How to deal with the mobile phone/iPod classroom PLAGUE? Rack for multiple mobiles?

I teach in a college, so our setting is very different from yours. But I handle the problem of cell phones this way: If a cell phone rings during class time, it is the signal for a pop quiz. Everything stops, everyone gets out paper, and the quiz gets written on the board. (The quiz is always related to work the students are supposed to be doing, so there is nothing arbitrary involved.) This process usually has to happen a couple of times at the beginning of the term, but when the students realize that I am serious about cell phone transgressions, they become fanatical about turning the phones off. I have also heard of professors who incorporate the technology into their lessons. They write a question on the board and ask students to text them the answer. (This is along the lines of "If you can't beat 'em, join 'em.") The truth is that as more and more students get wired in to electronic media, we as faculty are going to have to adjust. One way is to keep students so busy that cell phone and iPod use isn't practical. If they're occupied with exercises, quizzes, and projects, they don't have time to sit and play with electronics. Another approach I have encountered is the "Don't worry about it" philosophy. (This is acceptable in a college, but not where you are, unfortunately.) In this strategy, the instructor ignores the behavior, figuring that the student will get his comeuppance at test time, which usually turns out to be the case. And in a college, the student can be dropped from the class. But you don't have that luxury. I wish the world did not cast teachers in the role of police officers, running around trying to control other people's behavior. That's not what we signed on for, and not what we need to be doing. But as long as teenagers have existed, they have always been self-centered little jerks, since that is their nature. It is part of the process of maturing to become aware of appropriate time and place and the effects which one's actions have on others. If you are unable to find an easy way to solve the problem, please at least learn to feel respected and appreciated for your contribution to helping the students get more in touch with reality. Society is better off for it.
