This special issue deals with the identification and remediation criteria/practices employed in several countries regarding learning disabilities (LD). An analysis of the identification criteria suggests that most countries follow early law mandates of the United States (e.g., PL 94-142) regarding the definition of the disorder and use the…

Using a set of scenarios derived from actual evaluation studies, this simulation study examines the reported influence of evaluation information on decision makers' potential actions.

The year 1998 marked 50 years of doctoral study in New Zealand, and in 1999 I embarked on a history of Ph.D. theses in Education. Influenced by Foucaultian genealogy, this employed a fusion of bibliographic, archival and life-history interview methods.

One of the major series of reviews in elementary and secondary education is the Best Evidence Encyclopedia, or the BEE. Up to now, findings for systematic reviews have largely been restricted to the reviews themselves, with few cases in which lessons learned across many reviews using similar methods can be synthesized. The completion of the Best…

This article systematically reviews research on the achievement outcomes of four types of approaches to improving the beginning reading success of children in kindergarten and first grade: Reading curricula, instructional technology, instructional process programs, and combinations of curricula and instructional process. Study inclusion criteria…

Most studies of mail survey methodology focus on specific design elements, but several major reviews of research have attempted to synthesize the findings of independent empirical studies. This study examined the review articles for what they have to say about factors influencing response rates and for their methodology. A literature review…

Analyses of the efficacy of group psychotherapy indicate that group therapy demonstrates, in a majority of reviews, significant improvement over inert comparison groups and proves comparable or superior to other active treatment conditions. Because group therapy is a viable cost-efficient treatment option being used with increasing regularity…

One approach to examining the findings of multiple studies is descriptive. This descriptive review of the research on increasing the response rates to mail surveys is based on studies also subjected to a meta-analysis. An initial narrative review identified the studies to be used in both analyses, and results will allow the possibility of…

A study quantitatively summarized the literature examining the association between acceptance of rape myths and exposure to pornography to address disputes in the academic community regarding the consistency of such research.

A search of the ERIC database and a review of the literature suggests that meta-analysis is ignored by philosophers, a situation that is regrettable but remediable. Meta-analysis is a method by which one attempts to integrate findings quantitatively from several research studies related to a common general topic. Philosophers should certainly pay…

This study used meta-analysis research techniques to determine if there are differences in General Aptitude Test Battery (GATB) validities and test scores between males and females. The sample consisted of 26,111 subjects from 122 Specific Aptitude Test Battery (SATB) validation or revalidation studies analyzed since 1972. Four approaches were…

The purpose of this paper is to review some of the methods used for the impact evaluation of Demonstrator-Developer projects and to promote the meta-analysis approach. Four examples of attempts to collect and analyze impact data from adopters are presented, one of which used the meta-analysis approach. In this example, each adopter collected pre…

An overview of the state of the art in psychological research is presented, with an emphasis on the attention given to effect sizes. The acceptance of small effect sizes for biomedical research is contrasted with the rejection of similar effect sizes for psychological research. The Binomial Effect Size Display is used to depict the practical…
