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…

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…

The assessment of screening accuracy and setting of cut points for a universal screener have traditionally been evaluated using logistic regression analysis. This analytic technique has been frequently used to evaluate the trade-offs in correct classification with misidentification of individuals who are at risk of performing poorly on a later…

We modeled word reading growth in typically developing (n = 118) and children with dyslexia (n = 20), Grades 2-5, across multiple exposures to 30 words. We explored the facilitative versus inhibitory effects of exposures to differential mixes of words that support high- versus low-frequency vowel pronunciations. One training corpus contained a…

As children learn to read, they become sensitive to context-dependent vowel pronunciations in words, considered a form of statistical learning. The work of Treiman and colleagues demonstrated that readers' vowel pronunciations depend on the consonantal context in which the vowel occurs and reading experience. Using explanatory item-response models…

The purpose of this project evaluation was to assess the impact of data-based individualization (DBI) on the mathematics achievement of students with intensive mathematics learning needs, including students with disabilities. The evaluation study used a cluster randomized trial in which elementary schools were randomly assigned to treatment using…

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…

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…

The present study examined the reading comprehension and receptive vocabulary skills of children with poor reading comprehension despite adequate decoding using a regression-based matching technique. Participants included five cohorts of children who were identified as typical readers (N = 70,493 - 75,553) or as children with specific reading…

Understanding written language is crucial to academic success in all content areas. Ensuring a strong foundation in the components of written language--that is, the literacy skills of reading, writing, and oral language--is essential if students are to read with understanding and, thus, is a primary goal of early literacy instruction and of the…

The present study followed a sample of first-grade (N = 316, M[subscript age] = 7.05 at first test) through fourth-grade students to evaluate dynamic developmental relations between vocabulary knowledge and reading comprehension. Using latent change score modeling, competing models were fit to the repeated measurements of vocabulary knowledge and…

This study examined the structure of oral language and reading and their relation to comprehension from a latent variable modeling perspective in Kindergarten, Grade 1, and Grade 2. Participants were students in Kindergarten (n = 218), Grade 1 (n = 372), and Grade 2 (n = 273), attending Title 1 schools. Students were administered phonological…
