Over the past 15 years, we have seen an increase in the use of cluster randomized trials (CRTs) to test the efficacy of educational interventions. These studies are often designed with the goal of determining whether a program works, or answering the what works question. Recently, the goals of these studies expanded to include for whom and under…

Pupil Premium funding has been provided to schools in England since 2011, to help overcome socio-economic segregation between schools, and reduce the poverty attainment gap. Yet there is little evidence such an approach is effective. Some important stakeholders are considering whether Pupil Premium should stop or be re-routed. It is therefore…

In the past few decades, we have seen a rapid proliferation in the use of quasi-experimental research designs in education research. This trend, stemming in part from the "credibility revolution" in the social sciences, particularly economics, is notable along with the increasing use of randomized controlled trials in the strive toward…

The report of the national response to intervention (RTI) evaluation study, conducted during 2011-2012, was released in November 2015. Anyone who has read the lengthy report can attest to its complexity and the design used in the study. Both these factors can influence the interpretation of the results from this evaluation. In this commentary, we…

An effect size of about 0.70 (or 0.40-0.70) is often claimed for the efficacy of formative assessment, but is not supported by the existing research base. More than 300 studies that appeared to address the efficacy of formative assessment in grades K-12 were reviewed. Many of the studies had severely flawed research designs yielding…

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…

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…

The review examines evaluations of the efficacy of special education programs for mildly disabled children. The author suggests that serious methodological flaws make our present knowledge in this area very weak and proposes a methodology to address and overcome many of the limitations of previous research.

The article presents a critical overview of research on the integration of moderately mentally handicapped children in Ontario schools. Findings suggest that the literature is still inconclusive or, at best, equivocal. Indeed, like their predecessors, recent studies have been based, for the most part, on descriptive or impressionistic evidence.…

Professional literature extols the potential benefits of portfolios for teaching, learning, and assessment--particularly compared with traditional multiple-choice tests. Although initial findings favor portfolio assessments, the challenges lie in ensuring technical quality, equity, and feasibility for large-scale assessment purposes. Two major…

Asks why critical approaches to educational administration have rarely moved beyond critique to transformative process. This failure may stem from critical research's incompatibility with motivating and sustaining a complex change process. This article reviews two phases of critical research in education, identifies features enhancing research…

A California teacher in a successful Structured English Program criticizes Keith Baker's November 1998 article's inaccuracies. Baker fails to recognize that gains of immersion and early-exit students in David Ramirez's study are not sustained over time. Also, he erroneously compares study results of defined and ill-defined programs. (MLH)

Of the four guides to schoolwide reform models (by Herman and others, Northwest Regional Education Laboratory, Robert Slavin, and Margaret Wang and associates), Herman's volume provides the most detailed, scholarly review. Practical information abounds, but more well-controlled and designed longitudinal studies are essential. (Contains 32…

School-effectiveness research has made three considerable contributions: establishing a field exhibiting the characteristics of normal science, generation of research findings on numerous important topics, and combating of social/professional pessimism concerning educational-advancement prospects. School-effectiveness researchers will probably…

The position is taken that the effectiveness of bilingual education programs has not been adequately researched or evaluated. The lack of appropriate critical, empirical, or longitudinal studies is attributed to several factors. (MH)
