The Cape Girardeau Project was involved in planning-operational year activities during the 1971-72 academic year. The two major kinds of activities centered on those dealing with planning and pilot classes in preparation for implementing the innovative Trimester/Modular Scheduling Plan at Cape Central Senior High School; and those aimed at preparing teachers through inservice education for more effective use of extended class periods under the new scheduling plan. Project activities in preparation for entering into the Trimester/Modular Scheduling Plan consisted of scheduling pilot classes from different disciplines and for several courses in double-period blocks of time for either one semester (90 days) or one trimester (60 days); planning sessions involving administrators, teachers, guidance counselors, and computer specialists; and professional travel to observe similar innovative scheduling plans. In preparation for the more effective use of extended daily class periods, project teachers were given a 32 week program of inservice education; professional travel to observe and study new kinds of organization for instruction and teaching strategies; supporting instructional services; and planning for team teaching.
