Book excerpt: This book uses the concept of exploration as a way of understanding transitions in children between the ages of 5 to 18 years old. Written by an international group of scholars from Australia, Brazil, China, Denmark, Finland, Greenland, India, Norway and the UK, the chapters offer a diverse set of case studies. The topics and themes covered include transitions in outdoor playtime, the transition to daycare, compassion in kindergarten, learning with fathers, transitions of Chinese traditional culture and disability. The chapters are organised into two parts, the first part covering macro transitions and the second covering micro-genetic transitions. The contributors show how both macro and micro-genetic transitions influence children's everyday lives, and how these different transitions open up new possibilities for play, learning and development. The contributors draw on Vygotsky's cultural historical theory and the understanding that children's cultural formation takes form in a dialectic relation between children's interests and motives and the institutional settings they participate in.
