For students in any type - SEL, Rotorcraft, Glider - having a final approach "box" to hit gives clearer feedback on the approach than a slick turning arrival. At the expert level, I can accept that the continuous turn is more fun, but for low-time pilots it really helps them check their progress if they know they should be close to a specified altitude at a specified distance from the landing zone. Of course, there are adjustments for winds, but being able to instantly evaluate whether you're higher or lower than target helps you make immediate corrections. TLAR works better for experienced pilots.

I remember going up with a friend who was a newly certified Private-SEL. His approaches and landings were all over the place until I showed him how to crosscheck himself by looking for 500' at 1/2 mile on final. With that in mind, he was able to mentally project his progress better and make quicker adjustments.
