Background: Prominent theories of reading make the prediction that individual differences in children's word learning capacity determine the pace of their acquisition of reading skill. Despite the developmental nature of some of these theories, most empirical research to date has explored the relation between word learning capacity and reading at…

Purpose: Converging evidence demonstrates that robust academic vocabulary and morphology instruction improves literacy outcomes of multilingual adolescents. However, few interventions have focused on teaching word analysis using bound Latin roots, the major meaning-carrying constituents of academic words (e.g. voc meaning "speak" in…

Background: Word-to-text integration (WTI) can be challenging for second-language (L2) learners, although it can positively contribute to reading comprehension. The present study examined the role of WTI, after controlling for decoding, vocabulary and morphosyntactic awareness, in predicting English as an L2 reading comprehension development in…

A group of words, labeled the core vocabulary, can be expected to be prominent across all texts. Scholarship made possible by digital databases of words and new analytic systems has shown that approximately 2,500 morphological families account for most of the words in texts--an average of 91.5% of all words in the Common Core State Standards…

Socioeconomic status (SES)-related language gaps are known to widen throughout the course of the school years; however, not all children from lower SES homes perform worse than their higher SES peers on measures of language. The current study uses mediation and moderated mediation to examine how cognitive and language abilities (vocabulary,…

The ability to make inferences is essential for effective language comprehension. While inferencing training benefits reading comprehension in school-aged children (see Elleman, 2017, for a review), we do not yet know whether it is beneficial to support the development of these skills prior to school entry. In a pre-registered randomised…

We report on a meta-analysis designed to test the theory that instruction that involves direct teaching of academic vocabulary and teaching strategies to determine the meaning of unknown words develops students' abilities to infer new words' meanings and builds students' overall vocabulary knowledge. We meta-analyzed 39 experimental and…

Morphological awareness, or sensitivity to units of meaning, is an essential component of reading comprehension development. Current neurobiological models of reading and dyslexia have largely been built upon phonological processing models, yet reading for meaning is as essential as reading for sound. To fill this gap, the present study explores…

Purpose: Vocabulary intervention can improve comprehension of texts containing taught words, but it is unclear if all middle school readers get this benefit. This study tests 2 hypotheses about variables that predict response to vocabulary treatment on text comprehension: gains in vocabulary knowledge due to treatment and pretreatment reading…

Teaching a homograph by using context clues is more effective than just teaching vocabulary separately. The goal of the study reported on here was to teach 12 homographs to d/Deaf and Hard of Hearing (d/Dhh) students in the sixth grade by applying metacognitive skills to understand the meanings and contexts in sentences. A single case design…

The vocabulary deficit shown by English Learners (ELs) has become evident among many educators over decades of research (Becker, 1977; Biemiller, 2001; Chall, Jacobs, & Baldwin, 1990; Hart & Riseley, 2003), and has shown that a student's limited vocabulary becomes a "major barrier to school success" (Graves, 2005, p. 18).…

This study attempted to answer the following research questions related to the various vocabulary discovery strategies which are used by Saudi undergraduate learners to find unknown word meanings, the most and the least vocabulary discovery strategies the learners used to discover unknown word meanings, the relationship between the type of…

Building vocabulary knowledge, especially breadth and depth of word meanings, is a crucial step in assisting students to read and comprehend print independently. A large body of research has documented the low reading achievement levels of a number of Deaf and hard-of-hearing (DHH) students. The goal of the present study was to examine the effects…

Background: In countries with German as an official language, children with German as a second language perform overall worse in school than their German native speaking peers. This particularly affects written language skills, which require advanced language knowledge. The reasons are manifold, but one is prominent, namely poor vocabulary…

The type of processing-resource allocation (TOPRA) model predicts that the semantic processing of new second language (L2) words can impede the learning of their forms while structural processing can promote it. Using this framework, the present study examined the effects of processing type (semantic, structural, control), exposure frequency (one…
