A number of people have asked me recently about QR (Quick Response) codes. QR codes are those square, blocky looking barcodes that are seemingly everywhere these days. They can be read by mobile phones and tablets and can store website URLs, wifi network credentials, email addresses, calendar event information, preset text messages, and more.
They have many applications in education. You can have students scan a QR code using an iPad to visit a website instead of asking them to type in the URL. When giving an assignment, you can link to examples of quality student work. During Open House, you can use QR codes to identify the student creator of a “Who Am I” project? Add QR codes to book covers that link to student audio or video reviews of the book. Make scavenger hunts for your students or, even better, have them make scavenger hunts for each other or other classrooms. Create a QR code that brings up a text message for parents/students to use when subscribing to services like Remind (Thanks, David Bayne, for that idea). You are limited only by your imagination.
QR codes are easy to make. You can create them for free on many different websites. Whichever generator you choose, you will need to download and save or copy your QR code in order to use it. The QR codes below link back to this website and were generated by some of my favorite sites. I think it is interesting that they all look different, yet link to the same place.
Goo.gl Google’s short URL creator also gives you QR codes that link to websites. Simply visit goo.gl, paste in the link to the webpage and click Shorten URL. The shortened URL appears on the right of your screen. Click the Details link underneath and you will see your QR code. If you use Chrome, you can install ShortenMe or another extension to generate a QR code through goo.gl for any webpage without leaving that webpage.
Pros: Google Analytics, Chrome extensions
Cons: Can only be used with webpages
QRstuff.com This site is very easy to use and allows you to create codes for a huge variety of uses. Just select the type of content the QR will link to, then fill in the blanks, set your color (yes, you can make colored QR codes!), and preview your code. When you are satisfied with the color, download the code by clicking the download button. The site is a little more cluttered than the others mentioned here, but it is still easy to use.
Pros: Colored QR codes, ease of use, one click download
Cons: Students may choose colors that do not provide enough contrast and the resulting QR code will not work
QR Code Generator: This site provides a limited number of options for the contents of the QR code (text, URL, contact, phone number, or SMS), but it offers several choices for the resulting image. You can set the size you want, and you also have option of copying embed code or a direct link to the image instead of downloading and saving if you prefer. Students like seeing the code change as each character of the input is typed.
Pros: Ease of use, choice of output
Cons: Limited input sources
GoQR.me: This is another site that allows you to make colored QR codes and see the barcode change as you enter information. The layout of the page is very clean and straightforward, so it simple to use. It works with a wide variety of input types and the generated code can be downloaded in a number of formats, or you can copy and paste the direct link or embed code for the image.
Pro: Colored QR codes, ease of use, adjustable size
Con: Possibility of QR codes not working due to low contrast color choice
Thank you to Lisa Nowakowski for recommending GoQR.me.
If you have a great way of using QR codes with students, please share in the comments.
