A proposed plan outlined in this speech divides the school year into three instructional units of 12 weeks each during which time student attendance is required. Three interim units of 15 work days and five vacation days are scheduled in April, August, and December. These interim units are designed to be used by students for remedial work, enrichment, acceleration activities, or for vacation. Under this plan, teachers can choose among five basic areas of differentiated activities: (1) teaching, (2) curriculum development and evaluation, (3) consulting or training teacher, (4) inservice training, and (5) no contract obligations during the interim period.
