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…

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 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…

Recent initiatives in the United States and United Kingdom have added greatly to the amount and quality of research on the effectiveness of secondary reading programs, especially programs for struggling readers. In this review of the experimental research on secondary reading programs, the authors focused on 69 studies that used random assignment…

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 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 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 report systematically reviews research on the outcomes of programs that teach young children in a group setting before they begin kindergarten. Study inclusion criteria included the use of randomized or matched control groups, evidence of initial equality, and study duration of at least 12 weeks. Studies included valid measures of language,…

Describes the current state of evidence of effectiveness for replicable programs available to elementary and middle schools serving many students placed at risk, and provides Title I schools with information on the instructional outcomes of programs they might consider to meet student needs. Characteristics of programs identified as effective are…

This paper examines research on classroom programs for elementary school students who are at risk for learning problems. The full range of alternative classroom organization models designed to meet the needs of low-achieving or heterogeneous classes is explored in an attempt to discover which type of program is most effective and why. The goal of…

This article reviews research on the achievement outcomes of three types of approaches to improving elementary mathematics: Mathematics curricula, computer-assisted instruction (CAI), and instructional process programs. Study inclusion requirements included use of a randomized or matched control group, a study duration of 12 weeks, and achievement…

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…

Reviews 16 studies of 5 1-to-one tutoring models (Reading Recovery, Success for All, Prevention of Learning Disabilities, the Wallach Tutoring Program, and Programmed Tutorial Reading) used with at-risk first graders. Finds (1) substantial positive effects of tutoring; (2) effects of tutoring are generally lasting; and (3) results were more…

This paper discusses comprehensive school reform (CSR), which accepts the importance of standards and accountability but adds to these strategies for introducing innovations in curriculum, instruction, school organization, governance, parent interactions, and other core features of practice. The paper reviews research on the nature and quality of…
