Recesses or breaks are necessary for students and for teachers too. It’s a chance to relax and rest your mind, just for the next class.
Another point: in my opinion classes for example 8:00 through 15:00 or similar class schedules aren’t practical.
Are you able, as a teacher, to teach all those hours or nearly, and in a continuous way? As a student, are you also able to bear with that burden?
I know sometimes, in Spain, life itself pushes you to that trend, but: are you able to reach the last hours fresh, both whether you’re a teacher or a student? / Photo from: jacksoncountyrealestateck com
