To address the computational constraints of parameter estimation in the polytomous Cognitive Diagnosis Model (pCDM) in large-scale high data volume situations, this study proposes two two-stage polytomous attribute estimation methods: P_max and P_linear. The effects of the two-stage methods were studied via a Monte Carlo simulation study, and the…

Intended for employers concerned about problem solving and communication within their organization, this document outlines a strategy for developing an instrument that would provide objective data rather than impressionistic data. A questionnaire was designed to explore the relationship between the central constructs of problem solving and…

This paper considers, from a theoretical point of view, two measurement approaches used in measuring success and failure in skills tests in physical education. The first, "fixed length" (FL) testing, entails counting the number of successful performances in a fixed number of trials. The second, "trials-to-criterion" (TTC)…

Scores on standardized tests may be expressed in a variety of different modes. Raw scores, grade equivalents, percentile ranks, stanines, and standard scores are the major types in use today. The study investigated whether the mode or scale used to express scores affected the magnitude of group statistics, specifically, t and r (the t-test of the…

The extent to which national performance on an achievement test battery changed over a 4-year period was studied, and the comparative performance of students in school districts taking the test series for the first time was compared with that of students in districts that had used the battery at least once in one or more grades. The seventh…
