Purpose: This study examined the effect of Vocabulary Acquisition and Usage for Late Talkers (VAULT) treatment on toddlers' expressive vocabulary and phonology. Parent acceptability of VAULT treatment was also considered. Method: We used a nonconcurrent multiple baseline single case experimental design with three late talking toddlers aged 21-25…

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 investigates the degree to which children anthropomorphize a robot tutor and whether this anthropomorphism relates to their vocabulary learning in a second-language (L2) tutoring intervention. With this aim, an anthropomorphism questionnaire was administered to 5-year-old children (N = 104) twice: prior to and following a seven-session…

Time has contributed to most of our daily activities. In the field of understanding how the human brain reacted to specific learning processes, the neuroscientist supports the impact of having multiple learning sessions with the retention of knowledge. Spaced Learning is a product makes out of human's lack of capacity in retaining information and…

Background: Learner performance in literacy in the primary education sector is in a state of crisis in South Africa. Whilst many more learners have physical access to education post-1994, the quality of education remains polarised along socio-economic lines. This article sets out to engage with current literature on literacy interventions…

Purpose: Prior studies report conflicting descriptions of the relationships between phonological awareness (PA), vocabulary, and speech perception in preschoolers with speech disorders. This study sought to determine the nature of these relationships in a sample of school-aged children with residual speech sound errors affecting /[voiced alveolar…

This meta-analysis examines the effectiveness of technology-assisted second language (L2) vocabulary learning as well as identifies factors that may play a role in their effectiveness. We found 34 studies with 2,511 participants yielding 49 separate effect sizes. Following the procedure developed by Hunter and Schmidt (2004), we corrected for…

For the first time, this study investigated whether children with autism spectrum disorder (ASD) and typically developing (TD) children matched on language comprehension (M age equivalent = ~ 44 months) are more likely to retain words when learning from colour photographs than black-and-white cartoons. Participants used mutual exclusivity to fast…

"The limits of my language are the limits of my mind. All I know is what I have words for" (Wittgenstein). When learning something completely new, we connect the unknown term to an already existing part of our knowledge. We can only build new ideas and insights upon an existing conceptual foundation. In the field of statistics, we…

Recently there has been some debate about the appropriacy of different lexical units in pedagogy and research (e.g., Brown et al., 2020; Dang & Webb, 2016a; Kremmel, 2016; Laufer & Cobb, 2020; McLean, 2018; Nation, 2016; Nation & Webb, 2011; Vilkaite-Lozdiene & Schmitt, 2020). The lexical unit (word types, lemmas, flemmas, word…

Purpose: The purpose of this study was to determine if a direct, explicit method of teaching vocabulary with the Vocabulary Scenario Technique -- General Education 16 Encounter (VSTGE16) protocol would yield gains in the vocabulary knowledge of fourth grade students in a general education classroom. Two research questions examined whether fourth…

Shared reading is an important context for the development of communication, language, and literacy skills in young children. Research conducted with children who require augmentative and alternative communication has indicated that dialogic reading techniques utilized in shared reading can aid in the development of communication skills. One area…

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…

Background: Vocabulary and domain knowledge are important factors that influence comprehension development. However, these factors have most frequently been examined in relation to reading comprehension and much less frequently examined in relation to listening comprehension. Moreover, almost no empirical studies have examined profiles of…
