It is a healthy exercise to debate the merits of using effect-size benchmarks to interpret research findings. However, these debates obscure a more central insight that emerges from empirical distributions of effect-size estimates in the literature: Efforts to improve education often fail to move the needle. I find that 36% of effect sizes from…

The authors of this position paper argue that there is currently very little evidence-based practice in relation to learners with severe learning disabilities (SLD) and profound and multiple learning disabilities (PMLD), and that which there is, has often been badly used and/or abused. More specifically, we argue that relevant educational research…

In 2012, Keith Curry Lance and his associates completed a second school library impact study in Pennsylvania. The research conducted in Pennsylvania was the result of an Institute of Museums and Library Services (IMLS) National Leadership grant that examined students' reading and writing scores with sub-groups of students (Hispanic, Black,…

The essay examines the variety of research methods and measures used in the first-year experience and students-in-transition field over the past 25 years. Interrogating the extant research, Kinzie explores whether the methods and analytic processes most commonly employed are adequate to advance our understanding of complex issues in the field. The…

The U. S. Department of Education has adopted using data for school improvement as one of its major education reform priorities. However, as states, districts, and schools develop new approaches to track academic progress, both accessing and understanding data are often out of reach for average parents. While school leaders and teachers have begun…

This study examines what specific data college faculty and administrators use in their jobs and the extent to which they use data analysis to design and improve the impact of programs and services. The study is based on a survey on the use of student data by faculty and administrators at 41 community colleges participating in Achieving the Dream:…

This report is designed to help policymakers, parents, reporters, and foundation officials better understand what has been learned about voucher programs and why some key questions remain unsettled. It is based on an analysis of voucher programs in Milwaukee, Cleveland, and Florida State. Four basic questions are addressed: (1) What do we know…

Over the past few years Research Data Services (RDS), part of the National Foundation for Educational Research (NFER), has led numerous large-scale, longitudinal projects. Feedback to schools has been provided for all of these projects, and has been in the form of sets of tables and charts and electronic files illustrating pupil performance and…

This report, the Center on Education Policy's (CEP's) third annual review of Maryland's efforts to restructure schools under the No Child Left Behind Act, finds that (1) although between school years 2006-07 and 2007-08 the number of schools in the restructuring implementation phase declined slightly, there was a drastic increase in the number of…

Social science research suggests that reducing class size has its largest effects on the achievement of minority and inner-city children during the first year of formal schooling. Despite scholarly disagreements about the implications of specific studies on class size, economists generally agree that targeted class-size policies rest on stronger…

This newsletter presents a critical view of some of the perils of translating research findings into classroom practice without careful examination of the human dimensions involved. The first issue discussed is ability grouping; it is pointed out that this practice does not necessarily increase academic achievement, particularly in the lower level…

Five research studies dealing with spelling achievement in New Zealand schools have been conducted; these include dictated-word spelling tests, written language studies, and achievement data collections of 20,000 students. Several conclusions emerge from an examination of this research: spelling achievement studies should be based on samples of…

Identifies trends in educational achievement in the 1970s. Presents hypotheses concerning the relationship between research and gains/declines in educational achievement during that period. Discusses a project for individualized learning programs and its theoretical rationale, and describes a research project based on that educational improvement…

Research for Better Schools (RBS) is supporting improvement efforts in Delaware, New Jersey, and Pennsylvania. One form of this support is RBS's participation in collaborative projects to develop a system-wide, research-utilization approach to the improvement of basic skills instruction. Educational systems following the approach employ a staff…

Reviews Tennessee's Project Student/Teacher Achievement Ratio (STAR) and puts the results in the context of other nonexperimental evidence about class size. Nonexperimental evidence does not support any achievement gains attributable to class-size reduction, and empirical evidence from STAR has design and implementation flaws that cast doubt on…
