O desenvolvimento do raciocínio proporcional num ambiente dinâmico de geometria dinâmica: ressonância de um programa de formação contínua em matemática - m@c2

Abstract

The frequency of the m@c2 - In training Program in Mathematics with teachers in the of Elementary School of the University of Aveiro - inspired and motivated a female teacher, in partnership with former trainer, to design and implement a learning experience that could contribute to a stronger development of proportional reasoning and graphical representation of the situations in question, involving the concept of linear function. For its assessment, a study case was developed involving a group of 6th grade. Qualitative analysis of the data collected showed that the exploitation of a dynamic geometry dynamic - GeoGebra – can create conditions for the development of such understanding.
