The intervention selected by the Greek team is entitled “Pedagogical utilization of linguistic and cultural diversity at kindergarten”. It targets children attending centre-based (public Greek) early childhood education settings. It focuses on curriculum, pedagogy and the school climate. It was considered a suitable and appropriate case for the needs of the current project, as it is consistent with the positive elements and strengths-based approach of ISOTIS. This selected intervention was used as a repository of activities for the purposes of a case study, since it aimed at multiculturalism/multilingualism and utilization of linguistic and cultural diversity in the kindergarten in a very innovative manner within the Greek school context. The case study aimed at conducting the intervention, based on the ISOTIS inventory, contributing to the school curriculum, the empowerment of (immigrant background) families, professional development and inter-agency coordination. The main aim of the case study was the support of the children’s home languages and cultures through home-based and classroom-based activities and through the professionalization of teachers using ICT-environments.
