It's time to remove laptops from classrooms. 24 experiments: Students learn more and get better grades after taking notes by hand than typing. It's not just because they're less distracted—writing enables deeper processing and more images. The pen is mightier than the keyboard.

Another terrible day in the hellscape of San Francisco. Watch out everyone!

Phone bans in schools motivate kids to read. When a Kentucky district eliminated phones, students checked out 2.3x as many books from the library. At one school, twice as many students borrowed books in the first month as all of last year. Without smartphones, kids get smarter.
