"A valuable contribution to the field. Good mathematics teaching begins with a thoughtful analysis of important mathematical ideas, and effective mathematics professional development begins with thoughtful analysis of mathematics teaching. These materials both acknowledge the complexity of the work and provide a carefully designed and sequenced curriculum for understanding it."
"These materials demystify important aspects of professional development leadership and provide scaffolded learning opportunities to develop and apply skills for planning, facilitating, and assessing professional development in mathematics. As a leadership curriculum, this method dispels the idea that effective leaders of professional development are born, not made."
"Provides a curriculum based in authentic learning situations to strengthen professional development. Leaders will consider and study the many complexities of developing learning communities that deepen understanding of mathematics."
"Helps develop a broad skill set to create a powerful learning experience for professional developers. Carroll and Mumme focus on the practical application of their materials and provide deep and robust content, useful tools and resources, and a strong research base."
"The most usable, unique, and rigorous professional development tools to come along for mathematics. An effective professional development tool to nurture teacher leaders."
"Mathematics leaders will find these materials unique in that they are designed specifically to help professional developers. We learn to be effective professional developers through viewing, analyzing, and reflecting on actual professional development situations and applying that perspective to our own practice."
