Pilot nav is probably still taught in the same fashion at EFT, but the use of the CDR is (I would assume) not necessary in the days of aircraft with computers.
In my relatively short 15 or so years in the RAF I have never seen one of these CDRs in use, nor have I been taught how to use one at groundschool (and I've been on lots of groundschools...)
MDR is the way forward, for anything more precise you can ask Google
