In the past two decades, numerous meta-analyses have been published that examine the question of psychotherapy equivalence. Hunsley and Di Giulio (2002) critically reviewed this literature and concluded that there was abundant evidence that the Dodo bird verdict of equivalence across psychotherapies is false. In this article, we summarize and…

The issue of the "research-practice gap"--the problematic relationship between research in education and educational practice--has been widely reported in the literature. This critical literature review explores some of the causes and features of the gap and suggests some possible approaches for addressing it. These solutions involve changes in…

The usefulness of meta-analysis in summarizing domains of primary research has led to widespread use of the techniques. Often, however, the researcher will have several options when cumulating empirical studies and readers will have questions regarding judgment calls made during a meta-analysis. In these cases, it is helpful to consult the primary…

This paper reviews meta-analysis procedures and several meta-analysis findings related to science teachings. Several generalizations are offered, one which indicates that instructional techniques which help students focus on learning (preinstructional strategies, increased structure in verbal content of materials, use of concrete objects) are…

A review of 287 references describing computer applications with deaf children found 74 percent concerned academic applications, 7 percent were psychological investigations, and 19 percent were about general education. Analysis of the academic instruction references found only 9 percent reported efficacy data with degree of computer-assisted…

The article reviews three studies (EC 600 064-066) evaluating the effectiveness of using Irlen tinted lenses or overlays with reading-disabled persons. It is concluded that carefully designed and controlled studies do not currently lend support to the Irlen hypothesis. (DB)

A meta-analysis of studies of the impact of new science curricula on the performance of students was initially conducted in 1983 as part of a coordinated program of meta-analysis of research on science education. This paper reports the results of a re-synthesis of the research dealing with student performance in the new science curriculum using…

This review examined the literature on peer tutoring in reading with students with disabilities, using the methodology of best evidence synthesis. This approach combines positive aspects of meta analysis with traditional integrative review procedures. It requires all studies reviewed to meet stringent a priori standards. Analysis of the 11 studies…

Methods for meta-analysis have evolved dramatically since Gene Glass first proposed the term in 1976. Since that time statistical and nonstatistical aspects of methodology for meta-analysis have been developing at a steady pace. This guide is an attempt to provide a practical introduction to rigorous procedures in the meta-analysis of social…

Differences in science achievement between males and females have been examined either directly or indirectly in a variety of studies. This investigation reviewed a quantitative synthesis of correlational research on science affect, ability, and achievement conducted by Steinkamp and Maehr. Their findings were reassessed by employing a…

Findings of 79 research reports were analyzed to assess the effects of calculators on student achievement and attitudes. Except in grade four, use of calculators in concert with traditional mathematics instruction improved average students' basic skills with paper and pencil, both in working exercises and in problem solving.

The National Early Literacy Panel (NELP) was appointed in 2002 and carried out its work under the auspices of the National Center for Family Literacy (NCFL). NELP's primary goal was to identify interventions, parenting activities, and instructional practices that promote the development of children's early literacy skills. The National Institute…

The great concern in recent decades over the trends of declining student achievement scores and increased cost of schooling has prompted speculation about how these trends might relate to one another. Much like popular opinion, research findings from studies of this relationship have often been contradictory. This study presents results from a…

Substantive and methodological problems encountered in a five-year synthesis of research on college impact are discussed, including general issues in higher education research and scholarship, relevance of assessments of student change, unnoticed indirect effects of college experience, inattention to individual differences, validity of common…
