An analysis in textbooks of mathematics of the final years of elementary school about the proposal of teaching polygons from the Van Hiele theor

Abstract

The research was mainly aimed to analyze the proposal of polygons teaching in the collection of textbooks commonly used in São Vicente Férrer municipality of Pernambuco, having as theoretical support the model proposed by van Hiele. To achieve the objective of the research was necessary identify initially by the Municipal Department of Education, textbooks commonly used in primary education II cycle. The completion of the analysis of these books was instrumental in identifying the relationship between the authors of these books and the theoretical model adopted by Van Hiele. We take also into account the recommendations of Mathematics NCPs for these education cycles. The choice of this teaching resource was considering a relevant tool and reference for teachers, especially in the activities developed in the classroom. Our theoretical foundation was supported by the model proposed by Van Hiele Adopting levels 1-5 of development of geometric thinking that can be used in the organization of various geometry content and at various levels of education. It is therefore a qualitative study based on the geometry of content analysis, especially polygons. From the analysis we found that the author, in general, proposes the study of polygons sequenced manner, ie, sets, exemplifies and only then, presents the activities.
