O uso de calculadora no ensino de matemática: uma análise na coleção de livros didáticos adotados na cidade de Jardim do Seridó – RN

Abstract

The present study aims at analyzing activities with calculators in a textbook collection of Mathematics of Elementary School, adopted in the city of Jardim do Seridó – RN - Brazil. Studies such as developed by Selva and Borba (2010), and Albergaria and Ponte (2008) point out the importance and benefits of using the calculator in the classroom for the teaching and learning process of mathematics. The methodology of the research is based on the qualitative approach, focusing the Mathematics textbook collection of the Project Teláris. We analyze the activities involving the use of the calculator and we observe that the collection presents activities that the teacher can explore concepts, check results, correct errors and develop strategies to solve problem situations. Although the collection presents, in the teacher's manual, an activity explaining how the teacher should explore the calculator, we verify that it does not contribute to most activities. Despite the limitations, the collection offers several activities with the calculator, but it is necessary that the teacher knows the potentialities and limitations of the calculator and learn to use it with confidence.
