The present study presents the different LVAR modes which can be constructed in Geometer’s Sketchpad v4 dynamic geometry software. The paper posits an explanation of the correlation between the five phases in the apprenticeship/learning process proposed by van Hiele and the developing theory on LVAR. A few examples of the different modes of LVAR are presented, including the answers of the student participants in the didactic experiment conducted. We can thus conclude that transformations through LVAR lead students to structure mental transformations relative to the development of their van Hiele level.
