Resumo
Este estudo descreve a análise de uma intervenção pedagógica que visou à construção dos conceitos de função de 1o e de 2o graus por meio da experimentação. Nesse sentido, o que se buscou foram melhorias no entendimento desses conceitos, pois tem sido frequente os alunos registrarem dificuldades na compreensão dessas ideias, levando-os, muitas vezes, ao desinteresse por esses conteúdos de ensino. O propósito do trabalho foi investigar as implicações nos processos de ensino e aprendizagem decorrentes da realização de atividades experimentais, com o tema função do 1o e do 2o grau, com os alunos do Ensino Médio. O estudo foi realizado com uma turma de 1o ano do Ensino Médio, de uma escola estadual em São Luís – MA. A pesquisa foi de cunho qualitativo e caracterizou-se como um estudo de caso. A recolha de dados ocorreu pela observação dos participantes em sala de aula mediante registros escritos (questionário, relatórios, resolução de tarefas propostas e autoavaliação das práticas), complementados por depoimentos audiogravados e do diário de campo da professora pesquisadora. No decorrer desta intervenção pedagógica, os estudantes foram estimulados ao uso do computador, o que possibilitou diferentes registros de representação de modelos algébricos e geométricos a partir dos dados emergentes dos experimentos. Os principais resultados evidenciam que as ideias de função presente nos experimentos favoreceram o entendimento dos conceitos matemáticos em questão. Ressalta-se ainda que tais tarefas proporcionaram a participação efetiva da turma investigada no tocante às discussões, interpretações e compreensão dos conceitos matemáticos vinculados ao tema funções.
This study describes the analysis of an educational intervention aimed at the construction of function concepts of the 1st and 2nd degrees through experimentation. In this sense, what was sought was improvements in the understanding of these concepts, it is often the students register difficulties in understanding these ideas, leading them often to lack of interest in these teaching contents. The purpose of the study was to investigate the implications for teaching and learning processes arising from the realization of experimental activities, with the function theme of 1st and 2nd degree, with High School students. The study was conducted with a group of students of the 1st year of High School, a state school in São Luis – MA. The research was qualitative in nature and was characterized as a case study. Data collection, occurred, by observing the participants in the classroom through written records (survey, reports, motions tasks and self evaluation), complemented by taped and recorded interviews and field diary researcher professor. During this educational intervention, students were encouraged to computer use which allowed different registers of representation of algebraic and geometric patterns, from the emerging data from experiments. The main results showed that, the function of ideas present in the experiments, favored the understanding of mathematical concepts in question. It is noteworthy that, such tasks provided the effective participation of students, in regard to the discussions, interpretations and understanding of mathematical concepts related to the theme functions.
