CHARACTERIZATION OF THE PROCESS OF PREPARING A TASK ON TRIANGLES WITH THE GEOGEBRA SOFTWARE

Abstract

Objective-to analyze the process of elaboration of a dynamic geometry task, planned collaboratively by mathematics teachers, aiming at the teaching of triangles in basic education. I studied during a permanent Continuing Training Year, associated with the use of Digital Technologies in Mathematical Education, in a state school of ABC Paulista. Three professors will participate two years ago from Fundamental Education and the authors of this article. The task is elaborated based on a theoretical model of dynamic geometry, structured around three elements and seven markers - units of analysis of this study -: frame of reference, reverse recontextualization, context of reference, distribution, structure, language use, construction, pedagogical relationship and engagement. The model allowed teachers to plan their entire task. Analytically, it is possible to evaluate the process of elaboration of the task and the final product, in a systematic way, contributing to the understanding of the schools made by the processors.
