The purpose of this study was to determine the trends of recent research papers in foreign language teaching in Turkish context and to give ideas to researchers and policy makers for future studies. Content Analysis method was used in this study. The focus of the study was 189 research papers published between 2009-2013 years in journals indexed…

This report summarizes the complex research literature on quantitative methods for assessing how impacts of educational interventions on instructional practices and student learning differ across students, educators, and schools. It also provides technical guidance about the use and interpretation of these methods. The research topics addressed…

"Modern" statistics may generate more replicable characterizations of data because, at least in some respects the influence of more extreme and less representative scores are minimized. Explaining both trimmed and Winsorized (C. Winsor) statistics, this paper uses examples to show the effects concretely. Although the paper focuses on…

In my 15th and final year as JRRE editor, I identify methodological and substantive shortcomings in the rural education research literature and, in turn, suggest strategies for improvement. I structure my observations around the following considerations: describing the rural context of research, making the rural argument, framing the research…

Previous research has devoted a great deal of attention to describing the long-term patterns and relationships among trait-level or situation-specific variables. The present discussion extracts kernels of wisdom, based on the literatures on language anxiety and language learning motivation, that are used to frame the argument that choosing to…

Homogeneity of variance (HOV) is a major assumption underlying the validity of many parametric tests. More importantly, it serves as the null hypothesis in substantive studies that focus on cross- or within-group dispersion. Despite a widely acknowledged need for testing HOV, very few textbooks give adequate coverage on the topic, and many HOV…

This review of research literature focuses on studies using expertise methodologies outside of the laboratory for identifying differences and factors influencing high and low performance. Highlights include performance at the individual, process, or organizational level; statistical methods and techniques; and implications for performance…

Suppressor effects are considered one of the most elusive dynamics in the interpretation of statistical data. A suppressor variable has been defined as a predictor that has a zero correlation with the dependent variable while still, paradoxically, contributing to the predictive validity of the test battery (P. Horst, 1941). This paper explores the…

Critiques some of the strong positions taken by Bruce Thompson on a variety of methodological issues. Provides alternative views, and discusses the role of editorial policy in research reporting. Focuses on: (1) stepwise methods; (2) context specificity; (3) weights and structure coefficients; (4) reliability as a characteristic of scores and not…

This article focuses on Louis Guttman's contributions to the classical theory of educational and psychological tests, one of the lesser known of his many contributions to quantitative methods in the social sciences. Guttman's work in this field provided a rigorous mathematical basis for ideas that, for many decades after Spearman's initial work,…

Image studies, or imagology, was traditionally subsumed under the uncritical notion of "national character", which was itself replaced by the constructivist term "national stereotype". Since its origins in comparative literature, the field has moved beyond the narrow disciplinary confines of the humanities, with their predominantly qualitative…

Presents procedures for reducing attrition in clinical research and provides a case study for examination by researchers. Includes lists of preventative strategies and statistical methodologies to reduce attrition and bias. Argues that early planning for attrition by adjusting sample sizes is a scientifically sound approach to clinical research…

Describes the strengths and weaknesses of a new type of multivariate technique, covariance structure analysis (LISREL). Provides a detailed example which shows how the use of covariance structure analysis can improve research sophistication and theory development in counseling psychology. (Author/ABB)

Presents a literature review that covers the following topics related to data mining (DM) in health and medical information: the potential of DM in health and medicine; statistical methods; evaluation of methods; DM tools for health and medicine; inductive learning of symbolic rules; application of DM tools in diagnosis and prognosis; and…

Presents an overview of the literature on reference services for quantitative social research; differentiates between data for information and data for research; suggests a general approach to providing services for these materials based on traditional archives and government documents reference; and gives a practical framework for handling…
