Reelaborando conceitos e ressignificando a prática na educação infantil

In this research we described the path of thirty one teachers involved with elementary school, amog which we included ourselves, looking for professional formation that allowed us to understand the function of educating childen. In this sense, this group of teachers begins a process of intentional, systematic and voluntary reflection, in an attempt to give new meanings to daily concepts of life and work, and linking them to their socialpractices. Having as reference the theoretical and methodological principles of socio-historical approach and collaborative research, the Group of Studies: The Dialogue Reflection as Re-meaning of Pedagogical Practice: a continuous education proposal, motivated by the willing and the necessity of re- elaborate knowledge about collaboration, reflection, infant education, playing and development which meets the new and goes the inverse way revisiting concepts and conception already consolidated, confronting and re-meaning them enlightened by one s own effort and the collaboration of pairs, mediated by Cycles of Reflexive Studies and Inter/intrapersonal Sessions. We can affirm that these tools helped the process of reflexivity put into practice by participants, which most important consequence was the theoretical re-meaning and practice in the ambit of infant education. During this investigation, we could see some theoretical and practice presuppositions which permitted to attribute to the exercise of reflexivity in collaboration the means into which the involved people could rescue the actions taken, justified their choices, confronted their theoretical options with their peers and with the systematized knowledge would question their certainties and rebuild in intra-psychological level, the knowledge elaborated socially. To this group which main activity is the docent profession, the personal and professional development constitutes the objective in which actions were articulated and operations which made learning possible as well as professional development

O processo de aprendizagem de professores do ensino fundamental: apropriação da habilidade de planejar situações de ensino de conceitos

La investigación fue realizada con profesores de los años iniciales de la enseñanza básica, alumnos de la carrera de Pedagogía Licenciatura Plena del PROBÁSICA de Ceará-Mirim (RN). Tuvo como objetivo general el estudio de lo proceso de apropiación de esa habilidad, segundo las siguientes perspectivas teóricas: históricocultural, de L.S. Vygotsky, teoría de la actividad, de A.N. Leontiev, y la teoría de la asimilación por etapas mentales, de P. Ya Galperin. La metodología se desarrolló organizándose en tres etapas: el diagnóstico inicial, con el análisis del nivel de desarrollo de la habilidad de los profesores; el proceso formativo, con la orientación del aprendizaje, el control y la evaluación del desarrollo; y el diagnóstico final, con el análisis del nivel alcanzado en la experiencia. Los instrumentos utilizados fueron: un cuestionario, para la caracterización de los sujetos de la investigación, el planeamiento de enseñanza de los profesores y el diario de clase, donde se registraba lo que ocurrió en cada orientación y realización del proceso formativo. Los resultados referentes a los niveles iniciales del desarrollo de la habilidad han revelado un grado de espontaneidad en el planeamiento de enseñanza de los conceptos. Durante el proceso de enseñanza y aprendizaje, los profesores han expresado sus dificultades, pero también las posibilidades de mudanza para que alcanzaran un nuevo nivel de desarrollo. Para el análisis del nivel inicial y del desarrollo de las habilidades de los profesores para planificar situaciones de enseñanza con la definición y con la identificación, fueron utilizados los siguientes elementos: el dominio del concepto, el dominio de esos procedimientos lógicos y las categorías del planeamiento (objetivos, contenidos, estrategias de enseñanza, control y evaluación). En cada etapa surgieron obstáculos, pero también aspectos que han revelado la posibilidad para aprender una nueva forma de planear, con apropiación de nuevos fundamentos teóricos. La práctica docente se constituyó en un elemento que facilitó la comprensión y la apropiación de las habilidades de planear situaciones de enseñanza de conceptos mediante la definición y la identificación

Geometrizando no segundo ciclo :relato de uma intervenção pedagógica voltada à construção de conceitos geométricos no ensino fundamental

This work has proposed to relate the experience product of a pedagogical intervention, performed in a public institution of teaching situated in this capital. It had as objective to validade the applying of a teaching module of geometry, more specifically about the conceptions of perimeter and área in the second cycle of fundamental teaching. This dissertation has presented the problematic which involves the teaching of geometry in different contexts. It has adopted the broach of the radical constructivism while methodological theoretical referencial through which it has tried to explain the phenomena that involves the teaching and the apprenticeship. It appropriates Jean s Piaget contributions related to the development stages, while referencial that will dialogue in the search by sense and comprehension of the geometric apprenticeship process and it runs over Richard s Skemp (1980) theory in order to explicit the student s apprenticeship according to the levels of instrumental comprehesion and relacional comprehension . The research has presented datum related to initial diagnosis evaluantion, the pedagogical intervention and analysis of the activities and students perfomance displaying still the results of the final evaluation. According to the results got, we could check the students group growth front to the acquisition of the concepts of perimeter and área in comparison with the previous knowledges presented in the initial diagnosis evoluation of the students participants of the research. We have concluded evaluating the objectives of the research, connecting the strategies and reasoning employed by the students in order to resolve the questions and then to reach the objectives proposed by the teaching module. We have presented still the main obstacles to the apprenticeship of such concepts

Participação de mulheres na história da Escola Mista no Pará - 1870/1901

This study aims to problematize the history of mixed schools in Pará, from 1870 to 1901, highlighting women participation that helped to build them. The analytical focus of the research fell on the changes and the continuities of the mixed school in Pará. The object of analysis is the Paraense mixed schools, formed by women. The study also brings out arguments that the mixed school was set up in variable forms, concepts, times and spaces, in an overlapping with the inclusion of women in educational universe, either through education, professionalization or teaching in schools of girls and boys. The documentary sources privileged by the study are: the educational law, the newspapers, the government reports and the journals of education, which were examined in a confrontation between what was said and done. The evidential method helped the documentary reading revealed that, in small lines, the linkages built in the search for clues and signs of Paraense mixed schools was assembled with the participation of women, from the perception that historical knowledge is indirect, conjectural. Evidences indicated that the school for both sexes, legally established in the Province of Grão-Pará in 1870, gave the signals of the junction of girls and boys in school, at a time when the presence of women in education was suggested. Mutations related to the educational organization, with the introduction of mixed school in the following decade had a closer relationship with restrictive settings and more effective integration of women in that school. The inaccuracies of the Republican mixed school have revealed, through winding paths, that signal of contradictions between the modern discourse and conservative practices regarding this school, in communion with the expansion of the mixed school throughout the state, including in groups schools, observing the presence of effective women teachers in the regency of such schools and an expansion of students in relation to the equity between the sexes

Reflexões sobre a construção e evolução de conceitos geométricos nas séries intermediárias do ensino fundamental

This thesis represents a didactic research linked to the Post-graduation Programme in Education of the Universidade Federal do Rio Grande do Norte which aimed to approach the construction of the geometrical concepts of Volume of the Rectangular Parallelepiped, Area and Perimeter of the Rectangle adding a study of the Area of the Circle. The research was developed along with students from the 6th level of the Elementary School, in a public school in Natal/RN. The pedagogical intervention was made up of three moments: application of a diagnostic evaluation, instrument that enabled the creation of the teaching module by showing the level of the geometry knowledge of the students; introduction of a Teaching Module by Activities aiming to propose a reflexive didactic routing directed to the conceptual construction because we believed that such an approach would favor the consolidation of the learning process by becoming significant to the apprentice, and the accomplishment of a Final Evaluation through which we established a comparison of the results obtained before and after the teaching intervention. The data gathered were analyzed qualitatively by means of a study of understanding categories of mathematical concepts, in addition to using descriptive statistics under the quantitative aspect. Based on the theory of Richard Skemp, about categorization of mathematical knowledge, in the levels of Relational and Instrumental Understanding were achieved in contextual situations and varied proportions, thus enabling a contribution in the learning of the geometrical concepts studied along with the students who took part in the research. We believe that this work may contribute with reflections about the learning processes, a concern which remained during all the stages of the research, and also that the technical competence along with the knowledge about the constructivist theory will condition the implementation of a new dynamics to the teaching and learning processes. We hope that the present research work may add some contribution to the teaching practice in the context of the teaching of Mathematics for the intermediate levels of the Elementary School

Cinema e educação :interfaces, conceitos e práticas docentes

This project goes beyond the interfacial field of cinema, History and education. We take as our object the epistemological potential of the cinema at the educational scenario, specifically the use of films integrated to the practices of History teachers and educative processes in which we have taken part as a builder. Our objective is to map, initially, the knowledge around this use to search a synthesis and its empirical application. From the methodological point of view, we have made use of different perspectives: (a) interviews with the educator subjects; (b) observation of their practices and formative circumstances; (c) filmic analysis and the relation of the cinema s epistemology with the other areas ones (initially History and further Journalism). Our analysis allowed us to portrait the film such as an epistemological-troubling category, what makes the cinema rather a builder technology and not simply a complementary and illustrative technological resource. Therefore, we have realized that the restriction to the cinema s educational function is linked to the restrictions to the theoretical categories to an only interfacial aspect: historical film as a film which portraits the past (at the historical field) and film on journalism as a film which approaches a single object of Journalism (at the journalistic field). These discussions happen, consequently, at the arena of the nature of cinema s genres (fiction and documentary), which are understood in a naïve way, simpler than its epistemological possibilities, boosted at this research when we analyze the confluence between fiction and reality. The reflections on educative practices and in formation related to the cinema had occurred in three empirical realities: research with professors in performance, practices docent s and accompaniment of students of history. Have to do with our personal career as a teacher and researcher and, when analyzed other practices, have become, unavoidably, the subject and object of this project

Praxiologia, representação social de menopausa e práticas educativas de enfermeiras na estratégia saúde da família

This research, whose theme is related to climacteric, aims to know the social representation of menopause developed by the nurses working for Estratégia Saúde da Família (Family Health Strategy) in João Pessoa PB, as well as identifying its structure and verifying the way it interferes with the assistance and educational practices to the climacterial user. In the theoretical level, it is based on a model that articulates the social representations theory, the central nucleus complementary theory and the central concepts of Pierre Bourdieu s praxiology: habitus, cultural capital, social field and symbolic power. A hundred and forty-seven female nurses who work for Estratégia Saúde da Família (Family Health Strategy) in João Pessoa (PB) took part in this research, and the data collection period was from February 2008 to March 2009. As to the methods and techniques, we used the method to determine the central nucleus based on the free association of words, a questionnaire to identify certain regularities that constitute the nurses habitus, and the semi-structured interview to explore opinions and attitudes when facing assistance situations and educational practices and to collect other relevant information. The data analysis was developed, when referring to the free associations, with the help of the EVOC software, which is a group of articulated programs which carry out the statistical analysis of the evocations and the identification of the possible elements of both the central nucleus and the peripheral system of the social representation. As to the questionnaire, we used the descriptive statistical analysis and the analysis of correlation between the variables. The interviews were submitted to a categorical analysis of the content. The EVOC result indicated that the cognition hormone was the only element of the central nucleus of the social representation of menopause. Due to its symbolic value and structuring power, this central nucleus ensures the strict and, at the same time, flexible character of the representational content. The analysis of the social advancement, of some fundamental features of the group habitus, as well as the analysis of its insertion in the health field and of the attitudinal opinions and dispositions concerning the assistance given to the climacterial user, and the analysis of the pedagogical dimension of this assistance, all these analyses lead to the conclusion that the nurses who took part in this research share a social representation of the menopause resulting from the association of different technical and scientific knowledge. These derive from the biomedical pattern as well as from hegemonic values which disqualify old age and overvalue youth, from pedagogical conceptions arising from patterns that are presently regarded as authoritative and old-fashioned and from cultural references (responsible for the semantic variations concerning the central nucleus) which are specific to the subgroups the nurses belong to. This research enables the creation of opportunities for discussion between active nurses working for Estratégia Saúde da Família, and the nurses who are teachers at institutions of higher education, aiming at linking theory to practice, so that they can find ways of thinking about the climacteric and working, in a more comprehensive way, with users who are experiencing this stage of life

Avaliação do programa escola ativa como política pública para escolas do campo com turmas multisseriadas: a experiência em jardim do seridó/rn (1998-2009)

This work aims at developing an evaluation of the implementation of the Program Escola Ativa as a public policy for rural schools with combined grade classrooms in Jardim do Seridó RN (1998 2009) focusing on the following dimensions: school s physical environment, training, follow up, and didactic usage of the methodology. In order to develop this research we refer to the literature that analyzes the cycle of policies (FREY, 2000). In this approach, evaluation represents an important step in the process of analyzing the implementation of public policies, as a way of measuring up their performance, as well as a guide for realignments and redefinitions (PRESSMAN; WILDAVSKY, 1998). In order to accomplish this function, the evaluator of policies must be acquainted with scientific concepts and methods that consist of describing, interpreting and analyzing the policies in the governmental sphere (MENY; THOENIG, 1992; LIMA JÚNIOR, 1978). In this perspective, we intend to investigate whether in its proposition of minimizing the blanks in the Brazilian educational system, the implementation of the Program would be contributing to the improvement of the political-pedagogical practices in the rural schools with combined grade classrooms in Jardim do Seridó RN. In order to do this research, we have developed a theoretical-methodological matrix made of analysis dimensions, variables, indicators and instruments, such as literary revision, documental analysis, semi-structured interviews with four teachers and three supervisors that work and/or have worked in Escola Ativa in that town in the period comprised among 1998 2009, besides notes taken from field observation and photographs from four rural schools with combined grade classrooms. With this research we have identified that the Program, at a national level, has gone through different phases in its implementation process, for the town was not ready to fully take the responsibilities of the autonomous expansion, in 2002. From that period on, the execution of Escola Ativa has suffered several discontinuities, such as the lack of professional training and supervising. It is also noted that the methodology contributes to the dynamization of the didactic-pedagogical activities and promotes the cooperation and autonomy of the students in the organization and the applicability of the components of the curriculum, especially of Governo Estudantil and Cantinhos de Aprendizagem. Although the directions of the Program (BRASIL, 2005) point out that Escola Ativa has among its principles social transformation, we identified that, isolated, the initiative is not capable of promoting the changes that the rural schools need, namely investments in the physical, material, pedagogical and technological infra-structure, besides the estimation and a career plan for the teachers. In a general draft of the results of this research, we realized that some aspects presented about the peculiarities of Escola Ativa in Jardim do Seridó as a governmental Program, reinforce the need for the public policies to be evaluated, in order to confront critic and operationally the planning with the practice, revising action, whenever necessary

Pensando e agindo: estudo da relação entre o dsenvolvimento do pensamento e prática pedagógica

Este trabajo, intitulado pensando y actuando: estudio da le relación entre el desarrollo del pensamiento y la práctica pedagógica del profesor, tiene como objetivo investigar la relación entre el desarrollo del pensamiento teórico y la práctica pedagógica de una profesora de la educación pre primaria que actúa en una escuela pública de Natal / RN, con niños de edades variables de cuatro a cinco años. En términos específicos, pretendemos propiciar la continuidad de un proceso de formación que le permita elaborar el significado de los conceptos que componen los conocimientos curriculares, específicamente, el concepto de familia; tener el dominio de los procesos y procedimientos lógicos inherentes al desarrollo del pensamiento y la formación del concepto; mediar de forma consciente y planeada las etapas necesarias para que se efectiven los procesos de elaboración conceptual propicios al desarrollo del pensamiento. Para desencadenar el proceso investigativo, utilizamos los principios del materialismo histórico-dialéctico mientras que para el método de análisis, porque comprendemos que, a través de esta lógica, es que podremos buscar los elementos que darán sustentación a una mediación pedagógica que permita mayor eficacia en la comprensión de los fenómenos. Recurriremos a la investigación colaborativa, una vez que era nuestra intención desarrollar una acción investigativa compartida, teniendo en vista buscar medios para resolver los problemas de la práctica pedagógica. La investigación colaborativa posibilita al sujeto participante reflexionar, ser investigador, coadjutor-constructor de su práctica. Así, algunos procedimientos metodológicos fueron considerados adecuados para que pudiéramos alcanzar los resultados deseados, como Reuniones, Planeamientos, Ciclos de Estudios Reflexivos, Observación Colaborativa, y Sesiones Reflexivas. Utilizamos la metodología conceptual de Ferreira (2009) como soporte para el análisis del concepto de familia elaborado. Para hacer el análisis de ese proceso nos utilizamos de las teorizaciones de Vigotski (2009, 1998), Rubinstein (, Liublinskaia, Ferreira, Freire, entre otros. Podemos decir que, en la perspectiva de la colaboración, la reflexión sobre la práctica puede desencadenar una nueva visión del profesor sobre su práctica pedagógica y el desarrollo del pensamiento de su alumno. Los resultados obtenidos nos muestran que este fue un trabajo bien sucedido en el sentido de que percibimos una relación estrecha entre lo que la profesora realizó y los aprendizajes adquiridos por los alumnos. El sentido que la participante da a su hacer posibilitó la abertura de caminos para el desarrollo del pensamiento, a partir del trabajo con la metodología conceptual, revelando la conciencia del significado de su acción, y dialogando con las necesidades del alumno y trabajando las. Destacamos la importancia de la colaboración y del proceso reflexivo para la formación y la práctica del profesional profesor y los aprendizajes adquiridos con relación al reflexionar crítico y colaborativamente, en la argumentación y en la reformulación de nuestras ideas. Afirmamos que lo que realizamos es apenas el comienzo de nuevos caminos que surgirán por la necesidad que tenemos de busca, de descubiertas, y por las ganas de desarrollar acciones productivas, propicias de condiciones para la expansión de la formación profesional y de la práctica pedagógica del profesor. Las conclusiones a que llegamos están lejos de que se acaben, ya que es un tema complejo, que puede posibilitar el surgimiento de nuevos estudios, de nuevas investigaciones, de nuevos conocimientos

Um estudo sobre a aprendizagem de alguns conceitos algébricos e geométricos

The objective of the present work was develop a study about the writing and the algebraic manipulation of symbolical expressions for perimeter and area of some convex polygons, approaching the properties of the operations and equality, extending to the obtaining of the formulas of length and area of the circle, this one starting on the formula of the perimeter and area of the regular hexagon. To do so, a module with teaching activities was elaborated based on constructive teaching. The study consisted of a methodological intervention, done by the researcher, and had as subjects students of the 8th grade of the State School Desembargador Floriano Cavalcanti, located on the city of Natal, Rio Grande do Norte. The methodological intervention was done in three stages: applying of a initial diagnostic evaluation, developing of the teaching module, and applying of the final evaluation based on the Mathematics teaching using Constructivist references. The data collected in the evaluations was presented as descriptive statistics. The results of the final diagnostic evaluation were analyzed in the qualitative point of view, using the criteria established by Richard Skemp s second theory about the comprehension of mathematical concepts. The general results about the data from the evaluations and the applying of the teaching module showed a qualitative difference in the learning of the students who participated of the intervention

Conceitos e práticas educativas nos regimentos escolares no Rio Grande do Norte (1910 1930)

This research aims to analyze the concept of childhood in the dimension of educational practice, which is present in the regimental school and historically constructed power relations during the period 1910 to 1930, in Rio Grande do Norte. To contextualize this study, it is necessary to address the Bylaws of the School Groups (1915), the Internal Isolated Schools (1925) and Education Reform (1916). The expansion of education in the State, aiming at preparing the individual for the new capitalist social order was the concern of all governments of the first republic. During this period, the school is conceived as a privileged scenario of a set of practices aimed at disciplining the children, to explore, in some respects, the concept of childhood. Over time, this cocepção was constructed historically. In addition, the school receives children, which in the late nineteenth and early twentieth century, are inserted into an educational process in line with the state, embodied in laws, regulations and school discursive practices

Predição da maturação puberal de indivíduos do sexo masculino a partir de variáveis antropométricas

The methods of analysis of the selection system sports talent sometimes do not consider the biological age of the athletes, since that the assessment of maturational moment have several limitations The aim of this work is to develop a predictive equation of pubertal assessment in male subjects, based on anthropometric measurements. We evaluated 206 young boys, aged between eight and 18 years, and studing in public and private schools in Natal, Brazil. The sample selection was done randomly, being used the anthropometric measurements and pubertal maturation evaluation according to the Tanner stages. Statistical analysis followed the presentation of central tendency measures and their derivatives. The inferential analysis was performed according to the ANOVA test, multivariate discriminant analysis and weighted Kappa. The advancement of pubertal stages was accompanied by significant changes in anthropometric variables, demonstrating the relationship presented in both. For this purpose, discriminant analysis selected eight variables with the highest prediction of pubertal maturation, and created an equation with a significance level of 75%. and concordance level of 0.840, considered as excellent. This shows that the prediction of pubertal maturation from anthropometric variables presented as a valid method, being used as a practical tool in sports talents selection
