Donbelid, I've never used the book- which are you using? I loked at the wdebsite (http://www.cambridge.org/elt/interchange/), but I'm unfamialiar with the book.
This is where you should check:
Well, here is the chronology of popular books on General English in Iran:
1) mid1950s - 1970s = Direct Method (this is the name of a series of books, not the method itself)
2) 1980s = chaos!!
3) Early 1990s = Headway
4) Late 1990s = New Streamline
5) 2000 - today = New Interchange (by Jack. C. Richards)
New streamline is abandoned by Iranian English institutes, but Headway is still being taught.
