This article considers the important matter of language availability in the lives of babies and children. Without this language availability, knowing, thinking, and expression cannot blossom and mature. It draws on insights gained during a research study of 5-6-year-old children in low socioeconomic schools, designed to explore the impact of…

We investigated whether individual differences in overall receptive vocabulary knowledge measured at the beginning of the year moderated the effects of a kindergarten vocabulary intervention that supplemented classroom vocabulary instruction. We also examined whether moderation would offset the benefits of providing Tier-2 vocabulary intervention…

Language ability plays a major role in children's future development. In the present study, the effect of three interactive reading approaches on children's language ability was investigated through a pre-posttest design. Participants were N = 73 children (aged 4-6) from three early childhood education classrooms. Classrooms were assigned to one…

A large linguistic distance exists between spoken Arabic and the Modern Standard Arabic (MSA) the literary language (a diglosia). Novice readers, therefore, struggle with the complex orthography of Arabic as well as the mastering of MSA.

The contribution of repeated e-book reading with and without word explanation support and its effect on receptive and expressive word learning among preschoolers was examined. Seventy-eight kindergartners were randomly divided into an experimental and a control group. The experimental group received two individual reading sessions of an e-book…

Combining data from a series of three planned consecutive randomized controlled trials, the present study investigates two literacy interventions for preschool children with autism spectrum disorder. For the first cohort, children were randomized to interactive book reading (IBR; treatment) or business as usual (BAU; control); in Cohort 2,…

In this thesis, I present three related papers that collectively investigate the instructional supports on screen and in the media viewing context that influenced English and heritage language vocabulary knowledge in DLLs. In study 1, I examine how specific pedagogical approaches used in educational media might benefit DLLs. In study 2, I…

We examined the relations between teachers' use of comments during book reading sessions in preschool classrooms and the vocabulary growth of children with low and moderately low language ability. Using data from a larger randomized controlled trial, we analyzed comments defined as utterances that give, explain, expand, or define. Comments were…

An emerging body of research examines language learning of young children from experiences with digital storybooks, but little is known about the ways in which specific components of digital storybooks, including interactive elements, may influence language learning. The purpose of the study was to examine the incidental word learning and story…

This study described the commenting practices of Head Start teachers, and the relationship of comments to the expressive and receptive vocabulary growth of children with below-the-mean language ability across one year of preschool. Participants included 52 Head Start teachers, and 489 children (247 early intervention candidates and 242 Head Start…

This study examined the efficacy of using different types of mobile media apps to increase the receptive and expressive vocabulary development of 3-, 4-, and 5-year-old preschool children living in economically disadvantaged communities. Children and teachers in four Head Start classrooms participated in the quasi-experimental study, which…

Research Findings: This study examines the effects of low- and high-cognitive demand discussion on children's story comprehension and identifies contributions of discussion, initial vocabularies, and parent reading involvement. A total of 70 English learner preschoolers took baseline vocabulary tests in Portuguese and English, were randomly…

This study examined preschool and kindergarten English language learners (ELLs) attending a migrant summer programme and their vocabulary word learning during both adult-read and technology-enhanced repeated readings. In a within-subject design, 24 ELLs (four to six years old) engaged in repeated readings in a control and a treatment condition. In…

This study examined the impact of training mothers to talk elaboratively about the past on children's understanding of mind. The researchers randomly assigned 102 mothers of 19-month-old children to a training or no-training group. Mothers in the experimental group received training in an elaborative style of talking about the past when children…

This study examined the additive benefit of parent dialogic reading techniques in older, high-risk preschool children using multiple baseline design across participants, a single subject research design, as was as well as pre-test and post-test measures. Five preschoolers age-eligible to begin kindergarten the following school year participated.…
