Resumo
A criptografia tem como objetivo básico, transmitir uma mensagem a um destinatário sem que outra pessoa possa conhecer seu conteúdo, para que isso ocorra usa como ferramenta os recursos matemáticas. A preocupação com a privacidade e segurança é muito antiga, ao longo do tempo muitos códigos foram usados e utilizados principalmente para proteger segredos militares. Com o advento da comunicação eletrônica, muitas atividades essenciais passaram a depender do sigilo na troca de mensagens, principalmente aquelas que envolvem transações financeiras e uso seguro da internet. O presente trabalho trata a Criptografia como ferramenta de ensino nas aulas de Matemática, tendo em vista que o ensino da matemática está cada vez mais comprometido, principalmente por conta do desinteresse dos alunos e da grande defasagem com a qual chegam no Ensino Fundamental II. Diante disto, propomos a utilização de temas que tragam significado à aprendizagem e cativem o aluno. A criptografia pode ser abordada em vários conteúdos do Ensino Fundamental e Médio, como funções e matrizes, assuntos abordados no presente trabalho. Pretendemos, com a utilização da Criptografia no ensino dos conteúdos matemáticos, proporcionar sentido prático ao conteúdo estudado de forma que a aprendizagem se torne significativa para o aluno. Apresentaremos alguns modelos de atividades que abordam o tema criptografia e poderão ser aplicados no Ensino Fundamental e no Ensino Médio.
Encryption has the basic purpose of transmitting a message to a recipient without anyone else being able to know its contents, so that this occurs using the mathematical resources as a tool. The concern with privacy and security is very old, over time many codes have been used and used mainly to protect military secrets. With the advent of electronic communication, many essential activities depend on secrecy in the exchange of messages, especially those involving financial transactions and safe use of the internet. The present work treats Cryptography as a teaching tool in Mathematics classes, considering that the teaching of mathematics is increasingly compromised, mainly due to the lack of interest of the students and the large gap with which they arrive in Elementary School II. In view of this, we propose the use of themes that bring meaning to learning and captivate the student. The cryptography can be approached in several contents of Elementary and Middle School, like functions and matrices, subjects approached in the present work. We intend, with the use of Cryptography in the teaching of mathematical contents, to provide meaning practice to the content studied so that learning becomes meaningful for the student.We will present some models of activities that approach the subject of encryption and database is not Elementary and High School.
