Reviews studies of singing which used elementary-aged subjects over the past 25 years. Summarizes studies done on the singing inaccuracies of children, and reviews studies on the processes required for accurate singing. Presents studies on factors affecting children's singing and examines the implications of this research for singing education.…

Meta analysis techniques were used to synthesize research on teaching students how to control variables when designing an experiment. The review included 65 controlled studies. Findings are reported in terms of the influence on effect sizes of characteristics of the study, instruments used, treatments applied, and results' utilities. (SLD)

Meta-analytic techniques tested the effect on learning of the interaction of prior achievement with instructional support. This review of nine studies indicates that differences in prior achievement levels can be reduced through instructional treatment. Results support the use of meta-analyses for other investigations of aptitude-treatment…

Discussion of the effects of instruction on the attitudes of nurses focuses on a meta analysis of studies that examined effects of visual media in attitude formation or attitude change in nursing education. Criteria used to guide the selection of studies included are explained, and implications for instructional design are discussed. (76…

Used meta-analysis to review 33 evaluations of school-based alcohol and drug education programs. Found typical substance abuse education had most positive effects on knowledge and attitudes, but was unsuccessful in changing drug-using behaviors of students. Attitudinal effects were significantly higher when peers were instructional leaders and…

Provides a comprehensive summary of research literature on the accuracy of proxy reports of parental status characteristics. Tests four hypotheses in relation to the influence of the child-respondent's age, race, and gender and the parents' education or occupation on the accuracy of reporting. (LS/Author)

Thirty-five studies on the efficacy of special class versus regular class placement for mildly handicapped students were reviewed for the power of their statistical tests. Twenty-one studies had adequate power to detect a large effect size but the power to detect a medium effect size was no better than chance. (Author/DB)

An analysis of 47 nursing research studies from 1981-90 related to predicting student success was conducted. Grade point average in nursing and science courses was the greatest cognitive predictor, parental education and age the greatest demographic predictors. Meta-analysis of four studies showed the significant effectiveness of interventions…

Analysis of studies on predictors of people's attitudes toward gifted education reveals that about 50 variables have been examined as potential sources of differences, but not a single variable emerges as a substantial explanatory factor. Major methodological problems in the studies are identified and proposals for future research are offered.…

Analyzes attachment theory's viability as an overarching framework for counseling psychology. Places particular emphasis on the integrative potential and heuristic value of the theory, arguing that it can use biological (structural), psychological (cognitive/affective), and social dimensions of experience to clarify developmental dynamics in…

Outlines the current debate regarding the veracity of delayed memories of child sexual abuse, describes the historical context in which this controversy occurs, discusses the growth and development of psychotherapy for trauma survivors, and reviews the theoretical and empirical literature relevant to abuse memories. Presents recommendations for…

Reports the findings of victim interviews and archival data concerning incidents of woman abuse. Results for samples monitored over a 6- to 12-month period supported the use of arrest on first police visits to the home and subsequent action by the courts, including ordering perpetrators into treatment. (RJM)

Effects of using different combinations of internal and external matching variables were examined using a generalized Mantel-Haenszel statistic, a technique based on meta-analysis, and logistic discriminant function analysis with data from a writing assessment for over 4,200 8th graders. Results did not support use of an external matching…

The use of statistical methods to combine the results of independent empirical research studies (metanalysis) has a long history, with work mainly divided into tests of the statistical significance of combined results and methods for combining estimates across studies. Methods of metanalysis and their applications are reviewed. (SLD)

Meta-analysis of 143 effect sizes in 43 studies of adventure programming for adolescents found an overall effect size of 0.31. Summary effect sizes of outcome categories differed significantly among categories, however. Effect size was related to program length and participant age but not to delinquent status. Discusses the lack of pertinent…
