This study examined the effect of a 1-day, 6-hour key word signing (KWS) workshop on in-service special education teachers' and speech-language pathologists' (SLPs) (a) skill identifying American Sign Language (ASL) signs; (b) skill producing ASL signs; (c) use of KWS in the classroom or therapy room; and (d) perceived changes from taking part in…

Signing systems that attempted to represent spoken language via manual signs -- some invented, and some borrowed from natural sign languages -- have historically been used in classrooms with deaf children. However, despite decades of research and use of these systems in the classroom, there is little evidence supporting their educational…

This article explores the available research literature on language development and language interventions among deaf and hard of hearing (d/hh) children. This literature is divided into two broad categories: Research on natural languages (specifically American Sign Language and spoken English) and research on communication systems (specifically…

Because sign languages have two main articulators, signers simultaneously experience both possibilities and constraints in the articulation and perception of linguistic messages. Sign languages commonly convey different linguistic units with each hand, and additional information is conveyed in nonmanual signals. Meaningful perseverations (or sign…

Deaf and hard-of-hearing (DHH) literature, including the reading behaviour of Deaf adults, suggests that Teachers of the deaf (TODs) read different amounts of text during read alouds to DHH prereaders based on the spoken and visual communication modes DHH prereaders use, such as: American Sign Language (ASL), only spoken English (speech),…

For d/Deaf and hard-of-hearing prereaders who communicate predominately in spoken and/or signed English (DHH-English), Teachers of the d/Deaf (TODs) read books aloud to increase English skills, auditory-verbal comprehension, sequencing skills, verbal reasoning, background knowledge, and sight word recognition. Teachers struggle to select…
