Large portions merely address technical problems of scheduling. The inherent credo in this approach is that introducing one of the seven schedules, if done properly, is the bain of school reform. Others caution that research and evaluation studies on the subject are chronically deficient. As of this writing, the jury about school scheduling is still out. Common sense dictates that it is not the schedule that makes the difference, but what you put in it.
Scheduling is neutral.
It is a picture frame that can enhance the art that is put in it. But if there is no art or only a partially finished art, the frame is wasted. It is for that reason that the literature on scheduling began with a crescendo and ended with a pianissimo. Scheduling depends on what is put in it. Among the most important features that must be faced before new scheduling is introduced are curriculum development, teacher preparation, and focus.
