This study aimed to evaluate the effects of video materials of para-athletes shown during physical education classes on high school students’ perception of people with physical disabilities. On February 16 and 19, 2021, 26 students in their second year of high school took part in a Paralympic Education class. Pre- and post-class, we conducted a questionnaire survey comprising 17 items that could be categorized into three perspectives: (1) whether students viewed people with physical disabilities as socially disadvantaged; (2) whether they respected them; and (3) whether they sympathized with them. The participants were asked to provide a rating on a seven-point scale for each question. The differences in the mean values recorded before and after class for each perspective were analyzed using corresponding t-tests. We made the following findings: (1) The classroom practice using video materials of para-athletes had a positive impact on the students’ perception of people with disabilities as socially disadvantaged and their sympathy toward them. We believe that this was due to the use of video materials showing the high level of athletic ability of para-athletes, their background, and their way of thinking. (2) The use of video materials of para-athletes had little influence on the students’ respect for people with physical disabilities. We believe this was because the teacher questioned the excessive praise for the efforts and achievements of para-athletes during class. (3) After the class, most of the students’ understanding of disability remained at the third level of emotional understanding. None of the students’ understanding of disability reached the fifth level of accepting behavior.
