For this fourth book in our series of professional learning, we have asked "Guest Chefs" from around the world to add their favorite professional learning recipes. This book introduces twelve recipes that are a different approach to professional learning. They represent what our team and the guest chefs have learned over more than a hundred years of combined experience in education.While this book is not a complete guide, it does explain the value of each recipe, and it will help you understand what it takes to implement innovative professional learning. Throughout the book, you’ll find links to resources, ways to contact to our team, and even an interactive event generator.
