Abstract
In a recent study (Vincent, 1998), van Hiele levels were used to monitor students' progress
in geometric understanding when learning with Cabri geometry. The following report focuses
on the experiences of two of the twelve participants in the study: Student D who was initially
at van Hiele Level 0/1 and Student L who was at Level 2 for most concepts.
