Titre : AGREGA GAME, a serious game about understanding and managing the circular economy of aggregates on a regional scale Auteurs : Jean-Marc Douguet, Fenintsoa Andriamasinoro, Philippe Lanceleur, Revue : Technology and Innovation Numéro : Issue 3 Volume : 8 Date : 2023/05/11 DOI : 10.21494/ISTE.OP.2023.0975 ISSN : 2399-8571 Résumé : The supply of natural aggregates in France has become a major issue due to the expected increase in consumption, both in the field of construction and public works, and due to the environmental and societal constraints that their exploitation generates. The ANR AGREGA project aims to develop a methodology and an operational simulation tool in order to conduct a prospective analysis of the aggregates market on a regional scale, over 30 years. However, the choices to be made have yet to be accepted. As part of this research project and as part of training programs within the University of Paris Saclay and UNILaSALLE, an innovative pedagogical approach has been proposed to develop collaborative learning. It is based on an integrated environmental assessment, which aims to mobilize a variety of tools for discovery, simulation and deliberation around the question of the supply of aggregates. It is based on a participatory approach, called INTEGRAAL, which aims to involve actors (here, the students) in dialogs relating to the decisions to be taken, individually and collectively, concerning the supply of aggregates. Pedagogical innovation also comes from the possibility of enriching the interactions between actors by using a large wall of stereoscopic images, known as an Immersive Wall for Research and Education.
