Back in March, I wrote about QR codes. I just came across this document which offers some interesting ideas on how to use QR codes. It was written for a K-12 audience, but there are a bunch of ideas that are relevant to higher education.
I learned a couple things I didn’t know.
First, the size of the QR code is correlated with the size of the URL. Makes sense. I just didn’t know that. If you have a long URL but want a small QR code, use a URL shortener like bit.ly or goo.gl then create your QR code. Actually, bit.ly and goo.gl make it easy to create QR codes. Use bit.ly or goo.gl to shorten the URL. Paste the URL into your browser’s address box. Then add ‘.qr’ at the end. Hit enter. Bam. QR code. Just copy and paste the code wherever you’d like. For example, this link will take you to the main page of my blog: http://goo.gl/FtvWJ. When I add .qr at the end, http://goo.gl/FtvWJ.qr, I get this QR code. I right-clicked on the image, selected copy, came here and clicked paste.
For generating QR codes from websites, I use a Firefox Addon called QRLinkMaker. I right-click anywhere on a webpage and select “QR code.” A pop-up box gives me the QR code. I right-click on the image, click copy, then paste wherever I want it. If you right-click on an image, the generated QR code will send users just to the image.
The second thing I learned is that one of the QR code generators, QR Stuff, let’s you change the color of the code. That could be useful. [If you use QR Stuff, you can just right click on the preview image to copy it.]
One suggestion offered in the document is to create a tour of campus for new students. I can envision something like this. The students get a map with certain areas marked, such as the bookstore. Outside the bookstore are 2 QR codes. One is labeled “Website” and printed in black. The students scan the QR code into their phones to visit the bookstore’s website. The other is labeled “Video” and printed in blue. The students scan the QR code to watch a short video. The video could be something like the bookstore manager welcoming students to the store and explaining some of the key things students need to know about the bookstore. Clearly there’s nothing special about the color of the codes other than, with experience, the students will see the color and know what kind of information the code with give them.
If you do this as a scavenger hunt for something like a freshmen orientation course, you can have students respond to questions. While the number of students with smartphones is on the increase, not all students have them. I suggest having students work in pairs or small groups where at least one person has such a phone.
My syllabus is available on my website as a pdf. After I post it, I generate a QR code for it, add it to my syllabus, and then resave my syllabus to my website. This is from the top left corner of my syllabus. Although next quarter, I’m going to generate a QR code from URL shortener so I can shrink the size of the QR code.
When you distribute handouts, include QR codes to online content, such as videos. It’s a whole lot easier to scan a barcode and watch a video on my smartphone than it is to type a URL into my browser.
I’m also picturing my next poster presentation at a conference. I can add QR codes that direct visitors to websites or videos. Actually QR codes can be used for anything, really. Let’s say at my poster presentation, I run out of handouts. Scan this code to generate an email to me with the email address, subject line, and message already filled in. Or better yet, if you use Dropbox, put your handout in your public Dropbox folder and create a QR code for the URL of that file. Visitors can scan the code to download the file to their smartphone.
Earlier I mentioned a scavenger hunt for a freshmen orientation course. QR codes can be generated for plain text (see QR Stuff again). You start students off with some clue, like, find the Campus Security office. When students arrive there, there’s a QR code posted next to the door. Scanning this code generates a message that directs students to a specific book in the library.
Perhaps in the front of the book is another QR code that generates a phone number. Students call the number, and it’s the office number of their instructor. That’s how the instructor knows the students have completed the hunt. Granted a 2-stage scavenger hunt isn’t very useful, or fun for that matter. But you get the idea.
QR codes make it easy to move between the real world and the virtual world. We no longer need to be in front of a desktop or laptop to access the internet. For many students, the internet is at their fingertips. Let’s use it.
