I’ve been playing with using QR codes in the classroom, simply as a way to make things more easily accessed. All of my students this year have smartphones and it is their go-to way of accessing information. So I figure I may as well be using what they’re most comfortable with. The post below is not any amazingly awesome use of QR codes in the classroom. It’s just a simple way to share information with my students in a way that they seem to be most comfortable with.

Using QR Codes To Encourage Students to Check Their Solutions
Are you using QR codes in your classroom? I’d love to hear your ideas.

This is pretty cool, I’ve been trying with the idea of Qr codes in lessons but I’ve only really tried it with my post 16 classes. Do your students abuse the privilege of using their phones? Do all the smartphones have Qr reader capabilities?
I am monitoring them in the classroom and honestly, they’re usually so caught up in working through the problems with their “team” that it’s not a problem (they don’t want to get behind by being off-task). I am using this with all of my students, grade 9 through 12 (ages 14-18). All of my students have smartphones and can read the QR codes. I recommend RedLaser to them. Glad to hear you’ve been finding success in this also!
