I believe the answer is:
rote
'repetitive learning method' is the definition.

This is all the clue.
(Other definitions for rote that I've seen before include "performance based solely on routine" , "Learn by . . . . to have off by heart" , "Habitual routine" , "Mechanical routine" , "Repetition of something to be learned" .)
