This unique collection of 12 research projects carried out by experienced practitioners in the play sector in the UK and USA puts forward a range of perspectives on children's play and adults' relationships with it. Drawing on a diverse range of research methodologies, the studies consider adults' memories of play; the co-production of spaces where children can play (in adventure playgrounds, out of school clubs, children’s zoos, children's museums and public space); therapeutic approaches to playwork; playwork and wellbeing; supporting the play of severely disabled children and young people; play and contemporary art practice; and children's use of technology in a playground. Offering a fresh look beyond the dominant singular voice of developmental psychology, this book is essential reading for anyone studying or working with children at play.
