That is pretty much the way I learned, start trying to get up fakie. The way I teach it now is to have them get up regular, then slow boat way down and have them surface180. Practice this just outside the regular toeside wake.
Once you are riding fakie the tendancy is to want to bend at the waist and let your arm out straight. You have to correct the body form which usually means try to stand up straight and pull the handle into your hips.
Once they can ride straight for a bit it is a quick transition to slowly edge heelside at the wake, pop, let go with your front hand and ride away regular.
