摘要：This short book is the latest output from Etienne Wenger-Trayner and collaborators, an engaging conversation on professional learning firmly grounded in the work and voices of practitioners and those teaching or researching with practitioners across diverse fields, disciplines, professions and contexts – education, health, social care, environment, public relations and management. Over thirty contributors contribute stories of learning in their own practice, those in the first part of the book derive from interactive workshops facilitated by the Practice Based Learning Centre for Excellence in Teaching and Learning (PBCETL) 2005- 2010, at the Open University. .
