Twenty-nine reports yielding 112 studies were analyzed with Glass's meta-analysis technique, and results were compared with predictions from Ausubel's model of assimilative learning. Overall, advance organizers were shown to be associated with increased learning and retention of material to be learned. (Author)

This paper focuses on interpreting the major conceptual features of California's Academic Performance Index (API) as a coherent set of statistical procedures. To facilitate a characterization of its statistical properties, the paper casts the index as a simple weighted average of the subjective worth of students' normative performance and presents…

This report summarizes the pattern of employment in education for women and minorities from colonial times to the present. Initially, women taught basic skills to young children, and men taught in secondary schools, academies, and colleges. By the 1900s, administration was seen as separate from teaching. Women were seen as better at understanding…

A meta-analysis was conducted to determine whether there were differences between the assigned academic achievement levels of students who were assessed with traditional methods of assessment and those who were assessed with alternative methods. From the more than 800 studies identified through literature searches, 7 studies, with a total of 5,020…

Four aspects related to self-esteem and academic achievement were addressed in the review. The first goal was to address methodological considerations of self-esteem measurement. Support for some self-esteem measures, as well as caveats and directions for future research, were indicated. The second goal was to determine whether a relationship…

Explores the interdisciplinary nature of interdisciplinary research, provides a brief explanation of the Integrative Review of Research of which meta-analysis can be a part, and describes the librarian's role, particularly in data collection. Discusses developing trends in the area, including the use of the World Wide Web. (Author/LRW)

Conducted a meta-analytic review of 41 studies to explore the relation between children's aggressive behavior and hostile attribution of intent to peers. Found a significant association between hostile attribution of intent and aggressive behavior, with larger effects associated with more severe aggressive behavior, rejection by peers as a…

Conducted a reliability generalization meta-analysis of subscale and total scale scores on the Web-administered LibQUAL+ (tm) (Cook and others, 2002), a measure of library service quality. Data for 18,161 participants from 43 universities show that score reliabilities are remarkably invariant across campuses and different over groups. (SLD)

Used meta-analytic techniques to compare men's and women's attitudes toward homosexual persons, homosexual behaviors, and gay people's civil rights. As expected, size of sex differences varied across these categories. Men were more negative than women toward homosexual persons and homosexual behavior, but the sexes viewed gay civil rights…

Two estimators of effect size that are based on the sample quartiles are proposed and studied. One is for the situation where a treatment effect is evaluated against a control group, and the other is for a situation in which two parallel treatments are compared. Both are illustrated and evaluated. (SLD)

A model is proposed to account for publication bias explicitly using a weight function that describes probability of publication for a particular study in terms of a selection parameter. A Bayesian analysis of this model using Gibbs sampling is conducted, and the model is applied to a published meta-analysis. (SLD)

A selection model for meta-analysis is proposed that models the selection process and corrects for the consequences of selection by publication on estimates of the mean and variance of the effect parameters. Simulation studies show that the model substantially reduces bias when the model specification is correct. (SLD)

Compares the usefulness of standard score results (such as correlations and standardized regression of coefficients) to that of raw scores results (such as covariances and raw score regression coefficients). Examines the two main advantages of presenting standardized results. Demonstrates the implications of these two standardized score advantages…

Relates the development of theories concerning gender differences in mental ability and reexamines them using meta-analysis. Finds that the greatest difference is in one type of spatial ability, mental rotation. There is only a small difference in mathematical performance, and no difference in verbal ability. (DM)

A meta-analysis compared quality of writing samples of 836 students (kindergarten through college) using word processors versus traditional writing methods. Study found small but significant improvement of quality of those using word processors; no significant difference between experienced and nonexperienced writers; small, significant positive…
