Música, filosofia, formação: por uma escuta sensível do mundo

La musique, plus qu`um mot et le texte écrit, a le pouvoir de produire le déplacement du sujet en relation aux contingences du temps e de l´espace. Entendre de la musique est plus que de l´amusement. Comme un artifice cognitif qui ultrapasse l´expérience analytique e métonymique, les formes tonales doublent la réalité, expandent les sens, actionent l´imagination, retotalisent les sentiments, amplient les expériences, permettent la rencontre du sujet avec les éssences des phénomènes qui ne sont pas traductibles par les mots. Nous écoutons de la musique pour restituer notre dignité e conférer à la vie plus de vérité, plus de concrétion (Santiago Kovadloff). La mélodie permet l´expérimentation des états de cohésion, de conéction pleine entre sens et intention, entre commencement et fin, de la finitude de la vie (Schopenhauer). Le phénomène musical provoque l´expréssion de la douleur, de la souffrance et, au même temps, du jubile et de la joie, réliant nature et homme (Nietzsche). Tenant comme base cette compréhension, la dissertation tient dans la musique une importante métaphore pour comprendre la complexité humaine, une fois qu´elle propicie une écoute sensible du monde et mobilise dans le sujet l´expérimentation de divers états de l´être. Nous pouvons dire que la musique est un opérateur de la conaissence parce qu´elle fait affleurer l´écoute intérieure, la rencontre du sujet avec lui même. Cet opérateur cognitif actione les pôles de l´ésprit qui font dialoguer sensibilité, éthique et esthétique, ordre et chaos, silence et bruit, mouvement et pause, repétition et inovation. Par l´expérience musicale, nous habitons des formes hibrides de sensibilité et raison. L´inachèvement, notre principal caractéristique comme humains, a, dans la musique, une image impair, parce que la musique est l´expression du dévir. Pour tisser ces arguments, la dissertation part des études de Schopenhauer et Nietzsche sur la musique, esthétique et métaphysique; Expose des fragments de la biographie de trois grands penseurs contemporains (Werner Heinsenberg, Ilya Prigogine et Edgar Morin) accentuant la présence de la musique en ses vies; et, par fin, présente ce que nous appelons biographies sonores de quatre artistes-musiciens brésiliens (Benedito Juarez et Gil Jardim, de São Paulo, et Ronaldo Ferreira de Lima et, Cleudo Freire, du Rio Grande do Norte)

Estudos da relação entre fromaçãodocente e desenvolvimento do pensamento: redimensionando o olhares

Este trabajo trata de un estudio sobre la relación entre la formación continuada de los profesores y el desarrollo del pensamiento teórico. Es nuestro objetivo comprender la relación entre la formación profesional de los profesores de los años iniciales de la Enseñanza Primaria y el desarrollo de su pensamiento. En términos específicos pretendemos reconstruir los procesos formativos de las profesoras, identificando sus necesidades y los elementos que interfieren en su práctica pedagógica; diagnosticar la fase del desenvolvimiento del pensamiento y dar inicio al proceso formativo de desenvolvimiento del pensamiento; además de analizar la conexión entre ese proceso y la elaboración conceptual, tomando como referencia el concepto de pensamiento. La referencia empírica se constituye de profesoras de la Escuela Municipal Professor Arnaldo Monteiro Natal/RN, que actúan en los grados iniciales de la Enseñanza Primaria y da Educación Infantil. Para desencadenar el proceso investigativo utilizamos como referencial teórico el materialismo histórico-dialéctico como método para análisis de los fenómenos, por entender que a través de esa lógica es que podremos buscar los elementos que nos darán sustentación a una mediación pedagógica que puede posibilitar mayor eficacia en la comprensión de los fenómenos. Recorreremos a pesquisa colaborativa, una vez que es nuestra intención desenvolver una acción investigativa compartida, teniendo en vista buscar medios para resolver los problemas que la práctica pedagógica nos impone. La investigación colaborativa posibilita al sujeto partícipe reflexionar, ser investigador y co-constructor da su práctica. Así, algunos procedimientos metodológicos fueron considerados adecuados para que pudiésemos alcanzar los resultados deseados, como Reuniones, Sondeado Diagnóstica, Ciclos de Estudios Reflexivos, Sesiones Reflexivas y la Autobiografía de Formación. Ni todas las profesoras están en el nivel de elaboración conceptual, en función del proceso vivido a lo largo de nuestras vidas, aún así, toda a trayectoria de la pesquisa posibilitó la descubierta de aspectos significativa sobre nuestro objeto de investigación. Para hacer el análisis de ese proceso nos utilizamos de las teorías de Vigotski, Guetmanova, Kopnin, Rubinstein. Podemos decir que, en la perspectiva de la colaboración, la reflexión sobre la práctica puede desencadenar una nueva mirada del profesor sobre su proceso de formación, el desenvolvimiento de su pensamiento y la acción desarrollada con su alumno. No fue posible verificar, en la práctica, los resultados de nuestro trabajo, ya que, ese no era nuestro objetivo, mas nuestras fallas presentan mudanzas teóricas significativas. Entretanto, resaltamos que las conclusiones a que llegamos están lejos que se acaben , una vez que es un tema complejo, que puede posibilitar el surgimiento de nuevos estudios, de nuevas pesquisas, de nuevos conocimientos

Redes de educação ambiental: um meio como proposta pedagógica para o mundo entrelaçado

The networks terminology has been growing in different meanings, in which emergent structures coming from one not so recently typology aquired, in the 90 s, fluid shapes impelled by waves without borders of the New Information and Communication Technologies. Ever since, the pattern and the morphology are being multiply and strengthen. With this backdrop, this study deals with the Education for Environment Networks, as a political and social, educative and cultural alternative intervention, as an answer for some contemporary demands. But what are these networks? In wich way they organize themselves to germinate political actions? Where is the core of these actions? What are their limits or potentialities? These are some of the questions that are presented along the study proposed. Therefore, we have in view to unveil the network social and environmental pedagogic dimension, as an alternative proposal towards to the planetary cintzenship formation for persons and coletivity. The study employs the exploration reasearch as the analysis of the organizational reference basis and the dinamics of conections that support the dialogue among the groups that belong to the Education for Environment Networks. We conclude that the networks overcome themselves as a powerfull tool to articulate and moblize people. They establish a potential pedagogic act for political and social intervention, as an alternative proposal for the citizen formation and his world vision. We sinalize that the networks are sometimes limited by the poorness of knowledge that still remains on those who find themselves twisted on them, and on the decreasing optics by those who are absent.

Ensinamentos do barro : conversas com Francisco Brennand

El concepto de paisaje, caracterizado por la colaboración de distintos dominios cognitivos, atraviesa campos disciplinarios y formas de estructurar la producción de conocimiento a través del Arte. Para Cauquelin (2007), la representación occidental de la mirada paisajística es siempre una mirada estética que indica una conexión inseparable de la forma percibida con la forma sentida. Esa mirada estética recuerda al hombre su condición bioantropológica. En ese sentido, entiendo que un paisaje se presenta como un medio donde el humano puede ejercer su singularidad poética, transitando, así, por campos o capas de conocimientos diversos capaces de ampliar su visión rearticuladora del mundo. Motivada por esa percepción, elegí como campo empírico el Museo Taller de Cerámica Francisco Brennand, en Recife, Pernambuco. Reconstruido por el artista, el lugar, injertado de recuerdos de la infancia, pasa a abrigar, a partir de 1971, el conjunto de su obra de cerámica y pintórica. La frecuentación del artista transformó la estrategia metodológica de la entrevista en sabias y agradables conversaciones, que me proporcionaron la experiencia de otras posibilidades de enfoque durante la realización de la investigación. El objetivo de la investigación es ampliar las relaciones conceptuales entre paisaje y representación, en el sentido de privilegiar a la imaginación creativa. Tomé al paisaje como una metáfora y como un operador cognitivo, imprescindibles para el aprendizaje de la condición humana. Compartir estrategias a la vez complementares y recíprocas es lo que proponen Almeida (2009) y Morin con vistas a volver a enlazar la cultura científica y la cultura humanística, en un metodo mestizo y bricoleur que es necesaria para una reforma del pensamiento que lleva en cuenta el ensueño de la materia propuesto por Bachelard (2008). El arte se convierte, así, en un operador cognitivo capaz de promover cambios en el contexto de la educación, en dirección a una pedagogía con base compleja, como propone Pereira (1999)

Atenção, consciência e prática pedagógica: um estudo de suas interconexões

This thesis entitled, Attention, Consciousness and Practice of Teaching: A Study of its Interconnects, argues about a relationship between development of attention and consciousness and its connection to the pedagogical practice developed in a public elementary school in Natal city, Rio Grande do Norte state. The research school is located in the south of the city. School activities are developed according with the political pedagogical project. The group investigated was 25 students aged between 8-12 years of the fourth grade. The students of the research are residents of Ponta Negra village, Pirangi and Neópolis districts. The research was effected by three teachers however, the purpose of this thesis was to investigate the relationship between the development of attention and awareness and the pedagogical practice of one of the teachers who participated in the research, and more specifically understand the psychic procedures involved in the development of attention and awareness; enabling conditions for the realization of an educational action that enables the development in terms of focused attention and states of consciousness of students, analyzing their interrelations. Therefore, it was used as methodology the collaborative research by providing elements for research as strategy of formation and development, the coproduction of knowledge, and the change of educational practice through reflective processes effected through the collaboration and critical reflection among participants. For empirical construction, it was used the following procedural elements: meeting, planning, diagnosis of attention and awareness, reflective period studies, collaborative observation and reflection sessions with the participant teachers and the students. The diagnosis of attention was effected through a game and its elaboration was based on the study proposed by Luria (1991). The purpose of the game was to apprehend the stage where students were in relation of a development attention. Concerning the diagnosis of consciousness, it was taken as reference studies by Burlatski (1987), Pinto (1960a, 1960b), Rubinstien (1973), Leontiev (1978) and others studies discussing this topic. As a method of analysis, it was resorted to the dialectical historical materialism, the ability to identify, analyze and explain those contradictions generated in the process. In the analysis procedures were prepared some categories as well as, were used categories by other authors with the purpose of understanding the critical reflective process collaborative evidencing the formation of concepts and pedagogical practice of the participants, and the analysis of a practical pedagogical of a teacher and her relationships with the development of the psychic process and functions of students, in other words, attention and awareness. Regarding the reflective process were used the categories: technical reflection, critical reflection and practical reflection (LIBERALI, 2008). Concerning the analysis of the concepts were used the categories: description, characterization, definition and conceptualization (FERREIRA, 2003). And for critical collaboration were the categories: critical collaboration, uncritical, technique and practice. In pedagogical practice, were used categories: repetitive practice teaching, heterogeneous and reflexive critical (SOUZA, 2010). During the collaborative observation was evident predominance of heterogeneous practice, because the main participant teacher searches for immediate solution to the situations problem, as well as reflection moments, is the technical arrangement, practice, critical, as well as concern in interacting with students, the qualitative changes, deep knowledge, renewal and transformation of the teaching activity. In this process, the collaborative reflection proved to be an effective strategy for developing awareness of students, because through reflection sessions, the students were able to understand that learning is a building process and that it necessary to be careful for their development

Técnicas de simplificação de redes e otimização multiobjetivo para análise de variações de tensão em regime permanente provocadas por parques eólicos integrados ao sistema elétrico

This study presents a description of the development model of a representation of simplified grid applied in hybrid load flow for calculation of the voltage variations in a steady-state caused by the wind farm on power system. Also, it proposes an optimal load-flow able to control power factor on connection bar and to minimize the loss. The analysis process on system, led by the wind producer, it has as base given technician supplied by the grid. So, the propose model to the simplification of the grid that allows the necessity of some knowledge only about the data referring the internal network, that is, the part of the network that interests in the analysis. In this way, it is intended to supply forms for the auxiliary in the systematization of the relations between the sector agents. The model for simplified network proposed identifies the internal network, external network and the buses of boulders from a study of vulnerability of the network, attributing them floating liquid powers attributing slack models. It was opted to apply the presented model in Newton-Raphson and a hybrid load flow, composed by The Gauss-Seidel method Zbarra and Summation Power. Finally, presents the results obtained to a developed computational environment of SCILAB and FORTRAN, with their respective analysis and conclusion, comparing them with the ANAREDE

Especificação e implementação de um modelo assíncrono para replicação, propagação e conciliação de bases de dados distribuídas

This graduate thesis proposes a model to asynchronously replicate heterogeneous databases. This model singularly combines -in a systematic way and in a single project -different concepts, techniques and paradigms related to the areas of database replication and management of heterogeneous databases. One of the main advantages of the replication is to allow applications to continue to process information, during time intervals when they are off the network and to trigger the database synchronization, as soon as the network connection is reestablished. Therefore, the model introduces a communication and update protocol that takes in consideration the environment of asynchronous characteristics used. As part of the work, a tool was developed in Java language, based on the model s premises in order to process, test, simulate and validate the proposed model

The performance parameters are obtained through the use of software tools Ekiga, Iperf and Wimanager that assure, respectvely, VoIP conection simulation, trafic network generator and metric parameters acquisition for, throughput, jitter and packt loss. The avarage delay is obtained from the measured throughput and the concept of packt virtual transmition time. The experimental data are validated based on de QoS level for each metric parameter accepted as adequated by the specialized literature

Contribuições ao método de rastreamento de máxima potência para sistemas fotovoltaicos

The scarcity of natural resources and the search for alternative energy sources promote a rapid change in the energy world. Among the renewable energy sources, solar energy is the most promising, presenting technology of greatest growth rate nowadays. Researchers around the world are seeking ways to facilitate their progress, developing technologies with higher efficiency and lower cost. As a contribution to global progress, this master thesis proposes the development of a strategy of maximum power tracking based on perturbation and observation method for photovoltaic systems. The proposed control strategy is based on active power balance of the system, with a reduced number of sensors. It also allows the PV system to act as a regulator of the power quality at the point of commom coupling (PCC), compensating the harmonic distortion and power factor of the current netw

Desenvolvimento de um sistema para aplicação dos conceitos da tecnologia cad3d-bim na indústria moveleira

In this work was developed an information system to apply the concepts of CAD3D-BIM technology for the design activities of the furniture industry. The development of this system was based in an architecture comprised of two modules: a web interface to management the metadata of models from furniture's library and the combination of three-dimensional CAD software with a specific plugin to access the information from this model. To develop this system was also used a Data Base Management System (DBMS) designed to storage the information from models in a hierarchical way, based on concepts of Group Technology (GT). The centralization of information in a single database allows the automatic availability of any changes to all participants involved in a particular project when it‟s happens. Each module from system has its own connection to this database. Finally was developed a prototype from a 3D virtual environment to help create Virtual Reality projects in the web. A study from available technologies to create 3D web applications for execution in websites was done to support this development. The interconnection between modules and the database developed allowed the assembly of a system architecture to support the construction and exhibition of projects of the furniture industry in accordance with the concepts proposed by BIM (Building Information Modeling), using as object of study the furniture industry of state of Rio Grande do Norte

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

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

Física do meio ambiente: desafios de uma disciplina focada na formação de habilidades gerais

A disciplina Física do Meio Ambiente (FMA) foi criada em 1976 no Departamento de Física Teórica e Experimental da UFRN e, atualmente, faz parte da estrutura curricular do curso de Licenciatura em Física da UFRN e é de caráter obrigatório. Tal caráter se justifica, dentre outros motivos, pelo fato de que esta disciplina representa uma boa oportunidade dos licenciandos estudarem de que forma a Física pode contribuir para a compreensão de fenômenos relativos ao nosso Meio Ambiente, sejam eles relacionados às atividades humanas ou aos fenômenos naturais propriamente ditos e que, de uma forma ou de outra, afeta a sociedade. O nosso trabalho de pesquisa teve como objetivo principal elaborar um novo programa de ensino para a disciplina de Física do Meio Ambiente adequado às necessidades da educação científica para o século XXI. A pesquisa foi conduzida inicialmente com um levantamento histórico da disciplina desde sua origem no Departamento de Física ate os dias atuais, analise dos Projetos Pedagógicos do curso de Licenciatura em Física da UFRN, revisão bibliográfica sobre as definições de competências e habilidades em um contexto de ensino e segundo o pensamento de vanguarda nesse campo de pesquisa, acompanhamento do curso durante um semestre através de aulas observacionais, aplicação de questionário para a coleta de dados e análise de alguns livros didáticos de Física do Ensino Médio. A partir do perfil ou modelo profissional para o licenciado em Física da UFRN definimos os objetivos gerais para a disciplina de FMA em termos de habilidades gerais relacionadas com as atividades que um futuro professor de Física irá desempenhar no seu dia a dia. O nosso programa de ensino foi pensado no sentido de introduzir conteúdos de didática específica ao longo da disciplina, isto é, familiarizar os professores em formação com investigação e inovação didáticas voltadas para o ensino de temas que envolvam a conexão entre Física e Meio Ambiente. Como resultado de nossa pesquisa foi proposto um novo Programa de Ensino para FMA que pode ser útil aos futuros professores desta disciplina e foi elaborado segundo uma metodologia de organização científica do processo ensino

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

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

Dificuldades na construção de gráficos de funções

This study describes about graduation s students difficulties of to draw functions graph. Specifically, we intend to observe their abilities evolution, as well as their difficulties during Calculus I subject in engineering course. For that, we show them publications about the elaboration of graphs and its difficulties in obstacle terms and some researches witch contain this subject and that it was done during postgraduate studies in mathematical education. It shows by research methodology aspects related to French didatic s mathematic and some theories of cognitive psychology considering the high value between theoretical-methodological relation that was evidenced in both theoretical conceptions about ways to understand and teach mathematic. This methodology is based on didactic engineering purpose, that consist in preliminaries analysis, conception and didactic sequence analysis prior, trials by application followed analysis up and conclusion. We had also used pedagogicals actions and analysis of results achieved, to classify types of errors made by the 2005 s students during second semester, from conceptions related to the episthemologic and didactics obstacles

Refletindo dificuldades de aprendizagem de alunos do ensino médio no estudo do equilíbrio químico

This research intends to identify the main conceptual mistakes committed by High School students when studying Chemical Equilibrium and also how the didactic books can influence in their formation. For the data - collecting we applied 150 questionnaires with 11 open questions e 4 restricted ones. Students from three different private schools in Natal-RN were used in this survey. The questionary about the book analysis tried to understand how the subject has been boarded, making it easier or not for the knowledge building. The books were chosen by being usually the most used ones at the chemistry classes in the schools in town. On the didactic book analysis we evaluated 12 items that tried to identify the clarity with which the books would bring up the subjects, the contextualization of the exercises, the analogies used, the amount and the quality of exercises, the connections between the subjects, and the retaken of important concepts. The questionary given to the students tried to get their knowledge about the concepts related to Chemical Equilibrium. The main mistakes found were: the definition of the state of equilibrium in a chemical reaction, the constant, the double headed arrow, confusions between mass and concentration, the representation of a microscopic reaction in equilibrium, partial pressure and total pressure, and the function of the catalyser. The results demonstrated a lot of insecurity or lack of knowledge about the subject when it was realized that there was a big number of blank questions and a considerable percentage of questions with conceptual errors. We concluded that those errors could be eased or even avoided if the didactic books and the teachers boarded the contents in a more conceptual form with the application of a largest number of good quality exercices, watching the building of definitions by the students, avoiding this way the formation of wrong concepts
