A proposed avenue for increasing students' vocabulary knowledge and reading comprehension is instruction that promotes students' enthusiasm and attention to words, referred to as "word consciousness". This study seeks to investigate, at the utterance level, whether and how word consciousness talk is used in classrooms with young word…

Concept of word--the awareness of how words differ from nonwords or other linguistic properties--is important to learning to read Chinese because words in Chinese texts are not separated by space, and most characters can be productively compounded with other characters to form new words. The current study examined the effects of reader, word, and…

Research to increase the early vocabulary development of urban students has emphasized the central role of teachers and the ways in which teachers use intervention curricula and strategies in their classroom contexts. This study explores teachers' fidelity to different components of a vocabulary intervention, specifically their use of prescribed…

Purpose: Individual differences in vocabulary development may affect academic or social opportunities. It has been proposed that individual differences in word reading could affect the rate of vocabulary growth, mediated by the amount of reading experience, a process referred to as a "Matthew effect" (Stanovich, 1986). Method: In the…

This study compared the effects of 2 strategy-based comprehension treatments intended to promote vocabulary and content knowledge for elementary students at risk for developing reading difficulties (N = 105) with a traditional content approach. The study examined the effectiveness of strategy versus nonstrategy instruction on reading…

The unique relation of language use (i.e., output) to language growth was investigated for forty-seven 30-month-old Spanish-English bilingual children (27 girls, 20 boys) whose choices of which language to speak resulted in their levels of English output differing from their levels of English input. English expressive vocabularies and receptive…

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…

Preschool children begin to represent spoken language in print long before receiving formal instruction in spelling and writing. The current study sought to identify the component skills that contribute to preschool children's ability to begin to spell words and write their name. Ninety-five preschool children (mean age = 57 months) completed a…

We investigate the impact of a relatively brief cross-curricular intervention, Word Generation, on middle school students' development of taught academic vocabulary. Students (n = 8382) in forty-four middle schools in three urban districts were randomly assigned to treatment or control conditions. Treatment teachers implemented the program with…

We investigated the influence of nonparental caregivers, such as foreign domestic helpers (FDH), on the home language spoken to the child and its implications for vocabulary and word reading development in Cantonese- and English-speaking bilingual children. Using data collected from ages 5 to 9, we analyzed Chinese vocabulary, Chinese character…

Research Findings: Mental state verbs (MSV), a component of literate and academic language, may facilitate vocabulary growth, as they relate to metacognitive and metalinguistic awareness as well as decontextualized talk, all of which have been associated with vocabulary growth. In this study, we examined teacher MSV use in group content…

The purpose of this preliminary study was to determine whether incorporating vocabulary instruction in individual reading fluency interventions for English Language Learners (ELLs) would improve reading comprehension. Two vocabulary instructional procedures were contrasted with a fluency-building only condition in an alternating-treatments design…

Research Findings: This study examines lexical- and sentence-level dimensions of academic language to describe teachers' natural use of academic language and its association with vocabulary growth in 489 at-risk 4-year-olds enrolled in Head Start preschool classrooms. Using transcripts derived from video recordings of book-reading sessions in 52…

The purpose of this replication study was to examine the impact of the Teacher Study Group (TSG) professional development in vocabulary on first-grade teachers' knowledge of vocabulary instruction and observed teaching practice, and on students' vocabulary knowledge. Sixty-two schools from 16 districts in four states were randomly assigned to…

Purpose: The current study used an intervention design to test the hypothesis that parent input sentences with diverse lexical noun phrase (NP) subjects would accelerate growth in children's sentence diversity. Method: Child growth in third person sentence diversity was modeled from 21-30 months (n = 38) in conversational language samples obtained…
