Medida de comprimento: uma sequência didática na perspectiva da grandeza e medida

Abstract

This research about greatness and measures, in particular measure of length, aimed to legitimize a didactic sequence that favored the teaching of measure of length from the notion of magnitude and measure. The research was developed based on Guy Brousseau's Theory of Didactic Situations, inspired by the didactic model of Régine Douady and Marie Jeanne Perrin-Glorian, among other fundamental references for the elaboration of the didactic sequence. The approach of this research was qualitative in a methodological conception supported in the aspects of Didactic Engineering. The sequence was applied in a public school of elementary and middle, located in the metropolitan area of Belém do Pará, in a class of 25 students, from the 6th year of elementary school. The analyzes of the activities indicated that, proposing a didactic sequence that explores length in the domains of greatness and measure favors the comprehension of notions of concepts linked to greatness and measure, such as measuring, measuring need, measure, length and quantification (measure). As well as the understanding on the part of the students regarding the conversions of units of measurement and the constitution of the metric system decimal. From these results, this research generated an educational product called, didactic sequence for the teaching of length measurement.
