The purpose of this study was to analyzed the effect of small group based on-the-job
training through prompting of supervisors on job rotation skills of workers with
intellectual disabilities living in group homes. To do so, the study selected three workers
with intleectual disabilities who had worked part-time in a lunch factory for 3 years after
graduating from the majoring course and high school course of special education schools
as study subjects. The experimental environment was side dish makings task room in
lunch factory. This study was conducted as a single subject research, and the
experimental design was a multiple probe design across subjects. In addition, the
experimental conditions were divided into three types including baseline, intervention and
maintenance. Small group based on-the-job training through prompting of supervisors was
used as independent variable to create instructional method based on response prompting
through direct instruction, picture modeling, and demonstration through video modeling.
Also in the independent variable of this study, three instructional methods were applied
with mutually connected procedure and comprehensive system. Job rotation skills, the
dependent variable, was operationally defined as cooking of fried kimchi by the subjects.
As a result of this study, the subjects were found to effectively acquire job rotation skills,
the dependent variable, through the intervention of supervisors. In addition, the subjects
effectively maintained the target behavior acquired until 4 weeks after the end of the
intervention. The results showed that there is a significant functional relationship
between the small group based on-the-job training through prompting of supervisors and
job rotation skills of workers with intellectual disabilities.
