International audienceeaching geometry to dyspraxic pupils with the use of Dynamic Geometry Software: study of conditions conductive to learning Abstract Teaching situations of plane geometry to fifth and sixth-grade students are based on different types of task, which require actions with instruments in order to produce geometric concepts. Learning geometry may hence appear to be inaccessible to dyspraxic pupils because their motor manipulation and organizational difficulties lead them to fail in the implementation of their actions. In this paper, we present an analysis framework elaborated to study the process of accessing geometrical concepts through construction with instruments with the use of Dynamic Geometry Software.
