2nd rate teachers just consider how you play not the method and do not scrutinize how you get to that point.
Ask your teacher to observe how you to practice the piano, not play. Show him in one lesson what you would do on your own without him there to help you, let him observe how you tackle learning or improving your fingering/notes yourself, ask him if your approach to solving problems in the music is effective and efficient. Some teachers if asked how to practice a piece will start teaching you this, if you don't say anything they might expect that you know, however all good teachers I have been taught by encourage refinement to our practicing methods (learning the fingering/notes) as well as our playing. 2nd rate teachers just consider how you play not the method and do not scrutinize how you get to that point (although for the most advanced students they might be more interested in sound since their learning craft is already developed, however even these students can benefit from some refinement to their practice approach).
...it is much more nice and easy to sit and listen someone playing than doing your supposed job.
Thanks for helping!
