For a long time, teachers tried to manage smartphone usage in class, trying their best to make sure kids weren’t screwing around instead of learning. Now, educators have a reason to let kids stare at screens, as the Google Classroom app is now available on the Play Store. The app will let students and teachers stay on track, digitally. Homework assignments, future work deadlines, and assignment collection are all part of the app’s feature list. The app is free for anyone with a Google Apps for Education account.
