Resolução de problemas de divisão inexata a partir de reflexões sobre o significado do resto

Abstract: ResumoConsiderando que os invariantes lógicos da divisão envolvem as relações entre os seus termos e que o resto é um dos termos da divisão, é possível supor que uma forma de desenvolver a compreensão acerca deste conceito seja refl etir acerca do signifi cado do resto na resolução de problemas de divisão inexata. A presente investigação examinou esta possibilidade em um estudo de intervenção com crianças que apresentavam difi culdades com o conceito de divisão. Cem crianças (entre 8 e 11 anos), alunas do 4º a… Show more

“…With a more educational emphasis, Lautert and Spinillo (2015) analysed the importance of the remainder when performing division, with an intervention study carried out with 100 fourth-grade students who had difficulties with learning division. The intervention was based on solving division-based problems, in which the authors analysed the ways of dealing with the remainder and the relation between this element and the other elements of the operation.…”

“…The UFPE (Universidade Federal de Pernambuco) group has researched several areas of numerical cognition, including: how students learn division (Lautert & Spinillo, 2015); how they solve different kinds of problems (Spinillo & da Silva, 2016); and teachers´ understanding of the nature of different problems (Spinillo et al, 2016). Despite the fact that this group focuses on the application of research in classroom activities to a greater extent than the above mentioned research groups, there is no registered information about the impact of this research in schools.…”
