Identificando dificuldades na resolução de problemas envolvendo números racionais em sua forma fracionária: um estudo de caso com uma turma do 7º ano

Abstract

The present work had as objective to identify the difficulties of the students of a class of 7th grade of elementary school, when dealing with situations of problem solving involving rational numbers in fractional form. Was elaborated a questionnaire, composed of ten questions in context, involving the operations with fractions. Through this questionnaire, we realized where students felt more difficulties when encountered with contextualized issues involving fractional numbers and thus seek a way to facilitate the learning process with respect to fractional numbers, as well as troubleshooting. The contributions of this work, in addition to the theoretical synthesis, was spread to the scientific community, the reality of school education in which the research was conducted, as well as offering the possibility to reflect on the topic of research for solving a real problem. As prospects for future research can be a didactic planning of situations that can model for matematizar a teaching of fractional numbers, attached to contextualizações situations, for greater effectiveness of the content to the demand to which it is intended. For the development of this work, we rely on the use of support materials as: PCN (BRAZIL .1998); Fernandes (2008); Junior and Castrucci (2009); PolyA (1995); Van de Walle (2009); among others.
