생활지원중심 개별화교육계획(IEP)에 기반한 다요소행동중재가 지적장애학생의 자리이탈행동과 과제수행행동에 미치는 영향

Abstract

The purpose of this study was to investigate the effects of multi-component behavioral interventions based on life support-oriented Individualized Education Plan(IEP) on the out-of-seat and task performance behavior for student with intellectual disabilities. The independent variable in this study was the multi-component behavioral intervention based on a life support-oriented IEP, and the dependent variables were out-of-seat behavior and task performance behavior. The study was conducted using an AB design, consisting of baseline, intervention, and maintenance phases. After establishing a life support-oriented IEP in the research preparation stage, observers were trained, problem behavior selection and functional behavior evaluation (FBA) were conducted, reinforcement evaluation was conducted, and a behavioral intervention plan(BIP) based on life support-oriented IEP was developed. Baseline, intervention, and maintenance phases were conducted in special education classrooms, with data collection occurring from 10 minutes after class started to 30 minutes afterward. Analyses were conducted in terms of level, immediacy, trend, averages and ranges, and Percentage of Non-overlapping Data(PND). Qualitative aspects of the dependent variables were analyzed in-depth through anecdotal analysis. The results showed that the multi-component behavioral intervention based on the life support-oriented IEP was effective in reducing out-of-seat behavior and increasing task performance behavior. These effects were maintained after the intervention ended. Based on the results, implications were discussed with limitations and suggestions for future research.
