This book is the result of this long collaboration. Its results give rise to rescripted promises of action research; it also introduces the concept of generative leadership that holds new descriptions about the long-term influences of participating in action research. The findings from our international study (reported initially in Edwards-Groves & Rönnerman 2013, and in Rönnerman & Edwards-Groves, 2012, and described more fully in the pages of this book) revealed the generation of teacher leading practices through action research. These findings about the development of the leader-self form the basis for this book. Our data illustrates that this is an organic process that we describe as “generative leadership”. It is a finding which adds a new dimension to the descriptions about the influences and accomplishments of ac-tion research as long-term professional learning.
