The P.E.R – Play, Explore, Research project of Fondazione Reggio Children-Centro Loris Malaguzzi, made possible by the collaboration with The LEGO Foundation, is a platform to bring together educators, researchers and policy makers so as to further develop the relationship between play and learning and learning through play for children globally. This series of publications aims to shed light on the contributions that characterised each individual conference-action in the five countries, starting with the presentation of the P.E.R. project in Italy, in Reggio Emilia, on 16 and 17 November 2023 at the Loris Malaguzzi International Centre, accompanied, as a national preview, by the presentation with workshop of Octostudio, a creative coding app of the Lifelong Kindergarten at the MIT Media Lab.
