Now I know this doesn't generalize to every single American that ever lived, but it's common enough to note:
Americans all know their gazillion presidents from memory. They can tell you all sorts of details about important historical moments in the formation of their nation. There are American flags in every single American classroom I have ever seen. And I don't know how common this one is, but the American constitution is on the wall of every single classroom I've taught in and been a student in.
Is your country like this?
I haven't been able to find the video online, but there was a CBC survey on university campuses across Canada, and the basic consensus was an utter fail of knowledge about Canada's history.
If I were to sum it up, there is no cultural expectation in Canada to care about the strengths or weaknesses of my country's history. Like that scene between Rafiki and Simba in The Lion King, there's an attitude of, "It doesn't matter! It's in the past!" There is a cultural expectation to care about the present moment and how that interacts with other countries, and that's the context that is expected.
I absolutely see the value in both of them--context is crucial. But they are different contexts, and I can't figure out which one is more common. They seem to be polar opposities.
