The Global Dialogue Think Piece, by Michael Fullan and Steve Munby, was written to stimulate participants at the Global Dialogue Webinar to debate the challenges and opportunities presented by cluster-based school collaboration when used as a vehicle for school improvement. Following the Global Dialogue event that took place on February 11, 2016, Fullan and Munby updated their paper to reflect reaction and input from John Hattie, Viviane Robinson and hundreds of other school teachers and leaders.
