still distant from the peasants routine, sometimes being presented to them as a finished product . That way, the dialog between those two categories and the expectation of the country life s social and cultural conditions, together with the education, in which teachers have an essential role, still remain as a challenge

Entre telas, diálogos e estratégias: formação docente para a mídia televisiva

Cette recherche à comme but montrer l'importance de la formation des enseignants pour la média télévisive.

Il croit à une possible spécificité de la formation des enseignants pour l'utilisation critique de la média télévisive, en considérant le potentiel créatif de l'enseignant, le contexte personnel et de la performance professionnelle, leurs expériences avec les médias de télévision, ainsi que celles des étudiants, et la capacité de réfléchir sur la pratique, et c'est ça la thèse de cette recherche

Como vão se formando os professores em física e química: embates entre o ser, o ter e o fazer na formação de licenciandos da UFRN sob a perspectiva da teoria das representações sociais

The purpose of this work is to approach and understand the Social Representations (SR) (MOSCOVICI, 2003) about Physics and Chemistry from people who are major in these courses, as well as their Social Representations about teaching . We took as principle that approaching these representations it would be possible to relate their symbolic contents, in order to show how people who are following the first segments of bachelor degree courses in Physics and Chemistry become teachers, taking into account a psychosocial view. Two source of data was used during this research: Free-association Technique FA (ABRIC, 1994); and Multiple Classification Procedure (MCP) (ROAZZI, 1995). The analytical treatment of the collected data from FA was done according to the proposition of Grize, Vergés and Silem (1987 apud ABRIC, 1994, p. 66). MCP data were analyzed through MSA (Multidimensional Scalogram Analysis) and SSA (Singular Spectrum Analysis) methods associated with the Facet Theory (BILSKY, 2003). The discourses of MCP discussing groups at the moment of explanations were studied by Content Analysis as it was proposed by Bardin (1977) and Franco (2005). Indicative of an approach to the relations with knowledge (CHARLOT, 2000), the connections which aroused from the analyses showed that the group of future majors in Physics thought that this scientific field was based on a rationalist conception, influencing the idealization sense of the phenomena to be explained by Physics. Thus, Physics as school content started to require the student of the fundamental and high school to think abstractly as a cognitive skill of learning. The identifying elements observed in the relations between SR about Physics and Teaching aroused from the antagonism between future majors and their teacher, as well as from the speculation between their fundamental and high school students and themselves, mainly when they had to face the act of teaching due to the obstacles imposed by the own educational system, and by the weakness of the initial preparation. The group of future majors in Chemistry, through its discourses, showed these relations when they conceived empiricist Chemistry and said that teaching was the way of transmission of this knowledge, and didactics of Chemistry teaching was the direction to learning through pedagogic methods in order to lead the students to discoveries. The psychosocial contents which were built and showed from the symbolic relations in the studied SR achieved the relation of identity. This relation revealed identifying elements for these people, resulting from the traffic between their condition as students of Chemistry, and as teachers regarding their work, what placed the current relational contents in the teaching space, named as Knowledge changing and Adaptability . In order to study emerging questions in the discussing environment about formation and teaching professionalization, we focused the psychosocial view on this traffic and managed to observe epistemological practical and pedagogic obstacles that limited a configuration of the teaching work as a professional activity, especially from the particular conditions which led the relations of senses to Physics , Chemistry and Teaching ; and Chemistry and Physics as it was seen in this research. Generally speaking, we noted that these obstacles can denounce such obstacles concerning to the pedagogic doings which mainly impair the learning process of fundamental and high school students
