Bridging the gap between technology design and school practice: a specific experiment within the ReMath Project

This contribution describes an experiment carried out by a team within the ReMath (Representing Mathematics with Digital Media) European Project (http://remath.cti.gr). Within this project six digital dynamic artefacts (DDAs) have been developed, thirteen experiments have been planned (Artigue & al., 2007) and carried out, analysis of the collected data are still in progress. In this contribution, we focus on the case of the Aplusix DDA (http://aplusix.imag.fr), from the point in which the designers deliver their product to the team in charge of planning the experiment, up to the point in which the artefact is experimented within the ReMath project
