This study applied multilevel modeling to examine the relationship between the percentage of children with mild/moderate disabilities in classrooms and children's language and literacy achievement over an academic year. The sample included 516 preschool children (mean age = 52.3 months, SD = 6.3) in 75 classrooms; 42% of the children had…

Globally, there is great interest in enhancing young children's literacy development as a route to improving worldwide literacy. To contribute to this area of interest, this paper reports findings from a multi-pronged early-literacy program designed to improve the print-knowledge of young children in Yucatec Mayan villages. The school-based…

This study serves as an initial inquiry regarding the early print knowledge of emergent bilingual preschool-age children living in an Indigenous community in Mexico. In this research, we examine various dimensions of print knowledge with Yucatec Maya-Spanish bilingual children for whom one of their languages (Yucatec Maya) is seldom seen in print…

The purpose of this study was to examine the impacts of print-focused read-alouds, implemented by early childhood special education (ECSE) teachers alone or in conjunction with caregivers, on the print knowledge of children with language impairment (LI). Using random assignment to conditions, children with LI were exposed, over an academic year of…

Purpose: Letter knowledge is a key aspect of children's language development, yet relatively little research has aimed to understand the nature of lowercase letter knowledge. We considered 4 hypotheses about children's lowercase letter knowledge simultaneously--uppercase familiarity, uppercase-lowercase similarity, own-name advantage, and…

Preschool children (N=38) from low-income households enrolled in Head Start were evaluated for written language awareness. Analysis indicated significant gaps in print, word, graphic, and metalinguistic awareness. Lowest performance was found in children's ability to identify contextualized print within illustrations and their understanding of the…

This study tested four complementary hypotheses to characterize intrinsic and extrinsic influences on the order with which preschool children learn the names of individual alphabet letters. The hypotheses included: (a) "own-name advantage," which states that children learn those letters earlier which occur in their own names, (b) the…
