Educação financeira: aplicação de conhecimentos matemáticos para a resolução de situações-problemas

Abstract

This work is the result of a field research based on a mathematical investigation of the classroom, realized about the Financial Mathematics with the perspective of Critical Mathematic Education. This research’s objective was to investigate the standing of the students up to common financial problems and the utilization or non-use of the mathematical knowledge to take a standing. The subjects of this research are students of a 3° grade class of the high school Escola Estadual de Ensino Médio Érico Veríssimo, from Restinga Sêca. After analyzing the results it’s possible to point out that the students are missing knowledge about the interest rates in the current market, like banks interest rates, vehicle financing rates or even interest rates in the local commerce. We concluded that the way mathematical knowledge is developed in school not always prepare the student for life in our society.
