abstract = {Summary: This report is drawn from a teaching intervention which aims at introducing spherical geometry in a primary school. Assuming a perspective according to which learning should involve students in processes leading to the explicit formulation and elaboration of meanings, this report is meant to explore the dynamics between students' elaboration of meanings emerging from an activity with artefacts and students' explicit reflection on the use of the artefacts themselves.},
