Background: Previous studies have explored the size and word type composition (nouns, predicates, etc.) of expressive vocabularies of preschool children with Down syndrome, both spoken and signed. Separately, overall preferences for modality of expression have also been explored. Aims: To extend previous findings by describing the relationships…

Understanding the factors associated with variation in the implementation of educational programs has emerged as a key research focus, in an effort to identify how promising programs can be scaled up across their targeted contexts. The current study explored demographic-related variation in program dosage using a novel source of implementation…

Research suggests that reading for understanding, especially narrative text, is difficult for children with autism spectrum disorder (ASD); yet research on how to effectively teach skills associated with reading comprehension is limited and has generally deemphasized vocabulary interventions. This single case research design study (i.e., a…

Incidental acquisition of vocabulary has been extensively studied by many researchers through various media, such as employing reading comprehension. However, there is a dearth of studies that focus on the contribution of listening to the incidental acquisition of vocabulary. The current study aims to fill this gap. This study explored the effect…

Students' knowledge of academic vocabulary is a crucial aspect of learning English as a second or foreign language at the university level. Using academic vocabulary lists could be a valuable resource in teaching and learning vocabulary. This study measured the academic vocabulary size of Nepalese university students using Schmitt's (2010)…

What makes a word easy to learn? Early-learned words are frequent and tend to name concrete referents. But words typically do not occur in isolation. Some words are predictable from their contexts; others are less so. Here, we investigate whether predictability relates to when children start producing different words (age of acquisition; AoA). We…

For children to become strong readers, they need to learn a huge number of words--at least 100,000 by the time they get to eighth grade. It is impossible to teach that much vocabulary directly; children gain most of their vocabulary indirectly, as their knowledge of the world expands. This article discusses how much of this learning happens…

Child-directed speech has long been known to influence children's vocabulary learning. However, while we know that caregiver utterances differ from those directed at adults in various ways, little is known about any differences in the lexical properties of child-directed and adult-directed utterances. We compare over half a million word tokens…

Shared book reading is a common and effective way to support vocabulary knowledge. However, it is not the only pedagogy for supporting this learning goal. We propose a "toolbox" of activities that teachers can use to foster vocabulary acquisition in young children. We first discuss the science behind why these activities are effective…

This study aims to determine the effectiveness of implementing a multilayer model in lesson plan (LP) to increase the vocabulary knowledge of deaf students. This study is single-subject research with an A-B-A design (baseline-intervention-maintenance). The intervention instrument used was a LP that consisted of four units, each containing four…

This study examined the effects of spaced practice on second language (L2) vocabulary learning under different learning conditions. One hundred fifty Korean learners of L2 English were divided into five groups: one control (no treatment) and four experimental groups based on learning condition (fill-in-the-blanks vs. flashcards) and spacing type…

The appropriate amount of first language (L1) and second language (L2) to use in L2 learning has been constantly debated (e.g., Cummins, 2007; Hall & Cook, 2012). This study situates the debate of L1 and L2 use in the context of vocabulary learning from reading. By examining the potential moderating factors on the comparison of L1 and L2…

Family literacy programmes can take many shapes, and are often focused on training adult caregivers to engage in particular literacy activities with their young children. In this study, through a series of five, two-hour workshops, we instead worked to help families take advantage of opportunities to infuse literacy learning into their daily…

Young children often make pragmatic assumptions when learning new words. For example, they assume that a speaker who uses different words intends to refer to different things -- the so-called principle of contrast. We used a standard disambiguation task to explore whether children's assumptions about contrast depend on how much words differ.…

This brief and infographic highlights the importance of explicit vocabulary instruction as part of intensifying reading instruction, with a focus on what to teach and how to teach it. Grounded in the science of reading, this resource offers practical guidance to help educators deliver instruction that is clear, accessible, and effective for all…
