A quantitative research synthesis (meta-analysis) was conducted on the literature concerning the effects of feedback on learning from computer-based instruction (CBI). Despite the widespread acceptance of feedback in computerized instruction, empirical support for particular types of feedback information has been inconsistent and contradictory.…

The Department of Administrative and Policy Studies (APS), University of Pittsburgh (Pennsylvania), completed six research reports about its Conceptual Mapping Project. The reports reproduced here originally appeared in the "Occasional Paper Series" of the APS. They are presented in order of the chronological appearance as follows: (1)…

H. M. Cooper (1988) has developed a taxonomy that classified literature reviews based on six characteristics: (1) focus of attention; (2) goal of the synthesis; (3) perspective on the literature; (4) coverage of the literature; (5) organization of the perspective; and (6) intended audience. One hundred and three meta-analyses identified from the…

Five interrelated papers that explore the theme of validity within the context of cross-national assessments are grouped in this collection. These papers were presented at a symposium at the annual meeting of the American Educational Research Association. These papers draw on data from the Third International Mathematics and Science Study (TIMSS).…

The usefulness of the Cognitive Engagement in Cooperative Learning (CECL) model for evaluating the learning outcomes associated with various cooperative learning activities is explored. The instructions that a set of learners is given, however broad or specific, is called a script. These scripts are associated with different learning outcomes…

This literature review examines whether verifiable evidence supports the supposition that early interventions result in better child developmental outcomes than later interventions for disadvantaged children with disabilities. First, existing reviews of the literature on the "earlier is better" supposition were examined. Second, a meta analysis on…

Meta-analysis is a collection of systematic techniques for resolving apparent contradictions in research findings. Meta-analysts translate results from different studies to a common metric and statistically explore the relations between study characteristics and findings. Since G. Glass first used the term "meta-analysis" in 1976, it has…

The current legal standing of homosexual parents seeking custody of their children remains precarious. Courts determine custody and visitation on the basis of the "best interests of the child." Current judicial rulings reflect a bias against awarding custody or granting visitation rights to homosexual parents, favoring the heterosexual…

Few reliable data exist to provide an accurate estimate of the money invested in staff development or inservice programs in the United States for elementary and secondary school personnel. There are, however, some indicators by which costs of staff development programs at the federal level can be inferred. The problem of accurately gauging staff…

This metaanalysis examined different parental variables in order to determine which best predict children's externalizing behavior. Also examined were other variables that may influence the association of parenting and externalizing, such as type of child behavior, gender of parent and child, and age of child. Parental variables included in the…

The affect/effect theory of the mediation of teacher expectation effects is presented, and a research agenda is suggested for the investigation of this theory. In addition, some methodological issues in psychology are reviewed. The affect/effect theory states that a change in the level of expectations held by a teacher for the intellectual…

A review of literature on class size is the purpose of this report. Included are a summary of four meta analyses (Robinson and Wittebols 1986), (Cone 1978), and (Glass and Smith 1978 and 1979); a discussion of research methodologies; recommendations for policy makers; and alternative strategies for class size reduction. Appendices present…

A study reviewed 88 doctoral dissertations written during a 4-year period in the 1980s on the use of feedback for performance improvement. The purpose was to sugget applications of the findings to teaching improvement in postsecondary education, and to determine the extent to which faculty development centers contribute to this research.…

The educational effects of frequent classroom testing have been studied and discussed since the early part of this century. Many possible reasons for its presumed benefits have been offered, such as increased practice, review, improved course organization, and frequent opportunities for feedback. However, reviewers of evaluations of frequent…

This meta-analysis investigates the effects on achievement of type of graphing paper employed in displaying student performance data collected over time. Ongoing curriculum-based measurement systems employing Data-Based Program Development (DBPD) provide a data source of 16 controlled studies with 17 effect sizes. A total of 3,494 subjects…
