You see (only) what you predict: the power of geometric prediction

We consider geometric prediction (GP), as a mental process through which a figure is manipulated, and its change imagined, while certain properties are maintained in- variant. In this report on a recent study, we concentrate: 1) on capturing processes of GP before explorations are carried out in a dynamic geometry environment (DGE), to gain insight into possible characteristics of such processes; 2) on possible implications it can have in a subsequent process of dynamic exploration of a DGE figure, in par- ticular in the solver’s interpretation of feedback from the DGE.
