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…

This article describes evidence-based practices that beginning special education teachers can readily implement in special or general education settings that promote reading and content outcomes for students with disabilities as well as general education students. We describe two approaches: (a) Promoting Adolescents' Comprehension of Text (PACT),…

Supporting the reading comprehension and content knowledge acquisition of English language learners (ELs) requires instructional practices that continue beyond developing the foundational skills of reading. In particular, the challenges ELs face highlight the importance of teaching reading comprehension practices in the middle grades through…

This study aimed to replicate findings that demonstrated impact on students' reading comprehension and social studies content learning. Using a randomized control trial, intervention, and outcome measures, this study was replicated in 85 8th-grade social studies classes with 19 teachers. Teachers were provided professional development on…

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…

This study aimed to determine the efficacy of a content acquisition and reading comprehension treatment implemented by eighth-grade social studies teachers. Using a within-teacher design, the eighth-grade teachers' social studies classes were randomly assigned to treatment or comparison conditions. Teachers (n = 5) taught the same instructional…

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…

This study examines the interaction between the fidelity of implementation of a set of research-based strategies--Collaborative Strategic Reading (CSR)--and outcomes for students with mild to moderate disabilities using data from two nonoverlapping studies in middle school language arts and reading classrooms (Study 1) and middle school social…

In this study, we examined the extent to which teachers' treatment adherence, instructional quality, and the interaction of these variables influenced eighth-grade students' content knowledge and reading comprehension. We examined treatment fidelity for students (n = 775) in classes randomly assigned to receive an evidence-based content area…

When recommending a program to achieve objectives such as improving learning outcomes for middle school students, school psychologists need information about cost-effectiveness to identify the best fit for student needs and school budgets. However, few cost studies of evidence-based instructional programs exist. We compared the cost-effectiveness…

This study investigated the effects of Promoting Adolescent Comprehension Through Text (PACT), a content knowledge and comprehension treatment for English learner and non--English learner students with disabilities who were provided instruction in general education social studies classrooms. Eighth-grade students with disabilities in the treatment…

Collaborative Strategic Reading (CSR) is a multicomponent reading intervention aimed at improving students' text comprehension. Two 1-year randomized controlled trials were conducted to determine the efficacy of CSR with seventh and eighth grade students. The Year 2 replication study was identical to the original Year 1 study except that the…

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…

This study examined the effects and fidelity of collaborative strategic reading (CSR) implemented by experienced CSR teachers (participated in previous study; Vaughn et al., 2011) on the reading comprehension outcomes of students in English/Language Arts (ELA) or Reading classes. Eligible teachers (12 of 17; others reassigned to teach…

Significant numbers of adolescents and young adults do not adequately understand complex texts, impeding their school success, access to postsecondary learning, and opportunities within an increasingly competitive work environment. National data (National Assessment of Educational Progress [NAEP], 2015) have shown improvements among fourth- and…
