Open-access Using a historical diagram as a source for learning geometry

Abstract

The objective of this study is to investigate how one progresses from visualization to argumentation, from a learning trajectory that has been designed using a historical diagram as a source of learning geometry. The sequence of the learning tasks corresponds to the transformation process of the different figures in the diagram. The hypothetical learning trajectory is experienced with a group of high school students and confronted with the actual learning trajectory. The move from visualization to argumentation occurs in the graded sequence of tasks involving different types of learning activities. This graduation stimulates a change in the students' productions that is clear evidence of their progress towards what we consider argumentative competence.
