I remember the good ol' days, when teachers could actually tell when their students were using the Internet.
With Google Glass and now this Muse spinoff, it's hard to know exactly what students are focussing on. Man, I miss the days of Minecraft and Snapchat, 24/7! ;)
Really I don't miss the good ol' days; because think of the opportunities for learning these new technologies will bring! However, in only a few year's time, I can imagine even today's most hesitant teachers (put that cellphone away!) will long for simpler times, when kids brought only iPods to class.
