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…

Instructional design is an integral part of a balanced approach to teaching vocabulary instruction. This article presents several instructional procedures using research-based vocabulary strategies and explains how to design and adapt those strategies in order to reach desired learning outcomes. Emphasis is placed on research-based principles that…

This study examined and compared patterns of errors in the oral definitions of newly learned words. Fifteen 9- to 11-year-old children with language learning disability (LLD) and 15 typically developing age-matched peers inferred the meanings of 20 nonsense words from four novel reading passages. After reading, children provided oral definitions…

This article makes use of Perfetti's Lexical Quality Hypothesis as a perspective for thinking about vocabulary instruction in terms of semantics (meaning), phonology (pronunciation), orthography (spelling), morphology (meaningful word parts), and syntax (how words function in sentences). Examples are presented of how these aspects of vocabulary…

The main point of our study was to examine the vocabulary knowledge of pupils in grades 3-6, and in particular the relative reading vocabulary disadvantage of hearing-impaired pupils. The achievements of 394 pupils with normal hearing and 106 pupils with a hearing impairment were examined on two vocabulary assessment tasks: a lexical decision task…

The current study uses a crossed random-effects item response model to simultaneously examine both reader and word characteristics and interactions between them that predict the reading of 39 morphologically complex words for 221 middle school students. Results suggest that a reader's ability to read a root word (e.g., "isolate") predicts that…

Research has shown that the use of pre-reading activities, such as graphic or advance organizers can positively affect student acquisition of vocabulary and meaning when reading new concepts presented in text. One particularly effective strategy, semantic mapping, can significantly impact students who previously had a lack of prior knowledge on…
