No presente trabalho relato pesquisa qualitativa na modalidade narrativa na qual procurei investigar em que medida as Feiras de Ciências contribuem para a formação e desenvolvimento de professores e alunos e até que ponto as Feiras de Ciências se constituem oportunidades de socialização e interação com a comunidade. Para tanto, analiso entrevistas semi-estruturadas que desenvolvi com dez professores e seis alunos, participantes da XI FEICIPA - Feira de Ciências do Estado do Pará-, que ocorreu no município de Abaetetuba PA, em dezembro de 2003. Constituíram-se também objeto de análise diários de campo e documentos referentes à realização das Feiras de Ciências no Estado do Pará. Percebo a partir do relato dos sujeitos de pesquisa diferentes oportunidades formativas advindas das experiências por eles vividas / compartilhadas em Feiras de Ciências. Acredito que as Feiras de Ciências podem contribuir para a socialização e troca de experiências de ensino-aprendizagem-conhecimentos com a comunidade, possibilitando uma ampliação da visão de mundo dos participantes, expositores e visitantes da Feira, permitindo a divulgação dos resultados das pesquisas, troca de experiências entre os pares, como forma de validação do conhecimento. Concluo colocando em evidência algumas categorias interativas emergidas das falas dos sujeitos investigados, no que tange ao ensino como/por pesquisa e as Feiras de Ciências: desenvolve a curiosidade indagadora; privilegia a opção por conteúdos socialmente significativos; contribuem para elaboração constante de questionamentos; proporciona (re) construção e socialização do conhecimento; permite a resolução de problemas reais na / da comunidade; exige tomada de decisão; proporciona desenvolvimento profissional; desenvolve a habilidade de aprender a aprender e promove (trans) formação dos sujeitos.

Este trabalho é uma pesquisa narrativa autobiográfica que busca compreender de que modo as praxeologias matemáticas por mim vivenciadas enquanto professor de matemática e aluno de cursos de formação continuada podem contribuir, impedir, ou mesmo serem neutras, na construção de uma nova praxeologia didática sobre a fórmula de resolução de equações do 2º grau no ensino fundamental. Sob a luz da teoria antropológica do didático, mais precisamente de sua dimensão cognitiva, são exploradas as noções de dinâmica praxeológica e cognitiva de uma pessoa para análise das duas fases da transposição didática interna, realizadas em uma turma da quarta etapa da EJA. Os resultados apontam que o equipamento praxeológico e o universo cognitivo relativos ao objeto matemático em questão contribuem para construção de uma nova praxeologia matemática. Mas o jeito pontual de pensar e fazer em sala de aula pode determinar as ações docentes e não permitir o fazer das conexões entre os objetos matemáticos intencionados na primeira fase da transposição didática interna sobre o objeto de estudo. Há, portanto, que se romper com esse fazer cultural pontual docente e permitir renovar o equipamento praxeológico e cognitivo do professor.

The construction of social knowledge, under the Piagetian approach, has been the target of recent research in the Brazilian context. From this perspective, this article presents preliminary data from an evolutionary study regarding the ideas of children and adolescents about not learning. Herein we present data obtained from the second methodological tool used in this research: an analysis of a story involving a situation of not learning, applied to 80 students between 06 and 16 years old. The main results indicate that most of the students surveyed tend to blame only themselves for not learning. They justify it by factors such as indifference, indiscipline, among others. Students' beliefs are also analyzed according to levels of understanding of social reality and most students presented a very elementary level of understanding.

The focus of this paper is on the construction of social knowledge according to Piagetian constructivist theory. We present data related to the ideas of children aged seven and eight years old about the role of the teacher. We observed 52 children, both male and female, immersed in two different educative environments: one considered socio-moral constructivist and the other one, traditional. The main results showed the particular processes of the individuals when they try to comprehend the surrounding reality. The only meaningful difference between the two environments studied was related to the comprehension of the necessity of formation to develop the function of a teacher. In the other aspects observed we have not found meaningful differences concerning the representations of the subjects as well as the environment in which they participated.

In the paper analyzes the process of knowledge construction in the news regarding the emergence of massive information and communication technologies. In this context, through a qualitative approach, first we examine the potential of production, dissemination, access and use information in a technocratic perspective, and secondly, the negative impacts stemming from the computed mediation, mainly linked to the complexity of policies of democratization of access to information and loss of criticality of science. The focus of this review focuses on the current model of information search and knowledge construction through the Web, outlining aspects inherent to the process in general. Similarly, envision different contributions of information science for the systematization of human knowledge, guided through the social actions of professionals working in various fields, with emphasis on the information representation and retrieval. It is hoped that work can contribute to the current thematic reflection on the production, dissemination and use of information as well as on digital inclusion policies.

Based on the Piagetian theory and on the research about the construction of Social Knowledge, this article presents the beliefs of children and adolescents regarding the resolution of a situation of not learning. Data were obtained from 80 students, between 06 and 16 years, who analyzed a story involving this issue. The main results indicate that most participants are not able think about the situation contained in the story in a more complex way, disregarding processes and elements, thus. They tend to give simplistic answers and it demonstrates the characteristics of the most elementary level of understanding of social reality. Even among the older students, a less elaborated representation of this daily social question, “to learn or not to learn”, was also preponderate.

The article presents preliminary data of a survey that aimed to investigate the beliefs of children and adolescents about not learning. A total of 80 students, aged 6 to 16 years participated of the study. Among the participants, 20 are 6 years old, 20 are 9, 20 are 12 and 20 are 16 years old. As methodological tool, it was asked the participants to draw a person that learns and another one that doesn’t learn. Data was analyzed according to the Piagetian perspective for the construction of social knowledge. The main results indicate that a significant part of the participants tend to blame the students for the result of no learning. This indicates that students are able to consider the amplitude of different dimensions of social phenomena only partially. When considering the level of understanding of social reality, it was observed that, even at older ages, participants have a very basic notion of the social world.

This research presents an investigation on the subject: Quantities and Measurements. The research is dedicated to this subject due to its importance in the school curriculum, and adopts the use of history of mathematics and investigative duties in a manner that will enable the production of knowledge by the student. Following a phenomenological orientation, we conducted field work in a public school in Guaratinguetá, with students from the 6 th grade. The analyze of data of the research, undertaken in accordance with the understanding of the texts FINI (1994), MACHADO (1994), BICUDO (1993, 2000, 2011), understanding how students construct knowledge measures. The data from field work were obtained from images recorded on video, the researcher's field diary and notes of the students. The descriptions of the data, transformed into text, had been detached the strechs most revealing for what it searchs to understand. The understood meaning through the analysis, indicates two categories: measure is to express values and measure is to compare quantities. When interpreting the open categories we understand that the student builds knowledge of measurement making comparisons
