The vocabulary size and composition of one group of full-term and three groups of low risk preterm children with different gestational ages (GA) were longitudinally compared at 10, 22 and 30 months of age. Expressive vocabulary development was assessed through the CDI. Cognitive development was also assessed at 22 months (Batelle Developmental…

This paper reports on the curriculum development stage for a larger science-literacy intervention for secondary school newcomers enrolled in an urban US school. After providing background to the study, we review literature on effective vocabulary instruction and report on the "Science Vocabulary Support" program development, refinement,…

Purpose: This study investigates the heritability of language, speech, and nonverbal cognitive development of twins at 4 and 6 years of age. Possible confounding effects of twinning and zygosity, evident at 2 years, were investigated among other possible predictors of outcomes. Method: The population-based twin sample included 627 twin pairs and 1…

We systematically assessed the relationships between growth of four components of verbal ability--Information, Similarities, Vocabulary, and Comprehension subtests of the Wechsler Intelligence Scale-Revised--and longitudinal growth from Grades 1 to 9 of the Woodcock-Johnson Psycho-Educational Battery Passage Comprehension subtest while controlling…

Children develop linguistic competencies during interactions with more knowledgeable others. Consequently, one way to support this development is by enhancing the home literacy environment (HLE) in which children live. In this study a non-intensive intervention procedure was developed to improve HLE and linguistic competencies of 125 German…

Research Findings: This study reports initial descriptive and validity results of a new early childhood classroom observation measure, the Classroom Language Environment Observation Scales (CLEOS), designed to capture teachers' use of both implicit language supports (e.g., incidental scaffolding and shared reading) and more explicit language…

This work explores whether the facilitative effect of causal information on preschoolers' word and descriptive fact learning persists in school-age children. Twenty-three 5-year-olds just beginning school and 23 6- to 7-year-olds who had accumulated over a year of schooling were taught novel words along with descriptions of causally rich,…

This cross-linguistic study investigated whether the native language has any influence on lexical composition among Italian (N = 125) and Finnish (N = 116) very preterm (born at <32 gestational weeks) children at 24 months (controls: 125 Italian and 146 Finnish full-term children). The investigation also covered the effect of maternal education…

Although the relationship between sound and meaning in language is assumed to be largely arbitrary, reliable correspondences between sound and meaning in natural language appear to facilitate word learning. Using a set of independently normed pseudoword and shape stimuli, we examined the real-time effects of sound-to-shape correspondences at…

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)…

This study presents the results of a meta-analytic study about the effects of digital game-based learning (DGBL) on vocabulary. The results of the study showed that the effects of DGBL on vocabulary learning may vary with game design features (Q = 5.857, df = 1, p = 0.016), but not with learners' age (Q = 0.906, df = 1, p = 0.341) or linguistic…

A word learning paradigm was used to teach children novel words that varied in phonotactic probability and neighborhood density. The effects of frequency and density on speech production were examined when phonetic forms were nonreferential (i.e., when no referent was attached) and when phonetic forms were referential (i.e., when a referent was…

Both literacy and career technical education are believed to be linked to better outcomes for juvenile offenders transitioning back to their communities after release. Therefore, this study employed a single group, pretest-posttest design to investigate the extent to which 13 juvenile offenders improved their understanding and completion of…

This article focuses on the design of digital instructional game (DIG) tasks for young second language (L2) learners. The aim of the study is to identify motivational task elements based on what children respond to positively in games and incorporate into their own L2 vocabulary learning game designs. Eighty-two sixth-grade students (ages 11-12…

Understanding mathematics is an essential part of everyday life and can range from simple tasks such as using basic math skills to more complex tasks. Success in mathematics is a requirement for success in today's modern world. A gap in developing mathematical skills can create complications and interfere with job opportunities. Another basic…
