In this presentation, the Swedish team engaged in the SMOOTH project would like to share some findings on educational commons in explorations of an urgent question, shared by preschool- children and adults, concerning the human being’s place in nature and the relation between nature and culture. A pedagogy of listening, pedagogical documentation and project work (Olsson 2023) – all methodologies deployed within SMOOTH – have constituted the starting point for educators, principals, researchers and artists’ building up a Playworld/Interactive performance (Lecusay & Nilsson, 2020; Kollaborativet 2023) where children’s interest in the common question could be further explored. In the presentation, aesthetical, pedagogical and philosophical (Bergson 1896/1991; Dewey 1934; Vygotsky 1978) perspectives are put to work in qualitative analysis of children as commoners, engaged in commoning practices and the creation of new commons (Pechtelidis & Kiuopkiolis 2020) in the Playworld/Interactive performance. Additionally, recent results from a quantitatively informed study of children’s prosocial behaviours in the Playworld/Interactive performance are presented, and we draw some preliminary conclusions on what kind of definition could be given to educational commons in early childhood education and care (ECEC).
