Contribuições do método de resolução de problemas de Polya para o ensino de função afim para alunos do 1º ano do ensino médio

Abstract

This paper presents a problem-solving proposal inspired by the guidelines of George Polya. We utilized exercises from the OBMEP question bank, which address applications related to linear functions. The aim of this study was to survey students' prior conceptions regarding linear function content and to analyze how the application of Polya's problem-solving method could contribute to the development of linear function content in the first year of high school for a more effective approach to questions on linear functions present in the OBMEP. The results indicated that the use of Polya's methodology was an effective strategy for overcoming the difficulties identified in this study. These conclusions not only enrich the understanding of teaching linear functions but also provide valuable insights for future pedagogical actions.
