"학생이 의자를 돌려요."
Translation:The student turns the chair.
So from my pieced together notes (not sure how correct I am but this is what I've gathered from repeating this section):
To Turn (The corner, or like, your body, or whatever object) 돌다
To turn (Rotate/Spin) 돌리다
To return (Come back) 돌아오다
To return (An object to a place/person) 돌려주다
