Discusses the effects of sampling scheme selection on the admissibility of log-linear models for multinomial and product multinomial sampling schemes for prospective and retrospective sampling. Notes that in multinomial sampling, marginal frequencies are not fixed, whereas for product multinomial sampling, uni- or multidimensional frequencies are…

Describes the history and current status of qualitative research in science education research. Discusses the issue of the quality of research. (JRH)

The purpose of this article is to critically examine some stated discrepancies between qualitative and quantitative research by taking actual studies as a starting point. It is argued that in ordinary empirical research within psychology and education, both approaches should be considered based on critical realism, and that the ordinary validity…

In a recent article in this journal, Lombard, Snyder-Duch, and Bracken (2002) surveyed 200 content analyses for their reporting of reliability tests, compared the virtues and drawbacks of five popular reliability measures, and proposed guidelines and standards for their use. Their discussion revealed that numerous misconceptions circulate in the…

This article discusses the dearth of qualitative and quantitative research in "Religious Education." There is a growing concern in educational journals that the field must respond to the needs of practitioners and publish what has been called "really useful knowledge" (Johnson 1988, 21-22). In "Religious Education," 86.5% of the published articles…

In their meta-analysis of clinical versus statistical prediction models, Aegisdottir et al. (this issue) extended previous findings of statistical-method superiority across such variables as clinicians' experience and familiarity with data. In this reaction, the authors are particularly interested in violence prediction, which yields the greatest…

This paper assesses the value of research, not on its methodology type but on its goal and accomplishments. It outlines an idea for developing a knowledge base capable of informing teacher education program planning and other educational policy decisions. Studies are described that advance knowledge about causal relationships between classroom…

Qualitative and quantitative social science research methods rather than representing opposing research methods instead are reinforcing research traditions. The ability of either research methodology to make lasting and important contributions requires the ability to synthesize and integrate with the other approach. While the assumptions of each…

The author contends that model misspecification can occur even after researchers have selected the generally most appropriate class of methods, or general linear model techniques. It is suggested specifically that canonical correlation analysis may provide more meaningful results, as compared with regression, particularly if analysis is augmented…

This paper addresses several issues in quantitative research that educational researchers should examine with more care. While the purposes of experimentation is to determine causality, the study of causal relations is difficult and problematic. Computational and conceptual errors in statistical analysis seem limited only by the creativity of the…

After the terms "qualitative research" and "quantitative research" are defined, this paper considers why it makes sense to integrate these approaches, at least under some circumstances. This discussion necessitates attention to the issue of whether quantitative and qualitative research are inextricably linked to incompatible…

The role of the coauthor relationship in the structure of informal communications networks within disciplines is explored, and the validity of coauthor graphs used to map these relationships is tested for both small and large databases. (CLB)

Presents observations of a researcher on state of educational research. States that some issues and questions have not changed in 50 years. Cites the arguments over the difference between basic and applied research, and the hereditary basis of intelligence. Concludes with remarks about inappropriate data analysis, the use of technology, and the…

The review of some recent studies on use of microcomputers in early childhood special education highlights methodological issues including the qualitative quantitative distinction and the interdependence of research design and interpretation. Imbedding qualitative methods into quasi- or true-experimental designs can provide more information than…

Defines structural equation modeling (SEM) and points out its relation to other more familiar data-analytic techniques, as well as some of the potentials and pitfalls of SEM in the analysis of developmental data. Discussion focuses on causal modeling, path diagrams, ordinary least-squares regression analysis, and powerful methods for model…
