Research evaluating augmentative and alternative communication (AAC) options shows general support for various strategies (e.g., manual sign, picture exchange) in teaching individuals with autism (ASD) and intellectual disabilities (ID) to request basic wants and needs. However, the overall quality and quantity of research is diluted by the…

The main research question of this dissertation is the nature of language interaction effects observed in linguistic patterns of multilingual children. Such effects--often described as syntactic transfer/influence of one of the languages on the other--have been richly documented in the multilingualism literature. I review an influential model…

This case study explores the relationship between teachers' language knowledge and their grammar teaching practices within the context of a bilingual school for the deaf in Sweden, a country that has demonstrated success in educating deaf children bilingually in written Swedish and Sweden's signed language. The study's participants were two…

The purpose of this study was to analyze attitudes and perspectives of university students towards D/deafness before and after studying American Sign Language, ASL, and to determine if any relationship between them exists. A double pre-test quasi-experiment design was used with participants who were students enrolled in a basic ASL course at a…

This study examines Deaf parents with children who have cochlear implants on their beliefs and perspectives of bilingualism in American Sign Language and English using complementary mixed methods through surveys and follow-up interviews. Seventeen families participated in the survey and eight families continued their participation in semi-formal…

This qualitative ethnographic Linguistic Landscape (LL) study collected and analyzed ten individual "walking tour" interviews with residents of Memphis, Tennessee, exploring the personal thoughts and feelings about linguistic changes in the communities triggered by the LL. The researcher focused the participants' attention on…

Lange (1988) has defined "articulation" as "the interrelationship and continuity of contents, curriculum, instruction, and evaluation with programs which focus on the progress of student in learning to both comprehend and communicate in a second language" (p. 16-17). It is the continuity of one course to the next without…

Bilinguals sometimes outperform age-matched monolinguals on non-language tasks involving cognitive control. But the bilingual advantage is not consistently found in every experiment and may reflect specific attributes of the bilinguals tested. The goal of this dissertation was to determine if the way in which bilinguals use language, specifically…

The current phenomenological case study, based in part on Vygotsky's sociocultural theory, set out to examine the lived experiences of individuals sharing and mediating meaningful communication with individuals who have Down syndrome. To accomplish this, the researcher interviewed several categories of caregivers who regularly interact with…

The effectiveness of using American Sign Language (ASL) handshape stories to teach word recognition in whole stories using a descriptive case study approach was explored. Four profoundly deaf children ages 7 to 8, enrolled in a self-contained deaf education classroom in a public school in the south participated in the story time five-week…

American Sign Language (ASL) is the natural and preferred language of the Deaf community in both the United States and Canada. Woodward (1978) estimated that approximately 60% of the ASL lexicon is derived from early 19th century French Sign Language, which is known as "langue des signes francaise" (LSF). The lexicon of LSF and ASL may…

Current studies on language and literacy in hearing children have pointed to face-to-face linguistic interaction as one crucial factor in the emergence of literacy. Studies that explored the language and literacy of preschool children, both in the their homes and in school, have found that the kind of talk and the quality of talk that transpires…

Many prior studies conducted in museums have focused primarily on exhibits as the main objects for learning. Less progress has been made in studying signage as another meaning-making tool in museums. The present study was designed to understand the role of signage in family learning by answering the following research questions, "How does signage…

Researchers have noted that mathematics achievement for deaf and hard-of-hearing (d/hh) students has been a concern for many years, including the ability to problem solve. This quasi-experimental study investigates the use of the Exemplars mathematics program with students in grades 2-8 in a school for the deaf that utilizes American Sign Language…

This dissertation examines a project to unify sign languages across twenty-two Arab countries. Proponents of the project, mainly pan-Arab governmental bodies with the support of members of the staff at the Al Jazeera satellite network, have framed the project as a human rights effort to advance the welfare of deaf Arab people. They have urged its…
