Recent initiatives in the UK and the US have added greatly to the amount and quality of research on the effectiveness of secondary reading programmes, especially programmes for struggling readers. This review of the experimental research on secondary reading programmes focuses on 69 studies that used random assignment (n=62) or high-quality…

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…

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 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…

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 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 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 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 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 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 systematically reviews research on the achievement outcomes of four types of approaches to improving the reading success of children in the elementary grades: reading curricula, instructional technology, instructional process programs, and combinations of curricula and instructional process. Study inclusion criteria included use of…

This study reports the results of a best-evidence synthesis of research on the use of one-to-one tutoring delivered by adults to students in the primary grades who are learning to read. The synthesis includes research on five programs: Reading Recovery, Success for All, Prevention of Learning Disabilities, the Wallach Tutorial Program, and…

This document contains a brief summary of research on the Success for All comprehensive school reform program and the alignment document that outlines the correlation between Success for All and the objectives and outcomes described in the Stanford Achievement Test: Ninth Edition (SAT-9) as designed by Harcourt, Inc. Research has found Success for…

Much more is known about how to best prevent and remediate learning deficits than is being applied. However, much remains to be learned about effective programs for students at risk of failure. Major restructuring of compensatory and special education programs in the early grades is needed to ensure all students an adequate level of basic skills…
