Modelagem matemática no ensino de funções: aplicação de uma atividade para o ensino de função afim e exponencial

Abstract

In the educational field, Mathematics teachers are concerned about their students' interest in the subject, which means that different teaching strategies are explored, and Mathematical Modeling is one of them, having as its characteristic the approximation between the students' daily lives and the mathematical language. This work aims to apply an unprecedented class using modeling for teaching linear and exponential functions and to report the author's experience with a 1st grade high school class, in the city of Sobral, in the interior of Ceará. The research methodology is exploratory in nature, the target audience are students in the first year of high school and data collection will be through questionnaires. A bibliographical research is carried out to analyze the different definitions of modeling, its application in the teaching of functions and the proximity with the abilities presented by the Base Nacional Comum Curricular. After analyzing the applied activity and through the results of the questionnaires, it was found that students see mathematics as something unnecessary and out of context, but activities like this can help to improve the vision of mathematics as something connected with reality. It is concluded that Mathematical Modeling is an effective teaching strategy to improve students' interest in mathematics by linking mathematical language with everyday matters.
