O ensino de matemática financeira: juros simples e compostos com auxílio da calculadora científica

Abstract

This article raises the question of the teaching of simple and compound interest which is not given due importance in schools, since the subject is of paramount importance in the daily life of students and people in general, and should be given more focus in the curricula in primary and secondary education in Brazil. The objective of this research is to verify if the use of the scientific calculator by the students in the learning of simple and compound interest will be beneficial or not for them, and will also be taken their opinion about the use of the same during the lessons. First, an initial diagnosis will be applied to know the students' level of knowledge regarding simple and compound interest. Once this is done, classes will be taught for two groups of students, the first group using the calculator during classes and the second group without the use of the calculator, to finally apply a final questionnaire and thus verify which of the two groups obtained a better performance and thus raise an opinion about the use of the scientific calculator in the teaching of simple and compound interest.
