Modelagem matemática a partir do desenvolvimento de experimentos práticos para o estudo de funções

Abstract

The Mathematical modeling, as a teaching methodology, aims to bring the mathematics taught in the classroom closer, to real situations, even enabling the learning of mathematics concepts and contents from problems proposed in other knowledge areas. The work was developed from the planning and application of a mathematical modeling proposal for the study of functions from two experiments related to problems usually discussed in Physics and Chemistry, respectively. The application took place in four classes of the first year of high school, in two public schools in Chapecó-SC city, with the participation of students of the Mathematics Course - Degree members of the Pedagogical Residency Program (PRP). Throughout the application, some evidence of modeling contributions in the learning of concepts related to functions was observed, being one of the main contributions identified is the student’s motivation to develop the proposed activities. The technological resources use also indicated contribution to the learning process, allowing approaches beyond those provided for in the school’s curriculum organization for first year students. The academics participation in the project application and in an exercise of pedagogical imagination in order to identify potentialities of the proposal was also the object of the analysis. Data collection took place through various instruments such as activities performed by students, testimonials from those involved, questionnaires, and observations and notes in the field diary. Data analysis took place in a discursive textual form, based on the collected data, according to the established categorization.
