This study is an intervention study to investigate the effect of physical activity through sensory integration psychological exercise on exercise ability and self - efficacy of developmental disabilities students. The subjects were 2 autistic students with disabilities and 2 students with intellectual disabilities. The subjects were interviewed for 2 or 3 times a week for a total of 24 sessions. In addition, after the intervention, the effect of intervention was verified by checking the maintenance after 2 weeks' rest period The results of the study are as follows. First, the sensory integration psychological movement showed improvement of the exercise ability by positive scores of all the four subjects of the developmental disabled students. In particular, autistic students showed the highest athletic performance. The students with intellectual disability students had the lowest score of the athletic ability among the 4 students, but the rate of the improvement of the personal inward posture was the highest. Second, intervention of physical activity through sensory integration psychological exercise showed improvement of self - efficacy in all four students. Self - efficacy was assessed using a 5 - point scale. In the pre-test of the total 23 items, the mean score of the average students was 1.5-2.2, but after the intervention, the post-test showed a high score of 3.3-3.6. All four students showed positive self-efficacy The effect of the change was observed. In the maintenance stage test, it was confirmed that exercise ability and self - efficacy were maintained. The results of this study suggest that the sensory integration psychological exercise is effective in improving the exercise ability and positive self-efficacy of the developmental disability students.

This study conducted a survey on teachers of students with visual impairments for their satisfaction, validity in the National Evaluation System for Teachers' Proficiency and Development. The intention of this research is to provide fundamental resources for betterment in the practice of evaluation system. Summarized results from the research are as follows. First, the perception of teacher validity indicated higher scale score in teachers with less than 5-year of teaching experience, and teachers without visual impairment. Additionally, in the perception of teacher satisfaction in school for students with visual impairment demonstrated higher scale score from the background variables that who were in pre-school, elementary level, possess less than 5-year of teaching experience, and teachers without visual impairments. Therefore, both validity about the teacher evaluation system and teacher satisfaction is effected that develop in teaching profession not only in general education schools but also in schools for students with visual impairments. Second, the results validity and teacher satisfaction in national evaluation system illustrated a positive correlation with every aspect. Additionally, validity of assessment factors and validity of assessment process shown the highest correlation above all factors, and the assessment process satisfaction and the satisfaction of results shown the highest correlation above all factors. As a result, validity and teacher satisfaction in the national evaluation system addressed a mutual affirmative relation that the researcher proposed a follow-up study from the consequences.

The purpose of this study is to explore the successful implementation of teachers and participation of students in UDL-based middle school science classes. In order to do this, participants were observed in UDL-based science classes and general science classes at middle schools and the contents were analyzed using Korean-style UDL checklists(Kim Nam-jin, Kim Yong-wook, 2012). The results are as follows: First, UDL-based science classes are more effective than regular science classes. However, there was prejudice and misunderstanding regarding UDL. They misunderstood the use of technology as UDL. If you buy UDL, you are using UDL. UDL implementation begins with the creation of learning environments and learning development, not product use. If UDL is not reflected in the study design even if UDL is purchased, it is not a UDL-based class. Second, successful participation of students in UDL-based middle school science class. In UDL-based science classes, students actively participated in the classes. He attended classes more often than ordinary science classes. Third, it is urgent to set up standards to evaluate Korean classes by supplementing the problems found in the Korean-style UDL Checklist used as analysis data. After all, I will say that successful implementation of teachers and participation of students in UDL-based science classes can be implemented through science classes based on UDL principles and guidelines.
