Digital Smarts - Red Light, Green Light

In one Arizona district, high schools have implemented a "traffic light" system to help with managing digital device use in the classrooms. Posters in individual classrooms display red, yellow or green signals indicating if students can, or cannot, use their digital devices during class. Students say it lets them know what to expect when coming into a class and gives them a break to concentrate on the tasks at hand. They also say it helps keep them from getting their phone confiscated.
