This study introduces an order-constrained Bayes inference framework useful for analyzing data containing dichotomous scored item responses, under the assumptions of either the monotone homogeneity model or the double monotonicity model of nonparametric item response theory (NIRT). The framework involves the implementation of Gibbs sampling to…

To investigate the process through which the educational research community can become more vibrant and cohesive, the authors of this article ask: How can the numerous networks that constitute the field of educational research be analyzed in an effort to understand and influence the pattern through which knowledge of educational phenomena are…

Although there are many methods available for dimensionality assessment for items with monotone item response functions, there are few methods available for unfolding item response theory models. In this study, a modification of Yen's Q3 statistic is proposed for the case of these nonmonotone item response models. Through a simulation study, the…

Data from international comparative studies in education are generally derived from complex, multi-stage sample designs and rotated assessments. Consequently, care must be taken not only in estimating variance components but also in interpreting them. Target population definitions, the nature of the sampling stages and their sampling units, and…

After extinction of fear to a Pavlovian conditional stimulus (CS), contextual stimuli come to regulate the expression of fear to that CS. There is growing evidence that the context dependence of memory retrieval after extinction involves the hippocampus. In the present experiment, we examine whether hippocampal involvement in memory retrieval…

This introduction sets the stage for the themed issue. It describes the ambiguities inherent in the interpretation of the literature on compositional and peer effects and the genesis of the project. The balance of the introduction then describes the approach adopted to search for peer effects. First, there is a brief outline of the Barr and…

Purpose: This paper aims to examine employees' conceptions of the meaning of experience in job-competence and its development in workplace context. The aim is to bring out the variety of conceptions related to experience, competence and workplace learning. Design/methodology/approach: The paper is based on interview data from six Finnish small and…

Based upon the lessons learned and the educational materials generated from a doctoral course on qualitative data analysis, a group of doctoral students, their professor, and a linguistics consultant launched an on-going project to create a series of reusable learning objects designed to help other groups of students and professors learn how to…

This article presents a model of data-based decision making based on five commonly used models from both within and outside the discipline of school counseling. This integrative model is tied explicitly to the ASCA National Model[R] concepts, terminology, and resources. It provides school counselors with a sequence to follow for engaging in…

The authors designed this study to understand how adolescents overcome suicidality from the subjective perspective of 13 previously suicidal female participants. A resilience framework was used to conceptualize the process. Data analysis using basic interpretive qualitative inquiry revealed 4 domains of resilience: social processes, emotional…

Cross-classified random effects modeling (CCREM) is used to model multilevel data from nonhierarchical contexts. These models are widely discussed but infrequently used in social science research. Because little research exists assessing when it is necessary to use CCREM, 2 studies were conducted. A real data set with a cross-classified structure…

Using the cluster generation procedure proposed by D. Steinley and R. Henson (2005), the author investigated the performance of K-means clustering under the following scenarios: (a) different probabilities of cluster overlap; (b) different types of cluster overlap; (c) varying samples sizes, clusters, and dimensions; (d) different multivariate…

An interview protocol based on V. Cass's (1979) sexual identity formation work was used with 13 self-identified lesbians. Data analysis yielded a sexual identity formation model similar to J. E. Marcia's (1966, 1987) identity development model. Potential emotional and physical health risks for each phase of the model are discussed, and…

A study to present specific hypothesis that satisfactorily explain the boiling point of a number of molecules, CH[subscript w]F[subscript x]Cl[subscript y]Br[subscript z] having similar structure, and then analyze the model with the help of multiple linear regression (MLR), a data analysis tool. The MLR analysis was useful in selecting the…

The goal of teaching technology used in every field of daily life as well as in every stage of education, is to have individuals acquire the necessary skills in technology use. In this era, these skills are among the essentials for individuals to discover the world with the help of technology. This study was carried out on students who completed…
