Programs that engage young children in movement and song to help them learn are popular but experimental evidence on their impact is sparse. We use an RCT to evaluate the effectiveness of Big Word Club (BWC), a classroom program that uses music and dance videos for 3-5 minutes per day to increase vocabulary. We conducted a field experiment with…

The aim of the present study was to compare the impact of two different didactic techniques, blended teaching and teaching by the exclusive use of ICT, on preschool children's vocabulary development. Additional aim of the present study was to investigate whether the impact of the two didactic techniques is differentiated by several language and…

Purpose: This study examined the improvement in vocabulary and listening skills of children with ASD through adapted shared reading. It also investigated the generalisation effect of this increase to new books and social validity. Methods: A multiple probe across participants design was used to investigate the effect of ASR (adapted shared…

Vocabulary plays a critical role in later reading achievement of emergent bilingual children (EBC) who are learning two languages. Given emerging vocabulary intervention research for EBC, we synthesize studies on vocabulary interventions designed for preschool and kindergarten EBC to provide the cumulative knowledge on the following dimensions:…

Background and aims: This study was conducted in a clinical setting with the aim of replicating previously used procedures for teaching receptive vocabulary. Researchers increased the number of vocabulary words and maintained use of match-to-sample (MtS), prompting, and reinforcement procedures. Researchers were also interested in the efficacy of…

The use of shared book reading is regarded as valuable to support young children to build their oral language and emergent literacy skills in preschool classrooms. Quantitative and qualitative features of early childhood teachers' (ECTs') shared book reading practices are important contributors to quality shared book reading experiences. The aim…

Purpose: The aims of this study were to explore expressive vocabulary growth rates of children who are deaf or hard of hearing (DHH) during critical periods of brain development (birth to 3 years) as well as the factors that influence the trajectories of vocabulary growth in these early years of development. Of primary interest was the effect of…

Parent-child interactive shared reading can benefit young children's language and emergent literacy skills; however, studies of programs to enhance shared reading often do not evaluate lasting effects after the transition to primary school. In this randomized control study, 69 parents of 3.5-4.5-year-old children participated in one of three…

A cluster randomized design was used to investigate the effects of the "Story Friends" vocabulary curriculum on learning of 84 preschoolers in 24 classrooms who were at risk for language difficulties. Children in the treatment condition received explicit vocabulary instruction of 36 words during small-group storybook listening centers…

The goal of this study was to evaluate immediate and delayed effects of a caregiver-implemented picture book intervention to support children's mathematical language and numeracy skills. Eighty-four 3- to 5-year-olds (M[subscript age] = 4.14) were randomly assigned to intervention (n = 40) or active control (n = 44) conditions. Participants in the…

This study examines the effectiveness of scaling up a vocabulary intervention, pre-K-first grade, using a structured adaptation of the World of Words that allowed teachers some autonomy over its implementation. The purpose was to determine whether such an adaptation could maintain fidelity and promote positive child outcomes. Classrooms (pre-K…

This paper reports on findings from a doctoral study that explored the efficacy of a home-based literacy intervention in advancing preschool children's foundational literacy skills. Two key cognitive skills critical for early literacy success were examined in particular, those being phonological awareness, and elements of oral language, including…

This study examined the effects of practice-based coaching with scripted supports designed to support paraeducators and speech-language pathology assistants (SLP-As) as they implement evidence-based shared book reading strategies with preschoolers with language delays. A single-case, multiple baseline across behaviors was employed. Five U.S.…

A cluster randomized design was used to investigate effects of the Story Friends vocabulary curriculum on learning of 84 preschoolers in 24 classrooms who were at risk for language difficulties. Children in the treatment condition received explicit vocabulary instruction of 36 words during small-group storybook listening centers with extended…

Objective: Two agendas guided this study. The first is to report on a dynamic intervention programme that utilizes key developmental domains and strategies, such as emotional expression opportunities, motor activity, learning in groups, playful learning, and shared reading. The second is to explore the possibility that dynamic intervention can…
