It is widely recognized that individuals with dyslexia have difficulties with word reading "and" spelling, and individuals with reading comprehension difficulties have low vocabulary knowledge. However, little is known about the extent to which spelling and vocabulary are informative of reading difficulties. In the present study, we…

Purpose: This study explores the roles of morphological skills (Morphological Awareness, Morphological-Syntactic-Knowledge, Morphological-Semantic-Knowledge, and Morphological-Orthographic/Phonological-Knowledge), vocabulary (knowledge of definitions, relationships between words, and polysemous meanings), and syntax in contributing to adolescent…

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…

Text reading fluency refers to the ability to read connected texts with accuracy, speed, and expression (prosody), and has garnered substantial attention as an important skill for reading comprehension. However, two fundamental questions remain--the dimensionality of text reading fluency including text reading efficiency (accuracy and speed) and…

This study examines blending of classroom- and family-based supports within a Multi-Tiered System of Support (MTSS). The present study focuses on a sample of Head Start children who are both experiencing poverty and scoring below early language and literacy screening benchmarks. This study begins to explore which combination of resources are the…

The authors describe Monster, PI, which is an app-based, gamified assessment that measures language skills (knowledge of morphology, vocabulary, and syntax) of students in grades 5-8 and provides teachers with interpretable score reports to drive instruction that improves vocabulary, reading, and writing ability. Specifically, the authors describe…

This study examined the effectiveness of the intensive implementation of a multicomponent reading intervention (Voyager Passport) with 306 fourth grade students with severe reading difficulties. Students with reading comprehension achievement below the 15%ile in the fall of fourth grade were randomly assigned to the intensive intervention or to…

We examined the relations between working memory, emergent literacy skills (e.g., phonological awareness, orthographic awareness, rapid automatized naming), word reading, and listening comprehension to online reading processes (eye movements), and their relations to reading comprehension. A total of 292 students were assessed on working memory and…

To expand our understanding of script-general and script-specific principles in the learning of letter names, we examined how three characteristics of alphabet letters -- their frequency in printed materials, order in the alphabet, and visual similarity to other letters -- relate to children's letter-name knowledge in four languages with three…

We investigated the contributions of multiple strands of factors--individual characteristics (struggling reader status, working memory, vocabulary, grammatical knowledge, knowledge-based inference, theory of mind, comprehension monitoring), a text feature (narrative vs. expository genre), and question types (literal and inferential)--to one's…

We investigated the dimensionality of various indicators of reading prosody, and the relations of word reading and listening comprehension to the identified dimension(s) of reading prosody, using longitudinal data from Grades 1 to 3. A total of 371 English-speaking children were assessed on oral text reading, word reading, and listening…

This paper introduces a new observation system that is designed to investigate students' and teachers' talk during literacy instruction, "Creating Opportunities to Learn from Text" (COLT). Using video-recorded observations of 2nd-3rd grade literacy instruction (N=51 classrooms, 337 students, 151 observations), we found that nine types of…

Our understanding about the developmental similarities and differences between oral and silent reading and their relations to reading proficiency (word reading and reading comprehension) in beginning readers is limited. To fill this gap, we investigated 368 first graders' oral and silent reading using eye-tracking technology at the beginning and…

Two widely studied language skills in relation to reading comprehension are listening comprehension skill and academic language proficiency. Although their constituent skills and theoretical accounts of how they are related to reading comprehension share a large overlap, they have been studied in separate lines of work. In this study, we…

Complex data structures are ubiquitous in psychological research, especially in educational settings. In the context of randomized controlled trials, students are nested in classrooms but may be cross-classified by other units, such as small groups. Further, in many cases only some students may be nested within a unit while other students may not.…
