One of the challenges facing a college professor is that of keeping students engaged during class lectures, especially large classes. In smaller classes, even lecture classes, professors can make eye contact, gauge reaction, and hold students accountable for their behavior. In a larger class, one wrestles with what to do with laptops that are not being used for note-taking or research; the occasional student newspaper (this problem has declined, in least in format, since the rise of the online paper); the mad texter working away at their smartphone; and so on.
But there are other forms of distraction, apparently.
Oh my. Oh, Canada.
