A framework and concepts for developing inclusion criteria for meta-analysis are presented and illustrated in a meta-analysis of primary studies in patient education for preventive health services. Of 5,451 citations located and abstracts screened, 64 studies eventually met acceptability criteria. (SLD)

Discusses features of interpersonal conflict, defined in terms of oppositional behavior. A meta-analysis of research on conflict management indicated that adolescents' disagreements with close peers, in contrast to disagreements with parents or others, were managed in a manner that avoided disruption of the relationships. Characteristics of…

This paper reviews 27 studies of parental attitudes on the deinstitutionalization of a family member with disabilities. Studies of existing institutional placements found high levels of satisfaction and opposition to deinstitutionalization, whereas studies of community placements found high levels of satisfaction with community placements and…

This study used meta-analyses to evaluate the relative effectiveness of a variety of educational interventions with students who have disabilities. A graph of average effect sizes for 18 interventions shows the demonstrated effectiveness of mnemonic training, reading comprehension instruction, behavior modification, direct instruction,…

Finds that communication-skills instruction generates (using the Binomial Effect Size Display) a 44% increase in critical-thinking ability. Finds that forensic participation demonstrated the largest positive impact on critical-thinking improvement, but that all communication skills experiences demonstrated significant improvement. (SR)

Student ratings of instruction measure general instructional skill, give a composite of delivering instruction, facilitate interactions, and evaluate student learning. A meta-analysis of the multisection validity studies indicates student ratings are moderately valid, but affected by administrative, instructor, and course characteristics. (MMU)

Focuses on the evaluative use of teaching portfolios for personnel decisions in higher education and compares claims for their merits against fundamental research on evaluating faculty teaching. Draws on the literature on teaching portfolio development and suggests meta-analysis to examine the impact of using portfolios for personnel decisions.…

All 1999 issues of 26 journals in special education technology, special education, and educational technology were reviewed and 788 articles were identified of which 114 were judged as contributing to the knowledge base on special education technology research and practice. Four journals contained 60 percent of the relevant articles. Content…

Meta-analysis of 18 studies on the effectiveness of computer-assisted instruction (CAI) at the college level found an overall mean effect size of 0.127, i.e., students receiving traditional instruction supplemented with CAI performed slightly better than those receiving only traditional instruction. CAI was most effective in aviation and English…

Performed a meta-analysis of 22 wilderness challenge programs to assess impact on delinquent behavior. The overall effect size for delinquency outcomes (0.18) was equivalent to a recidivism rate of 29% for program participants versus 37% for nonparticipants. Greatest reductions in delinquent behavior came with intense physical activities or…

Analyzed 32 outcome studies on the primary prevention of adolescent pregnancy and examined several moderator variables in relationship to the findings. Results indicate that certain pregnancy prevention programs had no effect on adolescents' sexual activity. Found sufficient evidence to support the efficacy of pregnancy prevention programs for…

It is argued that, although thousands of evaluations have been conducted of social interventions, little has been done to cumulate those results to guide intervention architects. Building social intervention theory and meta analyses are suggested as ways to unify this knowledge and make it useful. (SLD)

Examines the scientific evidence supporting claims about phonemic awareness (PA) instruction. Presents a quantitative meta-analysis evaluating the effects of PA instruction on learning to read and spell. Concludes that PA instruction was found to make a statistically significant contribution to reading acquisition. (SG)

Cumulates findings across existing empirical research on the effects of violent video games to estimate overall effect size and discern important trends and moderating variables. Suggests there is a smaller effect of violent video games on aggression than has been found with television violence on aggression. (SG)

Presents a meta-analytic study based on the assumption that children's cognitive abilities can be both highly heritable and highly malleable. Results show strong support for the idea that early childhood education is a highly effective preventive intervention. Also finds that as preschool intervention intensity increases, so does the magnitude of…
