Besides explicit inference of word meanings, associating words with diverse contexts may be a key mechanism underlying vocabulary learning through reading. Drawing from distributional semantic theory, we developed a text modification method called reflash to facilitate both word-context association and explicit inference. Using a set of left and…

This study set out to investigate the relationship between L2 vocabulary knowledge (VK) and second-language (L2) reading/listening comprehension. More than 100 individual studies were included in this meta-analysis, which generated 276 effect sizes from a sample of almost 21,000 learners. The current meta-analysis had several major findings.…

In this article, the literature on instruction in morphological analysis strategies with English Language Learners (ELLs) is reviewed to identify vocabulary outcomes for these students. The nature of instruction and quality of outcomes are examined for ELLs in general, and also for those with or at risk of reading disabilities. A total of nine…

Decades of research have identified features of classrooms and teachers' talk that are associated with children's language growth. Unfortunately, much of this work has not yet translated to widespread practice in early childhood classrooms. Given the important contributions that early language development makes to later academic achievement,…

Selectively reviews influences on young children's word learning. Analyzes difficulties with the "constraint" concept in examining word learning. Concludes that the effect of so-called constraints cannot be separated from a wide range of cognitive and contextual influences on children's inferences about novel word meanings. Offers…

This paper surveys some current developments in second language vocabulary assessment, with particular attention to the ways in which computer corpora can provide better quality information about the frequency of words and how they are used in specific contexts. The relative merits of different word lists are discussed, including the Academic Word…

In this manuscript, the author explores the question, What does research suggest for middle level readers? To answer it, she conducts a synthesis of empirical studies published between 1990 and 2001 that appeared in journals linked to the author's professional membership (i.e., "Research in Middle Level Education" ("RMLE"), "Reading Research…

This article focuses on development, elaboration, and measurement of word repertoire from world knowledge, as well as factors affecting the word-learning process and vocabulary assessment and remediation methods such as definition and association tasks. Several alternatives for vocabulary expansion based on world knowledge principles are also…

This article relates the ability to understand individual sentences both in and out of context by normal and developmentally delayed children at various developmental stages to the concept of world knowledge. Implications for assessment and treatment of sentence comprehension deficits among language-disordered students are discussed. (PB)
