Propostas de uso de calculadora em uma coleção de livro didático de matemática para os anos finais do ensino fundamental após aprovação da BNCC

Abstract

The general objective of this study was to analyze the proposals for using calculators as an auxiliary methodology in teaching Mathematics in the final years of Elementary School, in the 6th to 9th grade books from Dante's textbook collection, called “Teláris”, published after the approval of the National Common Curricular Base (BNCC) (Brazil, 2018). The use of calculators has been discussed for some time and is present in some BNCC skills in the area of Mathematics. Our research work is qualitative, bibliographic, and we based ourselves on authors such as Farias, Romanello and Domingues (2018); Luna and Lins (2017) and Silveira, Abreu and Andrade (2022) who deal with the topic and also the BNCC document. In the 6th grade book, we found a greater number of activities focused on the topic, with instructions on how to use the calculator correctly. In the books for the 7th to 9th grades, the activities are fewer in number, but at an acceptable frequency. We conclude that the proposed use of the calculator in the textbooks analyzed is significant in the collection analyzed, which follows the guidelines of the BNCC, even though there are no skills in the 8th and 9th grades that directly guide the use of the calculator, but they mention digital technologies, in which calculators are inserted. Most of the proposed activities involving the use of the calculator in the Dante collection involve checking calculations performed through other calculation strategies from a self-assessment perspective, and there are few activities of an exploratory nature or analysis of patterns aimed at generalizations, which expand the creative use of the calculator.
