Just the moment a spirit of back-talk is observed cease all ordinary
conversation with the child. Use signs almost wholly to indicate your
wishes and back them up with a demeanor and general program that checks
all opportunity for a spectacular prank. Dismiss the pupils for recess
or assign some duty that engages all the other pupils while you deal
with the insurgent pupil alone. Immediate action is necessary, even if
it is nothing more than to excuse the pupil from any further school work
for the time being.
Treat the pupil who talks back as you would an invalid to be cured
rather than as a criminal to be _paid_ back, thus laying aside all
evidence of hostility or displeasure; assume that his disability
necessitates separation from the others. Use pleasant conversation as a
means of establishing his confidence in you.
