Effects of PowerPoint Presentations on Reading Comprehension of Deaf and Hard of Hearing Students in Iranian Exceptional High Schools
It is becoming increasingly difficult to ignore the role of PowerPoint presentation on reading comprehension of deaf and hard of hearing (D/HH) students in schools. Based on different studies, PowerPoint, a common multimedia tool, has a crucial role in teaching and learning through providing a suitable understanding of the text and motivating students. The present study aimed to examine the predictive effects of PowerPoint presentations on reading comprehension of D/HH students. As reported in the literature, reading levels of deaf high school students are equal to those of fourth grade hearing students. Therefore, a visual computer-mediated approach was implemented to monitor the reading comprehension progress of 20 D/HH students in Iranian high schools. The reading comprehension of the experimental and control groups were compared by conducting the Stanford Achievement Test and applying paired t-tests. Our findings indicated a significant difference between the mean reading comprehension scores of the two groups.
