Previous issue date: 2006-05-19 / The central question of the present study is to identify the epistemological knowledge that the teachers-trainees possess regarding the characteristics (properties) of the decimal numbering system; its purpose is to offer a contribution to the pedagogic practice of the teachers who work within the Basic Literacy Cycle, in terms of what concerns both the acquisition of contents and the development of the knowledge that helps them in the elaboration of adequate strategies to working with the Decimal Numbering System in the classroom. The study is based on the constructivist sociointeractionist approach to teaching Mathematics and it constitutes, in itself, a methodological intervention with the teachers-trainees engaged in the Professional Qualification Program in Basic Education of the Federal University of Rio Grande do Norte. The foundations of the study were found in investigations of researchers who had carried out studies on the construction of numerical writing, showing, for instance, that the construction process of ideas and procedures involved in groupings and changes to base 10 take a lot longer to be accomplished than one can imagine. A set of activities was then elaborated which could not only contribute to the acquisition of contents but that could also make the teachers-trainees reflect upon their teaching practices in the classroom so that in this way they will be able to elaborate more consistent didactic approaches, taking into consideration the previous knowledge of the students and also some obstacles that often appear along the way.
Even when teachers have access to the most appropriate dicactic resources, the lack of knowledge of the content and of the real meaning of that content make the Decimal Numbering System, a subject of fundamental importance, be taught most times in a mechanical way. The analisys of the discussions and behaviours of the teachers-trainees during the activities reavealed that they made them reflect upon
their current practices in the classroom and that, as a whole, the aims of each of the activities carried out with the teachers-trainers were reached / O presente estudo tem como quest?o central identificar o conhecimento epistemol?gico que os professores-alunos possuem a respeito das caracter?sticas (propriedades) do sistema de numera??o decimal, e tem como finalidade oferecer
uma contribui??o para a pr?tica pedag?gica dos professores que atuam nas turmas de Ciclo B?sico de Alfabetiza??o, tanto no que se refere ? aquisi??o de conte?dos quanto ao aprimoramento de conhecimentos que os auxiliem na elabora??o de estrat?gias adequadas para o trabalho com o Sistema de Numera??o Decimal em sala de aula. O estudo est? baseado na proposta construtivista sociointeracionista
para o ensino da Matem?tica e se constitui numa interven??o metodol?gica, com os professores-alunos ligados ao Programa de Qualifica??o Profissional para a Educa??o B?sica da Universidade Federal do Rio Grande do Norte. Buscaram-se
fontes de sustenta??o em investiga??es de pesquisadores que realizaram estudos sobre a constru??o das escritas num?ricas, mostrando, por exemplo, que o processo
de constru??o das id?ias e procedimentos envolvidos nos agrupamentos e trocas na base 10 leva muito mais tempo para ser realizado do que se pode imaginar. Foi elaborado um conjunto de atividades as quais pudessem n?o s? contribuir para a aquisi??o de conte?dos, mas fizessem os professores-alunos refletir sobre suas pr?ticas em sala de aula, para que, assim, eles pudessem elaborar propostas did?ticas mais consistentes, levando em conta os conhecimentos pr?vios dos alunos e alguns obst?culos que se interp?em nessa trajet?ria. Mesmo o professor dispondo dos mais apropriados recursos did?ticos, a falta de dom?nio do conte?do, do real
significado desse conte?do, faz com que o Sistema de Numera??o Decimal, tema de fundamental import?ncia, seja ensinado, na maioria das vezes, de forma mec?nica. A an?lise das discuss?es e o comportamento dos professores-alunos durante a realiza??o das atividades revelaram que estas provocaram reflex?es sobre as pr?ticas de sala de aula como tamb?m que, de modo geral, foram atingidos os objetivos propostos em cada atividade realizada com os professores-alunos
