QR codes make it easy to quickly share important information with students. Through a QR code you can share links to websites and Google Documents (provided you have set sharing permissions to “anyone with the link”) for your students to open on their tablets or phones. You can share links to Google Calendars or to specific calendar events that students then sync to the calendars on their mobile devices. In the video embedded below I demonstrate two ways to quickly create QR codes.
The two tools featured in the video are QR Droid and Goo.gl.
