AV8 C,
From your description I'd take the student to the training area, as low as was safe, so that they can see movement of aircraft about its axis agains external features.
Teach effects of controls (probably again) with the emphasis on the visible movement about the acircraft axis against the horizon. This is so the student can see the movement rather than to think to themself (I want the nose to go left so I must push on the left rudder pedal etc).
Then when landing the emphasis must be on "making the picture" correct rather than thinking about what control to push.
For example, when learning to yaw straight during xwind landing practice, students should be told to yaw left (or right as the case may be). This tells them what to do more directly, with a pictoral reference from their mind, rather than saying "use the rudder"
Hope this helps.
