Why aren't americans taught about the rest of the world in school?

World history and current events are a large part of our academic curriculum. But yes, I will agree that our own local, state, and national history is more of a focus because that is who we are. (for the most part) I can't speak for all districts, but my own (12 years ago) taught me a great deal about the world outside my own paradigm. It is difficult to be taught everything there is to learn in the amount of time there is to learn it. We have standarized tests to work towards!
