A cohort of 223 d/Deaf and hard of hearing (d/Dhh) students in grades 3-9 in special education schools took…

Teachers of the d/Deaf (TODs) struggle to select appropriate storybooks for elementary-aged Deaf pre-readers who use American Sign Language (Hayes & Shaw, 1994).

A systematic review explored the evidence base of literacy intervention studies that examined the early years of schooling (preschool through first grade) of participants who were d/Deaf or hard of hearing (d/Dhh). Specific inclusion criteria were used to select single-case design (SCD) studies published in peer-reviewed journals between 2004 and…

The study examined the efficacy of an early intervention program to improve children's sequential time perception through virtual versus pictorial training in arranging episodes of temporal scripts. The researchers examined 65 deaf and hard of hearing children ages 4-7 years who were divided into two groups: (a) virtual environments technological…

The effectiveness of phonological instruction with 6 deaf students in an oral program was investigated. In a previous investigation (Syverud, Guardino, & Selznick, 2009), promising results had been obtained in a case study in which the Direct Instruction curriculum titled "Teach Your Child to Read in 100 Easy Lessons" (Engelmann, Haddox, & Bruner,…
