In a thriving education system, students experience learning that prepares them as the vital keepers of a just and democratic society. Teachers as professionals and experts, not cogs in a machine, are essential to this goal. Sparks Into Fire offers design principles for facilitating effective professional learning in which teachers are active learners engaging in experiential learning, discussing problems, analyzing student work, and sharing their expertise with one another. The author introduces each principle with a compelling and illuminating story from his extensive experience teaching students and facilitating teacher learning in Providence, RI; Oakland, CA; and South Korea. These narratives, along with specific practices, show the reader not just what to do but how to do it. Whether you are a school leader, lead teacher, PD facilitator, or teacher educator, you can apply the ideas in this book to design collaborative experiences that revitalize teacher practice and, in turn, spark a fire in the hearts and minds of students. Book Features: Provides key principles and practices that can transform the quality of teacher learning in any subject area and across disciplines. Offers a human-centered approach to teacher learning with a focus on equity. Shares practical tools for facilitating teacher learning coupled with real-life examples and stories.
