지역사회 내에서 일상생활을 유지하기 위해서는 독립적으로 이동을 할 수 있는 능력과 자신의 시간을 적절하게 관리하는 능력이 누구에게나 공통적으로 요구된다. 따라서 본 연구는 스마트폰을 활용한 문제해결 전략 교수를 제공하면 지적장애 학생의 지하철 이용과 관련된 길 찾기 능력 및 도착 시간 예측하기 능력이 어떻게 변화하는지 알아보고자 하였다. 대상자간 중다간헐기초선설계(multiple probe design across subjects)를 이용하여 예비관찰, 사전교육, 기초선, 중재, 유지, 일반화 단계로 실험을 진행하였다. 연구결과 스마트폰을 활용한 문제해결 전략 교수는 지적장애 학생의 지하철을 이용한 길 찾기 능력 및 도착 시간 예측하기 능력을 습득, 유지, 일반화 시키는데 효과적인 것으로 나타났다. 또한 연구결과를 토대로 스마트폰을 활용한 문제 해결 전략교수 적용 및 향후 연구 과제에 대한 제언들이 논의되었다.
The ultimate goal of special education is to educate students with disabilities to be integrated into communities. Mobility and time managing abilities are required to maintain their own daily life in community. However it`s difficult for them to find their way in support of geographical information and public transport system and to estimate arrival time because they are not good at collecting and using relevant information. In this respect, this study investigated how problem solving strategies with using a smart phone has helped students with intellectual disabilities find their ways to reach destination by subway and estimate arrival time. Multiple probe design across subjects was applied for this study with three middle school students with intellectual disabilities. The intervention was conducted in three parts: observation of performance, outdoor and indoor training. In terms of performance, the students conducted assignments according to the task analyzing steps. When students made the wrong response in a certain step, the observations stopped and outdoor training was applied in order for them to experience all task analyzing steps until the end. Indoor training was next and conducted by using video materials. The training areas where students need for school/recreation activities and family/friends relationships were decided by interviews with them, their peers and family members. Within these areas, they were asked to find the ways at one random sampling point to another point by the subways and to predict the arrival time. The results of this study showed that problem solving strategies using a smart phone was effective to promote mobility and time-management of students with disabilities. To investigate if the effects of the study were generalized in different cities, generalization was tested in Busan. Maintenance of the effects was also checked two and four weeks later after the end of the training. Based on the results, practical implications and future research directions were provided to apply problem solving strategies with a use of smart phone for people with intellectual disabilities in order to help them enjoy their independent and interdependent daily life including various situations at home, school, work and post-secondary education.
