    is correct that there is a distinction between the method used to teach ballet and the technique used to dance ballet.  Different schools may teach the same type of dance in significantly different ways.   is correct that significant ambiguity can exist between the two.  How dance is taught affects how dance is performed, which affects how dance is choreographed, which affects how dance is taught, ad infinitum.   Therein lies the inherent ambiguity.  Where lines between instruction method and performance method are relatively clear, attempts to point out the distinctions would be valuable, though I am not qualified to illuminate those distinctions. —
