As tendências do mercado mundial de alimentos apontam para alto crescimento no consumo de produtos naturais, como as frutas e verduras. O mercado mundial de frutas frescas registrou, em 2005, cifra superior a US$ 31,5 bilhões e cresce US$ 1 bilhão ao ano, em média. Tal fato se reproduz no Brasil, onde se observa elevação do consumo de frutas. em termos monetários, o valor bruto da produção de frutas no Brasil atingiu, em 2006, cerca de R$ 16,3 bilhões, 16,5% do valor da produção agrícola brasileira. O presente trabalho buscou analisar características econômicas da participação brasileira no comércio mundial de frutas, entre 1997 e 2008. Ademais, foi analisada a evolução da balança comercial das principais frutas brasileiras, discriminação das exportações em frescas ou processadas, representatividade do comércio externo no valor da produção nacional e participação da exportação de frutas selecionadas na exportação total do agronegócio. Foram utilizados dados da Pesquisa de Orçamento Familiar (POF) do Instituto Brasileiro de Geografia e Estatística; o Sistema de Análise e Levantamento do Comércio Exterior - AliceWeb do Ministério do Desenvolvimento, Indústria e Comércio Exterior e o banco de dados do Ministério da Agricultura, Pecuária e Abastecimento. Após levantamento das frutas que seriam estudadas, constatou-se que o crescimento das exportações foi maior que o crescimento das importações brasileiras de 1997 a 2008. Isso contribuiu para que o seu saldo comercial aumentasse em 112% no período. As exportações de frutas frescas cresceram relativamente mais que as exportações de frutas processadas. Porém houve queda da participação das exportações de frutas nas exportações do agronegócio brasileiro, de 5,8%, em 1997, para 3,9%, em 2008.

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

This research work deals with the compilation of a dictionary on clothing terminology intended to be used as a pedagogic tool as part of the teaching and learning process in the Textile Engineering Course at the Federal University of Rio Grande do Norte. The main terms were selected and assessed by a team of textile teachers and students with the objective to be structured as a conceptual body of information on the following sub-areas of clothing terminology: materials (fabrics and trimmings) and products (garments). This research comprises three main steps: (a) characterization and understanding of the technical vocabulary in the clothing area as well as the identification of a pedagogic demand for a dictionary on clothing terminology, clearly expressed by the textile lecturers and students involved in the assessment of the need and validation of this project development; (b) a proposal for a specific methodology for the compilation of the dictionary which could help the communication process in the lecturing of clothing terminology and (c) based on the terminological principles and the technique of focal groups the dictionary was assessed. The technique of focal groups was used in the first step. In the second step the technique used was that of the terminological methodology adapted to the teaching approach in the Textile Course. In the third step the technique of focal groups was again utilized. It was observed that the main concern of lecturers and students is the lack of a standardized vocabulary, which renders difficult the communication process in both the teaching and learning activities as well as the professional ones in the textile industries. Various aspects, which can overlap, cause this lack of standardization. The main ones pointed out by the study team in the focal groups are: usage of regional words or expressions, usage of foreign words or expressions, analogies, and the low level of formal education, mainly among the industry workers. Another aspect to be considered is the lack of textile literature written in the Portuguese language of Brazil. This evidence shows the importance of a clothing terminology dictionary which will benefit both the education and professional activties in this field of knowledge. This dictionary will also give a substantial contribution to terminological standardization in our research field. With view to fulfill this demand, a dictionary of clothing terminology was compiled with 760 main entries, according to the modern practice in terminology with the necessary modifications concerning our needs. The result of the dictionary assessment was very assertive regarding its structure, contents and possible use in various contexts. The team work emphasized their contribution to the standardization process of the terms that proved to be one of the most important and difficult aspects of this researh work. The significance of this structured terminological dictionary was confirmed by the focal group participants relating to its use for teaching and learning activities, as a reference book, as a source of technical information and also as a tool for pedagogic studies and planning, as well as a significant collaboration to the pedagogic practices in the textile engineering course at University or any other educational institution. Besides, this dictionary can also be used to supply information within the textile field. We are aware that the present work will not exhaust the objectives of this research due to its limitations in opposition to the vast complexity demanded by the compilation of a complete work including all the areas and sub-areas of textile engineering. However, it is an important source for dissemination of concepts on the field of clothing terminology and a tool to effective standardization of the terms used in this subject field

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

Los estudios cerca de las dificultades en el aprendizaje del contenido de la biología han sido foco de la investigación diversa que si ten corido a partir de la década de setenta del siglo pasado, en consecuencia al movimiento de las concepciones alternativas (MCA). El estudio que se presenta, se atan con el Departamento de Educação da UFRN - Base de Pesquisa Formação e Profissionalização Docente, como parte do projeto de pesquisa - A passagem do Ensino Médio a UFRN: estudos sobre o acesso, a permanência e a qualidade do Ensino Médio. Los objetivos de esto investigación, habían consistido en el identificar del contenido explorado en las cuestiones de las Pruebas de la opción múltiple del Vestibular de UFRN para el cual los candidatos habían demostrado dificultad en el aprendizaje; para analizar si el contextualização de la pregunta y la presencia de elementos no-literales que habían influenciado en el aumento de la dificultad de la pregunta e identificar los errores más frecuentemente por los candidatos en estas pruebas. La tesis si configura en dos dimensiones: 1 - El contenido explorado en las Pruebas del Vestibular de la UFRN si distribuya uniformemente a través de los años; sendo priorizados procedimentos que exigem demanda cognitiva diversificadas na solução de problemas; 2- Nessas provas, os resultados dos candidatos, en relación con el Índice de Aproveitamento, indican la existencia de áreas en las quales hay déficit del aprendizaje; qué envolucran las dificultades en aprender el contenido. Los datos de la investigación habían sido recogidos al partir de las pruebas de la biología y de la inicial abstracta selectiva de los informes proveído para el COMPERVE/UFRN, del último los ocho años (2001-2008). En la dirección alcanzar a los objetivos considerados para este estudio, contenta había sido construido a las categorías del análisis - (temas, subtemas y procedimientos); índice de aproveitamento; contextualização de la pregunta; estructura de la pregunta y el error. Los resultados, qué si configurán de los análisis de las ocho pruebas del vestibular de la UFRN y los sesenta y cientos envolvement mil, seiscientos y sesenta y cinco candidatos que le habían contestado; demuestran eso: los temas y los subtemas de la biología para los cuales las dificultades en aprender si está tenido divulgado sea - genética (hibridismo; fenótipo y genotipo; Leyes de Mendel), biotecnología (transgênicos; célula-tronco) y citología (química de la vida; división celular; membranas) y los procedimientos - identificar, analizar la situación y aplicar concepto, para correlacionar y para interpretar el gráfico; los quais não exigem uma alta demanda cognitiva na solução dos problemas. La presencía de situações contextualizadas e de gráficos en las questiones de las pruebas influenciou en el aumento dos niveles dificuldade da of questão para a maioria dos candidatos, reiterando as of dificuldades of observadas na of aprendizagem dos procedimentos. Los errores principales cometidos para los candidatos habían consistido en no reconocimiento del estándar de la herencia del gênica - mendelian y después de-Mendel; no del reconocimiento de los acontecimientos de la división celular y de las técnicas en biotecnología. Éstos habían reflejado las dificultades en aprender del contenido para algún contenido y en otros sugieren que tuviera la expresión de los conceptos alternativos que los estudiantes construyen en los conceptos. Los resultados señalan la necesidad de una revisión de las preguntas inherentes didácticas-metodológicas a la educación del contenido para las cuales las dificultades en aprender si hay tenido presentado

Cette étude appartient à l un des principaux défis de l éducation dans l actualité qui est la production de connaissances concernant la mort comme objet d investigation théorique et empirique dans le domaine éducationnel. Des recherches récentes signalent le besoin d une éducation contemplant des études sur la mort et montrent l école tel qu un lieu de débats et reflexions à propos de ce thème. Cette reflexion est relevante et fondamentale, étant donné que la mort fait partie du cycle de la vie et se trouve présente dans les contenus scolaires des différents domaines de la connaissance. Ce travail a, donc, l objectif d analyser les signification attribués à ce concept mort et la relation qui s établit entre eux et la pratique des professeurs de l enseignement fondamental. Il adopte en tant que référentiel les principes de la recherche qualitative du type étnographique (André, Chizzotti et Meksenas), dans une approche socio-historique et en ce qui concerne la formation et le développement des concepts (Vygotsky, Kopnin, Guetamanova et Ferreira). La participation des professeurs a été faite par l observation participante, registres en cahier de bord et application d un instrument de construction de données pour l appréhension des significations attribués aux concepts qui sont à la base de la pratique de cinq enseignantes des premières séries de l Enseignement Fondamental d une école publique du réseau d enseignement de l État du Rio Grande do Norte située dans la Zone Sud de Natal. De ce fait, les analyses et les interprétations des observations de la pratique dans la salle de classe et des réponses aux quinze questions liées au thème ont permis de construire les significations des concepts qui appuient les pratiques enseignantes de ces professeurs, tout en mettant en relief la fragmentation et la désarticulation entre les expressions décrites dans les questionnaires et les pratiques développées en salle de clase. Ces reflexions mettent en évidence la nécessité de re-penser l articulation entre l énnoncé et la pratique des professeurs à propos de cette thématique au cours d une formation initiale et continue

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

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

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

We make many journeys during our lifetime. In each of them we accumulate experiences that result in an amount of knowledge that constitutes our history. The dissertation presents one of these journeys: that one I took along with students of Pedagogia da Terra project from Universidade do Estado do Rio Grande do Norte UERN to think about the knowledge within their memories in their way from countryside to city seeking for education. I used as main references to this task the ideas of Edgar Morin about Method as Strategy, implication of the subject in knowledge, pertinent knowledge, and knowledge reconnection. And from Paulo Freire I used the concepts of cultural identity assumption and dialog. I built as resource of method the metaphor of the suitcase, called by me the trunk of memory treasures . The use of this cognitive operator makes possible for those students bring their memories to the surface and share them collectively, by the process I name as auto-social- biographical narratives. The explicitness of the memories they choose to reveal by means of these narratives permitted me to understand the metamorphosis of these knowledge since their childhood to nowadays. In order to present an archeology of knowledge within these life histories I chose a narrative writing style concerned with simplicity and lightness, where I use the description of facts and discussions occurred during this journey. My main arguments in systematizing this experience are: scientific production can and should be grounded on knowledge diversity and on a more sensible approach to phenomena; education and pedagogy need to take as starting point and fuel for their practices the singularities of the subjects, their life history, educational background and knowledge resulting from both. Teacher s formation programs which students have mixed, rural and urban, background should value cognitive experiences built in the interaction with that knowledge closer of a sensible logic, deeper grounded in land and nature. Doing so, education can contribute to join diverse knowledge against monocutural forms of thinking and educational practices

Background: Bull fertility is extremely important for beef cattle production systems and has a multiplier impact on the economical and zootechnical indexes of the herd. Bulls raised in tropical conditions may present varied seminal characteristics due to, among other causes, different management practices and quality of pastures. Another factor that influences the semen characteristics is the age of the sire. The reproductive potential of bull evaluated through the andrological exam aims to ensure the semen quality and to improve the herd reproductive efficiency. The aim of this study was to evaluate the main semen parameters of Brangus-Ibage bulls extensively reared in eastern Mato Grosso do Sul state and to verify the effect of age on the andrological characteristics analyzed. It was also evaluated the correlation between age, scrotal circumference, and physical and morphological sperm characteristics produced by the Brangus bulls.Materials, Methods & Results: The study took place in the month of July 2010, during the routine andrological examination of 168 synthetic Brangus-Ibage bulls (5/8 Angus x 3/8 Nelore), belonging to the same property. For data analysis the animals were divided by age groups: animals younger than 4 years (Age I), animals between 4 and 8 years of age (Age II), and animals between 8 and 15 years of age (Age III). In another analysis, the animals were grouped according to the sperm motility pattern obtained from the semen collection: sperm motility lower than 40% (Motility I), sperm motility between 40 and 70% (Motility II) and sperm motility between 70 and 90% (Motility III). The results of the present study demonstrated an effect of age (P < 0.05) on the following androgical characteristics: scrotal circumference, ejaculate volume, sperm vigor, major defects, minor defects and total defects. It was also observed that the animals with higher sperm motility presented higher (P < 0.05) scrotal circumference, and lower (P < 0.05) percentages of major and total defects. Among the andrological characteristics evaluated in the present work, it was observed positive correlations between age and scrotal circumference (R =0.299; P =0.000), age and volume of ejaculate (R =0.161; P =0.037), age and major defects (R =0.188; P =0.015), sperm motility and scrotal circumference (R =0.245; P =0.001), sperm motility and sperm vigor (R =0.483; P =0.000), and between major defects and total defects (R =0.946; P =0.000). Also, negative correlations were observed between sperm motility and total defects (R =-0.372; P =0.000), sperm vigor and major defects (R =-0.498; P =0.000), and sperm vigor and total defects (R =-0.432; P =0.000).Discussion: Based on the results of this study it was concluded that the Brangus-Ibage bulls utilized for natural breeding in eastern Mato Grosso do Sul, Brazil, presented satisfactory semen quality taking into account the quality of the pastures where the animals were located. In addition, the scrotal circumference, the ejaculate volume, the sperm vigor, and the percentage of morphological characteristics were influenced by the age of the bulls. Therefore, considering the production system and the environmental conditions, the animals with age between 4 and 8 years were superior regarding the sperm parameters evaluated.

Access is a problem of higher education in Brazil that has existed since the formalization of this has occurred since the installation of the Portuguese court in Brazil in 1808. Only 10% of young people between 18 and 24 years of age attending this level of education in 2000, arriving in 2010 just 15%, far from that determined the National Education Plan in 2001, triple that percentage by the year 2010. In addition, a majority of seats of public HEIs is populated by students from the private network, especially in high-demand courses. In this context, this study aims to identify the costs related to the trajectories of students who were successful in the vestibular UFRN editions from 2006 to 2010. Presents an overview of higher education in Brazil, a brief history of vestibular, as well as new forms of access, and some of the policies to expand such access, highlighting the argument Inclusion UFRN. Focusing on the theme of the paper presents the concepts of opportunity costs and social. After collecting data through a questionnaire and consultation of databases COMPERVE was developed to search for a descriptive and analytical, with the participation of 3,995 students, of whom 1642 (41.1%) had completed secondary education in schools public, and 2,078 (52%) in private schools. The profile indicates that 90% are single, about 50% are 21 years of age, are white and female. In the course of preparation for college entrance exams, 80% chose the course during or after completion of the last year of high school, and almost 70% said they had started preparing at that time. Findings related to the costs involved with this preparation indicate that, in most cases there were school fees and disbursements and workshops, and the purchase of books and other materials, with parents primarily responsible for this cost, the amount disbursed each month was up $ 300 for 64% of respondents and only 7% of them exceeded $ 1,000, the major non-financial costs were characterized by the following resignations: job opportunities (24%) or temporary work (20%) courses of languages (26%), leisure activities (48%), leisure travel (43%), and parties and / or shows (54%). Of social investments by the government, stand out in the tax waiver scholarships for study in private institutions, grant exemption from the registration fee of vestibular, the preparatory courses UFRN, and seminars by COMPERVE / UFRN with networks of high school. From the junction of the opportunity costs (private costs) and social costs (public costs), a new concept: the social opportunity cost, which measures the combined efforts of families and government to finance the opportunity to access higher education of an individual. This concept can and should be incorporated as a strategic vector for the sake of democratic university, which reflects the social model that is sought

Teaching formation has been the target of many changes, having been forged according to numerous formats and models through different times and spaces, composing thus, different codes and curricular proposals for different levels of qualification. We've tried in this work to pinpoint the main discussions which take place in the area of the teaching formation, based in the views of modern writers. We ve also tried, through the Social Representations Theory, to reveal and learn how the agents directly involved in this process realize and react, that is, the teachers who cope with the beginning stages of the Fundamental Teaching in the public school system in Natal/RN, taking into account that, in many cases, such formation demands the rethinking of the very formation policies. We've also adopted the concepts of field and educational field introduced by the praxiology of Pierre Bourdieu. It s been considered a fundamental theoretical reference which enables the understanding of social phenomena, both in macro and micro viewpoints. Thus, we do not neglect the whole, and particularly, the nuances of each context or specific situation. In the methodological track we ve used for data gathering the Free Word Association Test, and the Semi-Structured Interview, and also secondary sources for the characterization of the research spectre. Data treatment and analysis were performed with the help of the following software: SPSS Statistical Package for Social Sciences and EVOC; and the method of Content Category Analysis. The combination of the concepts and techniques mentioned above was necessary to cope with the qualitative and quantitative aspects, in our attempt to offer a wider range of contributions and outcome validations, which have shown, among other less explicit elements, the existence of a social representation of the teaching formation such as: knowledge theoretical and practical; a necessity imposed by the symbolical conflicts of the social field; capacitation and compromisse. We acknowledge the relevance of the thoughts discussed here, though aware that this is just one of the possible approaches to the theme

The present study analyzes the ethnomatematics practices presents in the creation of the geometric ornaments of the icoaraciense ceramic, originated and still practiced in the neighborhood of Paracuri, District of Icoaraci, belonging to Belém, capital of the State of Pará/Brasil. The object of our study was centered at the workshops supplied by the artisans master of the School of Arts and Occupations, Master Raimundo Cardoso. Referred school provides to its students, formation at fundamental level as well professional formation, through vocational workshops that help to maintain alive the practice of the icoaraciense ceramic. Our interest of researching that cultural and vocational practice appeared when we got in touch with that School, during the development of activities of a discipline of the degree course of mathematics. In order to reach our objective, we accomplished, initially, a research about the icoaraciense ceramic historic, since the first works with the clay until to the main characteristics of that ceramic. Soon afterwards, we discussed on ethnomatematics, culture, knowledge, cognition and mathematical education. At the end, we analyzed the creation of the geometric ornaments of the icoaraciense ceramic, considering the proportion concepts, symmetry and some geometry notions, that are used by the artisans when they are ornamenting the pieces of that ceramic. We verified that, in spite of the artisans, usually, do not demonstrate to possess a bit of domain on the mathematical concepts that they are working with, for instance, the ones of translaction symmetry, rotation and reflection, they demonstrate full safety in the use of those concepts, as well as the capacity to recognize them, even if in a singular specific and very peculiar way, what opens the possibility of a partnership among mathematics teachers and master-artisans of the archeological ceramic and icoaraciense workshops

In recent years, in Brazil, researches in the area of education have been focused on the study of the necessities of formation, by the practice of necessity analysis, to subside the continued teacher formation programs. This research on the necessity of the formation of literacy teachers in the initial years of primary education originated in our discussions in academia, regarding the issues of retention and evasion related to basic literacy teaching in Brazilian public schools. We defined as a goal: to know the necessities of the formation of literacy teachers from Odila Leite Municipal Elementary School, Natal/RN, which focuses on the literacy teaching on that level of education and in Adult and Youth Education. The object is the necessities in these teachers formation. The thesis is that the literacy teacher reveals/constructs formation necessities when speaking of her practice, when exerting said practice or even when producing teaching materials which subside that practice; in other words, when making the theoretical/practical relation related to literacy teaching. The approach is qualitative, according to which the natural environment is the source for data collection; the focus of interest is the process of knowledge construction, and fundamental importance is given to the meanings constructed by the subjects. We comprehended that necessity is a socially constructed subjective phenomenon, and that necessity analysis allows the revelation of formation objectives. We used the case study as a methodological strategy which permits: studying a well-defined entity, [ ] as well as an academic institution; the global comprehension of the phenomenon of interest; discovering what is most essential and characteristic in the object. We counted with 17 teachers, 3 of which had their teaching practices observed. We observed the school routine, analyzed the main class documents and plans and interviewed the 17 teachers. We triangulated the data obtained by the routine observation, the observation of the three teachers practices and by the document analysis, next, we triangulated this data with the data from the analyzing the interviews with the 17 teachers. Such procedures reveal formation necessities in those teachers , such as: studying child cognitive development; reviewing the concepts of literacy teaching; reviewing fundaments of written language psychogenesis; reflecting on reading practices and literature; reflecting on the practice of daily planning; reflecting on the school s material conditions and the family/school relation. We concluded that researches of this nature contribute to the orientation of teacher formation programs
