Allowing flexible schedules including block schedules would benefit students and teachers. Longer periods can allow time for students to explore a concept more deeply. Less time is lost during the school day when transitioning between subjects and activities. Additionally, if the time is long enough, block scheduling allows for in-depth study and peer collaboration on projects. The Education Alliance at Brown University, a educational laboratory, found that advantages with block schedules resulted in reduced discipline problems, increased achievement levels, and stronger personal relationships between teachers and students.
