You are correct. I have a friend who teaches 8th grade, and she says the only thing most of these kids can memorize are lines from Bachelor Part 2 or the latest vulgar rap song.
These kids are inundated with cultural trash on a daily basis. A shame that schools would waste a golden opportunity to expose kids to that which is true and good.
If you can memorize a vulgar rap song, then you have the ability to memorize Rudyard Kipling's "Recessional" or Percy Shelley's "Ozymandias".
