“The idea of professional learning communities and learning teams offers great promise. Research and best practice have shown when teachers work collectively, focus their learning on their students’ learning needs, and assess the impact of that learning, their students benefit. In his book, Chad Dumas makes the important point that building principals have a key role to play in creating the conditions needed for learning teams to thrive. Dumas also reminds us that it’s not charisma but a principal’s understanding of the key tenets of adult learning and cycles of continuous improvement that matter most. This practical guide will help school leaders and their leadership teams as they support the growth and development of their teachers and educator learning teams. Dr. Dumas, thank you for bringing this great resource to the field!”
