This study examined whether there are processing differences between children with Down syndrome (DS; n = 22; 7 years 8 months to 13 years 10 months) and typically developing children (TD; n = 22; 6 years 6 months to 10 years 10 months), matched for receptive vocabulary. The TD children performed better on tests of nonverbal intelligence…

Children vary widely in the rate at which they acquire words--some start slow and speed up, others start fast and continue at a steady pace. Do early developmental variations of this sort help predict vocabulary skill just prior to kindergarten entry? This longitudinal study starts by examining important predictors (socioeconomic status [SES],…

This study examined the ways in which the language that Head Start teachers used during book reading, as well as the extent to which they made explicit connections between book reading and other instructional activities, were linked to preschoolers' vocabulary development. Participants included 10 Head Start teachers and 153 children in their…

Background: A significant number of pupils in UK schools learn English as an additional language (EAL). Relative differences between the educational attainment of this group and monolingual, English-speaking pupils call for an exploration of the literacy needs of EAL learners. Aims: This study explores the developmental progression of reading and…

This meta-analysis summarizes research on the effects of a comprehensive, interactive web-based software (AXXX) on the development of reading competencies among kindergarteners and elementary students. Findings from seven randomized control trials and quasi-experimental studies undertaken in a variety of contexts across Canada, Australia and Kenya…

The purpose of this correlational study was to determine if variables known upon a group of students' enrollment in kindergarten had a significant relationship with their high-stakes reading assessment results obtained six years later, in the students' fifth grade year. Archival data was gathered from a rural northern Georgia school district.…

This study explores the role that socioeconomic status (SES), home and school language and literacy practices, and oral vocabulary play in the development of English reading skills in Latino English language learners (ELLs) and how these factors contribute differentially to English reading outcomes for children of different ages and in different…

Purpose: The purpose of this study was to determine the effectiveness of a conversation intervention including 500 min of linguistically and cognitively complex talk on the expressive vocabulary growth of prekindergarten children. Method: Children (N = 73) were randomly assigned to control or a 10-week experimental intervention condition. Twice…

A study was conducted in 26 Head Start classrooms with 264 children to compare the effect of a read aloud plus extension activities intervention over a control group to the effect of a read aloud only intervention over a control group on preschool children's vocabulary. Children were assessed before and after the intervention on target vocabulary…

Although pre-K students' average gains on the 2010-2011 Peabody Picture Vocabulary Test (PPVT in English, TVIP in Spanish) significantly differed by vertical team, these differences were attributed more to the students' school or classroom rather than to the vertical team in which a school resided. [For "Prekindergarten Evaluation Series,…

Purpose: This archival study examined the relationship between the speech sound production skill of kindergarten children and literacy outcomes in Grades 1-3 in a data set where most children's vocabulary skills were within normal limits, speech therapy was not provided until 2nd grade, and phonological awareness instruction was discouraged at the…

Classmates' academic skill level (peer effects) is emerging as an important predictor of individual student achievement, particularly in the early grades. However, less is known about the influence of peer effects with regard to classmates' self-regulation skills and whether they are associated with students' academic gains. Examining this is the…

Vocabulary instruction is a critical component of early language and literacy programs. Vocabulary skills in the early elementary school years are strong predictors of later reading achievement and there is a correlation between vocabulary knowledge and reading comprehension. Children who have limited vocabulary in kindergarten are at high risk of…

This study tested if parents taught to use an interactive ("dialogic") reading style to promote early vocabulary skills continued to read this way as their children grew older. Approximately half the 78 participants received instruction in dialogic reading when their child was age 2 or 3 years, the other half had no prior instruction. Parent-child…

Why does the United States lag behind so many other countries on international education assessments? The traditional view targets school-based explanations--U.S. schools attract poorer teachers and lack the proper incentives. But the U.S. educational system may also serve children with comparatively greater academic challenges as a result of…
