A classroom activity for high-school students, aiming at introducing space geometry from plane geometry has been introduced back in 2009 by Mammana, Margarone, Micale, Pennisi and Pluchino (2009a). The activity was based on the use of a Dynamic Geometry System and of the analogy between figures. Several aspects of the activity have been studied in…

Dovigo, Fabio – European Early Childhood Education Research Journal, 2016
Argumentation has been widely explored in primary and secondary school as an important opportunity to promote learning through the development of processes that are both social and cognitive. However, less attention has been devoted to the way argumentation begins to take shape in the early years, especially during conversations which take place…

This paper addresses contributions that dynamic geometry systems (DGSs) may give in reasoning by contradiction in geometry. We present analyses of three excerpts of students' work and use the notion of pseudo object, elaborated from previous research, to show some specificities of DGS in constructing proof by contradiction. In particular, we…
