O Modelo Grupo Prático de Deslocamentos em Psicologia e Epistemologia Genéticas e sua Formalização

In this article, we aim to describe and explain what is the model “practical group of displacements”, introduced in 1937 by Piaget’s work La construction du reel chez l’enfant (Neuchâtel, Paris: Delachaux et Niestlé), essential to comprehension of the construction of space. To this end, we introduce the mathematical notation to describe it, we give the meaning of this notation in the child’s behavior and explains the mathematical structure of group underlying the model.

O egocentrismo infantil na perspectiva de Piaget e representações de professoras

This text comes up a clipping from an applied research, qualitative approach, which sought to understand both the egocentric second Piaget, through a literature search, furthermore, from a study that was conducted with teachers from kindergarten and the first years of elementary school, we sought to delineate the representations of such teachers in this regard and its proximity to the theory in question. Therefore, the trajectory traveled consisted of explaining aspects the Vygotsky's critique to Piaget, with respect to egocentric thought; subsequently show how as Piaget responded to criticism of Vygotsky, and expound upon the egocentric thought present in your perspective. Were addressed, we sought to delineate the representations of fifteen educators about the phenomenon of egocentrism in children and its proximity with the theory of Piaget. It might thus as regards the literature, and bring the importance of recognizing and understanding the thought egocentric in Piaget, as a phenomenon is intrinsically linked to the development of the child and that we can approach your understanding. For representations of teachers, approached more subjectively common sense than the concepts found in psychological theory focused. Thus, this study allows us to understand the limits and scope of training courses for teachers, with regard to the dimension in focus.

Proposta construtivista em questão: analise da experiencia brasileira no ensino da leitura e escrita

Years after the constructivism theory was adopted by “Parameters for National Syllabuses”, the results have pointed to a worse performance in teaching and learning with regards to reading and writing. This article presents the conclusions proceeding from investigation about the probable reasons for the student’s lack of success in reading and writing, and its relation to Emília Ferreiro’s constructivism proposals. Interviews were made as well as sit in class observation were done, with twenty teachers at six Fundamental Level 1 schools in Ourinhos, SP State, in schools that had been awarded the best and the worst performance rating in the Prova Brasil-2005, with this objective: to know and analyze the teacher’s conceptions under their practices and their practices in the classes. The conclusion is: it is not possible to attribute the students’ lack of success in reading and writing; these studies showed that many teachers, most of them, have a non-constructivist concept of teaching and learning, it means that they do not apply Ferreiro’s researches.

Função simbólica e desenvolvimento da noção temporal em surdos e ouvintes: análise na perspectiva de Jean Piaget

In a previous research, it was observed that are symbolic exchanges established between the persons and the environment they live in that allow them to interact with others, leading them to reorganize their internal cognitive structures, reaching more elaborated stages. In the case of a person with deafness, the possibility of exchange can be compromised and knowledge about the construction of the temporal notion seems to be essential to enable a path of explanation about the difficulties they have regarding their cognitive development. Thus, based on the theory of Jean Piaget, the study intended to understand how the temporal notion constitutes as possible subject to the process of building the real, and examine, through empirical evaluation, if the difficulty in establishing symbolic exchanges caused by deafness would compromise the development of this notion. For this purpose, bibliographical research and empirical research were made, by the comparative evaluating between the performance of deaf and hearing subjects in relation to the construction of temporal notion. Two groups of subjects aged between 10 and 12 years were composed: one with three deaf subjects and another with 3 listeners. The assessment and analysis of the data were based on an experiment created by Piaget and his staff. The results showed that the listeners present responses from operative level, compatible with the age range in which they found themselves. In contrast, the deaf subjects showed responses of transition level, which indicates a situation of cognitive delay. We conclude that the potential compromise linguistic presented by deaf people, can hinder the activity representative causing delay in construction of temporal notion and consequently the development of thought. We conclude that the possible linguistic committal presented by deaf people can hinder the representative activity, causing delay in construction of temporal notion and consequently in the development of thought. In this sense, it seems that the Sign Language constitutes an important tool for deaf people because it allows symbolic exchanges that favor the cognitive development.

O Sistema das Autoconsciências: da Epistemologia Genética a um Idealismo Especulativo

This paper discusses some of the general foundations of my philosophical journey, from studies, researches and reflections on the sciences and Genetic Epistemology, to the proposal of a speculative idealist metaphysics and ontology. I initially introduce the notion of a system of human beings and their behavior, in order to contextualize the discussion of one of the central questions of the paper: how can the system of human beings and their behavior be comprehended? I then make some general considerations about Genetic Epistemology and Psychology, and analyze the consequences of the thesis inherent in them that the object is an essentially intellectual being. Next, I consider the possibility of a different perspective on the Theory of Knowledge. This leads to the question “how are the different philosophic systems possible?” and to the necessity of the constitution of a philosophy that is able to deal with this question from a viewpoint of totality and on the basis of a thought able to think itself. I then make some considerations on the establishment of such a philosophy in regard to genetic epistemology, and introduce the notion of idea. Finallly, a general research project is proposed (that this paper only announces) that aims to use some concepts and arguments inspired by Hegelian Speculative Philosophy (or related to it) in order to comprehend the system of human beings and their behavior, especially in the production scenario of contemporary science and philosophy, including Genetic Epistemology. I hope I have contributed to showing that another philosophical view (distinct from Piagetian naturalism) is at least possible, one that takes into account the experimental data of Genetic Epistemology and Psychology.

O Modelo do Sistema de Esquema de Ações e Operações sobre Símbolos e Signos

The objective of this paper is to introduce a model, called the Model of the System of Schemes of Actions and Operations on Symbols and Signs (MoSSAOSS), that articulates a systemic, systematic, and synthetic view of some of the principal theoretic and experimental results obtained by Piaget and his coworkers. Here, the term model means a schematic representation of experience, the relation of whose elements can be explored by means of logic and mathematics in order to deduce properties that correspond, in a sufficiently accurate form, to direct observable empirical properties. The MoSSAOSS model is intended to reveal in an abstract and simplified form, and through explicit hypothesis and definitions, the general structure and function of the System of Schemes of Actions and Operations on Symbols and Signs. It is this system that furnishes the elements that make possible the diverse structures necessary for the knowledge of the epistemic subject, the subject of knowledge, the stages in their construction, and the attribution of significations to objects, to situations, and to the actions and operations of the subject itself.

O Caráter a priori das Estruturas Necessárias ao Conhecimento, Construídas segundo a Epistemologia Genética

In this paper we discuss the question of the a priori character of the necessary structures of knowledge according to Genetic Epistemology, focusing on the notion of space in particular. We establish some relations between Jean Piaget’s Genetic Epistemology and Immanuel Kant’s Critical Philosophy, discuss the notion of the a priori according to Kant in relation to the notion of space, and discuss the construction of the notion of space by the epistemic subject according to Genetic Epistemology, focusing on the Sensory-Motor Period. We conclude that, in Genetic Epistemology, space is still thought of as an a priori form of phenomena in the sense that the notion of space is what spatially organizes the data of perception, being the condition of perception. Furthermore, it is not directly abstracted from experience, but is constructed by the epistemic subject in its interaction with the environment, occurring with the structuring of the system of schemes of action. This analysis leads to the notion of the constructed a priori that, after its construction, has the characteristics of the a priori as conceived by Kant.

Influence of standard load micro and nanopatterned in surface roughness of bleached teeth and submitted to different surface treatments?

The aim of this study was evaluate the dental enamel after whitening treatment with Opalescence Boost PF® 38%, correlating the structural alterations in the surface of the enamel with its respective pH and verify if whitened teeth submitted to different finishing and polishing techniques show similar surface texture to healthy teeth (control group). Sixty premolars were divided in 6 groups (n = 10), which had been immersed in artificial saliva during all the experiment. Protocol whitening was performed according to the manufacturer recommendations, and then the specimens were submitted to different polishing technique with Sof-Lex Pop On® disks, Flex Diamond® felt disks using two different micrometric polishing pastes (Enamelize® and Diamond Polish®) and two nanometric polishing pastes (Lummina-E Diamond and Lummina-E Alumina), according to the groups. Representative specimens were analyzed in scanning electronic microscopy (SEM). Whitening gel used in this experiment had modified the morphologic aspect of the enamel surface. It was found that two nanometric polishing pastes (G5 and G6) promoted a less rough surface compared to control group even after the whitening process.

O perdão como componente moral em crianças do primeiro ano do ensino fundamental

Forgiveness may be considered a moral component to be developed along with the development of moral autonomy of individuals. This study aims to verify how 10 (ten) children from the first year of elementary school conceive the pardon and its possible relationship with their moral autonomy development. As theoretical research we have taken Piaget´s studies on human´s morality (1930; 1932) and Rique (2007, 2008, 2011) and Enright (1991, 1998) studies about forgiveness. This study was based on a qualitative research and the adopted method was the Piaget's Experimental Clinical Method. The results have shown that children perform moral reasoning when facing situations which involve the decision of forgiving someone and tend to comprehend forgiveness as forgiving someone for some performed act. We conclude by emphasizing the importance of the teacher’s mediation and intervention in moral discussions involving forgiveness, for the construction of the learners ´moral autonomy.

Contribuições da epistemologia genética para a construção do conhecimento na educação infantil

The kindergarten has as main objective the development of the child from zero to five years in their physical, emotional, cognitive and social domains. This is also the goal of the Centers for Children Living from the Universidade Estadual Paulista (UNESP) that caters to children of teachers, technical and administrative staff and students. In this work we report some of the action of the Technical Commission of the CCIs with reflections on the construction of children's knowledge through observations of the CCIs in different campuses of Unesp, conducted through technical visits. As a theoretical contribution we adopt the Genetic Epistemology of Jean Piaget. Partial results show that, although there are efforts to understand and assist the process of constructing knowledge of children, many challenges remain to be overcome in the realization of an excellent service to children.
