| Summary: | 碩士 === 國立臺北科技大學 === 技術及職業教育研究所 === 102 === Severely visually disabled students were disadvantaged, especially in math performance, due to physical obstacle and the way they were assessed. In order to enhance their performance, the present study proposed to incorporate audio-descriptions to math problems as effective assessment accommodation.. Therefore, the purposes of study are to gauge the effectiveness of 1) braille test accompanied by 3-D graphics and additional audio descriptions, and 2) audio test, accompanied by 3-D graphics and additional audio descriptions on severely visually-impaired students’ understanding of math graphics
In this study, a single-subject research design was adopted and two severely visually-impaired students participated. Data were collected and analyzed through three phases, including baseline (A1, A2) and intervention (B1). The results showed that the provision of additional audio description worked well on both participants’ understanding of two-dimensional and three-dimensional graphs, and their response time per test item was around average as compared to that when they were tested without the accommodations.
