Gas Turbine Engines (GTE) have the highest power-to-weight ratio among Internal Combustion Engines (ICE). Its modularity and ability to utilize various types of fuel make it highly recommended in power plants, naval transportation, and, of course, the most equipped in aviation. The lack of GTEs' real data is increasing a recognized need for…

The impetus for this paper stems from a concern about directions and progress in the measurement of the Technological Pedagogical Content Knowledge (TPACK) framework for effective technology integration. In this paper, we develop the rationale for using a seven-criterion lens, based upon contemporary validity theory, for critiquing empirical…

Standardizing aspects of assessments has long been recognized as a tactic to help make evaluations of examinees fair. It reduces variation in irrelevant aspects of testing procedures that could advantage some examinees and disadvantage others. However, recent attention to making assessment accessible to a more diverse population of students…

Psychometric practice does not always converge with the advances of psychometric theory. In order to investigate this gap, the authors focus on the 10 most used psychological tests in Europe, as identified by recent surveys. The article analyzes test manuals published in 6 different European countries for these 10 most used tests. A total of 32…

This handbook is designed as a quick reference for first-year teachers who find themselves in an assessment driven environment with little experience to help make sense of the language, underlying philosophy, or organizational structure of the assessment system. The handbook begins with advice on developing and evaluating effective learning…

In response to Ebel's article (TM 508 146) the author points out that, in emphasizing what a test is intended to measure, the vital question of what should be measured is set aside. While explicit specifications for a test should be encouraged, questions of worth ought to be prominent in designing and selecting tests. (Author/LC)

The increasing relation between domain-referenced measurement and its implications in instruction are discussed with the argument that construction methods available do not guarantee content validity which needs more attention to be effective. Two domain-referenced testing procedures illustrate construction and validity problems. (CM)

In an attempt to restore the symmetry and balance between the study of person and item variation, this paper presents a novel methodology construct specification equations, which allows one to ascertain from the lawful behavior of items what an instrument is measuring. (Author/PN)

Tests producing results that are used to make important decisions about students, schools, and curricula should not be developed locally by teachers. Although district educators at all levels need to become familiar with measurement nuances, the development of high stakes tests is best left to measurement professionals. Includes four references.…

A procedure is suggested for test development and construct validation based on a theory about the criterion performance. The method is illustrated by describing a study concerned with the selection of medical school students, where the criterion is a measure of clinical problem-solving ability. (Author/LMO)

Argues that teachers need to become "informed consumers" of standardized tests in order to influence decisions about test use and about ways to help students perform at their best. Six strategies for considering the content of a test form are presented. (LR)

Three kinds of instructionally sensitive achievement tests are described which provide useful information on formal schooling proficiencies: placement, progress, and attainment tests. Procedures to design, develop, and empirically verify attainment and placement tests are presented. The methodology is designed to ensure that the test instruments…
