This study investigated the feasibility of a vocabulary-based teacher intervention to increase preschool teachers' production of complement clauses (e.g. "I wonder if we can put the monkey in the tree") in teacher-children play interactions. Using a multiple baseline across participants design we measured the impact of an intervention…

Current research on cross-language transfer has focused primarily on literacy development. The present study extends the scope of existing research by focusing on argumentative reasoning, an important but under-research academic skill. A single-case study with a reversal design was conducted with four Chinese-English elementary students with the…

Child-directed speech (CDS), which can help children learn new words, has been rigorously studied among infants and parents in home settings. Yet, far less is known about the CDS that teachers use in classrooms with toddlers and children's responses, an important question because many toddlers, particularly in high-need communities, attend…

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…

This manuscript reports on a corpus-based comparison of native and nonnative graduate students' language production in an asynchronous learning environment. Using 486 discussion board postings from a five-year period (2009-2013), we analyzed the extent to which native and nonnative university students' writing differed in 10 measures of syntactic…

Despite substantial correlational evidence of a relationship between morphological awareness and reading ability, there has been only limited intervention research conducted to document the effects of morphological awareness on various literacy outcomes, particularly reading comprehension, and almost no research comparing the relative…
