Block scheduling encourages increased comprehensive immersion into subject matter, improved teacher-student relationships, and decreased disciplinary problems. While block scheduling may offer many advantages, moving to a block schedule from conventional scheduling can be a major adjustment for both students and teachers. This guide is intended to ease the problems of change by combining a theoretical background with specific practical and proven tips and tools for implementing a block schedule. It discusses block scheduling in elementary, middle, and high schools, and includes an indepth case study of an exemplary elementary-school curriculum. It explains in detail the three block models-the 4x4 block schedule, the A/B block schedule, and the modified block-and how to select the best model. It offers guidance on curriculum alignment, pacing, and assessment models. It outlines effective instructional strategies for block scheduling, including classroom management and student-centered strategies. And it provides sample models, lessons, activities, forms, evaluations, and surveys for easy implementation. Most of the guide's 18 chapters include history and research, promises and pitfalls, and summary sections. (Contains an index and 215 references.) (WFA)
