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 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…

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…

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)…

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…

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…

While there is a strong research base that supports intervening early in mathematics, research investigating the importance of mathematics vocabulary is still emerging. Practitioners and researchers may benefit from understanding how mathematics interventions support mathematics vocabulary acquisition, particularly for students who struggle with…

The current quantitative study, a naturalistic field experiment, was conducted in a public primary school in Soweto, Johannesburg, with the objective to examine how children's achievement on four assessments at the beginning of Grade R, namely their numeracy, their mathematics-specific vocabulary, their executive functions, and their logical…

Children with developmental language disorder (DLD) served as a test case for determining the role of extant vocabulary knowledge, endogenous attention, and phonological working memory abilities in cross-situational word learning. First-graders (M[subscript age] = 7 years; 3 months), 44 with typical development (TD) and 28 with DLD, completed a…
