Apparently students are drained by 75 minute classes as well. One of the comments on my evaluations was I should allow a 2-5 minute break for students to play solitaire!!
I'd almost suspect that was sarcasm. More so if some of my students complained about others playing solitaire.
I sometimes teach in a computer lab, where each student sits at a computer. In one location, every single computer was situated so that the corresponding student faced the wall, either the back wall of the classroom or one of the side walls. Meanwhile, of course, my computer was projecting images to the front of the room. So, the students all had their backs to me (and the projected image), and I had my back to all of them. When I complained and demanded that the room be reconfigured, the first response I received was, "Well, this way you can see who's working and who's playing solitaire--or downloading porn."
I did finally get the tables and computers moved. It's still not what I wanted (everyone facing the front of the room), but it's a thousand percent better than it was.
