I believe the original post suggested comments about UK and other non-US schooling, but in any event it's been interesting to hear from everyone.
There's an omission I'm curious about that seems to be true of everyone, namely nothing or almost nothing about Jews and Jewish history. My impression is that, here in the United States, students arriving at university have heard a little bit about the Holocaust and the 6 million, and that's about all they know. My memories from more than 50 years ago suggest that in high school some of us saw some minutes of a film about the Holocaust that had the St. Matthew Passion as soundtrack music, and that's about all. I lived at the time in southern Oregon where there was almost no sense, for me anyway, of a Jewish presence.
I think this is a pity and a curious situation. To start with, here you have a people with more than 3,000 years of continuous history -- I italicize to emphasize that I'm not referring to material that many would assume is just myth or legend. If something has to have no "supernatural" elements, then a remarkably high percentage of the Hebrew Bible/Old Testament narratives should qualify. I've been reading about Samuel, David, Solomon &c. and am impressed by how, though to be sure there's a theme of God's providence, so much is unquestionably datable history. There's rather a lot of history too about the Assyrians, Babylonians, etc. that exists that's of interest in its own right and also relevant to learning about the Hebrew people. I should think there could be a built-in interest factor about a people who have experienced repeated deportation, the Diaspora experience, etc. that would be teachable and potentially interesting to youngsters. And of course the contribution of Jewish individuals to Western culture is manifold and profuse. Shouldn't it be a matter of common knowledge, to know some things about the Jews after the first century AD? I mean, for example, anyone should know something about the difference between Sephardim and Ashkenazi, but you didn't get that in school -- did you?
So what's the deal? Is it that Gentile (like me) curriculum designers think that a course or long unit on Jewish history would provoke student resentment or parent annoyance (What about our Swedish/Irish/French/whatever history?). But basically to ignore the Jews till one gets to Hitler is surely a big failure. It seems to me a huge gap in government-sponsored education. Can anyone shed light on this? Was your experience different from mine?
