You have chosen a movie or video to show your class. You have picked something that you are pretty sure they haven’t seen and hopefully will enjoy and learn something from. You start the movie or video and then as you look across the class you see many students embraced by the warm glow of their cell phones. They are sending important messages to their friend in math like :
“what ya doing”
“math” etc, etc
Fight the Glow! I give my students the above graphic organizer sheet than can be adapted to any movie, TED talk, or YouTube video. It gets both sides of the brains going, helps them focus on key ideas, and is not time consuming to mark. Not guaranteed to eliminate all cell phone glow but it does help. Good luck!
