Através do uso da programação em linguagem orientada a objetos e, aplicando-se uma técnica de programação específica, é possível gerar um conjunto de classes genéricas cujos objetos representam cada bloco de um controlador fuzzy e também suas variáveis linguísticas. Tais classes, sendo aplicadas de forma sistemática, facilitam a programação de uma variedade de controladores desta natureza. Este trabalho apresenta a referida técnica e mostra os resultados obtidos através de um modelo simulado de um pêndulo rotacional invertido que é controlado por um sistema de controle composto por três controladores fuzzy, projetados e construídos sob este ponto de vista.

Esta pesquisa foi realizada com o objetivo de identificar e analisar as relações entre as linguagens da Matemática e da Informática no contexto da sala de aula, a partir da inserção das tecnologias informáticas na aprendizagem da Função Quadrática. Nesse sentido, os conceitos que envolvem a forma algébrica e forma gráfica desta função, foram observados pelos alunos ao explorar aspectos dinâmicos na interface do Geogebra. A fundamentação teórica da pesquisa, foi subsidiada pelas ideias de Pierre Lévy sobre as tecnologias da inteligência na disseminação da informação e do conhecimento, bem como pelas contribuições filosóficas de Ludwig Wittgenstein acerca do jogo de linguagem. A metodologia da pesquisa possui caráter qualitativo definido a partir de critérios específicos acerca do objeto de estudo e dos sujeitos investigados. As informações foram obtidas por meio de questões específicas aplicadas em dois momentos, a saber: antes e após a realização de um minicurso sobre o GeoGebra. As análises das questões revelaram que os aspectos visuais e os movimentos no uso do computador, estabelecem relações entre as formas algébricas e gráficas da função quadrática. Assim, eles puderam perceber que os coeficientes numéricos modificam a parábola e isso dá sentido aos conceitos estudados. O uso do GeoGebra possibilita outras formas de aprendizagem evidenciadas entre o Jogo de Linguagem da Matemática e o Jogo de Linguagem da Informática no âmbito da Educação Matemática.

Este artigo tem o objetivo de repensar conceitos, conteúdos e objetivos de temáticas ligadas à área de História através da articulação entre o uso de linguagens audiovisuais – no caso, o cinema – o papel da narrativa e a construção de práticas de ensino, todas baseadas nos estudos de micro-história. Desejamos não apenas debater os potenciais pedagógicos e empíricos dos recursos tecnológicos dentro das salas de aula, mas, especialmente, o das possibilidades reais de transformação dos alunos em sujeitos do processo de construção de novos conhecimentos na área, por meio da produção do curta metragem. Essa ferramenta pedagógica e tecnológica pode ajudar-nos a refletir sobre as prerrogativas dos PCN’s que prevem em suas propostas a valorização do local e do cotidiano dos alunos, o respeito à diversidade e pluralidade, o papel dos sujeitos na História. A proposta aqui apresentada é fruto de um projeto realizado na Fundação Educacional de Fernandópolis entre 2009 e 2010, sob a forma de trabalhos de conclusão de curso desenvolvidos por alunos do curso de graduação em História.

The relation among the concepts text, document and information is discussed, with the aim of clarifying the concept of document, with a focus in the field of economic information organization and management. A document is a medium in which information is recorded and manifested. A document is, thus, material, has a purpose, can be organized and treated for its improved dissemination, and has a specific subject and context.

Introduction: Since their first month of life, babies already show alternation in their communication, in which adults have an important role, assuming interaction turns with the child through questions known as eliciting questions. Verifying this alternation incited us to analyze children’s responsive attitudes toward the questions of the adult interlocutor. Objetives: (1) describe and characterize the kinds of responsive attitudes children have to open questions; (2) verify if there are any differences between the developed and non-developed kinds in the answers. Material and method: data were extracted from 28 interviews (recorded both in audio and in video) with four male children (5-6 years-old) who attended a public Kindergarten. Results: regarding the first objective, 88.7% of the attitudes were answers to the questions, 4.7% were non-responses and 6.6% were confirmation requests. Regarding the second objective, 48.2% of the answers were developed and 51.3%, non-developed. Conclusion: Although the high percentage of answers indicates that the children showed themselves sensitive to the demands of the adult interlocutor, the small percentage difference between developed and non-developed answers also indicates that children mostly depend on their assistance to develop their utterance since they oscillate between restricting themselves to the demand of the interlocutor and expanding it.

This paper brings notes regarding Wittgenstein’s philosophy of language and its presence in habermasian philosophy by means of the basic concept language game. The approach of language of the second Wittgenstein reaches a rather culturalist abstraction, which, however, disclaims him of the pretension of being a theoretical of language, but in Habermas, this approach is put with an intention: the systematization of the universal pragmatics, which he presents as a theory of language games.

The indexing process aims to represent synthetically the informational content of documents by a set of terms whose meanings indicate the themes or subjects treated by them. With the emergence of the Web, research in automatic indexing received major boost with the necessity of retrieving documents from this huge collection. The traditional indexing languages, used to translate the thematic content of documents in standardized terms, always proved efficient in manual indexing. Ontologies open new perspectives for research in automatic indexing, offering a computer-process able language restricted to a particular domain. The use of ontologies in the automatic indexing process allows using a specific domain language and a logical and conceptual framework to make inferences, and whose relations allow an expansion of the terms extracted directly from the text of the document. This paper presents techniques for the construction and use of ontologies in the automatic indexing process. We conclude that the use of ontologies in the indexing process allows to add not only new feature to the indexing process, but also allows us to think in new and advanced features in an information retrieval system.

In this paper we present ongoing research in which we approach the regulatory role of language in role play in children aged six and seven. In research, we seek an understanding of the relationship between language, ownership and complexity of the children's game. The hypothesis guiding the research is that the dialogical relations between children and adults and among children, while playing, contribute to children's learning game. Procedures are being used interpretive ethnographic research that focuses on the human meaning of social relations, waged by the subjects in a particular historical context and its elucidation and exposition by one researcher. This approach allows closer studies of Vygotsky and Bakhtin scholars of language that emphasize the regulatory role of language in human relationships and value the dialogic exchange between researcher and researched; active subjects of the research process. The data were produced by means of observation and interview, in a field diary records, photographs and audio recordings. They are being screened in thematic groups and analyzed using interpretative narration. The participants were two teachers and two classes of the first year of an Elementary school (EMEF) School of Municipal Elementary School Crane, State of Sao Paulo, totaling 45 subjects. Bearing in mind the above assumptions, are presented and analyzed data that allow to anticipate some results.

This paper presents the results of a study aimed at identifying and analyzing the theoretical and methodological principles that guide the practice of teachers in the early years of computer use in the teaching and learning. Specific objectives we seek to identify and analyze the social representations of teachers on the use of computers in teaching and learning. The research took a qualitative approach with a descriptive-explanatory and owned two phases of data collection: a) a questionnaire b) monitoring the daily practice of teachers in a selected school and semi-structured interview. The analysis of data was done through content analysis. Through the interrelationship of the data in the questionnaire, observation and interview, we found that the teachers surveyed have an address that does not match the teaching practice in the use of computers in the educational process. The theoretical expressed by teachers participating in the research meets constructivist beliefs and / or sociointeractionists but teaching practice thins primarily to behavioral assumptions. Observe social issues of representation when the speeches of the participating teachers did not correspond to their practices. Associated with this or as a cause of these conditions have failure, inadequacy or absence of teacher training for the use of computers in the educational process leading to under-utilization of this resource.
