I have done the "if the phone rings" thing (usually I have them bring cookies) but that doesn't bother me that much. In fact, the ringing rarely happens. It's the students that have their phones in their pockets on vibrate and are taking them out every 10 minutes to check who is calling them and, frequently, texting them back...Does this generation really not see an issue with this? I'm thinking about starting to do the same thing just to see what they think. Like stopping and taking my phone out during a lecture or class activity, pretend to read a text and then text back...I wonder what the reaction would be.
