At our school, all syllabi specify no cell phone use during class. Now, as we are a culinary school-this makes sense. Even though I don't teach in a culinary lab, but in an academic class I follow the policy carefully. I tell students I expect (and enforce) them NOT to be on their cell phones (no texting, game playing, etc). They can use them during the break, etc. Yes, they like to be connected. I would like to wear my pajamas to school....but being an adult requires you to adjust. I get this generation is "connected" through their technology, but as teachers we need to impose expectations on students so they learn to become professional.
