"Within learning communities, members exchange feedback about their practice with one another, visit each other's classrooms or work settings, and share resources. Learning community members strive to refine their collaboration, communication, and relationship skills to work within and across both internal and external systems to support student learning. They develop norms of collaboration and relational trust and employ processes and structures that unleash expertise and strengthen capacity to analyze, plan, implement, support, and evaluate their practice."
And, haven't read this yet, but it's all over this topic: http://www.learningforward.org/news/issueDetails.cfm?issueID=357"To avoid fragmentation among learning communities and to strengthen their contribution to school and system goals, public officials and school system leaders create policies that establish formal accountability for results along with the support needed to achieve results. To be effective, these policies and supports align with an explicit vision and goals for successful learning communities. Learning communities align their goals with those of the school and school system, engage in continuous professional learning, and hold all members collectively accountable for results.The professional learning that occurs within learning communities both supports and is supported by policy and governance, curriculum and instruction, human resources, and other functions within a school system."
