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…

Student surveys have gained prominence in recent years as a way to give students a voice in their learning process, and teacher self-reports have always been an effective instrument for revealing the planning, intentions, and expectations behind a given lesson. Though student and teacher surveys are widely used, extant research in education has…

Two quantitative measures of school performance are currently used, the average points score (APS) at Key Stage 2 and value-added (VA), which measures the rate of academic improvement between Key Stage 1 and 2. These figures are used by parents and the Office for Standards in Education to make judgements and comparisons. However, simple…

Background/Context: The target of assessment validation is not an assessment but the use of an assessment for a purpose. Although the validation literature often provides examples of assessment purposes, comprehensive reviews of these purposes are rare. Additionally, assessment purposes posed for validation are generally described as discrete and…

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…

The National Staff Development Council (NSDC), a private, nonprofit association, has outlined high standards for educator professional learning. One demonstration of NSDC's commitment to the goal of ensuring all schools support and use high standards for professional learning is the organization's investment in developing an instrument to assess…

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…

Explores the structure of the Minnesota Multiphasic Personality Inventory (2nd ed.) Low Self-Esteem Content Scale using principal components analysis. Associations with other measures provide evidence of convergent and discriminant validity. (Contains 16 references.) (Author/GCP)

In general, it is assumed that distinct true values will be found behind what is actually measured in surveys. By acquiring sufficient knowledge of measurement error, its extent and nature, we are supposed to be able to obtain adequate knowledge of underlying properties. It could be maintained, however, that this idea of a stable and…

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)

This report of a study conducted by the National Council for the Social Studies (NCSS) reviews, interprets, and disseminates findings of the National Assessment of Educational Progress (NAEP) assessments in citizenship and social studies. The study represents an investigation funded by the Education Commission of the States and coordinated by a…

Since the use of bibliometric instruments has grown and will continue to grow in the future, the quality, availability, and accessibility of data on publications and citations is of tantamount importance. But equally important is a correct use of the data. This means that an important task of the bibliometric field is to highlight not only what…

The main purpose of this paper is to draw attention to some facts and ideas that perhaps can help to identify problems or fields for development and research within the evaluation of training. Topics for group discussion are preceded by material on some basic concepts of evaluation and educational measurement. The ratio scale, the interval scale,…

The effects of aggregation on the reliability of measures of academic performance were explored in two studies. In the first study, 30 elementary-age children were tested four times on the same forms of the Woodcock Reading Mastery Tests and the Ginn 720 Reading Passage measures. Group stability coefficients, within-subject reliability…
