Several years ago I gave a lecture at the University of Washington on the situation of women in ancient Rome. Afterwards, two co-eds asked me about the Roman Empire. Where and when was it, they wanted to know.
Thinking this was some sort of tease, I told them it ruled Southern California in the 1920s. I was stunned when they began to write that down.
So, after I explained about Rome, I quizzed them further, to test what they did know about history.
Not much, it turns out.
How about maybe we have a couple semesters in high school, too? It would be kinda nice if a high school graduate, after a history course on World War II, knew more than the Tuskegee Airmen, and Rosie the Riveter.
