Look at the first verb you used: "am". This is from the verb "to be". For the "tag" you need to use the "be" verb again: I am a very slow learner, aren't I?
If the first verb was "have" you would use the tag "haven't". For example: You have been to Spain, haven't you?
If the first verb was "do" you would use the tag "don't". For example: You do drink beer, don't you? Sometimes we leave out the "do". For example: You drink beer, don't you?
No, I'm not sure what the "isn't" referred to now. There must have been a deleted thread there. Sorry to confuse you DG. I'll delete it to avoid further confusion.
