This book grew out of a three-year study of one child, documenting her social, emotional and cognitive development. It provides a valuable insight for all students and teachers of child development at the individual level. The observations and assessments are presented here as a model for students to use in their own observations aimed at supporting and extending children's learning. The book sets out theories and traditions in early childhood development and care, as well as ways of analyzing observations. This is an essential book for students and practitioners involved in research and observation in early years settings.
