It's a great video that you could use with your class. If you skip to the 7:20 mark, you'll see some great tips for how to use the "Do Not Disturb" feature to keep you focused.
Some of the tips from students were awesome:
- Leave the device in your bag when not using it
- Don't install any non-school apps
- Turn off notifications
My favorite was from the student who was put on restriction. He said that his grades got so much better while he was restricted, that he chose to keep those restrictions on even after he earned the privilege back. Now that's self-awareness!
