Because of the tremendous growth in college populations in the last 30 years, the number of programs designed to help underprepared students has grown significantly. Whether or not these programs work is still in question. This study used the meta-analysis techniques of Glas (1976) and Hedges (1985) to study a subset of developmental studies…

This paper compares the effects of desegregation on black achievement with the effects of other factors in the process of school learning that have recently been synthesized. The first section of the paper discusses techniques and guidelines for research synthesis, including meta-analysis. The second section presents a summary of the statistical…

This meta-analysis examines the effects of adventure programs on diverse outcomes such as self-concept, locus of control, and leadership. Analysis of 1,728 effect sizes from 96 studies shows that effect sizes varied substantially and improved as the length of the program and ages of the participants increased. (SLD)

Discusses the instructional effectiveness of various educational media, including illustrations; visual-based instructional media, including films, filmstrips, and television; programed learning; computer-assisted learning; audio-tutorial instruction; methods of group organization; and mastery learning methods. Research methodologies are also…

Recent meta-analysis of studies of computer-based education (CBE) assessed effects on student cognitive skills, academic achievement, and attitudes. CBE methods include drill-and-practice, simulation, and tutorials. Program guides and evaluation criteria are listed. Effectiveness of CBE varied with age, ability, and program type, and basic…

What is known about the cost effectiveness of interactive courseware (ICW) is reviewed, and issues that remain are summarized. Effect size is used for reporting the effectiveness of ICW programs. Two ICW media are considered: computer-based instruction and interactive videodisc instruction. Effect sizes for computer-based instruction have been…

The study reported in this paper quantitatively integrated the recent research findings on ability grouping in order to generalize about these effects on student achievement and student self-concept. Meta-analysis was used to statistically integrate the empirical data. The relationships among various experimental variables including grade level,…

The objective of this study was to evaluate quantitatively through meta analysis the effectiveness of child sexual-abuse prevention programs conducted over the past 10 years. Eighteen controlled studies evaluating such programs were coded for salient features and study outcomes and were then described using the common scale of effect size. An…

This paper analyzes 19 studies that were considered by the National Institute of Education's panel on the effects of school desegregation in order to determine desegregation's effect on black achievement, black self-esteem, and racial relations. It is stated that, overall, the results show that reading achievement improves somewhat as a result of…

A meta-analysis was conducted of 137 studies investigating the effects of father absence due to employment, military service, death, divorce, separation, or desertion on children's cognitive performance as assessed by scores on standardized intelligence, scholastic aptitude, and academic achievement tests and school grades. Aggregation of the…

Although school desegregation was initiated to address a social inequity--segregated schooling was seen as stigmatizing blacks as a social group--research has focused primarily on desegregation's effects on black academic achievement and self-esteem. Two problems have made this research difficult: the ambiguity of the term "school desegregation"…

A meta analysis was conducted of studies of college students' evaluations of their teachers. Forty-seven studies were included, representing 74 multisection courses, in which four selection criteria were met. An actual, rather than an experimental class was used; the unit of analysis was the class rather than the individual student; a common…
