The following is a short list on why many schools are moving to a block schedule.
Some schools have as many as eight different periods a day.
If we asked adults to change desks, jobs, bosses, workplaces and topics eight different times a day they would revolt. This fragmentation leaves little time for connections to be built between topics or reflection. Little time is left in one day to teach any subject in depth or have time for practice. Impersonal, factory like environments. The push to get kids through six, seven or eight classes a day does not give students or teachers a chance to develop the relationships that foster learning.
