We are all different but there are clear cut better methods of doing things. Some of the methods may get the person flying faster but they will create a problem down the road.
Example:
You can cut lite ply with a razor blade but it is a lot better to cut it with a saw. Its a given known fact. Just as telling someone to envision them self inside the plane is not a recommended method. Picture 3 - 4 months down the road when they are coming down the field inverted and they start to play with the rudder. Now you have to imagine yourself upside down coming at yourself (in which case there is seemingly no reversal of the controls).
I also agree with the method above about just letting them figure it out for themselves for the first few times. The instructor should teach reactions to the planes attitude and then transition into making the plane react the way you tell it to. I also think that the instructor should tell the student why the plane does what it does when they move the stick a certain way.
