This thesis aims to investigate the Agronomy course in the perspective of the graduation course for the settlers of the Universidade Federal do Pará- Marabá. This course requires a partnership with the social movements of the North region of the country, with the purpose to understand knowledge production and how learning process occurs from the point of interaction and reliable relationships which are established in the organization during the course. The base of theses studies is to reflect of how the dialogue and learning processes occurred during the Agronomy course and resulted in changing in the teachers behavior and in the other integrated members of the group and mainly in the graduating settlers students. These changings happens as a consenquence of the dialogue production between the most varied areas, different people and institutions which take collective decisions. I observe educational actions, researches, extention concepts of extension and also development researches presented in the educative actions discussed by Freire (1985), Simões (2001, 2003) e de Amartya Sen (2000). The theory in which I am basing these studies are based in Boaventura de Souza Santos Simões (2001, 2003) and Amartya Sen (2000). Methodologically I analyse knowledge production by sudying the thesis and scientific works related to rural education, social movements, university and higher education in the last 20 years. I analyze the scientific works of all settler students, and besides, I do open interviews with the students, as well as, with the teachers and the leaders of social movements (MST, FETAGRI, CPT, EFA/FATA). I organize and analyze all the speeches from the ecological knowledge as defined by Boaventura de Souza Santos (2006). Finally, I visit five towns of municipal districts of the southeast of Pará, which represents the final methodological part of the research, in order to verify in loco the practices of the experiments purposed as final activity of the Agronomy course. I organize the work in five areas composed by the occupational process and the initiatives which emerged from them; development model and the social and environmental consequences; I also organize the university role and the relationship established between people and institutions which gave origin to the Agronomy course of UFPA and the programs developed in the region; conjuncture of creation of the groups of settled students, curriculum, principles and focus on the course and the experienced actions; developed practices in the course and the relations of reliability experienced internally and externally to the Academy, the learning and dialogue promoted by the course. I believe that the dialogue has caused changes in the organization of the knowledge and in the educative practices of the teachers, as well as, in the socio-productive practices of the regressed settled students

Kindergarten teachers training gains the spotlight with the passing of Law number 9.394/96 (Guidelines and Basis Law) that defines this segment as the initial step of basic education, with pedagogical function. In this spectrum, the discussion about teacher training unravels to ensure social quality to education as well as the teacher s specificities towards child singularities. Adding to that, the growing propagation of Pedagogy in an undergraduate level, given that such course has been continually transformed by the National Curriculum Guidelines for Pedagogy (2006), highlighting the addition of curriculum components that are specific to upbringing. The complex debate circa kindergarten teachers training has advancements and hardships that need to be unveiled in order to improve both formation and social quality of education in the 0- 5 years old range. This investigation inserts itself in said context and aims to analyze which knowledge, specific to kindergarten teaching are constructed, according to undergraduate trainees, in Pedagogy s supervised internship. The study was conducted alongside the discipline: Supervised Internship in Child Education ministered by the Advanced Campus of Rio Grande do Norte s State University s in the municipality of Patu-RN (CAP-UERN-Patu) and was conducted through 2012 by accompanying four undergraduate interns. We first assumed that the development of teaching knowledge is a complex process of appropriation of cultural-social practices and is symbolically mediated by interactions that occur in the formation context, and the supervised internship can be understood as a space for the articulation and enlargement of theoretical and practical knowledge, directly related to the specificities of child education. The theoretical-methodological foundation was based upon the historiccultural approach of L. S. Vygotsky and M. Bakhtin s dialogism on human sciences research, as well as his postulates on learning and developmental processes, conceived as both essentially social and discursive. The investigation approached the principles of the qualitative perspective and to the construction and analysis of data, involved documental analysis and, specially, semi-structured interviews, both individual and collective, whose fundamental premise was the production-comprehension of meanings in a dialogical perspective. The participants texts/speeches produced a synthesis that points to the occurrence, within the supervised internship at CAP/UERN, of internalization/appropriation processes and, as such, of formulation of meanings that are pertinent to child education: child, childhood, kindergarten and teacher signification and this stage s specific teaching knowledge. It stood out that the internship, alongside other curriculum components, is, in fact, one of the primeval formation environment for the teachers, in which the interns interact with their colleagues, supervisor professor, collaborator professor, and of course, the children to construct their erudition. Such interactions allow the undergraduate interns to develop attitudes and procedures to reflect on what they know, what they ve done and what they can achieve. We have concluded that the undergraduate internship can constitute itself as an articulatorconsolidator environment in the future teacher s formation process and, since well oriented, can provide the effective initiation, not only to the practice, but to the praxis as a movement of non dissociability between theory and practice

Este trabalho objetivou uma reflexão sobre a ação mediadora no processo de ensino-aprendizagem da leitura, por mim vivenciada no Núcleo de Educação Infantil (NEI/UFRN) junto a crianças de 6/7 anos, tendo como proposta explicitar os elementos orientadores necessários a esse processo, que se traduzam como referência a outras práticas educativas. Sua realização pressupôs as seguintes questões: que conteúdos estão envolvidos no ensinoaprendizado da leitura? Como os alunos aprendem a ler? Que tarefas são instrumentais no ensino e aprendizado da leitura? Nele foi adotada a concepção de leitura enquanto atribuição de significados a um texto escrito através do processo interativo entre leitor e texto, guiado pelos objetivos/finalidades deste leitor. Adotou os princípios metodológicos da abordagem qualitativa, entre cujas características salienta-se a primazia do interesse pelo processo do que simplesmente pelos resultados ou produto. Seus resultados evidenciaram que a leitura, enquanto prática cultural, pode ser aprendida na escola infantil, espaço de apropriação de saberes mediados pela cultura. Constatou-se que, a exemplo das demais aprendizagens, o aprendizado da leitura implica numa atividade mediada em que o professor, administrando e organizando o meio social educativo, cria espaços de diálogo para as muitas vozes presentes nesse meio. Gera, desse modo, um contexto polifônico, dialógico e de alteridade pela ação de planejar/avaliar/replanejar a sua atuação e a de seus alunos. A relevância deste estudo concerne à intenção de socializar uma vivência, cuja tônica é a reflexão sobre a leitura enquanto prática cultural e as estratégias de ensinar e aprender a ser leitor.
concepções de administração e administrador em tempos de capitalismo flexível: uma abordagem crítica
Resumo:
A tese trata de dois construtos sócio-históricos Administração e Administrador em face do capitalismo em sua fase flexível. Considerando as mudanças do capitalismo, o texto estabelece como objeto de estudo as concepções de Administração e Administrador, para o campo administrativo, na contemporaneidade. A tese é suportada por uma pesquisa de campo cujo objetivo foi compreender criticamente as concepções do campo administrativo sobre a Administração e o Administrador, em tempos de capitalismo flexível. Epistemologicamente, a pesquisa foi conduzida a partir da perspectiva crítica frankfurtiana, fundamentada em três pares categóricos dialéticos: (i) história versus naturalização; (ii) práxis social versus sistema; e (iii) alienação versus emancipação; privilegiando o pensamento crítico vinculado à primeira geração da Escola de Frankfurt. A literatura prevalente da área de Administração foi revisada mediada pelas duas questões ontológicas que suportam a tese: O que é Administração? e O que é Administrador? para autores como Taylor, Fayol, Drucker, Ohno, Deming, Champy e Mintzberg. Metodologicamente, foi realizada uma pesquisa integralmente qualitativa, com uso de três tipos de entrevistas: (i) entrevista narrativa com história de vida; (ii) entrevista com uso de elementos-estímulo; e (iii) entrevista narrativa ficcional. Para compreensão das narrativas, foi utilizada a técnica de análise hermenêutico-dialética. Os resultados indicam o predomínio da concepção pragmática-instrumental, no tocante à Administração, pela qual ela continua a ser pensada e discursada como uma ação tecnológica e teleológica, que utiliza saberes múltiplos e aprendizagens cambiantes como meios para alcance das finalidades do contexto organizacional mutante. Com relação ao Administrador, há a emergência da concepção estética para apresentá-lo, quando vinculado às organizações. Por esta concepção, há a migração do histórico estereótipo do Administrador controlador e vigilante para a representação do Administrador como um profissional performático. O segundo resultado, que se apresenta como o mais relevante em relação ao Administrador, é o da fuga da profissão. A partir dos pares categóricos dialéticos, esta tese propõe algumas sínteses provisórias críticas: (i) história-naturalização: os sujeitos tomam como naturais a organização empresarial e suas demandas, naturalizando as recentes mudanças que, entre outras coisas, reduzem os postos gerenciais; (ii) práxis social-sistema: pela concepção pragmática-instrumental, as experiências dos Administradores são concebidas a partir do confinamento funcionalista em uma organização-sistema; (iii) emancipação-alienação: tanto a forma naturalizada com que especificam as organizações e sua Administração quanto a práxis interrompida velada em uma experiência reificada mostram-se como fenômenos intrinsecamente e subjetivamente alienantes e contraemancipatórios. Por outro lado, através do movimento de fuga da profissão, os entrevistados parecem (re)significar o silêncio fundador da alienação associada à condição de Administrador: a de pensar como capital, e não se pensar como trabalho. Finalmente, o texto propõe que as possibilidades de emancipação deste profissional residem na tomada de consciência de sua condição como integrante da classe trabalhadora, mesmo em tempos de riscos e incertezas. Assumindo-se como trabalhador, o Administrador poderá lutar pelo seu trabalho, repensando-o em novos termos, em que as dimensões pragmáticas-instrumentais que envolvem sua profissão possam ser dosadas e sempre mediadas por conteúdos substantivos e emancipatórios

The research and development of wind turbine blades are essential to keep pace with worldwide growth in the renewable energy sector. Although currently blades are typically produced using glass fiber reinforced composite materials, the tendency for larger size blades, particularly for offshore applications, has increased the interest on carbon fiber reinforced composites because of the potential for increased stiffness and weight reduction. In this study a model of blade designed for large generators (5 MW) was studied on a small scale. A numerical simulation was performed to determine the aerodynamic loading using a Computational Fluid Dynamics (CFD) software. Two blades were then designed and manufactured using epoxy matrix composites: one reinforced with glass fibers and the other with carbon fibers. For the structural calculations, maximum stress failure criterion was adopted. The blades were manufactured by Vacuum Assisted Resin Transfer Molding (VARTM), typical for this type of component. A weight comparison of the two blades was performed and the weight of the carbon fiber blade was approximately 45% of the weight of the fiberglass reinforced blade. Static bending tests were carried out on the blades for various percentages of the design load and deflections measurements were compared with the values obtained from finite element simulations. A good agreement was observed between the measured and calculated deflections. In summary, the results of this study confirm that the low density combined with high mechanical properties of carbon fibers are particularly attractive for the production of large size wind turbine blades

The oil companies in the area in general are looking for new technologies that can increase the recovery factor of oil contained in reservoirs. These investments are mainly aimed at reducing the costs of projects which are high. Steam injection is one of these special methods of recovery in which steam is injected into the reservoir in order to reduce the viscosity of the oil and make it more mobile. The process assisted gravity drainage steam (SAGD) using steam injection in its mechanism, as well as two parallel horizontal wells. In this process steam is injected through the horizontal injection well, then a vapor chamber is formed by heating the oil in the reservoir and, by the action of gravitational forces, this oil is drained down to where the production well. This study aims to analyze the influence of pressure drop and heat along the injection well in the SAGD process. Numerical simulations were performed using the thermal simulator STARS of CMG (Computer Modeling Group). The parameters studied were the thermal conductivity of the formation, the flow of steam injection, the inner diameter of the column, the steam quality and temperature. A factorial design was used to verify the influence of the parameters studied in the recovery factor. We also analyzed different injection flow rates for the model with pressure drop and no pressure drop, as well as different maximum flow rates of oil production. Finally, we performed an economic analysis of the two models in order to check the profitability of the projects studied. The results showed that the pressure drop in injection well have a significant influence on the SAGD process.

Nowadays, most of the hydrocarbon reserves in the world are in the form of heavy oil, ultra - heavy or bitumen. For the extraction and production of this resource is required to implement new technologies. One of the promising processes for the recovery of this oil is the Expanding Solvent Steam Assisted Gravity Drainage (ES-SAGD) which uses two parallel horizontal wells, where the injection well is situated vertically above the production well. The completion of the process occurs upon injection of a hydrocarbon additive at low concentration in conjunction with steam. The steam adds heat to reduce the viscosity of the oil and solvent aids in reducing the interfacial tension between oil/ solvent. The main force acting in this process is the gravitational and the heat transfer takes place by conduction, convection and latent heat of steam. In this study was used the discretized wellbore model, where the well is discretized in the same way that the reservoir and each section of the well treated as a block of grid, with interblock connection with the reservoir. This study aims to analyze the influence of the pressure drop and heat along the injection well in the ES-SAGD process. The model used for the study is a homogeneous reservoir, semi synthetic with characteristics of the Brazilian Northeast and numerical simulations were performed using the STARS thermal simulator from CMG (Computer Modelling Group). The operational parameters analyzed were: percentage of solvent injected, the flow of steam injection, vertical distance between the wells and steam quality. All of them were significant in oil recovery factor positively influencing this. The results showed that, for all cases analyzed, the model considers the pressure drop has cumulative production of oil below its respective model that disregards such loss. This difference is more pronounced the lower the value of the flow of steam injection

The present study provides a methodology that gives a predictive character the computer simulations based on detailed models of the geometry of a porous medium. We using the software FLUENT to investigate the flow of a viscous Newtonian fluid through a random fractal medium which simplifies a two-dimensional disordered porous medium representing a petroleum reservoir. This fractal model is formed by obstacles of various sizes, whose size distribution function follows a power law where exponent is defined as the fractal dimension of fractionation Dff of the model characterizing the process of fragmentation these obstacles. They are randomly disposed in a rectangular channel. The modeling process incorporates modern concepts, scaling laws, to analyze the influence of heterogeneity found in the fields of the porosity and of the permeability in such a way as to characterize the medium in terms of their fractal properties. This procedure allows numerically analyze the measurements of permeability k and the drag coefficient Cd proposed relationships, like power law, for these properties on various modeling schemes. The purpose of this research is to study the variability provided by these heterogeneities where the velocity field and other details of viscous fluid dynamics are obtained by solving numerically the continuity and Navier-Stokes equations at pore level and observe how the fractal dimension of fractionation of the model can affect their hydrodynamic properties. This study were considered two classes of models, models with constant porosity, MPC, and models with varying porosity, MPV. The results have allowed us to find numerical relationship between the permeability, drag coefficient and the fractal dimension of fractionation of the medium. Based on these numerical results we have proposed scaling relations and algebraic expressions involving the relevant parameters of the phenomenon. In this study analytical equations were determined for Dff depending on the geometrical parameters of the models. We also found a relation between the permeability and the drag coefficient which is inversely proportional to one another. As for the difference in behavior it is most striking in the classes of models MPV. That is, the fact that the porosity vary in these models is an additional factor that plays a significant role in flow analysis. Finally, the results proved satisfactory and consistent, which demonstrates the effectiveness of the referred methodology for all applications analyzed in this study.

Analyze, in patients with primary hyperhidrosis (PH) who was undergone to videothoracoscopic sympathicotomy, the degree of vascular denervation after surgical transection of the thoracic sympathetic chain by measuring ultrasonografic parameters in carotid and vertebral arteries. Methods: Twenty-four patients with PH underwent forty-eight endoscopic thoracic sympathicotomy and were evaluated by duplex eco-doppler measuring systolic peak velocity (SPV), diastolic peak velocity (DPV), pulsatility index (PI) and resistivity index (RI) in bilateral common, internal and external carotids, besides bilateral vertebral arteries. The exams were performed before operations and a month later. Wilcoxon test was used to analyse the differences between the variables before and after the sympatholisis. Results: T3 sympathicotomy segment was the most frequent transection done (95,83%), as only ablation (25%) or in association with T4 (62,50%) or with T2 (8,33%). It was observed increase in RI and PI of the common carotid artery ( p<0,05). The DPV of internal carotid artery decreased in both sides (p<0,05). The SPV and the DPV of the right and left vertebral arteries also increased (p<0,05). Asymmetric findings were observed so that, arteries of the right side were the most frequently affected. Conclusions: Hemodynamic changes in vertebral and carotid arteries were observed after sympathicotomy for PH. SPV was the most often altered parameter, mostly in the right side arteries, meaning significant asymmetric changes in carotid and vertebral vessels. Therefore, the research findings deserve further investigations to observe if they have clinical inferences

Leukemia is a heterogeneous group of hematologic malignancies that result from partial or total transformation of the blast cells. The Acute Lymphoblastic Leukemia (ALL) is the most common malignancy in childhood, especially in male, Caucasian children younger than 14 years. Several criteria are adopted to classify ALL, including the cell morphology, cytochemistry, immunophenotyping and cytogenetic analysis. Cytogenetic studies allow a more detailed analysis to detect chromosomal abnormalities of leukemic cells. These modifications will determine the diagnosis, classification, stage characterization, remission assessment and prognosis. In this study were evaluated 30 patients, aged from four months to seventeen years, of both sexes and various ethnicities. The age distribution showed that 67% of patients had between one and ten years (with mean age of XX years old), the most prevalent ethnic was Caucasian (50%) and 57% were males. According to immunophenotype, 93% of patients had B-cells progenitor ALL and 7% early lineage T. Considering the total studied population, the most frequent medical findings were lymphadenopathy (37%), hepatomegaly (77%) and splenomegaly (70%), where one patient could present more than one of these medical findings. Regarding the CBC, the majority of patients had hemoglobin below 10 g / dl (73%), leukocyte count less than 10.000/μL (60%) and platelet count below 150.000/μL (83%). Chromosomal abnormalities were observed in 64% of all patients, where hyperdiploidy was the most common numerical change (67%), followed by hypodiploid (33%). All these data are in agreement with the literature. Moreover, complexes structural and/or number changes not yet described in literature were observed, which indicated poor prognosis. Finally, we concluded that this study demonstrated the importance of cytogenetic study in the diagnosis and identification of prognostic factors in pediatric patients with ALL in Rio Grande do Norte. The results obtained in this study are extremely useful and emphasizes that surveys of this nature must be conducted more frequently in our state

This article is about a study about the training needs for teachers of elementary school in the field of Geography. It is our objective to grasp their conceptions of training needs and reflect about their formative needs to teach geography. We consider the training as reflective process that involves the movement of changes and improvement beyond of formal learning, considering its numerous dimensions. We reflected about formative needs in light of the readings of Rodrigues Esteves (1993), Silva (2000), Roberts (2006), Vieira (2010). The discussions about conceptions were based on Ferreira (2007). The empirical reference constitutes to a private school in the city of Ceará-Mirim/RN, SECAT Centro de Ensino. The social subjects of our research are five teachers who work in the initial years of elementary school. We resorted a survey (auto) biographical, based on the studies of Passeggi (2011), Delory (2008), Bertaux (2010) e Josso (2010), since it is our intention to turn to the historicity of the subject and the learning, recognizing the links between him and the world and the experiences based on for learning and adult training. As technical and methodological procedure we will use the Training Narratives, whose application allows the understanding of memories and stories of schooling teachers, since are reported events occurred during the development of the individual through seminars Biographical. We observed on the narratives constructed by the teachers the absence assignments of meanings to a reworking of the theoretical formative needs and questions of its organizing principles. However, we notice the teachers were able to develop senses and means to conceive the phenomenon in study, in a descriptive way, through articulated enunciations, including aspects and opportunities linked to their teaching practices and future formative prospects. Regarding School Geography, we based our studies in the reflections of Smith Junior (1994, 2000), Tonini (2003), Vesentini (2004) and Vlach (1991), among others. We verified that the needs evidenced by the teachers to teach geography were constructed from the contexts of their teaching practices present in their school and professional trajectories. Therefore, we noticed the need for formal pedagogical qualification so that we can conceive the phenomenon in study beyond its descriptive character, understanding that it is necessary to point out reflections and questions about the dynamics of production of global capital, which conveys its interests in the contexts that often emerge formative needs of the educational system

The fishes of the order Perciformes are characterized as an important model for understanding the genetic structure of marine populations, because besides they present examples of conservation chromosomal, also they present the karyotype diversification for some groups. Gobiidae family is the most specious in the marine environment. Among its representatives, many species are part of a cryptic fauna little noticed and studied, a wide distribution with behavioral and reproductive characteristics, that make them conducive to the action of biogeographical barriers. Morphologically this family presents reduced body structures through simplification and regressions. Despite their importance in evolutionary inferences, cytogenetics data are incipient facing their species diversity, especially with western Atlantic species. In order to estimate the evolutionary diversity in Gobiidae, it were developed cytogenetic analysis and the standards body, through geometric morphometrics in five species on the Brazilian coast, Coryphopterus glaucofraenum, Bathygobius mystacium, B. soporator, Ctenogobius smaragdus e C. Boleosoma. The data show significant karyotype and morphological diversity among the species. The pericentric inversions and mergers play an important role in chromosomal evolution of this family, causing karyotypic structural and numerical differences in all species. Karyotypic and morphological comparisons among geographic samples of B. soporator from the coast of Maranhão, Rio Grande do Norte and Bahia showed cytogenetics patterns commons, but different morphological patterns. A sample from the Atol das Rocas revealed conspicuous morphological and karyotypic differentiation of another continental populations, confirming the presence of a new island species. The approaches done reveal diversification consistent with characteristics of a group of low vagile and largely able to environmental selection due from peculiar ecological requirements

La défense d une école inclusive dans les forums internationaux du monde entier a stimulé l adoption de politiques éducationnelles d inclusion et la pratique d inclusion dans les écoles, de sorte à ce que la scolarisation des élèves aux besoins éducatifs spéciaux dans les classes comunes est devenue une réalité dans la majorité des systèmes d éducation. Et pourtant, l inclusion scolaire, au Brésil, avance à pas lents et pose d innombrables questions, notamment quand il s agit de l inclusion des personnes qui présentent une déficience mentale dans les niveaux d enseignement plus avancés. Basé sur ce fait, et tout en considérant que les études et recherches sur ce thème, au Brésil, sont centrées majoritairement sur l éducation enfantine et les séries initiales de l enseignement fondamental, cette étude se propose d analyser l inclusion d une élève ayant une déficience mentale, inscrite dans l Enseignement Moyen, dans une école appartenant au réseau d enseignement de l Etat, dans la ville de Natal RN. Pour répondre aux questions proposées dans cette étude nous avons fait appel aux méthodologies qualitatives, du genre Etude de Cas, et au cours de sa réalisation avons utilisé l interview demi-structurée et l observation libre dans l ambiance naturelle de l école. Ont participé de l étude, en plus de l élève qui présentait une déficience mentale, sa mère et deux segments de l école, desquels ont fait partie trois professionnels de l équipe administrative pédagogique et quatre enseignants. L analyse des données a mis en relief la résistence de l école à répondre au projet pédagogique d éducation inclusive, aspect qui a un rapport très étroit avec les spécificités de l Enseignement Moyen, la structure traditionnelle d un enseignement basé sur l idée d une classe homogène, et le bas niveau d attentes des éducateurs concernant les possibilités d apprentissage et de développement de l élève handicapée mentale. De surcroît, le manque de directives pour conduire les adaptations pédagogiques et du curriculum à l école ont rendu fragile l action des enseignants, dont le résultat est une pratique d intégration rudement malmenée. Au travers des points de refléxions suscités par cette étude, nous considérons que l inclusion des élèves qui présentent une déficience mentale doit être centrée sur une pratique pédagogique qui repousse l idée de soumettre tous les élèves à des procédures universelles cristalisées sur des pratiques imposées par les contraintes d homogénéisation, et qui, contrairement, puisse trouver à l école des conditions favorables au développement de chacun, au travers des processus d apprentissages formés par des instances de médiation et d interaction sociales

Les récits sur les expériences de vie se constituent en apprentissages signifiants dans le processus d´ auto-formation des éducateurs. La formation est un phenomène qui extrapôle l ambiance scolaire, incluant les expériences qui servent de matrice pour la construction de la connaissance au long de la vie. Dans cette perspective, «la connaissance de soi», telle quelle proposée par SOUZA, NOVOA et JOSSO, est la notion centrale au tour de laquelle se développe cette dissertation. La recherche a comme idée principale transposer pour la realité des professeurs l´exercice reflexif de son enseignement, médiant la redécouverte de ses expériences de vie, a travers des histoires de soi que, potentialisés, peuvent transformer ses pratiques dans la classe scolaire. Je prends comme point de départ mes propres expériences comme éducatrice assumant la conviction de la indissociation entre sujet et objet de la connaissance, comme propose Édgar Morin pour parler de la science de la complexité. Je fais aussi l´usage des récits de six professeurs du réseau publique de l enseigment, révélateurs de la construction de la connaissance appuyée dans la cohérence de la praxis pédagogique avec son mode de comprendre et sentir le monde. Les oeuvres «Mes Démons» d Édgar Morin, «O Tempo e Eu» de Luis da Câmara Cascudo et «O Banquete dos Deuses» de Daniel Munduruku, ont élargit le champs des récits d expériences que se constituent en matrices des processus de formation. Le travail avec les récits de formation démontrent qu´à partir de la réflection du sujet sur sa propre expérience, il est possible de se projéter des nouvelles configurations de la connaissance tenant comme base, la reliaison entre vie, idées, et pratiques pédagogiques. À partir de la métaphore du bûcher il est possible de se comprendre la force de combustion des expériences de vie dans la formation des enseignants
