I believe the answer is:

rote

(Other definitions for rote that I've seen before include "mindless activity?" , "Unthinking repetition" , "Learn by . . . . to have off by heart" , "Repetition for learners" , "Mechanical repetition (as a means of learning)" .)

I've seen this clue in The Wall Street Journal.
