Geometric prediction: proposing a theoretical construct to analyze students’ thinking in geometrical problem-solving
Résumé
We consider geometric prediction (GP) as a mental process through which a figure is manipulated, and its change imagined, while certain properties are maintained invariant. In this paper, we explain our interest in this process and how we define it. Furthermore, we describe a tool for analyzing students’ productions. In particular, we present brief analyses of students’ interviews while they are solving a geometric open problem explicitly designed to elicit processes of GP. Finally, we summarize some preliminary results about the features of this construct. These results are part of a doctoral project aimed at gaining insight into the process of GP.
