Teachers are savvy about finding what they need for students and lessons in their classrooms. They scour websites and thrift stores and pick people's brains for ideas and resources. When it's for the success of their students, barriers crumble by the sheer power of their will and passion.
In working with schools and teachers, I've found that the most powerful change in practice comes from Follow-Up Coaching, and a focus on student learning as a priority over teacher actions.
When we "provide" teachers with information and strategies about good classroom practices, and then leave them to implement those changes, often very little actually shifts. Instead, setting student-centered goals based on new initiatives, curriculum, or strategies (What would students be doing and saying if I was successful with _____? implemented ____ ?), helps teachers make small manageable changes to improve their craft.
