I found these to be very frustrating. Not having a phone that can make use of these really added to that. Still, I finally learned what they are and mostly how they work.

As opposed to computers with internet, most of my students have cell phones. I don’t think I’d make this a mandatory class assignment, but I would probably leave some QR codes around the room as a review, or a link to a movie clip that would enrich a lesson. I might also put a new one on my classroom door each week for the same purpose.
