I have found that there is a time and a place for multitasking in the classroom and it is NOT when I'm going over new and complicated material. GEN Yers seem to think they can be on the internet, check their cell phones, glance at Facebook, etc and still understand the complicated information I'm going over. They "hear" it, but they're not processing and retaining the information. I really need their attention 100% when I'm going over step by step how to do something. If they miss a step, things don't work. Then I wind up explaining it all over again and students get frustrated.
