| dc.description.abstract | This study is a research on teaching practice, developed in the context of an elective course on Dynamic Geometry for prospective kindergarten and elementary school teachers taught by the first author of this paper. We aim to analyse the role of GeoGeobra in the development of geometric reasoning, particularly the way individuals geometrically structure figures. The participants are a class of six future teachers. Data was gathered from the participants’ portfolios and classroom observation while working on an exploratory task, which focuses on constructing draggable figures. The results show that this type of activity promotes spatial and geometric structuring, beginning with the perception of elements and relationships that enable the dynamic construction, and moving on to the description of the construction using formal concepts associated to the tools of the DGE. | pt_PT |
