I don't think I'm misunderstanding her. When we turn from base to final she says "now look at the far end of the runway" all the way to the roundout. She wants me to use the end of the runway as my guide. I think this explains why I don't pitch down enough on final and start erroring on the side of being high at the threshold. I prefer my aiming point the old way.
If this is accurate, the ask her how this technique of hers will work on a 15,000' runway or a dry lake bed with no markings further downfield whatsoever. How about a runway with a slope or a hump or convex shape? Those all exist in the real world.
I've already been warned by one of my mentors that sometimes instructors learn things they thought they knew were wrong, when a student starts asking questions. You never really know something until you have to teach it.
I'm fully expecting to have my butt handed to me by a student sooner or later, once I have my CFI. Probably more than once.
So... Ask some pointed questions. The above ones are a good "aiming" point for those. Heh. Maybe you'll be "that student" that gets her to talk to another instructor about the technique and realize she missed something in it along the way.
I can't see how teaching someone to be consistent about a glide path angle works geometrically, if you're having them look at the far end of something that can vary in length, when trying to build a common sight picture that they should see every time, even if the runway is three miles long. The angle changes with each new runway if you're looking at the far end from pattern altitude on down.
Again if not a misunderstanding, it almost sounds like someone admonished her to use the "spot-then-transition" method and explained it poorly and she assumed it was meant to be "always transitioned" and it stuck with her, but she's somehow compensating for it, either via VSI or other glide path indications (even just a solid airspeed in a particular configuration, will yield a perfect glide path with no or little head or tailwind) and it "makes sense" to her.
Ask her how she'd shoot the visual approach and get a consistent glide path with a jacket thrown over the entire instrument panel. Eyeballs outside.
I had an instructor who was exasperated with me and my "you played with too many flight sims as a kid, look outside, listen to the engine note for RPM, and forget about the instrument panel completely" habits, who ultimately did exactly that. Jacket went over the panel and I couldn't lean on the instruments as a crutch for visual flying. (Or course later, in the Instrument ticket the complete opposite is true. Haha!)
It also happens quite a bit in sailplanes when you're sharing a thermal with more than one other aircraft -- you don't have time to be peeking inside at the airspeed indicator... Just listen and watch out the canopy to change pitch. (Of course that leads to the popularity of audible VSI indicators in soaring, but one can fly a glider without one.)
