Book excerpt: What makes a powerful and results-driven Professional Learning Community (PLC)? The answer is collaborative work that expands the emphasis on student learning and leverages individual teacher efficacy into collective teacher efficacy. PLC+: Better Decisions and Greater Impact by Design calls for strong and effective PLCs plus—and that plus is YOU. Until now, the PLC movement has been focused almost exclusively on students and what they were or were not learning. But keeping student learning at the forefront requires that we also recognize the vital role that you play in the equation of teaching and learning. This means that PLCs must take on two additional challenges: maximizing your individual expertise, while harnessing the power of the collaborative expertise you can develop with your peers. PLC+ is grounded in four cross-cutting themes—a focus on equity of access and opportunity, high expectations for all students, a commitment to building individual self-efficacy and the collective efficacy of the professional learning community and effective team activation and facilitation to move from discussion to action. The PLC+ framework supports educators in considering five essential questions as they work together to improve student learning: Where are we going? Where are we now? How do we move learning forward? What did we learn today? Who benefited and who did not benefit? The PLC+ framework leads educators to question practices as well as outcomes. It broadens the focus on student learning to encompass educational equity and teaching efficacy, and, in doing so, it leads educators to plan and implement learning communities that maximize individual expertise while harnessing the power of collaborative efficacy.
