Camp Freddie: There is another problem being revealed here.
In level flight, the student is generally taught to maintain attitude by referring to where the horizon crosses the canopy bow (in R22). They learn to keep the horizon in one spot, just near the compass. In reality, they should be using a spot on the windshield directly ahead of their eyes, but with a clean windshield, there is no reference point. (Try a blob of Blutack, specially in a 47 where there is no canopy bow. No, put the blob on the INSIDE!!)
In a correct turn, they would roll in, keeping the horizon on the same imaginary point. But the canopy bow is off to the side, bringing in a parallax error. Left turn, the dopey students see the canopy point is below the horizon. So, they pull the nose up and the nose is high. Right turn, nose is low.
This error is in addition to any aerodynamic reason that may exist.
