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…

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…

As evidence-based reform becomes increasingly important in educational policy, it is becoming essential to understand how research design might contribute to reported effect sizes in experiments evaluating educational programs. The purpose of this study was to examine how methodological features such as types of publication, sample sizes, and…

This study aims to present the design and pilot testing procedures of the two specific self-report questionnaires were used to measure the two key aspects of reading motivation, self-efficacy and intrinsic motivation in the field of literary (narrative) reading, and the partial factors that jointly shape them. These instruments were outlined in…

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…

Students who acquire reading comprehension using arts integration will have the opportunity to improve their ability to learn through the following subjects writing, science, language arts, social studies, and mathematics. The problem is economically disadvantaged third-, fourth-, and fifth-grade students did not make adequate yearly gains or pass…

The purpose of the current study was to investigate the difference in pro-social behavior, self-regulation, overall reading performance, Lexile levels, and teachers' perception of classroom climate of kindergarten students who received the Ready to Learn (RTL; Brigman, Lane, & Lane, 2008) classroom guidance program (treatment group: n = 173)…

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…

Background/Context: In a recent review of culturally relevant instruction and reading comprehension, Fairbanks, Cooper, Masterson, and Webb (2009) highlighted the paucity of research available to support the widespread claim in the literacy field that "students' social and cultural practices are deeply intertwined with literacy learning"…

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…

Reading buddies programs, which pair older and younger students to read books together on a regular basis, are common in many U.S. elementary schools. Yet, the research base on these programs is limited. Therefore, we conducted a quasiexperimental study of a reading buddies program targeting vocabulary and comprehension. The program we studied…

The purpose of this quantitative, quasi-experimental study was to test the theory of using high frequency word list (HFWL)-based instruction when teaching beginning reading instruction. This study compared the reading fluency changes of eight classes across three different grades containing 115 students over 5 months as measured by the…

This study relates to the results obtained in the development of reading comprehension (RC) and self-concept as a reader in students who participated in "Llegim en parella" ("Reading in pairs"), a Catalan peer tutoring programme. The research combines a quasi-experimental design with the use of comparison groups and…

Improvements in students' learning achievement have lagged behind in low-and middle-income countries despite significant progress in school enrollment numbers. Large-scale early grade reading assessments (e.g., "Annual Status of Education Report" [ASER], 2013; EdData II, n.d.) have shown low reading rates and worryingly high…

Successful school reform is dependent on the quality of decisions made by educational leaders. In such decision making, educational leaders are charged with using sound research findings as the basis for choosing school reform initiatives. As part of the debate regarding the usability of various evaluative research designs in providing information…
