Modelagem nas ciências e matemática : das ideias às expressões dos estudantes de ensino fundamental

Abstract

This research aimed to analyze the ideas of middle-school students in relation to mathematics and science, from their oral and written expressions, during the modeling process - Modeling in Education - to identify the Literacy and Scientific Competence of these students. The adopted methodological procedure consisted of four steps, called Maps. Namely: Identification map on which we present data and information justifying the choice of the research theme, objectives and methodological procedures that guide it. Theoretical map in which theories are presented on Modeling in Education, Literacy, Scientific Competence and Mental Models and, recent research synthesis to place this search in a map production; Field map in which we present the application description of the Didactic activity and the organization of empirical data from the Teaching Activity performed with two classes of 7th year of middle-school of basic education; Analysis map that shows the analysis based on six categories and stages of modeling. It was identified in the first step of modeling, perception and apprehension that students are scientifically literate, since they appear to have competence in identifying scientific issues, however, the other stages, understanding and explanation and meaning and expression, students had difficulties to achieve competence required to explain scientific phenomena and use scientific evidence, respectively. The results were satisfactory, as students advanced in terms of Literacy and Scientific Competence, even though non-linearly.
