(Re)construção do conjunto dos Números Racionais: uma proposta pedagógica sob a luz da aprendizagem significativa

Abstract

The subject of the dissertation is a methodological proposal for the teaching of the construction of rational numbers, with respect to the operations and their main properties, based on David Ausubel's Theory of Significant Learning (TSL), which greatly contributed to the development of this theoretical model. In Chapter 1, we will approach the theory of David Ausubel, which will serve as an anchor for the constitution of rational numbers aiming at a better approach and, consequently, a better result in the teaching/learning of this mathematical object in basic school. In order to do so, we will approach the concept of TSL and then its main characteristics, which will serve as support in the implementation of (Re)construction of rational numbers. In Chapters 2 and 3, we will present the Sets of Whole Numbers and that of Rational Numbers with allinatlicinatical masoning at:witting to Ulu light of algubiait; sum:tams. Thus° cliapivis will guide the teachers of basic education as well as the undergraduate students, as they may notice in this work that our proposal does not disregard the mathematical rigor of the sets. Finally, in Chapter 4, we will construct the rational numbers as well as their operations and properties by applying the TAL and thus simplifying the teaching of this mathematical object, what we are calling the (Re)construction of rational numbers.
