The document discusses professional learning communities (PLCs) and strategies for creating online PLCs. It defines PLCs as teacher-led groups that focus on improving practice and student learning. It notes that many PLC implementations fail to follow the original design of being voluntary and teacher-driven. The document recommends that online PLCs be compelling for teachers, have a focused short-term goal, emphasize collaboration over cooperation, and utilize tools like wikis, blogs, and social networks to facilitate collaboration.
