Mills Teacher Scholars is excited to share the mindsets and practices that have emerged from our last decade of learning alongside our school partners. We developed this playbook as a guide to valuing, supporting, and leveraging the knowledge-building of those working closest to students and their families. At every level of the educational system, we are asking, "What is your goal? What are you learning? What is it that you need in order to learn?" Instead of hierarchical command and control, this is a partnership stance. The purpose of this playbook is two-fold: (1) To prompt you to question the degree to which your adult learning spaces reflect the complexity of the work of teaching: Are your professional learning communities going beyond planning and progress monitoring to promoting adult learning? (2) To provide you with concrete practices you can try in order to develop an adult learning culture that leads to lasting improvements in opportunities for your students. We hope it helps you bolster your adult learning culture in service of improved learning for each and every student.
