The Working Memory Rating Scale (WMRS) was designed as a behavioral rating tool to assist teachers in identifying students at risk of working memory difficulties. The instrument was originally normed on 417 monolingual English-speaking children from the United Kingdom. The purpose of this study was to test the reliability and validity of the WMRS…

Children learning English as an additional language (EAL) often experience difficulties with reading comprehension relative to their monolingual peers. While low levels of vocabulary appear to be one factor underlying these difficulties, other factors such as a relative lack of appropriate background knowledge may also contribute. Sixteen children…

Although the research literature regarding language growth trajectories is burgeoning, the shape and direction of English Language Learners' (ELLs) language growth trajectories are largely not known. This study used growth curve modeling to determine the shape of ELLs' language growth trajectories across 12,248 oral narrative language samples…

This study examines vocabulary growth rates in first and second languages for Spanish-speaking and Cantonese-speaking English language learners from kindergarten through second grade. Growth-modeling results show a within-language effect of concepts about print on vocabulary. Language exposure also had an effect on English vocabulary: earlier…

Autism spectrum disorders (ASD) are associated with many different levels of language and social impairment, differences in levels of cognitive impairment, varying levels of aberrant behavior, and discrepancies in the presence or amount of restrictive and repetitive behavior. The heterogeneity found within the ASD population is coupled with…

This study investigated the effects of discussion on vocabulary learning from expository text read alouds. This study used a pre-/post within-subjects design to investigate whether discussion contributed to improved vocabulary knowledge from expository text read alouds and whether the placement of discussion makes a difference in vocabulary…

This study grew from a need identified by professionals working in the same community to explore interagency support for augmentative and alternative communication device implementation with students, families, and professionals involving the local school system and university. A case study was used to document intervention with a second-grade…

Genetic and environmental relations between vocabulary and reading skills were explored longitudinally from preschool through Grades 2 and 4. At preschool there were strong shared-environment and weak genetic influences on both vocabulary and print knowledge but substantial differences in their source. Separation of etiology for vocabulary and…

This study considered the efficacy of a differentiated approach to vocabulary instruction for learners with word-finding difficulties (WFD) in the speech and language pathologist's room. Using a pretest-posttest design to study treatment outcomes, 10 second graders with WFD received first semantic-based vocabulary instruction (S) and then…

This study tests the extent to which giving credit for African American English (AAE) responses on a General American English sentence imitation test mitigates dialect effects. Forty-eight AAE-speaking second graders completed the Recalling Sentences subtest of the Clinical Evaluation of Language Fundamentals-Third Edition (1995). A Bayesian…

Purpose: Some researchers (F. R. Vellutino, F. M. Scanlon, & M. S. Tanzman, 1994) have argued that the different domains comprising language (e.g., phonology, semantics, and grammar) may influence reading development in a differential manner and at different developmental periods. The purpose of this study was to examine proposed causal…

This study compared the abilities of children with specific language impairment (SLI; n=10) and typically developing (TD) children (n=13) to access and participate in an ongoing interaction between two unfamiliar peer partners. Results revealed that all children in the study accessed by either making an unprompted initiation toward their peers…

Development of English- and Spanish-reading skills was explored in a sample of 251 Spanish-speaking English-language learners from kindergarten through Grade 2. Word identification and reading comprehension developed at a normal rate based on monolingual norms for Spanish- and English-speaking children, but English oral language lagged…

The authors examined (a) the extent to which kindergarten estimates of core language functions predicted teacher ratings of behavior problems in each of the child's first 4 years of elementary school and (b) the ability of core language measures to predict concurrent behavior problems at each of the early elementary school grades studied.…
