Modelação matemática e geometria espacial: o ensino de prismas retos a partir da construção de embalagens

Abstract

This Work of Completion of course came to present the results of a survey conducted with twenty (20) students of one State School of the education Elementary of Jacaraú city / PB. The objective was to implement and evaluate a proposal for education that addresses the area calculation and volume of straight prisms in spatial geometry, from the packaging models, used for storage products, this such content was developed over five stages of a didactic sequence, in order to understand the characteristics present in packaging and will formulating mathematical concepts related to Plane Geometry and Spatial, focusing at prisms straight, by means of the conception of the Mathematical modelling by teaching by Biembengut and Hein (2011) as Mathematical Modelling. How we are investigating the understanding of geometry by students, we seek a means to make this process the teaching / learning of this field of mathematics more significant, from the general objective of this research and for describe our approach used for teaching straight prism, in spatial geometry, we characterize our research as exploratory and descriptive research .This work it is a case study and sought to work with these students the concepts and applications of the geometry Plana and spatial, on the analysis of packaging of different products and in building on their own of packaging. We highlight on the results of this research, which in the construction of their own packagings, the students put into of practice the concepts formulated in the steps of the didactic sequence allowing that we could verify their evolution in the development of the activities. The research findings show that the use of the theme “packaging" for teaching the prisms straight was very productive why they supported the development of mathematical concepts in this approach and showed that the students achieved satisfactory results in the understanding of these concepts, observed on the exhibition of packaging made by them. We also highlight, this theme can be used for other approaches in the mathematics, serving as a tool in teaching for teachers who will use it and as motivation for the students involved.
