One of the apps I have been working with this week are QR (quick reference) scan codes. The film above shows you how to use it and some uses for it. Here are some additional uses for it in the classroom. If you want to download it to your Android device, use this link and go here for the Apple ones. In a nutshell if you do not have enough laptops for your students, you could make a QR code (it takes two seconds). Then, for example, you could use a PR code to link to a reading for the day or a quiz or even to homework. The last item is nice because not all the students like to write it down or even type it on their phones, so they would just scan it and go. You could also change the assignment without changing the QR code.
