Teaching is a stressful profession with a high turnover rate. Schools and related institutions need to take more action to support teachers and keep teacher stress at a manageable level. The continued research and practical effort require measures to examine teachers' stress in a briefer and accurate manner. The Teacher Stress Scale is a recently…

In this investigation, we used real data to assess potential differential effects associated with taking a test in a test center (TC) versus testing at home using remote proctoring (RP). We used a pseudo-equivalent groups (PEG) approach to examine group equivalence at the item level and the total score level. If our assumption holds that the PEG…

This article provides a single, common-case study of a test retrofit project at one Colombian university. It reports on how the test retrofit project was carried out and describes the different areas of language assessment literacy the project afforded local teacher stakeholders. This project was successful in that it modified the test constructs…

Background: Digital-first assessments leverage the affordances of technology in all elements of the assessment process--from design and development to score reporting and evaluation to create test taker-centric assessments. Objectives: The goal of this paper is to describe the engineering, machine learning, and psychometric processes and…

The representativeness, recency, and size of norm samples strongly influence the accuracy of inferences drawn from their scores. Inadequate norm samples may lead to inflated or deflated scores for individuals and poorer prediction of developmental and academic outcomes. The purpose of this study was to apply Kranzler and Floyd's method for…

Current science education reform efforts emphasize teaching K-12 science using hands-on, inquiry activities. For maximum learning and probability of implementation among inservice teachers, these strategies must be modeled in college science courses for preservice teachers. About a decade ago, Morehead State University revised their science…

This study examined students' competencies in engineering education at the university level. First, we developed a competency model in one specific field of engineering: process dynamics and control. Then, the theoretical model was used as a frame to construct test items to measure students' competencies comprehensively. In the empirical…

Longitudinal change in the average Z scores for four groups of pupils sorted by quartiles was examined for its stability over three years. The data, collected from 1998 to 2009, was obtained from nine cohorts of Japanese junior high school pupils totaling 1,962 subjects. It showed illusionary declines among the mid-range pupils but improvements…

This article describes the results of a simulation study to investigate the impact of missing data on the detection of differential item functioning (DIF). Specifically, it investigates how four methods for dealing with missing data (listwise deletion, zero imputation, two-way imputation, response function imputation) interact with two methods of…

Although the Angoff procedure is among the most widely used standard setting procedures for tests comprising multiple-choice items, research has shown that subject matter experts have considerable difficulty accurately making the required judgments in the absence of examinee performance data. Some authors have viewed the need to provide…

Examined the P scale of the Eysenck Personality Questionnaire in three samples of normal Canadian and Japanese students who obtained either very high or very low means on the P scale. Psychometric problems were identified in the sample with a low P mean. Recommended that the scale be renamed. (JAC)

Investigated examiner errors on 46 protocols completed by certified and/or licensed clinical and school psychologists. Findings showed that nearly 83 percent of the protocols contained at least one error, about one-half containing errors that resulted in an incorrect Mental Processing Composite Global score and/or Achievement Global score.…

Total errors served as the criterion, and combined errors from the first four subtests served as the predictor. Correlation coefficients of .89 and .88 were obtained in validation and cross-validation phases. The first four subtests provide a suitable, stable estimate of the total score in this population.

A model is proposed that describes subject behavior on repeat paired comparison preference tests. The model extends prior work in this area in that it explicitly allows for abstentions and permits the derivation of individual true scores of discrimination ability as well as conditional estimates of proportionate preference.

Examines practices that encourage false negatives and false positives on licensing and certification tests designed to protect the public. Recommends increasing the amount of testing or raising the required passing score for repeat test takers. (FMW)
