One of my biggest frustrations as an instructor deals mainly with the difference in what I think of as "generational rules". In the syllabus addendum for every class I teach, I specifically state that cell phones are not to be used during class time, including texting. I don't think that this is an unreasonable rule, yet every quarter I've had to reprimand at least one student, typically of the 18-25 age group, for violating this rule. While my non-traditional students tend to be shocked by this blatant disregard for the rules, the other, younger students don't see an issue at all. I had one student tell me that in high school, the teachers didn't care if they "texted" during class. I find that hard to believe, but.... I realize that there are generational social rules that change over time, but I'm not ready to allow students to sit in my classroom and "chat" with their friends via their phones. Has anyone else dealt with this issue and how was it handled?
