"Action Research: Principles and Practice clearly, and passionately, addresses the questions ‘how?’ and ‘why?’ adopt an action research approach to ones practice. McNiff demonstrates throughout the book that she lives the values that she is espousing. The way she brings together her passion for creating positive change through action research with the need for rigour in the way the research is carried out reminds us that she is, at the same time, advocate, campaigner, educator and academic."- Mark Robson, York St John University
