비디오 자기모델링 중재가 정신지체 학생의 생산성과 독립적 작업수행 기술에 미치는 영향 = The Effect of Video Self-modeling on production and the skills of independent job performance for students with mental retardation

다국어 초록 (Multilingual Abstract)

The purpose of this study was to examine the effects of video self-modeling intervention on production and independent job performance of students with mental retardation in major course who participated in field practice.
The subjects of this study included three students with mental retardation doing major course. As for study design, time-series design was employed. The intervention environment of video-self modeling used in this study was the sheltered-workshop of industry and academy collaborating companies in community. The duration of a video-self modeling program was eight minutes. The program was practiced by a major course teacher three times a week for four weeks(a total of 12 times).
The production of students with mental retardation was measured using 「production quantity record」and 「production factor record」. In addition, in order to measure independent job performance, 「independent job performance record」and 「independent job performance factor record」were employed. According to time-series, the production and independent job performance were measured before and after the intervention four times each.
The results were summarized as follows.
First, video-self modeling intervention was found to have positive effects on the production of students with mental retardation.
The production of five job tasks(packaging syringe set, syringe sealing work, packaging a syringe after measuring its weight, binding and inserting stopper) were measured using 「production quantity record」. According to the result, all of the three students showed a significant increase in production quantity after the intervention. In addition, the measurement of production factors(composed of 6 questions) was carried out using 「production factor record」. The result showed the three students all obtained more positive evaluation results after the intervention.
Second, video self-modeling intervention was found to have positive effects on the independent job performance of students with mental retardation. Independent job performance of 19 job tasks being carried out was measured using 「independent job performance record」. According to the result, all of the three students received better scores after the intervention. Furthermore, the measurement of independent job performance factors(composed of 6 questions) was conducted using 「independent job performance record」. The three students all obtained improved evaluation results after the intervention.
Based on the study results, the following conclusions and suggestions were made.
First, video self-modeling intervention has positive effects on production and independent job performance. This suggest that future studies should be conducted with setting video self modeling and various task related skill teaching as the independent variable and the dependent variable respectively.
Second, the results of previous studies and this study indicates that production and independent job performance are related. This suggests that future studies on job relate skill factor should examine the relationship between production and independent job performance factor.
Third, this study accessed only three students and used a time-series desire. Therefore, a careful approach should be made in interpreting and generalizing the results. Future studies need to access more subjects and utilize more various study methods to conduct an empirical study that verifies the effects.
