First off, before we talk about those, let's go over a basic idea: URL shorteners. Have you ever had a website like this
to this link
Now, I explained that to get to this point: I like TinyURL. I've used them for a long time, and I still distributed TinyURL'd links to students and friends. However, is.gd is my new go-to favorite because it will, in addition to providing you a shortened link, generate a QR code just like that.
If you scan that in, it will easily take you to the website embedded in it.
Now, you might be asking yourself "Ok, so there are these codes all over TAPA and Webb's blog... but how do I use them?" Great question. If you have a mobile computer with a camera (like an Android device, iPhone, and iPod Touch, or an iPad 2), you can grab a QR reader app for free that will easily decode that information. I wrote about 2 that I've strongly encouraged my students to get in a recent post—Scan and Qrafter. Once you download either of these (or any other QR reading) apps, you simply open it up and hold the camera over the code, and it should automatically take you to the link. Just like that.
What are cool about these is that there are so many ways to use them:
- Print QR codes with directions or facts onto a piece of paper and tape them around a classroom.
- Project a QR of a Google map you want the students to look at onto a screen with a projector or onto a TV.
- Add them into homework assignments for students as hints or tips on how to do certain questions.
- Stick a QR code onto your business card—when you hand it to someone with a QR reader, they can simply scan in your card's code and your contact information will automatically be added into their Contacts!
- Put a YouTube video you want someone to watch on your iPad screen and have others scan your iPad. (Yes, you can scan a QR code off one iPad with another one. Just make sure there's no glare!)
Last thing: is.gd is not the only way to make a QR. Simply Google QR generator or use a website like QRstuff.com to put any link or piece of information into a QR code. And please, let me know any other ways to use QRs so I can share them with others! Good luck!
*There are hundred and thousands of URL shorteners, by the way—I just mention these two because I've used them the most. Feel free to explore other options like bit.ly, goo.gl, or many others.
