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…

This study examined the extent to which classroom quality (emotional and instructional climate) moderates the associations between teachers' beliefs about children, self-efficacy, and children's early language gains (receptive and expressive vocabulary). The study employed multilevel modeling with 606 preschool teachers and 2,536 preschool…

This study compared simultaneous prompting with an error correction procedure for teaching three children diagnosed with autism spectrum disorder expressive labels. Using a parallel treatment design nested within a multiple probe design, the researchers taught each participant how to expressively label pictures of sports teams or cartoon…

Research Findings: A social validity measure was used to examine 56 bilingual preschool teachers' perceptions and acceptability of an interactive shared book reading vocabulary intervention implemented in English with Spanish-speaking preschool children (N = 334) in a dual language program model. Social validity outcomes indicated that bilingual…

Purpose: Previous research has demonstrated that typically developing children, verbal children with a diagnosis of autism, children with Down syndrome, children with developmental language disorder, and children with dyslexia can all benefit from orthographic support during word learning tasks. This study sought to determine if minimally speaking…

Preschool teachers from a high-poverty, urban school district were trained to implement Story Talk, a book reading intervention designed to increase children's vocabulary and language development using supportive materials and strategic individualized coaching. Thirty-five teachers were randomly assigned by site to the intervention (20) or the…

Preschoolers can learn vocabulary from educational videos, but children from low-income backgrounds often do not learn as effectively as their higher income peers. We investigated whether adding attention-directing cues to media (Study 1) and slowing the pacing of media (Study 2) supported vocabulary learning for preschoolers from low-income…

Language ability plays a major role in children's future development. In the present study, the effect of three interactive reading approaches on children's language ability was investigated through a pre-posttest design. Participants were N = 73 children (aged 4-6) from three early childhood education classrooms. Classrooms were assigned to one…

Vocabulary knowledge is essential for successful language learning. However, little is known about young learners' vocabulary learning in a Thai EFL context and the teaching methods that facilitate vocabulary learning. The current study examined whether songs and total physical response (TPR) can facilitate preschoolers' vocabulary acquisition in…

The purpose of this study is to examine the bidirectional relationship between children's language development and challenging behaviors as well as the moderating roles of gender and race/ethnicity. We conducted a number of structural equation modeling analyses with a national representative sample (N = 2,462) of Head Start children from the 2014…

This paper attempts to investigate the repetition of Relative Clauses (RCs) in Mandarin children with Developmental Language Disorder (DLD) (aged 4; 5 to 6; 0) and their typically developing (TD) peers. The results of a sentence repetition task indicate that Mandarin children with DLD perform significantly worse than both groups of TD children,…

This study was designed to examine the effects of coviewing on low-income children's attention to and understanding of novel words in educational media. In addition, we sought to understand coviewing's contribution to children's receptive and expressive word learning when some target words were repeated more or less frequently. Using a…

In this study we examine the effectiveness of a technology-based vocabulary intervention compared to an extended vocabulary intervention that has been validated in previous studies. At-risk first grade students learned new words through each condition in a within-subjects design. Comparisons of target word knowledge between the two conditions were…

We examined the relations between teachers' use of comments during book reading sessions in preschool classrooms and the vocabulary growth of children with low and moderately low language ability. Using data from a larger randomized controlled trial, we analyzed comments defined as utterances that give, explain, expand, or define. Comments were…

Purpose: The purpose of this study was to examine the relationship between executive functioning and word learning among preschoolers with and without developmental language disorder (DLD). Method: Forty-one preschool-age children with DLD were matched to typically developing children on age and sex. Participants were exposed to 10 novel…
