Apresentação de congruência modular no ensino médio por meio da aritmética

Abstract

This study to have how aims to show the congruence modular high school using concepts of arithmetic and situations experienced daily by students to promote a relationship of content to practical situations. The research was conducted in the city of Aruanã - GO in State College "Dom Cândido Penso" in the 3rd grade of high school. Analysis didactic and pedagogical scholars are based on education and mathematics education as D'Ambrosio, Skovsmose, Paulo Freire and guided in the national curriculum standards for high school. The method develops an educational praxis contextualized, practical and playful, as in its application was proposed to extract information with concrete everyday objects such as books, magazines, products, identification cards, which have specific codes that distinguish each item mentioned above , which are produced strictly in relationship with the congruence modular, which verifies the existence of such codes. In addition to periodic phenomena on activities and games involving encryption, both worked on the standpoint of matching modular. This is a topic rarely worked in basic education despite being very rich, dynamic and pleasant, which offers excellent opportunities for students to obtain an assimilation of content and develop a meaningful learning.
