Two-year, play-based, full-day kindergarten (FDK) has been shown to have long-term academic and self-regulation benefits for young children. This article addresses the question of whether FDK has particular benefits for children who may be at risk for placement in special education. Participants included 592 kindergarten children in their second…

An adapted alternating treatments design was used to compare the expressive use of thematic vocabulary by three preschool children with developmental delays during Dialogic Reading, a shared book reading intervention, and Activity-Based Intervention, a naturalistic play-based teaching method. The design was replicated across two early childhood…

Almost nothing is known about the capacity of minimally verbal students with autism to develop literacy skills.

We report two studies that examine the effects of play-related variables: length of free play, type of language instructional approach, degree of structure of free play, and amount of teacher involvement in communication with peers. For each study, we target three dependent variables: rate of…

This study examined the effects of an intensive shared book-reading intervention on the vocabulary development of preschool children who were at risk for vocabulary delay. The participants were 125 children, who the researchers stratified by classroom and randomly assigned to one of two shared book-reading conditions (i.e., the experimental, Words…
