One method of bringing about this formation of good habits is to have
each pupil keep a list of his _own_ “demons.” Each pupil’s list will be
different, for many words are “demons” for one pupil but not for
another. This list may include root words and derivatives, or only
derivative words. Each pupil should be required to keep his own list on
which he, personally, may be tested from time to time to see if he has
mastered the words that have proved difficult for him to learn. This
list should not include the words that have been misspelled
accidentally.
Writing misspelled lists as a punishment should _be absolutely
forbidden_.
