Modelagem & linguagem cient?fica no ensino m?dio / Modelagem e linguagem cient?fica no ensino m?dio

No. of bitstreams: 1 TES_MORGANA_SCHELLER_COMPLETO.pdf: 2045628 bytes, checksum: 38593c406d21c8f8a391ef85c0364d2c (MD5) Previous issue date: 2017-03-20 / This research aims to study the Scientific Language of high school students, expressed in the written productions in order to specify to what extent Mathematical Modeling contributes to the development of the Scientific Language. For this purpose, the procedures of Educational Research Mapping were used, constituting four Maps: identification, theoretical, field and analysis. The theoretical map, constituted of theoretical references, explains about Modelling Mathematical, Language and Scientific Language, theoretical contributions of both empirical and analytic base. Language is understood as one of the semiotic systems, these that make a culture distinguish itself from the others because it acts as a codification system for others. The field map, composed from a survey about the production of the Scientific Initiation in a High School public institution, contains 10 productions elaborated between 2004 and 2012, in which Modelling Mathematical was used in the process. From them, fragments were extracted in order to constitute the Guide Map of each production, organized in the three phases of Modelling Mathematical. For the data analysis, four categories were chosen: linguistic aspects and mathematical aspects: technical taxonomy, semantic-grammatical processes, visual representations and mathematical literacy. The results and discussion are contained in the analysis Map. The results indicate that students make use of scientific language in the expression of the process of Modelling Mathematical using simultaneously linguistic aspects and mathematical aspects, both complementary in the production of meanings. In textual construction, permeated with semiotic resources, they make use of languages whose distinct functions preponderate, that is, they add another meaning to the existing one. The development of the skills related to mathematical and scientific literacy was perceived. Thus, through the use of measures of association and data correlation and standardized score, five of the productions obtained general performance (average of four categories) above the average score of high school students, thus characterizing the use of the Scientific Language. Thus, it is defended the thesis that Mathematical Modeling contributes to the development of the Scientific Language of High School students since the competent implementation of the mathematical meaning in the context was evidenced, when verbal expression and visual representations were used in a way interdependent. / Esta pesquisa objetiva analisar a Linguagem Cient?fica de estudantes do Ensino M?dio Integrado expressa nas produ??es escritas a fim de especificar em que medida a Modelagem Matem?tica contribui para o desenvolvimento da Linguagem Cient?fica. Para isso se utilizou os procedimentos do Mapeamento na Pesquisa Educacional, constituindo assim quatro Mapas: de Identifica??o; o Te?rico; de Campo; e o de An?lise. O Mapa Te?rico se constitui de referenciais que versam sobre Modelagem Matem?tica, Linguagem e Linguagem Cient?fica, aportes te?ricos de base emp?rica e anal?tica. A linguagem ? entendida como um dos sistemas semi?ticos que se constituem em uma cultura distinguindo-se dos demais, pois atua como sistema de codifica??o para os outros. O Mapa de Campo, composto a partir de um levantamento de produ??es oriundas da Inicia??o Cient?fica de uma Institui??o p?blica de ensino integrado, cont?m dez produ??es elaboradas no per?odo entre 2004 e 2012, nas quais h? utiliza??o de Modelagem Matem?tica no processo. Extra?ram-se delas fragmentos de modo a constituir o Mapa-guia de cada produ??o, organizados nas tr?s fases da Modelagem Matem?tica. Para an?lise dos dados elegeram-se quatro categorias contemplando aspectos lingu?sticos e aspectos matem?ticos: taxonomia t?cnica, processos sem?ntico-gramaticais, representa??es visuais e letramento matem?tico. Os resultados e discuss?o est?o contidos no Mapa de An?lise. Os resultados indicam que os estudantes fazem uso de linguagem cient?fica na express?o do processo de Modelagem Matem?tica utilizando, simultaneamente, aspectos lingu?sticos e matem?ticos que s?o complementares na produ??o de significados. Na constru??o textual, permeada de recursos semi?ticos, fazem uso de linguagens cujas fun??es distintas preponderam, ou seja, adicionam outro significado ao j? existente. Percebeu-se o desenvolvimento das habilidades relativas ao letramento matem?tico e cient?fico. Desta forma, mediante o aux?lio de medidas de associa??o e correla??o de dados e escore padronizado, cinco das produ??es obtiveram desempenho geral (m?dia das quatro categorias) acima do ?ndice m?dio dos escores, caracterizando assim o uso da Linguagem Cient?fica. Sendo assim, defende-se a tese de que a Modelagem Matem?tica contribui para o desenvolvimento da Linguagem Cient?fica de estudantes do Ensino M?dio uma vez que evidenciou-se a implanta??o competente do significado matem?tico no contexto, quando express?o verbal e representa??es visuais foram utilizados de modo interdependente.

It has for objective to show us how the researches works have influenced in the Mathematic professor s formation an how to use this knowledge into teaching. The field research was development with a group of Mathematics teachers and principals who acting at public and government high school. This research was applied in Paul?nia city, S?o Paulo state. The research has analyzed the conception of the math teachers, how they use their educational theories in theirs math classroom. This work has reveled that these teachers hadn t information and security, when they are teaching Mathematics. These studies showed us the urgent necessity of the reflections in our actual courses of Mathematics professor s formation, which well be used in the field research. / Este trabalho est? inserido na linha de pesquisa Universidade, Doc?ncia e Forma??o de Professores. Tem por objetivo buscar reflex?es sobre como o ensino com pesquisa se faz presente na forma??o do professor de Matem?tica e na sua pr?tica. A pesquisa de campo foi realizada com professores de Matem?tica, diretores e coordenadores de escola que atuam no Ensino Fundamental e M?dio, tanto na rede p?blica do Estado de S?o Paulo, como na rede municipal, todos atuantes na cidade de Paul?nia - SP. Foram analisados dados sobre a concep??o destes professores quanto ? pesquisa e ao seu uso no desenvolvimento dos trabalhos em sala de aula. Por?m, os dados obtidos revelaram uma falta de informa??o e seguran?a sobre o tema. Os estudos realizados mostram uma necessidade urgente de reflex?es sobre como est?o sendo desenvolvidos os cursos de forma??o inicial e continuada de professores para o trabalho com pesquisa.
