This Master thesis was aimed at analyzing the scientific alphabetization of students in primary and secondary education through the Mathematical Modeling in Education. The methodological procedures are divided into four stages, called maps, to know: Identification Map, Theoretical Map, Field Map and Analysis Map. Identification Map contains: data and information justifying the theme choice, the presupposition, identification of the problem, research questions, objectives and methodological procedures. Theoretical map shows the theories that supported the research concerning: Mathematical Modeling, Mathematical Modeling in Education, Scientific Alphabetization and Scientific Literacy. In the field map was performed the elaboration and application of didactic material for the collection of data and the organization of the collected materials. The data collection occurred in two stages: initially did application with four classes of first year of high school - totaling 122 students from a school in the interior of Rio Grande do Sul, being the teacher the author of this research; in sequence, was performed its modeling application with a group of volunteer students from sixth grade elementary in the same school group previous in extra-time class - this group started with 15 students and 9 concluded the activities. In analysis map was performed qualitative analysis of the data and made the interaction between the theoretical map and field map, which enabled to verify in which levels of scientific alphabetization students were in the three phases of modeling. It was found that students did not qualify only at a level during the modeling and have shown progress during the three phases of modeling.
Esta pesquisa de mestrado teve como objetivo analisar a alfabetiza??o cient?fica de estudantes de Ensino Fundamental e M?dio por meio da Modelagem Matem?tica na Educa??o. Os procedimentos metodol?gicos dividem-se em quatro etapas, denominadas Mapas, a saber: mapa de identifica??o, mapa te?rico, mapa de campo e mapa de an?lise. No mapa de identifica??o constam os dados e as informa??es que justificam a escolha do tema, o pressuposto, a identifica??o do problema, as quest?es de pesquisa, os objetivos e os procedimentos metodol?gicos. No mapa te?rico apresentam-se as teorias que deram suporte ? pesquisa referente ? Modelagem Matem?tica, Modelagem Matem?tica na Educa??o, Alfabetiza??o Cient?fica e Letramento Cient?fico. O mapa de campo disp?e da elabora??o e aplica??o do material did?tico para a coleta dos dados e a organiza??o dos materiais coletados. A coleta dos dados aconteceu em dois momentos: inicialmente, fez-se uma aplica??o com quatro turmas do 1? ano do Ensino M?dio totalizando 122 estudantes, de uma escola do interior do Rio Grande do Sul, sendo a docente a autora desta pesquisa; na sequ?ncia, realizou-se a aplica??o da mesma modela??o com um grupo de estudantes volunt?rios da 6? s?rie do Ensino Fundamental na mesma escola do grupo anterior em hor?rio extraclasse esse grupo iniciou com 15 estudantes e nove conclu?ram as atividades. No mapa de an?lise, realizou-se o estudo qualitativo dos dados e fez-se a intera??o entre o mapa te?rico e o mapa de campo, o que possibilitou verificar em quais n?veis de alfabetiza??o cient?fica os estudantes se encontravam nas tr?s fases da modela??o. Identificou-se que os estudantes n?o se classificaram apenas em um n?vel durante a modela??o e que apresentaram progressos durante as tr?s fases de modela??o.
