Flexible modular scheduling is discussed as a means for achieving individualized instruction in the classroom. Scheduling, in general, is presented as a compromise among four elements: a) individualizing the educational program for each student, b) utilizing available facilities, c) utilizing available staff, and d) capitalizing on staff competencies. Variable schedules, or blocks of instruction time, are also examined as they lend themselves to instruction cycling. Flexible modular scheduling, or schedules of small blocks of time, is discussed finally in relation to both alternative and traditional forms of scheduling.
