The suspected sources of confounding in current meta-analytic studies of computer based instruction (CBI) are uncontrolled effects of instructional method and/or the John Henry Effect (i.e., compensatory rivalry). To determine which confounding is most plausible, a random 30% sample of the 128 studies which formed the original Kulik meta-analyses…

The 101 computer-based education (CBE) studies considered for use in this meta-analysis came from three major sources: references in an earlier meta-analytic review of CBE at the college level (J. Kulik, et al., 1980); a computer search of the Comprehensive Dissertation Abstracts and ERIC databases; and utilization of the bibliographies contained…

Analysis of 165 studies (representing the testing of 1,418,899 subjects) that reported data on gender differences in verbal ability indicated a slight female superiority in performance. The difference is so small that it appears that gender differences in verbal ability no longer exist. A major goal was also to define age trends in the pattern of…

To examine the effects of the language experience approach (LEA) on beginning reading achievement, a study analyzed five projects conducted as part of the United States Office of Education first grade studies and 32 additional studies comparing basal reading approaches to LEA. Using two methods of quantitative synthesis (vote-counting and…

This study examined the relationship among accountability, efficacy, and organizational effectiveness by integrating findings from 17 research and development reports on Management by Objectives (MBO), an intervention that incorporates elements and processes of both accountability (goal-setting, measuring and monitoring, feedback) and efficacy…

This paper summarizes and analyzes data from studies of differential validity and differential prediction for blacks versus whites and females versus males. Forty studies on racial differences and 53 on gender differences were selected from searches of the ERIC, PsychInfo, and Dissertation Abstracts International databases; Buros' Mental…

The 594 studies referenced in this volume, the first of a two-volume set, synthesize reading comprehension research conducted from 1974 to 1984. The 12 chapters cover the following topics: (1) the necessity for both quantitative and qualitative meta-analysis for a complete state-of-the-art understanding of any domain, (2) the background of the…

A meta-analysis of eight studies, involving 192 subjects, was performed to ascertain the efficacy of hospitalization of children with nonorganic failure to thrive. Hospitalization was found to approximately double the probability of catch-up physical growth for the children, but psychosocial development was only modestly hastened by…

The literature review organizes research of the National Technical Institute for the Deaf concerning characteristics of successfully mainstreamed hearing-impaired students in terms of: family background; previous educational experience; cognitive skills; motivation; speech, hearing, and communication skills; previous course grades, lecture…

The Carl D. Perkins Vocational and Applied Technology Education Amendments of 1998 extended support for "career guidance and academic counseling." A wide variety of such interventions are in existence. Since the No Child Left Behind Act of 2001 emphasizes evidence-based education, it is important to examine the research to determine the…

This report presents a meta-analysis of research on teaching expressive writing to students with learning disabilities. Virtually all the interventions analyzed were multifaceted and involved students writing everyday as part of the curriculum. The meta-analysis identified several themes critical to effective writing instruction: (1) adherence to…

There are about 80,000 public school principals in the United States today.

Numerous articles and studies written on the principal shortage conclude that qualified, experienced principals are getting harder to find,…

This volume on the identification of learning disabilities (LD) offers chapters that provide comprehensive reviews of the research evidence underlying different aspects of LD and was the product of a 2001 general conference followed up by a small research forum. Contributors include researchers, parents, practitioners, and administrators. A final…
