The document discusses the anatomy of a 21st century educator and identifies key components or "body parts" that modern educators need. These include: being a bridge between educational research and teaching practice; participating in communities of practice to continuously improve teaching skills; and making use of learning technologies to scale instruction, unbundle education, and cope with disruptions. Examples are provided of flipped classrooms, open educational resources created by students, and a peer instruction system used in a physics course that increased student engagement and understanding.
