Uma proposta de ensino de funções exponenciais a partir de uma prática da aplicação da lei do resfriamento de Newton

Abstract

This work presents a proposal for teaching exponential functions to high school based on Newton's cooling law, seeking to associate theoretical applications with practical application, since this union is extremely important in the teaching of mathematics, as it modifies the way students analyze situations, attitudes, generating criticism and reflections in the construction of more meaningful knowledge for students. In order to stimulate the understanding of exponential functions based on the Cooling Law of a body, proposed by Newton, with an approach that is the most simple and understandable to the student, with the purpose of demonstrating how learning can become pleasurable , since we managed to reconcile theoretical applications with situations related to our daily lives. This work was developed at the Teresina - Central Campus of the Federal Institute of Education, Science and Technology / IFPI with the purpose of promoting meaningful learning, aiming to assign meaning to the students' understanding in an intuitive way.
