Learning to read relies upon the integration of phonological, orthographic, and semantic information. However, no studies have investigated how children with varying reading abilities learn phonological-orthographic (PO) and semantic aspects of novel words as a function of both learning approach (LA; e.g., learning new words in isolation or…

Background: Middle school students use the information conveyed by morphemes (i.e., units of meaning such as prefixes, root words and suffixes) in different ways to support their literacy endeavours, suggesting the likelihood that morphological knowledge is multidimensional. This has important implications for assessment. Methods: The current…

Purpose: The current study takes a practical and theoretically grounded look at assessment of morphological knowledge and its potential to deepen understanding of how morphological knowledge supports reading comprehension for students with limited reading vocabulary. Specifically, we explore how different morphological skills support reading…

Researchers have investigated that different dimensions of word knowledge (breadth versus depth) may play distinct roles in second language (L2) reading comprehension. Yet, little research has addressed how learners' efficiency of accessing those dimensions of knowledge functions in their comprehension (i.e., the issue of knowledge availability…

In an intelligent tutoring system (ITS), it can be useful to know when a student has disengaged from a task and might benefit from a particular intervention. However, predicting disengagement on a trial-by-trial basis is a challenging problem, particularly in complex cognitive domains. In the present work, data-driven methods were used to address…

The purpose of this research is to develop a vocabulary assessment, Evaluation of Academic Vocabulary or "EAV," that gauges students' depth of knowledge of academic words and is sensitive to vocabulary growth in the context of literacy interventions. We report results from two studies with native English-speaking middle school students…

This study set out to compare patterns of relationships among phonological skills, orthographic skills, semantic knowledge, listening comprehension, and reading comprehension in English as a first language (EL1) and English language learners (ELL) students and to test the applicability of the lexical quality hypothesis framework. Participants…

Testing a component model of reading comprehension in a randomized controlled trial, we evaluated the efficacy of 4 interventions that were designed to target components of language and metacognition that predict children's reading comprehension: vocabulary, listening comprehension, comprehension of literate language, academic knowledge, and…

This study investigated how middle school students leverage information about bound Latin roots (e.g., "voc" in "advocate" and "vociferous") to infer meanings of unfamiliar words, and how instruction may facilitate morphological analysis using roots. A dynamic assessment of morphological analysis was administered to…

A dynamic assessment of morphological analysis was administered to 29 sixth…

Word learning can build the high-quality word representations that support skilled reading and language comprehension. According to the partial knowledge hypothesis, words that are partially known, a.k.a. "frontier words" (Durso & Shore, 1991), may be good targets for instruction precisely because they are already familiar. However,…

This study explored effects of Spanish oral language skills (vocabulary and syntax) on the development of English oral language skills (vocabulary, morphology, semantics, syntax) and reading comprehension among 156 bilingual Latino children in second through fifth grade whose first language was Spanish and whose second language was English. Using…
