The purpose of this study was to analyze the status and perceptions of online classes of special education teachers who experienced the non-face-to-face online classes due to COVID-19. This study also explored the ways to implement online classes more effectively for students with disabilities. A total of 101 special education teachers participated in an online survey for this study who enrolled in elementary, middle, and high schools. The key results of this study were as follows. First, the online contents were most widely used during COVID-19. Second, special education teachers perceived the provision of learning packages was the most effective methods in online classes. Third, special education teachers regarded real-time interactive online classes(e.g., using Zoom) as the most appropriate ways of future online classes. In addition, individualizing class and building platforms that could organize portfolios by students were perceived as essential elements for the effective online classes. Fourth, the difficulties that special education teachers experienced during the online classes were content development and data production. The most serious problem that students experienced was class concentration. Fifth, special education teachers perceived that online classes had positive effects on students’ learning. Particularly, they liked various videos and online contents developed during COVID-19. However, the negative effects of the non-face-to-face classes also reported such as ‘lots of students were left alone without enough cares at home’.
