Both early childhood maternal language input and the quality of classroom instruction in elementary school have been shown to be important environmental supports in predicting children's literacy skill development. However, no studies have simultaneously examined these two environmental supports in relation to children's early language skills and…

The association between early language performance and later language and literacy outcomes warrants investigation of strategies teachers can use to maximize children's oral language development during early childhood. Despite a consensus that a language-rich environment is desirable for CHL, there is a limited body of research investigating…

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…

Little analytical scrutiny has been devoted to teacher accommodation of academic language at the early childhood level, despite being a critical school-level factor to consider when addressing at-risk learners' academic needs. The present study investigates how fifteen Head Start teachers support three components of academic language during…

First language learners acquire vocabulary in the context of participation in discourse, and the quantity and richness of that discourse is the best predictor of their progress. Similarly, we argue, engagement in discourse, in particular debate and discussion, is an effective component of classroom instruction for second and foreign language…

This study investigated the long-term effects of structural priming on children's use of indirect speech clauses in a narrative context. Forty-two monolingual English-speaking 5-year-olds in two primary classrooms took part in a story-retelling task including reported speech. Testing took place in three individual sessions (pre-test, post-test 1,…

This study investigated the relation between teachers' (N = 22) use of sophisticated and complex language in urban middle-school classrooms and their students' (mean age at pretest = 11.51 years; N = 782; 568 language minority and 247 English only) vocabulary knowledge. Using videotaped classroom observations, teachers' speech was transcribed and…

This action research study explores explicit vocabulary instruction in an L2 (English) content-area course with a group of university student teachers. The study reviews several positions on the treatment of vocabulary in L2 contexts. The researcher takes up the teaching of explicit vocabulary through class activities and the students' completion…

Two studies investigated the effects of modified interaction on comprehension and vocabulary acquisition among Japanese high school students learning English as a Second Language. The studies found that interactionally modified input resulted in better comprehension and the acquisition of more new words than premodified input. (MDM)
