Classroom in the Cloud: 10 Ways to Use QR Codes in the Classroom | QR-Code and its applications |
QR codes are 2 dimensional computer-generated codes that can be scanned and read by mobile devices or webcams. The first time a colleague showed me QR codes, I was literally giddy with excitement. I immediately recognized the potential for QR codes in my classroom.

Creating the QR code is surprisingly easy. I use - simply type in the text or url of whatever content you want the code to direct toward, and you're good to go. It's literally that easy. From there, the QR code can be downloaded, added to worksheets, emailed, etc. It can even be scanned directly from an LCD projector or computer screen!
