Abstract
This study was conducted to develop an order recovery program in a school by means of the applied
behavior analysis. This method decreases the problem action of the student by increasing his/her
prospective actions. This study was carried out to restore the order of a certain public junior high school.
A lot of students who had a developmental disability were registered at the school. And the order of the
school was disturbed by the problematic actions of these students with developmental disabilities. As a
result of having carried out this study, (a) the number of problem actions decreased and (b) the problem
action was degraded from higher one to lower one.
