Language learners have unprecedented opportunities for developing second language literacy skills and intercultural understanding by reading authentic texts on the Internet and in multimedia computer-assisted language learning environments. This article presents findings from a meta-analysis of 11 studies of computer-mediated glosses in second…

The large and rapidly expanding body of literature on bilingual acquisition is mostly comprised of either single-case or cross-sectional studies. While these studies have made major contributions to our understanding of bilingual children's language development, they do not allow researchers to compare and contrast results with regard to…

Research examined construct meaning and validity for two new measures of receptive and expressive vocabulary for Spanish-speaking kindergarteners learning English. Substantive validity and generalizability of score meaning was assessed by examining correlations between an established measure (Peabody Picture Vocabulary Test-PPVT) and new measures…

Integrating comprehension and vocabulary instruction in read-alouds can help teachers make the very most of class time. The curriculum described illustrates how read-alouds, when implemented with strategic purpose, can boost learners' vocabulary knowledge and reading comprehension. Specifically, the author presents guidelines for: (1) selecting…

The positive effects of joint book reading (JBR) between parents and children have been widely presumed. However, the impact of JBR has not been widely investigated in toddlers, nor has the extant literature considered the context of JBR reading sessions (e.g., reader, prompt, occasion, who chose the book, etc.). The present study examined the…

Research has documented the large differences in young children's vocabulary knowledge. In light of the strong relationship between vocabulary knowledge and reading comprehension, this gap is particularly worrisome and points to the critical need for well-articulated vocabulary instruction across the grades. The author describes character trait…

This study examined how three different sources of stimulus variability--overall amplitude, fundamental frequency, and speaking rate--affect second language (L2) vocabulary learning. Native English speakers learned Spanish words in presentation formats with no variability, moderate variability, and high variability. Dependent measures were…

Recent research on early word learning suggests that children's behavior when-generalizing novel nouns integrates their prior vocabulary knowledge with the specifics of the task. This study examines how these factors interact on the moment-to-moment time scale of the training children receive and the sequence of stimuli they are shown. In 1…

This preliminary study investigated the potential of using a dynamic approach to assessing expressive word mapping. Because measuring word mapping with productive language responses is much more difficult than measuring receptive word mapping, incorporating a dynamic measure allowed us to tap partial mapping and provided useful information on word…

The authors, one a teacher-researcher and the other a literacy researcher, take on the daunting task of vocabulary instruction in a school with a socioeconomically diverse population. They have designed a literacy program that emphasizes vocabulary development and uses personal choice (for motivation) and scaffolded literacy strategies (for…

Math is not the only topic that will be discussed when young children are asked to care for and count "mealworms," a type of insect larvae (just as caterpillars are the babies of butterflies, these larvae are babies of beetles). The following activity can take place over two months as the beetles undergo metamorphosis from larvae to adults. As the…

A yearlong formative experiment explored the impact of a comprehensive vocabulary instruction program in a diverse, fifth-grade classroom. The classroom teacher and two university collaborators: (1) provided rich language experiences; (2) taught individual words; (3) taught word-learning strategies; and (4) promoted word conscientiousness. Results…

Words associated with perceptually salient, highly imageable concepts are learned earlier in life, more accurately recalled, and more rapidly named than abstract words (R. W. Brown, 1976; Walker & Hulme, 1999). Theories accounting for this concreteness effect have focused exclusively on semantic properties of word referents. A novel possibility is…

Purpose: The purpose of this exploratory study was to examine the variability and predictors of expressive vocabulary development in children with autism and very delayed language. Method: This study involved 35 children with autism whose initial chronological ages were between 20 and 71 months and whose initial expressive vocabularies were less…

This study focused on how to help students translate word problems so that they understand how to solve them, and so they are successful with word problems. I have created three research questions to focus on during this research project. First, how will direct instruction of word meaning help clarify the operation needed, affect the achievement…
