The evidence base for educational interventions for deaf students has been, and continues to be, called into question due to a lack of "gold standard" research available to support it. Yet the paucity of research in deaf education is not only in the volume of research that meets rigorous standards but also in its lack of attention to and…

The attempts to evaluate the published postgraduate theses aiming to research the Social Studies curriculum in Turkey between the years of 2015-2020. The study adopted general survey model. The study consisted of 866 open access theses which were conducted on the Social Studies curriculum between 2015-2020, and which were obtained from Council of…

University league tables give the image that there is a single dimension along which institutions can be placed. Most derive rankings from an aggregate score of multiple items, which often include opinion responses which has the potential to introduce sampling bias. This paper explores what happens when the two issues of dimensionality and…

In this study, it was aimed to examine the postgraduate theses and articles on ethical leadership in Turkey by gathering them through the document analysis method and by using content analysis. In this direction, all of the postgraduate theses and articles that can be accessed in the electronic environment as a full-text were included in the scope…

Researchers and policymakers in the US and beyond increasingly seek to identify teaching qualities that are associated with academic achievement gains for K-12 students through effectiveness studies. Yet teaching quality varies with academic content and social contexts, involves multiple participants, and requires a range of skills, knowledge, and…

Successful testing programs rely on high-quality test items to produce reliable scores and defensible exams. However, determining what statistical screening criteria are most appropriate to support these goals can be daunting. This study describes and demonstrates cost-benefit analysis as an empirical approach to determining appropriate screening…

In the study, it was aimed to examine theses written on value education between 2009 and 2019 in terms of descriptive and methodological features. In this context, 475 theses, which were written between the relevant years and have access, were reached. Within the scope of the research, the criterion-sampling method was used while determining…

Structured means analysis is a very useful approach for testing hypotheses about population means on latent constructs. In such models, a z test is most commonly used for testing the statistical significance of the relevant parameter estimates or of the differences between parameter estimates, where a z value is computed based on the asymptotic…

This article addresses the problem of estimating the proportion Pi[subscript S] of the population belonging to a sensitive group using optional randomized response technique in stratified sampling based on Mangat model that has proportional and Neyman allocation and larger gain in efficiency. Numerically, it is found that the suggested model is…

The variance formula derived for a two-stage sampling design without replacement employs the joint inclusion probabilities in the first-stage selection of clusters. One of the difficulties encountered in data analysis is the lack of information about such joint inclusion probabilities. One way to solve this issue is by applying Hájek's…

This Workshop on Survey Methods in Education Research tool consists of a facilitator guide and workshop handouts. The toolkit is intended for use by state or district education leaders and others who want to conduct training on developing and administering surveys. The facilitator guide provides materials related to various phases of the survey…

This paper provides a critical review of indicators that can be used to measure equity in educational outcomes. These indicators are evaluated using different criteria. Further, analysis on how the sample structure affects equity measurements is undertaken. Analyses are based on theoretical reasoning and empirical data from the German National…

Racial/ethnic educational disparities remain a pervasive and intractable issue facing the U.S. education system. To eliminate these disparities, educational research must consistently attend to race/ethnicity, particularly when examining the effects of educational practices, programs, and policies. The goal of the current review was to examine the…

Confidence intervals for effect sizes (CIES) provide readers with an estimate of the strength of a reported statistic as well as the relative precision of the point estimate. These statistics offer more information and context than null hypothesis statistic testing. Although confidence intervals have been recommended by scholars for many years,…

Most study samples show less variability in key variables than do their source populations due most often to indirect selection into study participation associated with a wide range of personal and circumstantial characteristics. Formulas exist to correct the distortions of population-level correlations created. Formula accuracy has been tested…
