QR stands for Quick Response code. Basically, it is kind of like a barcode. A lot of information is encoded in the small picture. To get the information you use an app to take a picture of the code, which then relays the information to your device. QR codes can link to websites, pictures, text you input and more.
So how can this help you and your students? Imagine never having to help 24 second graders type in a website's address or navigate to a link. Ahhhhhh, relief! QR codes can be used to link students to homework assignments, help guide them to good websites for research, for scavenger hunts and more. Currently, I am having my classes use QR codes to read book reviews. Having them scan the QR codes is much easier and takes less time than having them head to a review website, type in a book's title and read the review. Plus, since they are small and the devices that read them (tablets, phones, etc) are portable, I can post the reviews right near the books saving even more time.
Another great thing about QR codes is that students can create them. It is very easy and only takes a few seconds. This past week some 4th graders created QR codes for me with very little guidance. To create a QR code first go to a free generator site. I use http://qrcode.kaywa.com/ . Depending on what kind of information you want to link to, click the different options (SMS is text). Input the information, pick the size you want your QR code to be and click generate. You can then print your QR code from there, or save the code as an image file to put into your documents, on your website, etc.
To scan a QR code download a QR reader (plenty of free ones) onto your device. All of the school's iPads have a QR reader on them called "Scan". Open the app, point the iPad at the QR code and it will read the code and go to the information. Easy, peasy!
