QR-codes

Everybody knows these weird little squares, but surprisingly few people seem te knowwhat to do with them. I use them quite regularly in my classroom and find them pretty useful. 

WHAT ARE QR-CODES?

QR-codes can be created by using free QR-code generators, like this one: https://snap.vu/. Whenever you want students to visit a certain URL with their phones and get there quickly, you can put the QR-code on their  page, print it and put it on your blakboard or just project it. On your phone, it just takes a free QR-code reader that you can download in your local app store. You scan the code in the app and it automatically takes you to the right website.

QR-CODES IN THE CLASSROOM

Whenever I want students to fill out a short assessment or evaluation, for example in Google Forms, I create a qr-code so that they don’t have to type the entire URL. The first time you do this, it takes a little while, because students still have to figure out how to do this or download the right app. But after a while this really is the easiest and fastest way to use websites on smart phones in your class. And students definitely prefer downloading an app to typing an entire URL…

PROS AND CONS

I can’t really see any reason why not to use these codes, and there are a lot of options and possibilities. For example you can create one code and every lesson make it refer to another site, or a code that goes to a different site whenever it’s rotated. You can use them to divide students into groups, or to have parents fill out a questionnaire while waiting at a parent-teacher conference. 

The only downside being, like I said, that some people don’t know how they work and that some students don’t have any space left on their phones to download even the tiniest app…
