Interest in developing computerized adaptive testing (CAT) under cognitive diagnosis models (CDMs) has increased recently. CAT algorithms that use a fixed-length termination rule frequently lead to different degrees of measurement precision for different examinees. Fixed precision, in which the examinees receive the same degree of measurement…

This study compares four item selection criteria for a two-category computerized classification testing: (1) Fisher information (FI), (2) Kullback-Leibler information (KLI), (3) weighted log-odds ratio (WLOR), and (4) mutual information (MI), with respect to the efficiency and accuracy of classification decision using the sequential probability…

When tests consist of multiple-choice and constructed-response items, researchers are confronted with the question of which item response theory (IRT) model combination will appropriately represent the data collected from these mixed-format tests. This simulation study examined the performance of six model selection criteria, including the…

Recently, there has been an increasing emphasis in discussions on science education on the potential and advantages of stories and narratives in teaching situations. From this, one might conclude that simply starting to use stories in science classrooms is a good thing, "per se". Yet, as I will argue in my paper, things do not appear to be that…

A 2-way clustering approach to multiple correspondence analysis is proposed to account for cluster-level heterogeneity of both respondents and variable categories in multivariate categorical data. Specifically, in the proposed method, multiple correspondence analysis is combined with k-means in a unified framework in which "k"-means is…

Making one's own learning choices is central to self-directed learning, yet the opportunity to choose learning activities is rarely given to students in formal educational settings. The case study reported in this paper is a description of student experiences and perceptions in a software tools graduate level class that offered substantial…

Using a novel variant of dichotic selective listening, we examined the control of auditory selective attention. In our task, subjects had to respond selectively to one of two simultaneously presented auditory stimuli (number words), always spoken by a female and a male speaker, by performing a numerical size categorization. The gender of the…

Research on students' social relationships shows their preference to associate with similar peers. This study focused on the similarity in selection criteria used by students to form groups and similarity of characteristics of existing groups in schools. It compared these criteria to those of isolated students. The sample consisted of 124 students…

Data from 64 adolescent inpatients admitted for serious suicidal ideation, 50 adolescent inpatients admitted following a suicide attempt, and 56 randomly selected high school control participants were used to evaluate the sensitivity, specificity, positive predictive value, and negative predictive value of the Suicidal Ideation Questionnaire (SIQ)…

Application of Bayesian item selection criteria in computerized adaptive testing might result in improvement of bias and MSE of the ability estimates. The question remains how to apply Bayesian item selection criteria in the context of constrained adaptive testing, where large numbers of specifications have to be taken into account in the item…

In the May 2010 issue of "Psychological Bulletin," R. E. McGrath, M. Mitchell, B. H. Kim, and L. Hough published an article entitled "Evidence for Response Bias as a Source of Error Variance in Applied Assessment" (pp. 450-470). They argued that response bias indicators used in a variety of settings typically have insufficient data to support such…

On the third floor of the United States Holocaust Memorial Museum (USHMM), in Washington, D.C., inside a glass case, lie thousands of shoes. Old and mismatched, moldering after sixty years, they are what remains of countless Jews who were told to disrobe and who were subsequently murdered at Majdanek, Poland, during the final years of the…

Introduction: The study investigated the source preference criteria of library and information science students for their academic and personal information needs. Method: The empirical study was based on two methods of data collection. Eighteen participants wrote a personal diary for four months in which they recorded search episodes and answered…

This paper identifies and analyzes factors that influence international student selection of universities and the role that education marketing plays in the process. The research for the paper was inspired by work done by Canterbury on education marketing, published in the "Journal of Marketing for Higher Education". The study…

This empirical study explored the impression management techniques and standardized performances college students use on their Facebook profiles to ensure their peers believe they are fully participating in the undergraduate experience. Employing an ethnographic research design and data collected using participant-observation and interview…
