Reviews sources of indirect evidence supporting the value of graduate training in psychotherapy. Discusses training protocols that are known to enhance trainees' skills and summarizes a meta-analysis of therapy outcome studies involving within-study comparisons of psychotherapists of different levels of training and experience. Other research is…

Substantive and methodological problems encountered in a five-year synthesis of research on college impact are discussed, including general issues in higher education research and scholarship, relevance of assessments of student change, unnoticed indirect effects of college experience, inattention to individual differences, validity of common…

Reports the results of a meta-analysis that integrates research on undergraduate science, mathematics, engineering, and technology education since 1980. The meta-analysis of 39 studies demonstrates that various forms of small-group learning promote achievement, improve attitudes toward learning, and increase persistence in these fields. Contains…

An integrating framework to explain the research process was presented in the first edition of this book. This edition, which brings the material up to date, is designed to serve the Master s level student better while still meeting the needs of doctoral students of educational research. The nature of research, methods for qualitative and…

A meta-analysis of studies that have explored the effect of financial aid to undergraduates on persistence was undertaken. In addition to identifying such studies, research objectives were: to determine the magnitude of the effect of financial aid on student persistence in each study; and to compare the financial aid effect sizes in relation to…

The 101 computer-based education (CBE) studies considered for use in this meta-analysis came from three major sources: references in an earlier meta-analytic review of CBE at the college level (J. Kulik, et al., 1980); a computer search of the Comprehensive Dissertation Abstracts and ERIC databases; and utilization of the bibliographies contained…

There are about 80,000 public school principals in the United States today. The Bureau of Labor Statistics estimates a 10 percent employment increase in educational administration jobs between now and 2008. Numerous articles and studies written on the principal shortage conclude that qualified, experienced principals are getting harder to find,…

Primary research on student ratings of instruction is reviewed, and questions about the validity of such ratings as measures of teacher effectiveness are explored using nomological coding of 43 validity studies to examine causes of variability in coefficients of validity. Deficiencies of prior analyses and research needs are identified. (SLD)

Quantitative research on feedback that college teachers receive from student ratings is methodologically critiqued. The critique is based on a recently completed review and statistical study of 28 related studies by R. L'Hommedieu, R. J. Menges, and K. T. Brinko. Feedback effects may be stronger than research indicates. (SLD)

Describes results of a meta-analysis that was performed to synthesize existing research on the effects of computer programing on cognitive outcomes. Effect size is used to evaluate studies that used experimental and control groups to assess the relationship between computer programing and cognitive skills, and outcome measures are discussed. (79…

In its examination of the place of didactics in Scandinavian curricula, this paper discusses didactics as theory and prescription, at different levels of abstraction, and as scientific discipline. It focuses on the process of curriculum planning and selection in two areas: (1) preparing curriculum programs for teaching and learning nationally and…

The second of four symposium papers brings together the results of four separate statistical analyses of findings on computer-based instruction (CBI) in 199 comparative studies, of which 32 were conducted in elementary schools, 42 in high schools, 101 in universities and colleges, and 24 in adult education settings. Each was a controlled,…

Reflecting changes in the focus and methodology of writing research over the past 20 years, this book provides a meta-analysis of studies on teaching approaches and focuses on composition instruction at the elementary, secondary, and college levels. The first chapter of the book examines general studies of the composing process, studies of process…

This paper quantitatively analyzes the incidence of public education spending on the poor in developing countries by using the results of standard benefit-incidence studies and additional national data. Although there is considerable variation across studies, it is found that public education spending generally does not favor the poor, but it does…
