I am sure you have heard the old joke, “What is black and white and red/read all over?” Answer: a newspaper!
Well, the same joke/riddle can apply to QR codes as well. A QR code is a bar code as shown in the black and white bar code to the right. It is considered a two-dimensional bar code because the data is read horizontally and vertically compared to just horizontally like a regular bar code. When you go the grocery store, each item is scanned using the bar code on the item and the item info and price is stored in the lines of the bar code. Similar with QR codes.
QR Codes can come in all colors now including logos and images within the QR code itself like the one to the left. To read a QR code, a QR code reader, like I-nigma or QR Droid is needed on a smartphone. The reader decodes the information contained in the QR code and processes what the QR code requests. The two codes in this post will take you to a website but you can direct a QR code to link to many different things on the internet.
I presented on QR codes at TCEA in Austin on Wednesday, February 8th to an intimate, small crowd. Considering I was presenting directly across from Hall Davidson from @DiscoveryEd and it was 5:00pm after a long day full of tons of other sessions and workshops, I was pleased to have the 20 or so people stay to view my presentation. The resources I shared can be found on the Google doc after scanning the QR code to the right.
QR codes are a great technology to use to engage students, motivate and excite them about learning using a tool to interact with academic content. Join us Saturday and if you are already using QR codes in the classroom or library with students please also come and share your experiences. Even if students are not able to use cell phones in the classroom there are ways that you can set up QR scanning stations using desktop software and I will be sharing information about that on Classroom 2.0 LIVE.
If you were unable to attend at TCEA, I will be presenting on innovative ways to use QR codes in the classroom this Saturday, February 18th at 11am CST at http://live.classroom20.com. I hope that the resources and ideas shared will be new to you as I have scoured the internet far and wide to research strategies, best practices and unique ways to use QR codes that go beyond merely scanning a code for the sake of using a new technology tool without a meaningful, relevant academic purpose. In the meantime stay tuned to my blog as I continue to write posts about using technology tools in the classroom!
