This study asked Teachers of the Visually Impaired to evaluate a shared reading intervention for Students with Intellectual Disabilities and Visual Impairments and how they felt about their preparedness to teach reading. There has been little research on the student population's literacy skills acquisition. For this study, TVIs evaluated stories…

Paraprofessionals need support in successfully implementing literacy interventions to students with visual impairments. This study used a multiple-probe-across-participants design to evaluate the effectiveness of using performance feedback delivered by e-mail to increase paraprofessionals' implementation of constant time delay to teach braille…

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…

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: 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…

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…
