For example lets say a student takes AP Calculus in the Fall with class over by January. Consequently adjustments are made for AP classes, also. This is not to say that I am against block scheduling. This type may look like this, half of a students classes are taken Monday and Wednesday and the other half taken on Tuesday and Thursday with all classes taken on Friday. This would allow for continuity and still allow for longer and deeper content explorations.
Block schedules offer many advantages.
Teachers benefit from increased usable instructional time due to fewer transitions and less time lost with class openings and closings. Teachers are able to plan lessons for extended periods of time and are motivated to use various instructional strategies other than lecture, such as models of teaching, learning centers, cooperative learning structures, and Socratic seminars. Fewer class changes result in a less stressful, cleaner school environment, automatically fewer tardies, and fewer disciplinary referrals. In alternate-day plans, with one or more days between classes, when discipline problems occur, both teacher and student have time to cool down. Daily record keeping also is reduced in this plan.
