Language and Reading Progress of Young Deaf and Hard-of-Hearing Children.

We examined the language and reading progress of 336 young DHH children in kindergarten, first and second grades. Trained assessors tested children's language, reading, and spoken and fingerspelled phonological awareness in the fall and spring of the school year. Children were divided into groups based on their auditory access and classroom communication: a spoken-only group (n = 101), a sign-only group (n = 131), and a bimodal group (n = 104). Overall, children showed delays in language and reading compared to norms established for hearing children. For language, vocabulary standard scores were higher than for English syntax. Although delayed in language, children made expected gains based on hearing norms from kindergarten to second grade. Reading scores declined from kindergarten to second grade. Spoken-only and bimodal children had similar word reading and reading comprehension abilities and higher scores than sign-only children. Spoken-only children had better spoken phonological awareness and nonword reading skills than the other two groups. The sign-only and bimodal groups made similar and significant gains in ASL syntax and fingerspelling phonological awareness

Strategic and Interactive Writing Instruction: An efficacy study in grades 3-5

A quasi-experimental study was conducted to examine the impact of Strategic and Interactive Writing Instruction on 3rd-5th grade deaf and hard of hearing students’ writing and language compared to a business-as-usual condition (N=63). A total of 18 hours of instruction was provided for each of two types of writing—personal narrative (known as recount) and persuasive. Writing samples, collected prior to instruction and after, were scored for writing traits, language accuracy and complexity. Data were analyzed using a two-level, mixed-effects regression. Results show the treatment to be effective for recount and persuasive writing traits, and recount language variables, with effect sizes ranging from 0.46 to 2.01. Treatment effects were also substantial for persuasive writing language outcomes (0.38 to 1.06), although not all were statistically significant at the 0.05 level. The findings suggest the importance of apprenticeship in writing and consideration for the specific language needs of students with hearing loss

Strategic and Interactive Writing Instruction: An Efficacy Study in Grades 3-5

A quasi-experimental study was conducted to examine the impact of Strategic and Interactive Writing Instruction on 3rd-5th grade deaf and hard of hearing students’ writing and written language compared to a business-as-usual condition (treatment group N = 41, comparison group N = 22). A total of 18 hours of instruction was provided for each of two types of writing—personal narrative and persuasive. Writing samples, collected prior to instruction and after, were scored for writing traits, written language accuracy, and complexity. Data were analyzed using a two-level, mixed-effects regression. Results show the treatment to be effective for personal narrative and persuasive writing traits, and personal narrative written language variables, with effect sizes ranging from 0.46 to 2.01. Treatment effects were also substantial for persuasive writing written language outcomes (0.38 to 1.06), although not all were statistically significant at the 0.05 level.

An Item Response Curves Analysis of the Force Concept Inventory

Several years ago, we introduced the idea of item response curves (IRC), a simplistic form of item response theory (IRT), to the physics education research community as a way to examine item performance on diagnostic instruments such as the Force Concept Inventory (FCI). We noted that a full-blown analysis using IRT would be a next logical step, which several authors have since taken. In this paper, we show that our simple approach not only yields similar conclusions in the analysis of the performance of items on the FCI to the more sophisticated and complex IRT analyses but also permits additional insights by characterizing both the correct and incorrect answer choices. Our IRC approach can be applied to a variety of multiple-choice assessments but, as applied to a carefully designed instrument such as the FCI, allows us to probe student understanding as a function of ability level through an examination of each answer choice. We imagine that physics teachers could use IRC analysis to identify prominent misconceptions and tailor their instruction to combat those misconceptions, fulfilling the FCI authors\u27 original intentions for its use. Furthermore, the IRC analysis can assist test designers to improve their assessments by identifying nonfunctioning distractors that can be replaced with distractors attractive to students at various ability levels

A bilingual advantage in 54-month-olds’ use of referential cues in fast mapping

Research has demonstrated a bilingual advantage in how young children use referential cues such as eye gaze and pointing gesture to locate an object or to categorize objects. This study investigated the use of referential cues (i.e., eye gaze) in fast mapping in three groups of children that differed in their language exposure. One hundred and seven 54-month-old children who were English monolinguals (n=29), English-Mandarin bilinguals (n=48), and English-Mandarin bilinguals with exposure to a third language (i.e., trilinguals, n=31) were assessed with a wordlearning task using two types of tests – a referent test and a mutual exclusivity test. During the task, following the gaze of an adult speaker was needed to be able to indicate the correct referent of a novel word at test. All three groups of children demonstrated successful word learning in explicit selection of and implicit looking time toward the target object during testing. However, bilingual and trilingual children outperformed their monolingual peers in both types of tests when they were asked to explicitly select the correct objects. These findings suggest positive effects of bilingualism on children’s use of referential cues in fast mapping

Environmental contributions to disparities in pregnancy outcomes.

One of the most persistent disparities in American health status is the pronounced difference in birth outcomes between non-Hispanic black and non-Hispanic white women. Poor pregnancy outcomes have a substantial impact on mortality, morbidity, and health care costs. Increasing evidence indicates that environmental exposures are associated with poor birth outcomes. This paper reviews the latest research on how environmental exposures affect pregnancy outcomes and then discusses how these exposures may be embedded within a context of significant social and host factor stress. The analysis suggests that environmental, social, and host factors are cumulatively stressing non-Hispanic black women and that this cumulative stress may be a cause of the persistent disparities in pregnancy outcomes

Specialized writing instruction for deaf students : A randomized controlled trial

Strategic and Interactive Writing Instruction (SIWI) involves teaching cognitive writing strategies and apprenticing novices within collaborative writing communities. It is responsive to deaf students' diverse language experiences through embedded metalinguistic/linguistic components. A randomized controlled trial of SIWI was conducted with 15 teachers and 79 students in grades 3-5. Recount, information report, and persuasive genres were taught across three 9-week periods. Writing samples analyzed for writing traits, language clarity, and language complexity were collected prior to instruction for the genre, immediately following, and 9 weeks after withdrawal of instruction for the genre. Standardized writing measures and motivation surveys were collected at the beginning and end of the academic year. Genre-specific writing outcomes were statistically significant for recount and information report writing, with substantial effect sizes for treatment and maintenance. Standardized writing outcomes mirrored these results. All others variables demonstrated small to moderately large treatment effects, although not all statistically significant
