Portable Electronic Devices

I want to reiterate something I said in a previous e-mail: keep portable electronic devices out of sight during class time. That was a condition stated at the outset of the class, both by me in person and on the syllabus. If you can't abide by it, please officially withdraw from the class. The use of such devices during class is not only disruptive to teaching and learning, but also personally insulting to me. I do my best to treat students with concern and respect; I expect something of the same in return. If that seems too much to ask -- though, of course, it's not -- then, as I said, please offically witdraw.
