Research objectives

Our research objective is to provide tools digital tools to facilitate learning fractions, one of the most difficult and dreaded concepts in primary school.

Our research hypothesis is that the advantages brought by Augmented Reality can enhance the motivation of children, their autonomy and help understand complex notions related to fractions. The project focusses mainly on one of the main pedagogical challenges: placing a fraction on a number line.

We are currently carrying out experimentations. If you wish to use the applications in your class, please contact .
