Q:

What's the English version of the German "oder?"

In German, you often add the question word oder after a statement (", oder?") to ask whether the statement's correct. What is the equivalent of oder in English?
I always begin sentences with this scheme and then don't know how to finish them. Must I change my question structure for such questions?
I know that you can ask whether a statement's correct by asking a negative like this:

You were in school last week, weren't you?  

With this, you also have to restructure your sentence in most cases
How about this?:

You were in school last week, right?   

Is this structure used often or is this just a bad solution to the problem?

A:

Google Translate says that "Du bist ein Seemann, oder?" means "You're a sailor, right?"
Therefore, I'd say that that oder means right/correct in this context. This translation is idiomatic English.
"You're a sailor, aren't you?" = "Du bist ein Seemann, nicht wahr?", according to Google Translate. That seems to accord with what I learned in German.
What do you think?
