On my commute this morning, the local radio station was discussing a recent ban on Ugg boots by a Philadelphia school district because students were hiding their cell phones in the boots then using them in class. The radio announcers were discussing how cell phones in the classroom are a bad thing, but they didn’t believe banning the boots was really going to make a difference because they figured students would just hide them somewhere else.
Since I’m a big proponent of byod and challenging the thinking of others, I phoned in to discuss what I do in my classroom. I shared how as the teacher, I have my cell phone out on my desk and I model appropriate cell phone etiquette. I then talked about how we have class discussions about being good digital citizens. From their positive responses, it seems like I made them rethink cell phone use and how teachers can approach the cell phone issue. Hopefully it made other listeners think too.
On a funny note, a member of my admin team heard my voice on the radio and enjoyed teasing me for my morning sound bite 
Awesome! Good for you, we have to take control of reality and let people know that what they automatically think is not always correct. Well done.
I encourage the use of portable web-enabled devices in my class all the time (but I wouldn’t have had the guts to call into a radio station like you did, kudos!).
In particular, in my grade 12 chemistry class, I post answers to all homework and handout questions on the course website I maintain for the students and parents. To make getting to the answers easier (instead of navigating the website), I provide QR-codes right on their handouts that point directly to the answers. My class wouldn’t be the same without those devices!
