This paper presents a model of a successful student scheduling pattern for a 45-15 year-round middle school (grades 6-8). The model allows for scheduling 100 percent of resource lab teaching time for all the student population in attendance at any one time, and formulates a house design and team teaching structure that facilitates smooth ingress and egress of each group using a revolving pattern resource schedule for an entire school year. The model suggests, for successful scheduling, that actuators identify and define relevant components of local school operation; determine by subject the amount of time to be allotted weekly; determine amount of planning time desired to facilitate a successful instructional system; facilitate flexible scheduling; slot students into the pattern required to satisfy items; and chart an entire school year in advance to discover patterns and methods of rotation that would allow maximum implementation of the school concept and the instructional system. Numerous charts and diagrams are included. (Author/DN)
