Discusses the training and preparation for the transition to block scheduling. Provides a summary of some of the aspects of the four-by-four block schedule and describes strategies employed to modify instruction and curriculum. Includes two sample interdisciplinary activities. (DDR)

Describes how to approach block scheduling of science classes. Discusses the planning process, specific activities that work well in longer science classes, and techniques for motivating students. (DDR)

Discusses the changes in science instruction resulting from one school's move to block scheduling. Longer class periods were found to increase the amount of concepts taught and time for activities. Figures contain a sample student schedule, goals for restructuring, rationale for block scheduling, and a sample density experiment. (LZ)

Presents a lesson plan for a block period that involves students in learning how organisms can be classified. (DDR)

This article describes some typical 90-minute lessons in biology and chemistry designed for use with block scheduling. The lessons illustrate the benefits of block scheduling to science instruction. Contains an example of one day's block scheduling of science and mathematics courses. (LZ)

Discusses the advantages of an extended school year and block scheduling for science learning. (DDR)

Examines the benefits of flexible scheduling and the initial steps used in exploring this approach. Discusses the problem of loss of instructional time and the use of an independent research period as a solution. Presents results from an external assessment, ACT score data, and CTBS scores. (DDR)
