O uso da calculadora gráfica GeoGebra no smartphone como ferramenta para o ensino das funções exponencial e logarítmica

Abstract

This work aims to analyze the use of the Graphing Calculator GeoGebra on Smartphone in the teaching the Exponential and Logarithmic Functions, verifying the application's ability to lead the student to the definitions of these functions and to the idea of reflection, vertical translation and inverse function by viewing the behavior of their graphs. In order to analyze the application, two activities were elaborated with discursive questions that verified the influence of each parameter on the Exponential and Logarithmic function graphs and were applied to the five classes of the 1st year of High School of the Escola Estudal Prof. Anísio Teixeira. The answers obtained in the activities and the opinions of the students led us to verify that the GeoGebra Graphing Calculator was really able to facilitate the students' comprehension of the worked content, besides increasing the interest of the students, being a tool of great potential that benefits the work of the teacher and the student's learning.
