Systems can be difficult to describe. All of us know the respiratory system exists, but few can explain its essential roles and responsibilities in sustaining living organisms. Effective learning systems are no less difficult to describe. Join this session, based on the book Becoming a Learning System, and focus on the essential attributes of a learning system, roles and responsibilities of key players, strategies for building district- and school-based learning agendas for learning teams, and how systems thrive in a cycle of continuous improvement. Hear how one district made the journey to become— from district leadership to school-based leadership teams—a model system of learning. Learn about the successes and the challenges; leave with strategies you can use to apply to an issue in your own district for which professional learning is an appropriate response.
