We discuss an original study and two replications conducted over 18 years examining the impact of Teacher Study Group (TSG) in Vocabulary, a professional development (PD) approach for improving pedagogy and student learning. Study 1 focused on the design and development of the PD and included a small-scale randomized controlled trial to assess the…

Purpose: This study compares responses of children who are deaf and hard of hearing (DHH) who use spoken language with responses of children who have typical hearing on a repeated word association task to evaluate lexical-semantic organization. Method: This study included 109 participants in early kindergarten or who had completed first grade. The…

This qualitative case study examined the contribution a year-long professional development in the science of reading had on 10 first-grade teachers' knowledge of how reading develops and their instructional practices. Data for this research study was collected through a longitudinal interview process, from pre- and post-knowledge inventory…

Longitudinal models of individual growth typically emphasize between-person predictors of change but ignore how growth may vary "within" persons because each person contributes only one point at each time to the model. In contrast, modeling growth with multi-item assessments allows evaluation of how relative item performance may shift…

Longitudinal models typically emphasize between-person predictors of change but ignore how growth varies "within" persons because each person contributes only one data point at each time. In contrast, modeling growth with multi-item assessments allows evaluation of how relative item performance may shift over time. While traditionally…

Interactive book reading (IBR) as a context for vocabulary learning is studied widely in preschool children and kindergarteners. In the present study, we elaborate on this prior research by investigating the effects of a five-week IBR intervention on first graders' expressive target vocabulary growth. A repeated measures design with two…

Parental education and child gender are related to learning and development during childhood and adolescence. The present study investigated the role of mother's education level and child gender for children's vocabulary and math skills in Norway. Children's vocabulary and math skills were assessed in Early Childhood Education and Care (ECEC)…

Engaging in frequent, meaningful conversation during the early years of schooling is foundational for children's literacy development. Specifically, developing oral language through daily conversations is essential for language comprehension, and eventually, reading comprehension. In this article, we discuss how teachers can use the…

Purpose: Word learning requires the creation of phonological and semantic representations and links in long-term memory. Phonological distance of a given word from the spoken language affects children's lexical-phonological representations and processing. The study investigates the role of the phonological distance of Modern Standard Arabic (StA)…

Dual language learner children (DLLs) benefit from early childhood education (ECE) and learning multiple languages, but research has predominantly focused on English monolingual children, with limited insight on the ECE and early development of DLLs. This study investigated whether DLLs' developmental assets assessed at pre-k entry (i.e. English…

Students most at risk for reading-related disabilities frequently struggle with word recognition and oral language, including, in the earliest grades, specific skills related to phonological awareness and vocabulary. Classroom teachers' delivery of high-quality differentiated supplemental instruction may promote reading acquisition for these…

Although development of young children's vocabulary knowledge is critical for their literacy, it often is neglected in classrooms, especially those pressed for time. In this article we explore a literacy coach's implementation of SAIL (Survey, Analyze, Interpret, Link), an instructional framework that integrates academic vocabulary (AV)…

In this manuscript we show how readalouds can significantly enrich student vocabulary and comprehension by demonstrating enhancements that will foster student learning and language development. We anchor our examples to empirical evidence demonstrating that the content of a readaloud (i.e., the what we teach) as well as the quality of the…

Despite huge investments in interventions designed to support oral language skills in early childhood and beyond, many of the interventions fail to identify impacts on children's language learning. Programmes may have limited impact because they do not sufficiently succeed in supporting teachers' instructional talk, and thus, more efficiently…
