Schools, especially the secondary schools and universities, should be encouraged to have highly visible, luminous signs near the entrances of each classroom informing passersby that the class is currently in session and to be quiet.

Another sign should be placed just outside each classroom door detailing the schedule of classes meeting in that room throughout that term.

Clocks should also be placed outside each classroom or at least in hallways and easily visible from each classroom door so that students would always know the time, especially as they are about to enter the classroom. Clocks should also be place inside classrooms so that they are visible as students enter the class, as well as when they are seated.
