Stargardt Disease was identified by German ophthalmologist Karl Stargardt in 1901. It is the most commonly inherited macular dystrophy condition (Light et al., 2017), with an estimated worldwide prevalence of 1 in 8,000 to 1 in 10,000 (Cai et al., 2018). Stargardt Disease is the juvenile version of macular degeneration (Daly, 2014), with its early…

It is difficult to read mathematical expressions in braille, whether or not in coordination with text to speech (TTS) synthesis. The researchers in this study investigated the effect of an intervention on the braille readers' performance in reading and comprehending mathematical expressions as well as the braille readers' ability to make…

This article reports on a study that examined whether vocabulary flashcards facilitate spelling acquisition. The study was designed to evaluate whether students who are blind can learn to spell words accurately and incidentally when academic vocabulary instruction is used. Auditory information was provided prior to the introduction of a flashcard,…

Introduction: Participants' perspectives are valuable in evaluating the effectiveness of an intervention. Methods: Interviews were conducted with teachers of students with visual impairments and students who completed an intervention designed to build graphics literacy skills. Results: Six themes were identified with corresponding subthemes. The…

Introduction: "Reading Adventure Time!," formerly known as the pilot version of the "iBraille Challenge Mobile App," is an educational technology tool integrating digital literacy to support braille reading and writing instruction for students in 1st-12th grades. Designed to operate on an Apple iPad with a refreshable braille…

Introduction: Constant time delay has been identified as an evidence-based practice to teach print sight words and picture recognition (Browder, Ahlbrim-Delzell, Spooner, Mims, & Baker, 2009). For the study presented here, we tested the effectiveness of constant time delay to teach new braille words. Methods: A single-subject multiple baseline…

Introduction: Constant time delay is an evidence-based practice to teach sight word recognition to students with a variety of disabilities. To date, two studies have documented its effectiveness for teaching braille. Methods: Using a multiple-baseline design, we evaluated the effectiveness of constant time delay to teach highly motivating words to…

Introduction: This study evaluated the usability and effectiveness of an artificial intelligence Braille Tutor designed to supplement the instruction of students with visual impairments as they learned to write braille contractions. Methods: A mixed-methods design was used, which incorporated a single-subject, adapted alternating treatments design…

Educators of students with visual impairments have long advocated that children who read and write in braille benefit from access to and use of a braille note-taker (BNT) with refreshable braille display. However, little research exists that evaluates whether using a BNT impacts literacy. In this single-subject study, authors investigated if using…

Research on literacy instruction for students with multiple disabilities is limited. Empirical research on braille instruction for students with multiple disabilities that include congenital blindness is virtually nonexistent. This case study offers initial insight into possible methods of early braille literacy instruction for a student with…

This article tells the story of how Colby, a young boy who is congenitally deafblind, developed language and literacy. Narrative is coupled with video to illustrate how the following four instructional approaches and interventions supported his development: (1) daily schedule, (2) home-school journal, (3) experiential based literacy, and (4)…

Six primary school-aged braille students were taught to name 4 to 10 braille letters as phonemes and another 4 to 10 braille letters as graphemes (Study 1). They were then taught to name 10 braille words as onset-rimes and another 10 braille words as whole words (Study 2). Instruction in phonemes and onset rimes resulted in fewer trials and a…

Three blind university students used a computer-generated tachistoscope-like display of electronic braille in an effort to increase reading speeds. Results did not indicate conclusively that such a program is effective in increasing reading speed while maintaining comprehension or in maintaining speed following the withdrawal of treatment. (JDD)
