This publication focuses on block scheduling. Alternative scheduling models--usually called "block scheduling" because they involve blocks of time for student learning--restructure the school day. Schools may adopt block scheduling to create more productive and personal relationships among teachers and students, to design challenging curricula that helps students to learn concepts in depth, or to develop a more intimate and student-centered learning atmosphere. This publication describes several different alternative scheduling models and how they are implemented in three New York City schools. Appended are: (1) Some High Schools with Block Scheduling You Can Contact for More Information; (2) Additional Resources; and (3) Guide to School Visits.
