The number of students assigned to special education has increased in the past decades, in spite of efforts for more inclusion. For students with mild learning or behavioral difficulties, special education assignment might be prevented if appropriate support is provided in general education. In this study, research on programs that could reduce…

This systematic review of research on early childhood programs seeks to identify effective approaches capable of improving literacy and language outcomes for preschoolers. It applies consistent standards to determine the strength of evidence supporting a variety of approaches, which fell into two main categories: "comprehensive…

This article presents a systematic review of research on the achievement outcomes of all types of approaches to teaching science in elementary schools. Study inclusion criteria included use of randomized or matched control groups, a study duration of at least 4 weeks, and use of achievement measures independent of the experimental treatment. A…

This article reports a systematic review of research on science programs in grades 6-12. Twenty-one studies met inclusion criteria including use of randomized or matched assignment to conditions, measures that assess content emphasized equally in experimental and control groups, and a duration of at least 12 weeks. Programs fell into four…

This review examines the effectiveness of educational technology applications in improving the reading achievement of struggling readers in elementary schools. The review applies consistent inclusion standards to focus on studies that met high methodological standards. A total of 20 studies based on about 7,000 students in grades 1-6 were included…

The present review examines research on the effects of educational technology applications on mathematics achievement in K-12 classrooms. Unlike previous reviews, this review applies consistent inclusion standards to focus on studies that met high methodological standards. In addition, methodological and substantive features of the studies are…

This article summarises findings from systematic reviews of research on primary and secondary mathematics, primary and secondary reading, and programmes for struggling readers. All reviews used a common set of procedures, requiring comparisons with control groups and duration of at least 12 weeks. Across hundreds of qualifying studies, a clear…

This article presents a systematic review of research on the achievement outcomes of all types of approaches to teaching science in elementary schools. Study inclusion criteria included use of randomized or matched control groups, a study duration of at least 4 weeks, and use of achievement measures independent of the experimental treatment. A…

This article reviews research on the achievement outcomes of alternative approaches for struggling readers ages 5-10 (US grades K-5): One-to-one tutoring, small-group tutorials, classroom instructional process approaches, and computer-assisted instruction. Study inclusion criteria included use of randomized or well-matched control groups, study…

In recent years, there has been a revival of interest in financial incentives to encourage students to attend school and to improve their academic achievement, graduation rates, and other outcomes. Conditional cash transfers programmes in developing countries, especially PROGRESA in Mexico, have found positive effects on attendance in large-scale…

This guide summarizes "Effective Programs for Struggling Readers: A Best Evidence Synthesis," a research review conducted by Johns Hopkins University's Center for Research and Reform in Education. The purpose of the review was to evaluate the achievement outcomes of alternative approaches for struggling readers in grade K-5: (1) one-to-one…

The use of educational technology in K-12 classrooms has been gaining tremendous momentum across the country since the 1990s. Many school districts have been investing heavily in various types of technology, such as computers, mobile devices, internet access, and interactive whiteboards. Almost all public schools have access to the internet and…

This article reviews research on the achievement outcomes of mathematics programs for middle and high schools. Study inclusion requirements include use of a randomized or matched control group, a study duration of at least 12 weeks, and equality at pretest. There were 100 qualifying studies, 26 of which used random assignment to treatments. Effect…

This guide summarizes "Effective Programs in Elementary Mathematics: A Best-Evidence Synthesis" and "Effective Programs in Middle and High School Mathematics: A Best-Evidence Synthesis," two research reviews conducted by Johns Hopkins University's Center for Research and Reform in Education. The purpose of the reviews was to evaluate the…

The present review examines research on the effects of technology use on reading achievement in K-12 classrooms. Unlike previous reviews, this review applies consistent inclusion standards to focus on studies that met high methodological standards. In addition, methodological and substantive features of the studies are investigated to examine the…
