The Rotation Workshop Model (RWM) is a new way of conducting Sunday School. In traditional Sunday School one teacher leads the same class of students in a new lesson week after week. In RWM one teacher teaches the same lesson for 4 to 5 weeks to a different group of students. The students rotate to a different teacher and a different teaching method every week.
For a more complete picture of the method Workshop Wonders is great resource. There are also multiple volumes of resources to help in conducting this new way of Sunday School.
