Criptografia: uma proposta para a educação básica

Abstract

The teaching of mathematics presents numerous challenges, among them, the motivation to learn concepts considered abstract. In this sense, Cryptography presents itself as something new and motivating, allowing the relation with concepts of Basic Education, as prime numbers and divisibility in integers, because it uses these concepts for the development of its algorithms. This work aimed to motivate teachers, and through them students, to the study of Cryptography relating it to Arithmetic. The aim was to contribute to the training of teachers in order to help them stimulate learning and arouse the interest of teachers and students in the content of arithmetic, with the purpose of overcoming the difficulties and challenges that teaching presents. The research happened with the deepening of mathematical concepts, the study of Cryptography, through a qualitative approach resulting in a workshop that was applied to Mathematics teachers of Basic Education. The author presented through this workshop some ideas about how Cryptography can be introduced in the classroom in order to motivate students to study Arithmetic. The results were satisfactory and showed the applicability of the activities in the classroom.
