摘要：为探究教学视频播放速度对听障大学生学习效果的影响,采用行为测试和眼动追踪技术,测查了57名听障大学生在快速、中速、慢速3种速度下的学习效果和注意过程。结果发现,在多媒体学习过程中,视频的播放速度不仅影响听障大学生的注意过程,也影响学生的深层次认知加工。慢速播放教学视频有助于提高听障大学生的学习成绩,减轻认知负荷,增加图片兴趣区的平均注视时间和注视次数。
To explore the impact of teaching video playback speed on the learning effect of hearing-impaired college students,this study adopts behavioral test and eye movement tracking techniques to measure the learning performance and the visual attention process.57 hearing-impaired college students are randomly assigned 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 affects deep cognitive processing.Playing teaching videos at a slow speed can help improve the academic performance of hearing-impaired college students,reduce cognitive load,and increase average duration of fixations and the number of fixations of the picture AOI(area of interest).
