Digital technologies in mathematics teaching and teacher training: possibilities with the QR Code Reader ; Tecnologias digitais no ensino da matemática e formação de professores: possibilidades com o QR Code Reader

This article aims to present proposals for using the QR Code reader in the classroom, based on reflections made by mathematics teachers. Considering that Digital Technologies, smartphones and applications are present in our lives, and, even more intensely, among young people. To carry out this study, a quantitative and qualitative methodology was used, with the application of a mixed questionnaire to Mathematics teachers from the public network of a certain municipality in Rio Grande do Sul. The data showed that, although most teachers cite using Digital Technologies to teach Mathematics, the index has declined sharply when it comes to smartphones, and the Qr Code is almost unknown by all teachers. On the justifications for using or not using the smartphone, it is found that it facilitates and promotes attention, but also can generate indiscipline in the classroom. However, this same audience recognizes the potential for teaching and learning in the application, which highlights the importance of training these professionals. Finally, practices such as those suggested provide a different experience than the traditional one, in line with current technological developments. This will possibly contribute to making classes more dynamic, students more motivated and a different view of mathematics. ; O presente artigo tem por objetivo apresentar propostas de uso do QR Code Reader em sala de aula, a partir de reflexões tecidas por professores de Matemática.
