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…

This study examined the differential effects of Strategies for Reading Informational Text and Vocabulary Effectively (STRIVE) on the vocabulary, reading comprehension, and content learning among 4,757 fourth-grade students with and without disabilities. Schools were assigned to one of three conditions: researcher-supported professional development…

In this experimental study, we examined the effects of a multicomponent reading comprehension intervention in sixth- to eighth-grade English language arts classes with a focus on factors to enhance treatment implementation. We tested the contribution of a theoretically derived fidelity framework that included adherence, quality, dosage, program…

The authors examine the results for students with disabilities from a 2-year randomized controlled trial with students identified in ninth grade and followed through 10th grade in their allotted condition group. Prior to ninth grade, students with disabilities who met criteria for low reading comprehension (i.e., through failure on the state…

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…

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…

A 2-year, randomized control trial with 9th to 10th grade students with significant reading problems was provided for 50 minutes a day in small groups. Comparison students were provided an elective class and treatment students the reading intervention. Students were identified as demonstrating reading difficulties through failure on their state…

This study investigated the relative effects of three treatments with varying instructional emphases in reading with a comparison condition. Eighty-seven students in fourth grade with reading impairments were assigned through stratified random assignment to one of four conditions: (a) comprehension emphasis, (b) word study emphasis, (c) emphasis…

In this experimental study we examined the effects of integrating teacher-directed knowledge-building and student-regulated comprehension practices in 7th- to 10th-grade English language arts classes. We also investigated the effect of instructional quality and whether integrating practices differentially benefitted students with lower entry-level…

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…
