This study utilized secondary analyses of a randomized controlled trial and investigated the extent to which prestest word identification efficiency, reading fluency, and vocabulary knowledge moderated the effects of an intervention on reading comprehension outcomes for struggling readers in sixth through eighth grades. Given that the experimental…

This study sought to better understand the prevalence of concurrent and specific difficulties in reading fluency and vocabulary among adolescents with low reading comprehension. Latent class analysis (LCA) was used to identify a sample of 180 students in sixth through eighth grades with reading comprehension difficulties. A subsequent LCA…

This article illustrates the value of large-scale impact evaluations with counterfactual components. It begins by exploring the limitations of small-scale impact studies, which do not allow reliable inference to a wider population or which do not use valid comparison groups. The paper then describes the design features of a recent large-scale…

An appropriate estimate of statistical power is critical for the design of intervention studies. Although the inclusion of a pretest covariate in the test of the primary outcome can increase statistical power, samples selected on the basis of pretest performance may demonstrate range restriction on the selection measure and other correlated…

This experimental study examined the effectiveness of a text-based reading and vocabulary intervention with self-regulatory supports for 4th graders with low reading comprehension. Students with standard scores on the Gates MacGinitie Reading Test between 1.0 standard deviation (SD) and 0.5 SD below the normative sample were included (N=44) and…

Sixty fourth- and fifth-grade general education teachers were randomly assigned to teach Collaborative Strategic Reading (CSR; Klingner, Vaughn, Boardman, & Swanson, 2012), a set of reading comprehension strategies, or to a business-as-usual comparison group. Results demonstrate that students with learning disabilities (LD) who received CSR…

Reading and comprehending content area texts require learners to effectively select and encode with hierarchically strategic memory structures in order to combine new information with prior knowledge. Unfortunately, evidence from state and national tests shows that children fail to successfully navigate the reading comprehension challenges they…

The present study used a randomized control trial to examine the effects of a widely used multicomponent Tier 2-type intervention, Passport to Literacy, on the reading ability of 221 fourth graders who initially scored at or below the 30th percentile in reading comprehension. Intervention was provided by research staff to groups of 4-7 students…

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…

This article examines the effects of one year of exposure to "Learning to Read in a Healing Classroom" (LRHC) on the reading and math skills of second- to fourth-grade children in the low-income and conflict-affected Democratic Republic of the Congo. LRHC consists of two primary components: teacher resource materials that infuse…

The present study aims to contribute to the understanding of the effects of music education, in particular music composition as a classroom activity for fifth- and sixth-graders. The intervention (experimental condition) focused on a three-step-model for music composition, based on the Cultural Historical Activity Theory of education, and has been…

It is essential for learners to develop foundational literacy skills, ideally, in the first grade of formal education. These skills are then firmly entrenched and can be expanded in the following grades to form a basis for all future academic studies. Appropriate assessment practices and tools to aid this process can inform the achievement of…

Using reliable and valid measures of students' outcomes which are sensitive to change is critical for obtaining interpretable and therefore useful results from evaluations of school-based interventions. While measurement development for use in experimental evaluations receives a great deal of attention in the U.S., it lags behind in low-income…

With the increased population of English learners (ELs), educators need programs that help students access academic content while learning to understand, speak, read, and write English (Tharp, Estrada, Dalteen, & Yamaguchi 2000; Echevarria, Short & Powers, 2006). ELs come into U.S. schools needing to learn the same grade-level content as…
