A UTILIZAÇÃO DA CRIPTOGRAFIA NO ENSINO DE FUNÇÕES NA EDUCAÇÃO BÁSICA

Abstract

Cryptography has been present since ancient times with the aim of sending messages that only the sender and the recipient could understand. To this end, cryptography has evolved, from Caesar's cipher to the present day with computers. Thus, this work primarily aims to approach mathematics in a contextualized way in the study of functions through the use of cryptography concepts. In this sense, the research has as its general objective to carry out a study on the implementation of cryptography in the teaching of functions and to verify the possible results. The field research scenario will take place at IFPI on the São João do Piauí campus with students in the 3rd year of technical courses integrated with high school in administration. For this purpose, a questionnaire containing questions about domain, image, zero of the function was applied. Subsequently, a pedagogical proposal of such contents was made through cryptography in order to analyze the possible results. With such a proposal, an improvement in the teaching-learning process in mathematics classes in the contents of functions was expected.
