A majority of children's language learning experiences occur in inclusive early child care and education settings. Few evidence-based professional development (PD) programs exist to empower early childhood education providers to use language instruction practices with children in inclusive classrooms. There is little research on providers'…

In children with a hearing loss who receive cochlear implants (CIs) under the age of 2, regular assessments are conducted to monitor auditory and linguistic progress. However, the collection of authentic, representative, and reliable expressive language data on young children with CIs remains a challenge. The purpose of the study was to determine…

A cluster randomized design was used to investigate the effects of the "Story Friends" vocabulary curriculum on learning of 84 preschoolers in 24 classrooms who were at risk for language difficulties. Children in the treatment condition received explicit vocabulary instruction of 36 words during small-group storybook listening centers…

Teaching vocabularies to young children is critical as vocabulary is related to long-term language, literacy, and academic skills. The current study used a multiple probe design to examine the effects of enhanced milieu teaching with book reading on the use of word approximations in four 2- to 4-year-old females with language delay. The first…

Read It Again! PreK (RIA) is a whole-class, teacher-implemented intervention that embeds explicit language and literacy instruction within the context of shared book reading and has prior evidence of supporting the language and literacy skills of preschool children. We conducted a conceptual replication to test its efficacy when implemented in…

The purpose of this study was to understand vocabulary characteristics in toddlers who are late talkers (LT) as compared with age-matched (AM) and vocabulary-matched (VM) peers. The semantic categories (e.g., animals, foods, toys) and the percentage of nouns, verbs, and closed-class words in the vocabularies of 36 toddlers (12 LT, 12 AM, 12 VM)…

An adapted alternating treatments design, replicated across two books, was used to examine the effects of Dialogic Reading delivered using traditional paperback books and technology-enhanced books utilizing a Surface tablet on the vocabulary acquisition of four preschoolers with autism spectrum disorder. For each book, 30 words were randomly…

This study examined the effects of an adapted alternating treatments design (AATD) consisting of teacher-facilitated and iPad-facilitated instruction on at-risk preschool children's vocabulary. Instruction was provided on 42 verbs, divided equally between treatments, across five participants over the course of 7 weeks. Dependent variables included…

A dialogic storybook-based intervention integrating dialogic storybook reading with early literacy activities is studied with a longitudinal quasi-experimental study design. The effects of this intervention, in addition to a regular early childhood education (ECE) program, on kindergartners' vocabulary and phonological awareness development are…

Access to high-quality education is uneven, particularly for preschool children who are at risk for school failure. Professional development (PD) for teachers, including the use of coaching, is an increasingly common approach for promoting evidence-based instruction. Existing research suggests that the frequency of teacher participation in a PD…

This study compared the effectiveness and efficiency of using a small-group massed-trial instructional format to an individually administered distributed-trial format, both using the constant time delay procedure, in teaching eight preschool children (including three with developmental disabilities) to name pictures. Although all subjects acquired…

Longitudinal data on the unstructured interactions at home of nine children (ages 11-60 months) with Down syndrome were used to compare individual differences in initial expressive vocabulary growth to data on 42 children without disabilities. Findings indicate that the overall pattern of vocabulary growth was similar in all the children.…

This study tested the predictive validity of the Communication Composite of the Communication and Symbolic Behavior Scales with 58 children (ages 17 to 34 months) functioning at the prelinguistic stage of language development. Evaluation of expressive vocabulary 1 year later found that the Communication Composite and all tested clusters were…

Five children (27 to 47 months old) with mild to borderline levels of mental retardation were given a milieu language intervention program of 3 or 4 small group training sessions weekly. Results indicated the training had a clear facilitative effect on the acquisition and generalized use of common nouns and verbs by four of the subjects.…
