Mac,. .It is something that you just have to keep chipping away at. At the end of the day all you can do is advise the student of what they are doing is not correct and let them realise in their own time. A good way to teach is to get the to slow every manouver down to a point where it is rediculus(?). Get them to say BANK then have a pause then BALANCE they do that and have a pause then get them to say ATTITUDE then hold it the whole way around. Whilst in the turn you have to get them to conciously be cheching the attitude and also the performance ie: AOB,ALT,ASI,Slip indicator. After all power+attitude = performance and all the rudder does is increase the performence. If they want to fly out of ballance all day who cares.
