The purpose of this study was to train teachers and peers to increase social interactions of children who had been identified as having a lack of social interactions in an inclusive preschool in Korea. Four children with disabilities were identified by teachers as lacking social interactions with peers and teachers, and were the focal subjects of the study. The focal children, four teachers, and four classes of peer children participated in two interventions, an initial training on naturalistic teaching strategies with teachers and a training on social skills with peer and focal children, and a combined intervention. A multiple probe design was employed to examine effects of the two interventions during free choice play periods. The four teachers were trained on naturalistic teaching strategies, and peers and focal children in each class participated in a training on social interactions for the first intervention phase. The second intervention was a combined intervention consisting of both naturalistic teaching strategies of teachers and a ‘group game’ in which peer children used social interaction skills with focal children. This study consisted of baseline I, training teachers and children with baseline II, the combined intervention, and the maintenance phase. The results of this study indicate that focal children’s mean percentage of social interactions with teachers and peers in free choice play periods increased from baseline I after the initial training with baseline II. The maintenance phase indicated that mean percentages of social interactions of focal children increased from the mean percentages of social interactions in baseline I. This study may contribute to issues of training teachers on naturalistic teaching strategies and children on social skill interactions in an inclusive preschool in Korea, and the United States, for promoting social interactions with children with disabilities. / text

Physical education is important to promote physical activity of adolescents with and without disabilities, but many adolescents are not active during physical education classes. Innovative instructional strategies are imperative to change this phenomenon, but it will be challenging to develop effective instructional strategies without thorough understanding of students' physical activity behavior in physical education settings. Two studies were conducted to comprehensively understand physical activity behavior of adolescents with and without disabilities in inclusive physical education classes at middle schools. The first study investigated the utility of the integrative theory to predict students' physical activity intentions and behavior at the intrapersonal level. A total of 577 participants, including 24 adolescents' with disabilities, were recruited from 8 middle schools in Korea. In a prospective design, participants' psychosocial constructs and physical activity data were collected by survey questionnaires and electronic pedometers. A multilevel (design-based) structural equation modeling using maximum likelihood estimation with robust standard error correction found that students' attitudes, subjective norms, and barrier-efficacy significantly predicted students' goal intentions. Students' implementation intentions and task-efficacy were significant predictors of physical activity behavior. In addition, implementation intentions completely mediated the relationship between goal intentions and physical activity behavior. The second study investigated three conceptual models, including process-product model, student mediation model, and ecological model, to predict students' physical activity behavior at the interpersonal and environmental levels. A total of 13 physical educators teaching inclusive physical education and their 503 students, including 22 students with disabilities, were recruited from 8 middle schools in Korea. A series of multilevel (model-based) regressions with maximum likelihood estimation showed that the ecological model was the most effective model in prediction of students' physical activity behavior. Specifically, it was found that teachers' teaching behavior and students' implementation intentions were significant predictors of the students' physical activity behavior when interacted with gender, disability, lesson contents, instructional models, and class locations. In conclusion, findings suggest that intrapersonal, interpersonal, and environmental predictors provide a systematic account in the understanding of students' physical activity behavior in physical education settings. Future studies should consider all three factors simultaneously to effectively develop instructional strategies that promote physical activity of adolescents' with and without disabilities in physical education classes. / Graduation date: 2013
