Abstract
This study focuses on a team of three primary and lower secondary school student teachers struggling with a percentage problem. The conditions and constraints under which their inquiry unfolds and the very vicissitudes of this inquiry are analyzed in the framework of the ATD. First, a praxeological reference model is constructed through a mathematical analysis. Then the model of didactic moments is used to analyze the construction of a praxeology centered on the type of tasks for which the observed students built up a technique.
