Did you ever see the movie Idiocracy? If not, don't bother. I can tell you the interesting part here, and the rest is pretty damn stupid. It's the premise that each generation is getting a little bit more stupid, and if you took a dumb guy from the present and sent him 200 years into the future, he'd be a genius. Every day I've gone to work recently, I've thought about this movie. I am constantly amazed at the words my students simply don't know. It's not that they just won't answer questions ... they guess, and get it wrong. Their level of vocabulary is stunningly limited. I've modified my teaching technique to include segments that I thought would only ever belong in the ESL classroom to check that the students actually know the words in front of them. I've been reading some classic sci-fi novels from the 1940s, 1950s, and 1960s. Without exception, they're clearly written for the adolescent male. (Maybe that says something about me, that I still enjoy them?) I compare the words used in these novels with the words my students know, and I can't help feeling shocked. The other thing that brings it home is that I usually have one or two older students who have retired and returned to college. I can almost always rely on them to know the words. How can you do anything if you don't have a command of your native tongue? Yet somehow or other these students have been allowed to get through high school without even learning the meanings of slightly higher level words.
