For many years, coauthors Rick DuFour and Bob Marzano have been co-travelers on the journey to help educators improve their schools. As Rick has focused on bringing the professional learning community process to life in schools, he has relied heavily on Bob¿s vast research on effective teaching and effective leadership. Bob has come to the conclusion that the best environment for great teaching and leading is a powerful PLC. In Leaders of Learning: How District, School, and Classroom Leaders Improve Student Achievement, the authors have combined their passions into one book to articulate how effective leaders foster continuous improvement at the district, school, and classroom levels. Rick and Bob argue that no single person has all the knowledge, skills, and talent to lead a district, improve a school, or meet all the needs of every child in his or her classroom. They assert that it will take a collaborative effort and widely dispersed leadership to meet the challenges confronting schools. Leaders of Learning focuses on district leadership, principal leadership, and team leadership, as well as addressing how individual teachers can be most effective in leading their students by learning with their colleagues how to implement the most promising pedagogy in their classrooms. The first part of the book focuses on how district and school leaders create the conditions to support the collaborative culture of a professional learning community. In the second part, the authors turn their attention to the specific work that teachers undertake as members of PLCs.
