Abstract：To explore the impact of teaching video playback speed on the learning effect of hearing-impaired collge students，this study adopts behavioral test and eye movement tracking techniques to measure the learning performance and the visual atention process. 57 hearing-impaired college students are randomly assgned into experiments with three speed levels （fast，medium and slow）.The results showed that during the multimedia learning process，the playback speed of videos not only affects the attention process of hearing-impaired college students，but also afects deep cognitive processing.Playing teaching videos at a slow speed can help improve he academic performance of hearing-impaired collge students，reduce cognitive load，and increase average duration of fixations and the number of fixations of the picture AOI（area of interest）.
