Yrjö Engeström is Professor of Adult Education and Director of the Center for Research on Activity, Development and Learning (CRADLE) at the University of Helsinki. He is also Professor Emeritus of Communication at the University of California, San Diego. Engeström applies and develops cultural-historical activity theory as a framework for the study of transformations and learning processes in work activities and organizations. He is widely known for his theory of expansive learning and for the interventionist methodology of developmental work research. His most recent books include From Teams to Knots: Activity-Theoretical Studies of Collaboration and Learning at Work and Learning by Expanding: An Activity-Theoretical Approach to Developmental Research.

'This is a very important book. It brings together some of the most significant papers in Engeström's archive and provides them with a new introduction and rationale. In his first chapter he also muses on the possible future of the learning sciences. This prospective view is grounded in the legacy that is so well captured and explicated in the rest of the book. It will be of great value to newcomers to the field and serves as an invaluable source of reference for those who are more familiar with the work.' Harry Daniels, University of Oxford
