Since 2005, ‘The First Class of Korea,’ co-produced by the Ministry of Education, First and Foremost Movement for Persons with Disabilities, Radio KBS3, and The Community Chest of Korea, has been one of the foremost broadcast materials aiming to improve disability awareness. Because the material is broadcast in every single school on ‘The Day of Persons with Disabilities’, it has a large influence on students’ perception of the disabled. However, there has been little research concerning how students’ perceptions may have been affected by this broadcast. This study investigates the participants’ changing attitude by analyzing their reflection reports after watching ‘The First Class of Korea (2018).’Data were collected through 286 reports submitted by fifth- and sixth-year students at S elementary school in the city of Incheon. From this data, three main themes emerged—cognitive, affective, and behavioral factors—and we identified fifteen subthemes. In conclusion, on the one hand, the participants attitudes towards the disabled were affected by how the disabled were depicted in the video. On the other hand, they showed a tendency to stick to their existing attitudes towards the disabled regardless of the content of the video. Implications were provided in relation to the development and utilization of video materials for education on improving awareness of the disabled in the future.
