As evidence becomes increasingly important in educational policy, it is essential to understand how research design might contribute to reported effect sizes in experiments evaluating educational programs. A total of 645 studies from 12 recent reviews of evaluations of preschool, reading, mathematics, and science programs were studied. Effect…

This meta-analysis synthesizes the last two decades of experimental and quasi-experimental research on reading instruction across academic contexts (e.g., social studies, science, mathematics, English language arts) for English learners (ELs) in grades 4 through 8, to determine (a) the overall effectiveness of reading instruction for upper…

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…

This article contains a synthesis of academic intervention studies conducted between 1970 and 2012 with adolescents who were incarcerated in residential juvenile correctional facilities. Literacy, mathematics, written expression, and multicomponent interventions were included if they measured effects on at least one academic outcome measure. Of…

The purpose of the present review was to evaluate the quality of the research and evidence base for representation of problems as a strategy to enhance the mathematical performance of students with learning disabilities and those at risk for mathematics difficulties. The authors evaluated 25 experimental and quasiexperimental studies according to…

Much is known about short-term--but very little about the long-term--effects of reading interventions. To rectify this, a detailed analysis of follow-up effects as a function of intervention, sample, and methodological variables was conducted. A total of 71 intervention-control groups were selected (N = 8,161 at posttest) from studies reporting…

Drawing on interactionist and socio-cultural theories, tools provided in computer-mediated communication (CMC) environments have long been considered able to create an environment that shares many communicative features with face-to-face communication. Over the past two decades, researchers have employed a variety of strategies to examine the…

Research Findings: The early childhood years are critical in developing early mathematics skills, but the opportunities one has to learn mathematics tend to be limited, preventing the development of significant mathematics learning. By conducting a meta-analysis of 29 experimental and quasi-experimental studies that have been published since 2000,…

Autism spectrum disorders are characterised by impairments in communication and social interaction. Social skills interventions have been found to ameliorate socio-communication deficits in children and adolescents with autism spectrum disorders. Little is known about the effectiveness of social skills interventions for adults with…

Though research on effective instruction in math word problem solving is prominent at the middle and secondary levels, much less work has been done in elementary grades. In this article, we review the research on varied problem-solving instructional interventions at the third-grade level for students across ability levels. Third grade was chosen…

Special education in Saudi Arabia was formally established in 1962. The earliest cited literature on special education written in English was a 1970 government report. This article presents results from the first synthesis of internationally published Saudi special education literature over a 44-year period. This synthesis yielded information…

Studies of the competition effects from voucher or tuition tax credit scholarship programs on public school student academic outcomes have taken place in seven locations throughout the United States, with the majority of studies taking place in Florida, followed by Wisconsin. This article reviews 21 total studies of the impacts on student academic…

The purpose of this review was to better understand the impact of universal campaign interventions with a media component aimed at preventing child physical abuse (CPA). The review included 17 studies featuring 15 campaigns conducted from 1989 to 2011 in five countries. Seven studies used experimental designs, but most were quasi-experimental. CPA…

Project-based learning (PBL) is an active student-centred form of instruction which is characterised by students' autonomy, constructive investigations, goal-setting, collaboration, communication and reflection within real-world practices. It has been explored in various contexts and in different phases of schooling, from primary to higher…

School nurses are tasked with the critical job of keeping students safe and well. Due to competing demands for resources in schools, the impact of school nurses must be demonstrated to secure their jobs. A systematic review of the literature from 1937 to 2013 was conducted to show the efficacy of school nursing activities in American elementary…
