We evaluated the long-term effects of a supplemental, small-group kindergarten vocabulary intervention in fall and spring of first grade and winter of second grade. Participants included students from two studies, an initial efficacy study and a subsequent replication study, identified as at risk for language and learning difficulties, who were…

We explored reading comprehension development in children on the spectrum from pre-school to the first (YOS1) and third year of schooling (YOS3). Children were first assessed on meaning-related skills in pre-school. Forty-one children completed follow-up assessments of reading comprehension, reading accuracy, and listening comprehension in YOS1.…

Children from diverse backgrounds are able to learn new words from educational media. However, learning is often partial and fragile, leaving much room for uncovering strategies that can increase the efficacy of educational media in supporting children's vocabulary knowledge. The present study investigated one such strategy--repeated viewing of…

Various studies have shown that bilingual children score lower than their monolingual peers on standardized receptive vocabulary tests. This study investigates if this effect is moderated by language distance. Dutch receptive vocabulary was tested with the Peabody Picture Vocabulary Test (PPVT). The impact of cross-language distance was examined…

Problem/Purpose: Young children with developmental speech and/or language impairment (DSLI) often fail to develop important oral language and early literacy skills that are foundational for subsequent schooling and reading success. The purpose of this investigation was to examine the efficacy of the TELL curriculum and associated evidence-based…

This paper reports results from two studies conducted to examine word learning among preschool children in group book reading while we developed a scalable method of teaching words during book reading. We sought to identify factors that fostered both depth and breadth of learning by varying the type of information children heard about words while…

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…

We investigated whether individual differences in overall receptive vocabulary knowledge measured at the beginning of the year moderated the effects of a kindergarten vocabulary intervention that supplemented classroom vocabulary instruction. We also examined whether moderation would offset the benefits of providing Tier-2 vocabulary intervention…

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…

The Massachusetts Preschool Expansion Grant (PEG) model supported and expanded high-quality preschool in high-needs communities. PEG required shared governance between local school districts and Massachusetts Department of Early Education and Care-licensed community-based programs. The 48 PEG classrooms provided free prekindergarten for…

This study examined the relations between problem behaviors and early learning outcomes among 138 children in dual-language pre-K programs who were identified at the beginning of the school year to be at risk for difficulties in early language and literacy development. Children's expressive and receptive vocabulary, listening comprehension, and…

This study was designed to experimentally examine how supplemental vocabulary instruction provided in either whole-group or small-group settings influences low-income preschoolers' word knowledge and conceptualdevelopment. Using a within-subject design, 108 preschool children from 12 Head Start classrooms participated in an 8-week intervention,…

The purpose of this study was to support teachers' child-directed language and student outcomes by enhancing the educative features of an intervention targeted to vocabulary, conceptual development and comprehension. Using a set of design heuristics (Davis & Krajcik, 2005), our goal was to support teachers' professional development within the…

In 2012-2013, AISD pre-K students demonstrated growth in receptive vocabulary on a nationally-normed test. Students enrolled in multiple programs showed greater growth in receptive vocabulary in their native language than did other pre-K students. [Funding for this report was provided by Title I funds.]
