Preschools are increasingly focused on children’s cognitive development and school preparation at the expense of supporting the development of children as whole persons. Two preschool pedagogies that fall outside of this trend, and which have roots in Vygotsky’s theories of learning and development, are playworlds and the Reggio Emiliainspired pedagogy of listening. In playworlds, children’s pretend play is based in an understanding of children as creative. The pedagogy of listening does not focus on play but understands children as engaged, reflective culture creators, and focuses on the creation of environments that afford children’s exploration, a concept not theorized to the same degree as pretend play. In this paper we investigate the concept of exploration and exploratory play in relation to pretend play, and present our understanding of a preschool pedagogy that focuses simultaneously on play and exploration as sufficient for the growth of the whole person, that is, their becoming as a subject. We make this case by presenting two projects, drawn from an ethnography of three Swedish Preschools, in which children’s play and exploration were both foci. We argue that these examples force us to rethink what children do in pretend play and in exploration, and how both pretend play and exploration are related to learning and growth. Emphasizing subjectivity the introduction of scientific concepts, and school-based learning should be reconsidered from a didactical perspective: What, when, and how will scientific concepts be useful in the life of the child and for the growth of subjectivity?
