This study aims to introduce network meta-analysis (NMA) to provide educational researchers with an extended view of the reviewing educational research. Meta-analytic methods have been widely used in educational research reviews. However, weaknesses have emerged in the multi-group comparison analysis of educational studies where different…

In several subdomains of the social, behavioral, health, and human sciences, research questions are increasingly answered through mixed methods studies, combining qualitative and quantitative evidence and research elements. Accordingly, the importance of including those primary mixed methods research articles in systematic reviews grows. It is…

Too many practitioners interpret ABAB research based on visual inspection rather than statistical analysis. Based on an experiment using cooperative learning to mainstream autistic students, hypothetical data for one student from an ABAB reversal design are used to illustrate the techniques and importance of regression analyses. Discussion focuses…

Highlights effective graphical methods for screening and cleaning data, exploring and identifying models, and displaying data in counseling-psychology publications. Argues that graphs are not ancillary to scientific publications but are essential and, in some cases, sufficient expositions of results. (Author/GCP)

The use of messages as experimental stimuli brings with it problems regarding the interpretability and generalizability of findings. Some psychologists and communication researchers have argued that message stimuli must be treated as random effects. A review of the literature examined data regarding experimental designs used in recent…

Presents an opinion on the appropriate use of significance tests, especially in the context of regression analysis, the most commonly encountered statistical technique in education and related disciplines. Briefly discusses the appropriate use of power analysis. Contains 47 references. (Author/SV)

Problems in current special education categorical research practices are discussed in terms of consistency and reliability, student heterogeneity, and lack of distinct categorical groups. Suggested changes include characteristic-oriented categorization, corresponding changes in dissemination of research findings, and greater specificity and…

Describes a series of 16 longitudinal studies conducted by Utah State University on alternative early intervention programs for disabled children, focusing on the intensity of intervention, the age intervention begins, and parent involvement. Reviews factors that gave rise to the studies, research designs and procedures, and data interpretation.…

This article discusses alternative analyses that reflect the practical significance of test results and the role of sample size in the interpretation of results. It explores effect size reporting and using "what if" analyses to reflect on the role of sample size in the decision to accept the null hypothesis. (Contains references.) (Author/CR)

Discusses logic and interpretation problems inherent in doing quantitative syntheses of single-case research. Addresses the meta-analytic method of using percentage of nonoverlapping data, highlighting special concerns related to withdrawal designs, sensitivity to variability in behavior, social significance of behavior change, and variables that…

This paper evaluates the logic underlying various criticisms of statistical significance testing and makes specific recommendations for scientific and editorial practice that might better increase the knowledge base. Reliance on the traditional hypothesis testing model has led to a major bias against nonsignificant results and to misinterpretation…

Highlights issues and controversies concerning current race-related educational research. Contends that some critics believe research sacrifices empirical objectivity for political goals. Partisan research supporters respond that all research begins with untested assumptions and an acknowledgment of purpose does not signify a skewed methodology.…

In November 1992, the Ford Foundation published a study entitled "State Higher Education Systems and College Completion," which argued that states that relied heavily on community colleges in their postsecondary educational system, such as California, Florida, Illinois, Indiana, and Wisconsin, were not efficient in producing bachelor degree (BA)…

This study examines some of the literature on college faculty supply and demand and asks whether it is possible to adopt assumptions from the previous research to construct a complex model of faculty workforce using the available data. The study involved a comprehensive review of the literature; numerous interviews conducted by telephone, e-mail,…
