A repeated acquisition (RA) design was used to compare the effectiveness of research-based instruction embedded in repeated storybook reading facilitated by an adult or tablet application (app) on the vocabulary knowledge of six preschool children. All participants selected scored below the 40th percentile on the "Preschool Language…

This study contrasted face-to-face and remote coaching models using an empirically-based professional development model, The Early Education model (TEEM). Child care teachers (n = 174) were randomly assigned to 1 of 3 conditions: remote coaching (n = 59), face-to-face coaching (n = 66), and business-as-usual (n = 49). This study examined…

We examined how educating paraprofessionals in preschool classrooms on dialogic reading (DR) affected their storybook reading and effects on children's single word vocabulary. Through a single-case multiple-probe across participants design including four paraprofessionals and eight preschool children, we identified a functional relation between…

The purpose of this study was to explore the use of code-switching in the narratives of dual-language Latino preschoolers, specifically by examining its incidence, types, functions, and grammaticality. Previous work has investigated code-switching in younger children and in older children and adults, but relatively little work has investigated…

Although extensive research exists on vocabulary instruction during book reading in preschool classroom, comparatively little research has been conducted on vocabulary exposure in classroom play contexts and child vocabulary outcomes. The purpose of this study was to examine Head Start teacher and child vocabulary use in dyadic play sessions and…

This study examines the impact of repeated exposures on word learning of preschool children with and without hearing loss (HL) in quiet and noise conditions. Participants were 19 children with HL and 17 peers with normal hearing (NH). Children were introduced to 16 words: 8 in quiet and 8 in noise conditions. Production and identification scores…

We conducted a randomized controlled potential efficacy trial to examine effects of two variants of the Tools for Teachers (TfT) professional development (PD) intervention on preschool teachers' implementation of embedded instruction practices and children's developmental and learning outcomes. Thirty-six preschool teachers recruited from three…

The purpose of this study was to develop an intervention for 2-year-old children to enhance play and language skills. The intervention was implemented over a 4-week period and included components of reading, modeling, and positive reinforcement of language and play. Specifically, children were read a story and played with a matching toy set.…

The current study evaluated the play behaviors of children with disabilities (e.g., developmental delays, specific language impairment) who participated in a social communication intervention targeting skills such as initiations, responses, name use, proximity, and turn-taking. Three children who were enrolled in an inclusive classroom met the…

Pivotal Response Training (PRT) is a naturalistic, behavioral intervention with a strong evidence-base that is designed to increase generalization and maintenance of responding in children with ASD. Although special education teachers report using PRT, little research to date has examined PRT use in the context of community school programs. There…

The study examined in this review analyzed whether a full two-year "Learning Experiences and Alternative Program for Preschoolers and Their Parents" ("LEAP") training and support model for teachers was superior in improving outcomes of preschool children with Autism Spectrum Disorder (ASD), as compared to a limited…

The purpose of the current study was to evaluate the turn-taking skills of children with and without disabilities who participated in a social communication intervention targeting peer-directed initiations and responses. Eight children met the selection criteria for inclusion in the study. A multiple baseline design across participants (dyads) was…

The purpose of this study was to assess changes in children's language skills and parenting stress following participation in the Parent-Child Mother Goose Program (PCMGP). The intervention group consisted of 29 parents (age range 24 to 43 years, "M" = 33.5, SD = 4.1) and 30 children (18 females and 12 males) with ages ranging from 1 to…

The purpose of this study was to investigate the effects of peer intervention on the social interactions of children with autism spectrum disorder (ASD). In this model, a speech-language pathologist and three early childhood educators trained typically developing peers to engage children with ASD in play. Three preschool children with ASD and six…
