We present an aggregation scheme that increases power in randomized controlled trials and quasi-experiments when the intervention possesses a robust and well-articulated theory of change. Intervention studies using longitudinal data often include multiple observations on individuals, some of which may be more likely to manifest a treatment effect…

Purpose: Researchers have developed a constellation model of decodingrelated reading disabilities (RD) to improve the RD risk determination. The model's hallmark is its inclusion of various RD indicators to determine RD risk. Classification methods such as logistic regression (LR) might be one way to determine RD risk within the constellation…

Reading difficulties may have multiple causes. Effective approaches to reading intervention need to target the specific causes for individual readers. The Early Reading Intervention Knowledge program comprises three intervention pathways: a phonological-phonemic pathway, a phonic-orthographic pathway, and an oral language pathway. This study…

Student achievement in reading comprehension has been an important topic for the past several years due to the importance of reading in education. School districts in South Carolina have had enormous amounts of pressure put on them to increase student reading comprehension through the implementation of SLOs and the Read to Succeed initiative. The…

The problem investigated in this quantitative study was that schools in a small, rural East Texas town were falling below acceptable ratings in reading on the Texas Assessment of Knowledge and Skills (TAKS) and the State of Texas Assessment of Academic Readiness (STAAR). Researchers have found that constructive-based learning environments (CBLEs)…

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…

The authors examined the implementation of a blended learning program for literacy instruction across kindergarten through Grade 5 in a Title I urban elementary school, including a population of students (18%) who are English learners. Student progress in the online component of the blended learning program was a significant predictor of growth in…

In a common approach for scaling up effective educational practice, schools adopt evidence-based programs to be implemented with fidelity. An alternative approach assumes that programs should be adapted to local contexts. In this randomized trial of a reading intervention, we study a scaffolded sequence of implementation in which schools first…

Theory and empirical work suggest that teachers' social capital influences school improvement efforts. Social ties are prerequisite for social capital, yet little causal evidence exists on how malleable factors, such as instructional management approaches, affect teachers' ties. In this cluster-randomized trial, we apply a decision-making…

This multiyear scale-up effectiveness study of Open Court Reading (OCR) involved approximately 4,500 students and more than 1,000 teachers per year in Grades K-5 from 49 elementary schools in seven districts across the country. Using a school-level cluster randomized trial design, we assessed the implementation and effectiveness of Open Court…

Summer reading loss is a prevalent problem that occurs primarily for students who are not exposed to or encouraged to read at home or in summer programs when school is out. This problem prevails among early readers from low-income backgrounds. This study provided 31 six and seven-year-old children with a structured guided reading program through…

National assessments have shown that the majority of students in the United States cannot read at grade level by fourth grade. These results are alarming because students who are not proficient readers by third grade suffer long-term consequences and are more likely to drop out of high school. Feeling pressure to improve reading outcomes, schools…

Students who struggle to read on grade level by the end of third grade are less likely to make academic progress and graduate before the age of 19. The district leaders in a suburban district in Texas were interested in determining the root cause of stagnant reading standardized test scores. After determining the root cause, a lack of a…

The aim of this study was to reveal how reading comprehension skills of elementary fourth graders who have problems in reading comprehension can be improved by means of the SCRATCH program. The study was designed as a participant action research. It was carried out within a 15- week process at an elementary school with middle socio-economic level…

This study seeks to explain what first- and second-grade African American, urban students who participated in an explicit comprehension strategy instruction (ECSI) program learned about comprehension strategies and how this knowledge supports self-regulated strategy use. The study was also designed to compare these students' knowledge with those…
