Educative and educational

As far as I know "educative" and "educational" should be synonyms, and thus interchangeable.

Thank you Marius. I didn't mean I didn't understand the word. I simply meant that I don't recall ever seeing it used.

I was wondering if this was one of those "disoriented/disortientated" situations, or one of the "brunet" situations.
