First Decade of GeoGebra: Looking back through Socio-Cognitive Lenses

In this chapter we situate and investigate the place of GeoGebra among the contemporary educational software systems in mathematics such as dynamic learning systems (DLS) and computer algebra systems (CAS). In addition, we explore the cohesive role of GeoGebra in setting up a virtual community of practice. By so doing, we simultaneously consider the social and cognitive roles of GeoGebra in the first decade since it has been launched. After addressing theory and practice of GeoGebra use in mathematics education, we discuss current trends in increasing teaching and learning potential of GeoGebra and suggest promising paths for research and development.
