Conceito de filosofia da educação

A filosofia da educação, para nós, será trabalhada dentro de uma visão histórica, ou seja, todos os conceitos relacionados à filosofia da educação trabalhados durante o curso são conceitos históricos, assim todos possuem uma dimensão histórica que remete ao entendimento do conceito a compreensão das condições históricas que foram responsáveis pela construção desses conceitos. É nesse sentido, que quando falamos do processo formativo não podemos deixar de nos remeter a grandes escritos que marcaram a civilização ocidental como, por exemplo, os textos de Homero, principalmente a Ilíada e a Odisséia. Devemos notar como as aventuras desses guerreiros míticos, seja Aquiles ou Ulisses, influenciaram na formação do cidadão grego, ou seja, é importante entender o modo que essas figuras foram representadas e serviram de modelo para a constituição da educação grega.

O aluno e a transição: relação entre auto-conceito e atitudes face à escola

A escola é um contexto fundamental para o desenvolvimento das crianças e adolescentes, sendo um local privilegiado para os processos de socialização e de construção de identidade colaborando para a organização do seu auto-conceito. Este contexto tanto pode propiciar experiências que favorecem sentimentos de confiança e competência, como pode actuar no sentido oposto, diminuindo o autoconceito daqueles que têm dificuldades em obter bons resultados e fazer amizades. Os percursos escolares são construídos através da experiência de vida de cada aluno. No entanto, a transição escolar é um factor com que todos os alunos têm de lidar, implicando mudanças nos papéis que desempenham, nas suas rotinas, relações e na forma como se percepcionam e percepcionam o mundo, podendo ter, por isso, repercussões nas atitudes que os alunos desenvolvem face à escola e sobre si mesmos. Deste modo é importante que, os alunos, ao transitarem de escola levem consigo uma percepção positiva sobre si e sobre as suas vivências escolares. Nesse sentido, este estudo pretendeu, através de uma abordagem descritivocorrelacional de caracter quantitativo, analisar a relação entre auto-conceito e as atitudes face à escola de modo a perceber melhor o efeito destes factores em alunos que se preparavam para transitar de ciclo de ensino. Para o efeito, foi recolhida uma amostra de 157 alunos, do 4º, 6º e 9º ano, de duas escolas da Região Autónoma da Madeira, a frequentar o ano lectivo 2011/2012 e utilizada a Piers-Harris Children’s Self-Concept Scale (PHCSCS-2) (Veiga, 2006) e o Questionário de Atitudes Face à Escola (QAFE) (Candeias & Rebelo, 2011). No que respeita aos resultados obtido, estes demonstraram que existe uma relação significativa, positiva, entre o auto-conceito e as atitudes nos três anos de escolaridade, assim como, uma diminuição nas atitudes face à aprendizagem do 6º para o 9º ano. Observou-se, também, que os rapazes apresentam índices mais elevados nas dimensões do auto-conceito “popularidade” e “ansiedade”, do que as raparigas.

Bergson: intuição e método intuitivo

Propomo-nos a mostrar que a intuição tal como aparece no pensamento de Bergson é tanto uma faculdade de conhecimento que se opõe à inteligência quanto um método filosófico constituído por procedimentos racionais, os quais a propiciam e enriquecem. Nesse sentido, ambos os aspectos da intuição estão intimamente ligados, sendo cada um imprescindível à compreensão do outro.

A Dimensão objetiva dos direitos fundamentais: conceito e sistematização

This paper is about the objective dimension of fundamental rights, aiming to present a concept well-designed for this dimension, and establish a systematic teaching of the subject, presenting the developments of this dimension of fundamental rights. The objective dimension of fundamental rights arises related to the idea of linking the state of fundamental rights, transforming these rights as the foundation and purpose of the state. It is distinguished from that perspective of the subjective dimension of fundamental rights, which includes the fundamental rights in an individual-state relationship. Under the subjective prism, rights are seen as limits required by the individual, the state intervention in the lives of individuals. A new dimension goes beyond the perspective of the rights of the individual as a mere resistance in the face of the state, assigning those rights also an active mission, which generates a series of legal repercussions. These developments or "effectiveness" the objective dimension are studied. The first consists of Binding Effectiveness, and demonstrated a new respect for fundamental rights within the state structure, which creates concepts such as "linkage of state functions fundamental rights" and "state s duty to protect". There is also the Radiant Effectiveness in which are examined topics such as the "constitutionalization of Law" and the "application of fundamental rights to particular relationships". Studies are still Procedure Effectiveness, in the case of "objectification of the mechanisms of protection of fundamental rights" and "opening of the processes of state protection of fundamental rights to public participation"

Uma análise histórico-epistemológica do conceito de grupo

This work aims to analyze the historical and epistemological development of the Group concept related to the theory on advanced mathematical thinking proposed by Dreyfus (1991). Thus it presents pedagogical resources that enable learning and teaching of algebraic structures as well as propose greater meaning of this concept in mathematical graduation programs. This study also proposes an answer to the following question: in what way a teaching approach that is centered in the Theory of Numbers and Theory of Equations is a model for the teaching of the concept of Group? To answer this question a historical reconstruction of the development of this concept is done on relating Lagrange to Cayley. This is done considering Foucault s (2007) knowledge archeology proposal theoretically reinforced by Dreyfus (1991). An exploratory research was performed in Mathematic graduation courses in Universidade Federal do Pará (UFPA) and Universidade Federal do Rio Grande do Norte (UFRN). The research aimed to evaluate the formation of concept images of the students in two algebra courses based on a traditional teaching model. Another experience was realized in algebra at UFPA and it involved historical components (MENDES, 2001a; 2001b; 2006b), the development of multiple representations (DREYFUS, 1991) as well as the formation of concept images (VINNER, 1991). The efficiency of this approach related to the extent of learning was evaluated, aiming to acknowledge the conceptual image established in student s minds. At the end, a classification based on Dreyfus (1991) was done relating the historical periods of the historical and epistemological development of group concepts in the process of representation, generalization, synthesis, and abstraction, proposed here for the teaching of algebra in Mathematics graduation course

O conceito de morte: significações de professoras dos anos iniciais do ensino fundamental

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

Um estudo sobre a concepção de paradoxo segundo o pensamento de Augustus de Morgan

This work aims to analyze the concept of "paradox" posed in the work of The Budget Paradox (1872) of mathematical and logical English Augustus De Morgan (1806-1871). Here it is important to note that a large part of this book consists of re-prints of a series of writings by the author in journal Athenaeum, where its performance as auditor of literature. The tests refer to some scientific work produced between the years 1489 and 1866 and the rules of selection for the composition of the work is, basically, the methodological aspects used in the completion or disclosed by such scholars. The concept of paradox is presented in two distinct moments. At first, we found a study of definitions for the term in a philosophical approach, characterizing it as something that requires further investigation; which was complemented with the classic examples of a scientific context. In the second, we present a concept advocated by De Morgan and, under this perspective, that he conceptualized the "paradox" is directly related to the non-usual methods employed in the formulation of new scientific theories. In this study some of these scientific concepts are detailed, where, through the redemption history, engaging in issues of our study Mathematics, Physics, of Logic, among others. Possession of the preliminary analysis and comparison with the design of De Morgan, it became possible to diagnose some limitations in the conceptualization suggested by the author. Further, evidenced, in front of the cases, the nonlinearity of the process of production of knowledge and hence the progress of science

Um estudo da aplicação do conceito de risco na conscientização e conhecimento de estudantes de ensino técnico sobre riscos de segurança e saúde ocupacional em laboratório de soldagem

This dissertation presents a discussion on the level of risk awareness of students who have welding practice in the laboratories at CEFET/PI, both in Teresina and Floriano. Its main goal is to investigate risk factors involving students, teachers and employees that work in these laboratories. It s an empirical survey, held among a certain amount of students from the course in Mechanic Technology. For data analysis, the concept of risk was compared to the students direct measure of perception. The main results suggest the students must be better informed, more risk aware and more competent, in order to avoid accidents. They also point to a strong need for a more formal and effective performance to assure full consciousness about the risks involving the welding practice.

Utilização de subprodutos de origem animal em dietas para frangos de corte com base no conceito de proteínas bruta e ideal, no período de 43 a 49 dias de idade

Foi conduzido um experimento para avaliar a utilização de subprodutos de origem animal em rações para frangos de corte, formuladas com base nas proteínas bruta e ideal no período de 43 a 49 dias de idade. Foram utilizados 600 frangos machos distribuídos em arranjo fatorial 2x2+1, com duas fontes de proteína de origem animal (farinha de vísceras de aves e farinha de sangue bovino), dois conceitos de formulação (proteínas bruta e ideal) e uma ração testemunha à base de milho e de farelo de soja, com quatro repetições cada. As características avaliadas foram ganho de peso, consumo de ração, conversão alimentar, rendimento de carcaça, peito e porcentagem de gordura abdominal. Os melhores ganho em peso e conversão alimentar foram obtidos quando a dieta à base de milho e farelo de soja foi utilizada. As farinhas de vísceras e de sangue e os conceitos de formulação não exerceram influência sobre as características avaliadas.

Investigação histórica na formação de professores de matemática: um estudo centrado no conceito de função

In this study we analyzed the development of a teaching experience, involving students with a bachelor s degree in mathematics from UFRN, based on the history of mathematics and mathematical investigations with the aim of contributing to the improvement of the teaching-learning of mathematics. The historical investigation tasks were planned and applied in the classroom, focusing on functional thought. The results obtained during the experience were described and evaluated based on authors who support the assumption of investigation and history as an alternative to the learning of mathematics. We emphasize that the material of analysis consisted of a work diary, audio recordings, questionnaires with testimony of the students involved, and, in addition, the assessment of the teacher of that subject. With regard to the mathematical content, the study was restricted to the concept of function, forms of representation and notation. It was evident that students showed great improvement with regard to the necessary formalization of the mathematical contents which were focused on, and to the active involvement of the students at different stages of the study. We can affirm that the completed study certainly represents significant contributions to an approach in the teaching-learning of functional thought

O uso pedagógico de uma seqüência didática para a aquisição de algumas idéias relacionadas ao conceito de números complexos

The aim of the present work is to contribute to the teaching-learning process in Mathematics through an alternative which tries to motivate the student so that he/she will learn the basic concepts of Complex Numbers and realize that they are not pointless. Therefore, this work s general objective is to construct a didactic sequence which contains structured activities that intends to build up, in each student s thought, the concept of Complex Numbers. The didactic sequence is initially based on a review of the main historical aspects which begot the construction of those numbers. Based on these aspects, and the theories of Richard Skemp, was elaborated a sequence of structured activities linked with Maths history, having the solution of quadratic equations as a main starting point. This should make learning more accessible, because this concept permeates the students previous work and, thus, they should be more familiar with it. The methodological intervention began with the application of that sequence of activities with grade students in public schools who did not yet know the concept of Complex Numbers. It was performed in three phases: a draft study, a draft study II and the final study. Each phase was applied in a different institution, where the classes were randomly divided into groups and each group would discuss and write down the concepts they had developed about Complex Numbers. We also use of another instrument of analysis which consisted of a recorded interview of a semi-structured type, trying to find out the ways the students thought in order to construct their own concepts, i.e. the solutions of the previous activity. Their ideas about Complex Numbers were categorized according to their similarities and then analyzed. The results of the analysis show that the concepts constructed by the students were pertinent and that they complemented each other this supports the conclusion that the use of structured activities is an efficient alternative for the teaching of mathematics
