Doing the usual 4i effects of controls and had just finished turning so I gave the a/c to the student and suggested we did a "nice gentle 360", after the the obligatory "look-out" the student promptly pulled the stick fully aft.
He thought I meant 360 in the vertical plane.
Do you find that nervous punters "pedal" the a/c down finals?
Had a librarian once who was coming along fine and then on finals on a perfect flying day suddenly wraped his arms around his head and screamed "I can't do this".
