Inside Higher Ed today features a YouTube video (below) from a Cornell instructor who becomes upset when someone yawns. Apparently, the lectures are routinely videoed by the Hotel School and the YouTube extract comes from the official recording. Although in this case the recording was official, it is well to note that cellphones can produce videos and that there are very small audio and video recorders that students may have in class. (The yawn is not heard on the video. There is a clicking sound which may be some artifact of the recording.)
Can we say this episode is a wake-up call?
