While the extant literature emphasizes the role of Phonological Awareness (PA) and Rapid Automatized Naming (RAN) in children's developing reading comprehension and vocabulary acquisition skills, there has been a paucity of information on the contributions made by other factors such as Morphological Awareness (MA). Although evidence of a…

Understanding the factors associated with variation in the implementation of educational programs has emerged as a key research focus, in an effort to identify how promising programs can be scaled up across their targeted contexts. The current study explored demographic-related variation in program dosage using a novel source of implementation…

Background: Vocabulary knowledge (VK) and morphological awareness (MA) are crucial linguistic variables for reading comprehension. However, the extent to which MA subskills are intertwined with different facets of VK in their contributions to reading comprehensions, and how MA influences the reading abilities of English as a foreign language (EFL)…

Few studies aimed to disentangle different aspects of vocabulary depth (VD) knowledge and examine their contribution to second-language (L2) reading comprehension. To fill this gap, this study distinguished between two VD aspects, that is, semantic network knowledge and polysemous knowledge; and tested how they, together with vocabulary size (VS),…

Vocabulary is an important prerequisite for reading comprehension and therefore for learning in all subjects. For this reason, the present study examines digital context-based and explicit approaches to vocabulary promotion in an experimental intervention study in fourth grade. Furthermore, students' reading comprehension and intrinsic reading…

Purpose: We measure typically developing monolingual child Spanish speakers' lexical development with a range of standard expressive and receptive tests. We also measure their comprehension of sentences with the existential quantifier "algunos" "some" to determine their abilities to generate "some, but not all" scalar…

To achieve efficient reading comprehension, Chinese as a second language (L2) learners adopt various component skills and knowledge, including the aspects of vocabulary, grammar, and coherence. However, there is no consensus regarding the relative predictive powers of these three areas in L2 reading comprehension. Instead of employing direct…

This study investigated the relation between Dual Language Learners' (N = 90) vocabulary and grammar comprehension and word learning processes in preschool (aged 3-through-5 years). Of interest was whether: (a) performance in Spanish correlated with performance in English within each domain; and (b) comprehension predicted novel word learning…

Oral language comprehension (OLC) and vocabulary depth are widely recognized as key predictors of reading comprehension. However, research has either provided a limited representation of OLC or failed to acknowledge the distinctive predictive nature of vocabulary depth. This study investigates the combined contributions of OLC, conceptualized as a…

The purpose of this paper is to (a) establish whether meaning recall and meaning recognition item formats test psychometrically distinct constructs of vocabulary knowledge which measure separate skills, and, if so, (b) determine whether each construct possesses unique properties predictive of L2 reading proficiency. Factor analyses and…

In the present study, we aimed to compare reading-writing relations between first-grade Native English Speakers (NESs) and English Language Learners (ELLs). Thirty-four ELLs and 35 NESs completed measures of receptive and expressive vocabulary, lexical-level reading (word reading) and writing (spelling), and discourse-level reading (reading…

We explored reading comprehension development in children on the spectrum from pre-school to the first (YOS1) and third year of schooling (YOS3). Children were first assessed on meaning-related skills in pre-school. Forty-one children completed follow-up assessments of reading comprehension, reading accuracy, and listening comprehension in YOS1.…

The unprecedented growth of Spanish-English dual language learners (DLLs) in new destination states (e.g., Georgia, Indiana, South Carolina, Tennessee) calls for better understanding of the relation between their bilingual vocabulary skills and English reading achievement. The current study focused on school-age Spanish-English DLLs (N = 60) in…

This study investigated the relation between Dual Language Learners' (N = 90) vocabulary and grammar comprehension and word learning processes in preschool (aged 3-through-5 years). Of interest was whether: (1) performance in Spanish correlated with performance in English within each domain; and (2) comprehension predicted novel word learning…

Literacy assessment is essential for effective literacy instruction and training. However, traditional paper-based literacy assessments are typically decontextualized and may cause stress and anxiety for test takers. In contrast, serious games and game environments allow for the assessment of literacy in more authentic and engaging ways, which has…
