Um Estudo da modelagem matemática na educação matemática e seu potencial para o desenvolvimento do pensamento crítico

The implementation of mathematical modeling curricula represents a great challenge, both for teachers and students, since it escapes the traditional teaching methodology, i.e. when the teacher speaks to his/her students. This work presents, at least, one possible way of implementing mathematical modeling inside the classroom, and how this way encourage critical thinking in students. I see mathematical modeling as an opportunity to minimize student's rejection and increase their interest for mathematics, promoting their competencies to give points of scene in every day situations. The history of mathematics shows that mathematical modeling had developed since almost the beginning of human live, when men needed to solve problems that arose in the course of his life. Mathematics has become more and more abstract, but it is important to recall what was originated it. In this way, it is possible to make this subject matter more meaningful to students. I will make an introduction of mathematical modeling, presenting some important definitions. Based on this framework, I will present a classroom instruction understand on a 7 th grade classroom by myself. With this in instruction I sustain the idea that mathematical modeling has, in fact, a great potential to improve the quality of mathematics teaching. I also sustain that, the development of critical thinking, as a competence, way be achieved with it

As concepções de natureza e a relação sociedade-natureza no pensamento de Monteiro Lobato

Buscou-se com o presente trabalho identificar as concepções de natureza e a relação sociedade-natureza presentes no pensamento do escritor brasileiro Monteiro Lobato. Por meio de pesquisa de natureza documental foram identificadas, predominantemente, as concepções romântica e utilitarista da natureza. Desta forma, quanto às relações sociedade-natureza delas decorrentes, em conseqüência da concepção romântica identificou-se a referência ao homem como destruidor e ser não pertencente à natureza, assim como em decorrência da concepção utilitarista percebeuse a legitimação do direito de exploração dos elementos naturais pelo ser humano. O estudo voltou-se também para a maneira como estas concepções de natureza, coexistentes no pensamento lobatiano, revelam-se ao ser discutida a questão do desenvolvimento brasileiro, causa defendida por Lobato durante sua vida, principalmente por meio das campanhas pela exploração do petróleo e ferro nacionais. Percebeu-se que ao considerar esta questão, a concepção predominante é a utilitarista, defendendo-se a exploração dos recursos para a riqueza nacional. Foram identificadas contradições nos posicionamentos de Monteiro Lobato, motivadas seja por aspectos emocionais seja pela influência do momento histórico vivido pelo escritor. Possivelmente as concepções identificadas na obra lobatiana refletem as concepções hegemônicas no momento histórico de sua produção, assim como influenciariam seus leitores na constituição de suas concepções de natureza e na maneira como estes estabeleceriam sua relação com o meio natural não-humano

Aplicação de princípios do pensamento enxuto no processo de envio e devolução de correspondências em um banco privado

The success obtained by the Toyota Company in implementing the Toyota Production System was a global case of study that generated different new approaches, such as Lean Thinking. This approach was already successfully applied to various sectors, breeding methodologies as Lean Service, Lean Office or Lean IT. In this paper, the main concepts of Lean Thinking were applied in an information flow through an action research, more specifically in the sending and return of mailing process from a bank. The objectives were to create changes that led to the decrease of the mail returning indexes and ultimately to cost reduction and waste elimination. For this purpose the actual situation was mapped, and after data collection and analysis, a future proposed state was generated for the information flow. Alongside, indicators were conceived for managing process control and a set of implemented and proposed improvements were delivered. The applied Lean Thinking concepts were considered efficient for the application, and the proposed objectives were achieved

A divulgação do pensamento saussuriano no Brasil

The ideas of Ferdinand de Saussure (1857-1913) still stimulate keen interest among language scholars today, be it complementary or contradictory. Saussurean thought has become widespread, in a more or less explicit manner, in undergraduate and graduate education in the humanities. Since the mid-1950s, Saussure’s ideas have been introduced and debated as part of the training of first-language and foreign-language teachers, communicators, anthropologists, sociologists and psychologists. In the majority of undergraduate and graduate disciplines in the areas of Linguistics and Communication, from the moment academics begin to address the nature of human signification and communication, it is impossible to ignore Saussure’s reflections on language and parole. The aim of this study is to reflect on the transmission of the general lines of Saussurean thought in Brazil. For this purpose, an inventory and analysis are carried out of Linguistics manuals originally published in Brazil since the 1970s, with the aim of reflecting on their construction in terms of programming and persuasion, categories of analysis of didactic speech proposed by A. J. Greimas.

Metamorfose: reflexões sobre o pensamento de Ignacio Assis Silva ou tentando achar o fio da meada

This text, homage to Ignacio Assis Silva, looks for the founding theoretical conceptions of his thoughts. When I looked at his texts, from the 70’s to the 90’s, my reading went through the path of an author who is always worried about revealing the birthplace of meaning. To catch this unique moment of semiosis, Silva proposes the concept of metamorphosis, a key-term which allows us to unite the two ends of his formation: Historical Grammar and Semiotic
