QR is short for Quick Response. These pixellated bar codes are everywhere these days from grocery stores to concerts. Using your smartphone to scan things at stores, tells you where you can buy it, and compares prices easily. However, take that a few steps further and imagine using that same idea in your classroom. All of a sudden kids are all over the room scanning QR codes you generated and accessing images, videos, Google Docs, and websites you’ve recommended and linked to them. I know many teachers even use these codes in their classroom to check out SSR books, keep a bathroom log, or take roll. Interested in getting started? Use the tutorial below and then leave a comment on how you used the QR codes in your classroom.
