Vocabulary is a prominent contributor to reading comprehension. However, little is known about how students with disabilities with lower vocabulary performance respond to Tier 1 instruction, or how their vocabulary knowledge relates to their content acquisition. To examine the differential impact of Tier 1 instruction for U.S. middle school…

With a focus on content-area reading, this study aimed to (a) understand the sources and prevalence of concurrent and specific difficulties in word-level skills, vocabulary, and knowledge among adolescent struggling readers (ASRs) and (b) explore the relations among reading skills, profiles, and reading comprehension. A dual-measure screening…

The purpose of this study is to identify to what extent that the reading comprehension, question types, attitude toward science, test method, and subject matter knowledge predict the PISA scientific literacy scores of the students. The study uses the method of correlational research, which is a type of quantitative research method. We reached out…

We examined the efficacy of a content acquisition and reading comprehension intervention implemented in eighth-grade social studies classrooms. Using a within-teacher randomized control design, 18 eighth-grade teachers' social studies classes were randomly assigned to a treatment or comparison condition. Teachers taught all their classes…

We examined the influence of teachers' use of instructional time on students' learning within the context of a randomized controlled trial investigating the effects of a content-area reading comprehension intervention. Participants were 8th grade social studies teachers who had their classes randomly assigned to either Promoting Acceleration of…

The present study investigated whether text structure inference skill (i.e., the ability to infer overall text structure) has unique predictive value for expository text comprehension on top of the variance accounted for by sentence reading fluency, linguistic knowledge and metacognitive knowledge. Furthermore, it was examined whether the unique…

Students with disabilities are often included in general education social studies classes, but these classes can differ in the achievement level of the overall class, including wide variation in content-related background knowledge, reading achievement, or both. The purpose of this study was to examine how background knowledge and reading…

America is in a reading crisis. The authors of this new report point out, two in three American fourth-graders are performing below proficient in the National Assessment of Education Progress (NAEP)--known as the "Nation's Report Card." There's another troubling component to this crisis. Important segments of society are being left…

Deficits in academic vocabulary knowledge plague students who struggle with reading and impact their reading comprehension and performance in content area courses. Experts have developed interventions aimed at improving vocabulary instruction. However, questions remain concerning the effects of vocabulary gains on reading comprehension and content…

This study explored the relationship between two dimensions of vocabulary knowledge, that is, breadth of vocabulary (the number of words known) and depth of vocabulary (the richness of word knowledge), and their effects on different aspects of English reading in Chinese high school students learning English as a second language. Two hundred and…

Component skills and discourse frameworks of reading have identified characteristics of readers and texts that influence comprehension. However, these 2 frameworks have not previously been integrated in a comprehensive and systematic way to explain performance on any standardized assessment of reading comprehension that is in widespread use across…

In a longitudinal design, we measured 50 low-achieving adolescents' reading comprehension development from Grades 7 to 9. There were 24 native Dutch and 26 language minority students. In addition, we assessed the roles of (a) linguistic knowledge, (b) metacognitive knowledge, and (c) reading fluency in predicting both the level and growth of…

This study aimed to determine the efficacy of a content knowledge and reading comprehension treatment implemented by eighth-grade general education social studies teachers among students with disabilities included in the classes. Data on students with disabilities across 2 years of study were combined for the analysis presented here. Students in…

As part of the National Assessment of Educational Progress (NAEP) in reading, students are asked to demonstrate their understanding of words as used in literary and informational texts. This focus on students' understanding of word meaning highlights the importance of vocabulary in reading comprehension. This report provides an overview of…

A conceptualization of reading as an interaction of constrained and unconstrained skills formed the theoretical basis for this correlational analysis of adolescents' orthographic knowledge. We hypothesized that orthographic development (as measured by spelling ability) would serve as a link between constrained and unconstrained reading skills in…
