Aural vocabulary knowledge (AVK) of high-frequency words is critical for second language listening comprehension. However, learners of English as a foreign language (EFL), despite considerable periods of language study, often do not have the AVK needed for basic communicative competence. A mixed methods approach is applied to determine whether…

Teaching vocabularies to young children is critical as vocabulary is related to long-term language, literacy, and academic skills. The current study used a multiple probe design to examine the effects of enhanced milieu teaching with book reading on the use of word approximations in four 2- to 4-year-old females with language delay. The first…

Purpose: Identifying appropriate targets for vocabulary instruction and determining the optimal sequence for instruction continue to be a challenge. The purpose of this study is to investigate how previously studied lexical characteristics collectively influence children's word learning. Method: A secondary data analysis was conducted using the…

Longstanding gaps between the reading achievement of English learner (EL) students and native English speakers highlight the need for evidence-based reading interventions validated for EL students. This study compared the efficacy of two flashcard-based interventions, incremental rehearsal (IR) and strategic incremental rehearsal (SIR), for…

Purpose: Identifying appropriate targets for vocabulary instruction and determining the optimal sequence for instruction continue to be a challenge. The purpose of this study is to investigate how previously studied lexical characteristics collectively influence children's word learning. Method: A secondary data analysis was conducted using the…

Purpose: This study reexamines the claim that difficulty forming memories of words comprising uncommon sound sequences (i.e., low phonological neighborhood density words) is a determinant of delayed expressive vocabulary development (e.g., Stokes, 2014). Method: We modeled communicative development inventory data from (N = 442) 18-month-old…

Child-directed speech (CDS), which can help children learn new words, has been rigorously studied among infants and parents in home settings. Yet, far less is known about the CDS that teachers use in classrooms with toddlers and children's responses, an important question because many toddlers, particularly in high-need communities, attend…

Purpose: The goal was to determine whether interactive book reading outcomes for children with developmental language disorder (DLD) were affected by manipulation of dose (i.e., the number of exposures to the target word during a book reading session) and dose frequency (i.e., the number of repeated book reading sessions) and whether pretreatment…

In the field of second language acquisition (SLA), a large base of research has shown the great influence of L2 reading on L2 vocabulary acquisition. Nevertheless, researchers have also found that acquiring new vocabulary happens rather gradually and in small amounts. Without altering the incidental nature of vocabulary acquisition through…

We investigate the impact of a relatively brief cross-curricular intervention, Word Generation, on middle school students' development of taught academic vocabulary. Students (n = 8382) in forty-four middle schools in three urban districts were randomly assigned to treatment or control conditions. Treatment teachers implemented the program with…

Intervention exercises have tended to be limited to restricted controlled output in studies related to second language (L2) learners' acquisition of written academic formulaic sequences (FSs), while measurement of use has been drawn from freer output (AlHassan & Wood, 2015; Jones & Haywood, 2004; Peters & Pauwels, 2015). The current…

This research sought to determine the level of productive vocabulary knowledge of the students grouped according to type of school and curriculum year level; performance of the students in the vocabulary test categorized according to frequency levels; their breadth of productive vocabulary knowledge related to type of school enrolled in,…

Understanding academic vocabulary is essential to student success in school. Use of academic vocabulary words in writing is considered one of the strongest measures of how well a reader understands a given word. In theory, willingness to use academic vocabulary in writing indicates the complexity of acquiring representations of the word's…

This paper reports on task interaction, task success and word learning among second language (L2) learners of different levels of word recognition from speech (WRS) proficiency who used a CALL application previously shown to be effective in the development of L2 WRS. Participants (N = 65) were categorised into three levels of L2 WRS proficiency…

Learning to read requires knowledge of word meanings for those words most commonly encountered in basic reading materials. Many young students lack the basic vocabulary knowledge needed to facilitate learning to read. Two randomized studies were conducted to test the effects of an online, computer-adaptive vocabulary instruction program designed…
