The Development and Demonstration project has trained interns to lead Effective Use of Time inservice workshops for secondary school teachers of basic reading and mathematical skills. These interns then returned to their home bases and trained teachers who could in turn train other teachers to use the Stallings Effective Use of Time methods. The Effective Use of Time/Staff Development Model was developed during a multi-phased study in secondary schools, and its goal was to help teachers learn to manage their classroom time effectively. This final report contains four sections. Section 1 outlines phase 1 and 2 of the development model, phase 3, "Training Teachers as Trainers," and phase 4, "Training Interns as Apprentices." Section 2 discusses the Effective Use of Time Intern Training Program. Section 3 describes project implementation at the four home sites: (1) West Virgina State Department of Education; (2) University of South Carolina; (3) Northern California Juvenile Court Schools; and (4) San Fernando Valley Federal Teachers Center. Appendices include: (1) letter to sponsoring agencies; (2) summary of workshops; (3) feedback letters to interns; and (4) site report from West Virgina State Department of Education. (JMK)
