This research examines the reasons behind marketing majors' decision to select marketing as a major, where students have the option to select more than one major toward their undergraduate degree. Results of surveys conducted at two universities, one in Australia and one in New Zealand, provide some new findings as well as extending findings from…

Unfolding response models, a class of item response theory (IRT) models that assume a unimodal item response function (IRF), are often used for the measurement of attitudes. Verhelst and Verstralen (1993)and Andrich and Luo (1993) independently developed unfolding response models by relating the observed responses to a more common monotone IRT…

Evaluation is increasingly taken as a public good, as an activity aimed at development and betterment. At the same time, evaluation is increasingly integrated in accountability movements and in institutionalized systems for governance. It is also embedded in a consumer-oriented New Public Management ideology. Against this background, it is high…

In November of 2007, Alberta Advanced Education and Technology contracted Insightrix Research, Inc. to conduct a survey of individuals who graduated from post-secondary institutions in Alberta in the fall of 2005 or the spring of 2006 (excluding apprenticeship graduates, who are surveyed through a separate initiative). The purpose of the survey is…

Our research question was whether we could develop a feasible technique, using Bayesian networks, to diagnose gaps in student knowledge. Thirty-four college-age participants completed tasks designed to measure conceptual knowledge, procedural knowledge, and problem-solving skills related to circuit analysis. A Bayesian network was used to model…

Background: The impact of speech therapists' conceptual frameworks on their clinical methods tends to be ignored or taken for granted by today's practitioners. One way to show the importance of such frameworks is to study how they were used previously. John Thelwall, a 19th-century elocutionist, offers a rich source for studying the influence of…

In this study some alternative item selection criteria for adaptive testing are proposed. These criteria take into account the uncertainty of the ability estimates. A general weighted information criterion is suggested of which the usual maximum information criterion and the suggested alternative criteria are special cases. A simulation study was…

A total of 149 students enrolled in an undergraduate nursing research methods course participated in a study comparing three strategies for using formative evaluation (test feedback throughout a course) to predict students at risk of failure at summative evaluation (the final examination). Students took 12 weekly multiple-choice quizzes, which…

In this paper four classes of procedures for measuring the instructional sensitivity of reading comprehension test items are reviewed. True experimental designs are not recommended because some of the most important reading comprehension variables do not lend themselves to experimental manipulation. "Ex post facto" factorial designs are…

Differences between traditional linear regression and a Bayesian approach to classification are discussed. Classification consists of assigning subjects to one of several available treatments on the basis of their test scores when the success of each treatment is measured by a different criterion. Formulating this problem as an empirical Bayes…

The three-parameter logistic model discussed was used by CTB/McGraw-Hill in the development of the Comprehensive Tests of Basic Skills, Form U (CTBS/U) and the Test of Cognitive Skills (TCS), published in the fall of 1981. The development, standardization, and scoring of the tests are described, particularly as these procedures were influenced by…

A simulation study to determine appropriate linking methods for adaptive testing items was designed. Three basic data sets for responses were created. These were randomly sampled, systematically sampled, and selected data sets. The evaluative criteria used were fidelity of parameter estimation, asymptotic ability estimates, root-mean-square error…

Despite advances in common factor analysis, a review of 89 studies published in four selected journals between 1963 and 1976 indicated that behavioral scientists preferred principal components analysis, followed by varimax or orthogonal rotation. Resultant row sums of squares of factor matrices from principal component analyses of real data sets…

This document contains summaries of six courses presented at the Second Annual Presessions of the American Educational Research Association: (1) Bayesian statistical analysis, (2) curriculum research and evaluation, (3) design and analysis of comparative experiments in education, (4) educational research management procedures, (5) multivariate…

This paper considers the application of Bayesian techniques for simultaneous estimation to the specification of regression weights for selection tests used in various technical training courses in the Marine Corps. It concludes that a hypothesis of complete generalization of the predictor-criterion relationship would only be retained for selected…
