The project was conducted to make an online tutoring program for math word problem solving accessible to students with visual impairments (VI). An online survey of teachers of students with VI (TVIs) guided the decision to provide the math content in the form of an iPad app, accompanied by print and braille materials. The app includes audio descriptions of images that illustrate the math problems, an integrated Scratch Pad, options to adjust color and contrast, hints, and videos showing how to solve sample problems. In order to provide access to those needing screen reading technology or screen enlargement, the app utilizes the Apple built-in accessibility features of VoiceOver and Zoom. A study with 19 TVIs and 29 students with VI was conducted to obtain feedback about the app and materials. Comments were generally positive, but both students and teachers reported that the quality of the hints varied and that the videos were not very helpful. Thus, the hints were revised, and narrated videos showing step-by-step solutions were added to each problem. A single subject study is in progress to compare students’ performance when using the app and materials with the traditional way they access math materials (print, braille).
