QR (Quick Response) codes can make classrooms more efficient and interactive. Instead of typing in a web address, a student can open an app and point his or her device’s camera at the code and walk away with a website, audio, or video open in his or her web browser. QR codes store information in an image made up of tiny squares, and anyone can create them.
It’s been a couple years since I blogged about QR codes so it’s time for some updated information.
