Uma proposta de ensino de funções exponenciais utilizando a modelagem matemática com o exemplo da despoluição de um lago

Abstract

This article proposes a lesson for teaching exponential functions using the lake depollution model. The approach aims to optimize the teaching-learning process for 12th-grade students through mathematical modeling. The methodology includes the contextualization of the environmental pollution problem, the introduction to exponential functions, the development of a practical lesson plan applying the depollution model, and the analysis of the expected results in students' learning. With this approach, it is expected to provide a deeper understanding of mathematical concepts, as well as demonstrate their practical applications in real and everyday situations, making learning more meaningful and engaging for students.
