La Influencia conjunta del uso de geogebra y lápiz y papel en la adquisición de competencias del alumnado

This study is part of ongoing research on the interpretation of students’ behaviors when solving plane geometry problems by analyzing relationships among DGS (GeoGebra) use, paper-and-pencil work and geometrical thinking. Our theoretical framework is based on Rabardel’s (2001) instrumental approach to tool use. We propose an analysis of the acquisition degrees of the instrumentation and instrumentalization processes, the resolution strategies in both environments and the interactions between the different agents We seek relationships between students’ thinking and their use of techniques by exploring the influence of certain techniques on the students’ resolution strategies.
