This study set out to investigate whether Visual Input Enhancement (VIE) as a pedagogical intervention increases the comprehensibility of reading text of students’ course book. To accomplish this study 10 female deaf students in first grade of Nezam Mafi High School, special for deaf and hard of hearing impairments, were chosen nonrandomly due to their few numbers. The materials exploited during treatment sessions were four reading texts from students’ course book. After considering difficulty and readability of the texts through software named “Text Analyzer”, two out of four texts were enhanced via supportive colored pictures. Also new vocabularies were manipulated through typographical cues such as boldfacing, italicizing, and highlighting. After teaching period, two reliable and validated post-tests were administered, one test for the two enhanced texts and the other one based on the two unenhanced reading texts. The collected and analyzed data via “Wilcoxon Signed Ranks Test” revealed that the differences between the two posttests was significant enough (p= 0.002<0.05) to reject the null hypothesis and it is proved that using Visual Input Enhancement in English reading texts for deaf students has a significant effect on their reading comprehension.
