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…

Success for All (SFA) is a comprehensive whole-school approach designed to help high-poverty elementary schools increase the reading success of their students. It is designed to ensure success in grades K-2 and then build on this success in later grades. SFA combines instruction emphasizing phonics and cooperative learning, one-to-small group…

In this article, we review research on the outcomes of diverse reading programs on the achievement of struggling readers in elementary schools. Sixty-five studies of 51 different programs met rigorous standards. Eighty-three percent were randomized experiments and 17% quasi-experiments. Outcomes were positive for one-to-one tutoring and were…

This paper reviews research on outcomes of writing programs for students in grades 2 to 12. Studies had to meet rigorous standards of research including use of randomized or well-matched control groups, measures independent of the program developers, researchers, and teachers, and adequate sample size and duration. Fourteen studies of 12 programs…

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 study examined the effects of the Success for All (SFA) whole-school reform approach on student reading achievement. The data were collected for the Study of Instructional Improvement by the University of Michigan, which did not previously report the achievement outcomes in detail but did make the data available online. Using propensity…

This paper reviews research on outcomes of writing programmes for students in Years 3 to 13 in England, or grades 2 to 12 in the US. Studies had to meet rigorous standards of research including use of randomised or well-matched control groups, measures independent of the programme developers, researchers, and teachers, and adequate sample size and…

Many disadvantaged students with refractive errors, such as myopia (nearsightedness) and hyperopia (farsightedness), do not have eyeglasses, and their reduced vision may impact reading proficiency. Providing eyeglasses may increase their reading success. This article reports the findings of a study in Baltimore City in which disadvantaged second…

This article reviews research on the achievement outcomes of elementary mathematics programs. 85 rigorous experimental studies evaluated 64 programs in grades K-5. Programs were organized in 6 categories. Particularly positive outcomes were found for tutoring programs. Positive outcomes were seen in studies focused on professional development for…

This article reviews research on the mathematics achievement outcomes of all programs with at least one study meeting inclusion criteria. 78 studies evaluated 61 programs in grades K-5. The studies were very high in quality, with 65 (83%) randomized and 13 (17%) quasi-experimental evaluations. Programs were organized in 8 categories. Particularly…

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 quasi-experimental 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…

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…

What matters most in education is what teachers do in the classroom to enhance student achievement. For this reason, state and district leaders must take steps to ensure that principals and teachers have effective textbooks, software, professional development, and programs. The Every Student Succeeds Act (ESSA) moves away from the…

Despite widespread recognition among policy makers, educational leaders, and the nation as a whole of the importance of science, engineering, and technology as drivers of the future of the country and society, the science achievement of America's students is mediocre at best, in comparison to that of international peers. On the 2012 PISA tests in…

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…
