Educational reform priorities such as emphasis on quantitative modelling (QM) have positioned undergraduate biology instructors as designers of QM experiences to engage students in authentic science practices that support the development of data-driven and evidence-based reasoning. Yet, little is known about how biology instructors adapt to the…

The measurement of higher-order competencies within a tertiary education system across countries presents methodological challenges due to differences in educational systems, socio-economic factors, and perceptions as to which constructs should be assessed (Blömeke, Zlatkin-Troitschanskaia, Kuhn, & Fege, 2013). According to Hart Research…

Many countries use national-level surveys to capture student opinions about their university experiences. It is necessary to interpret survey results in an appropriate context to inform decision-making at many levels. To provide context to national survey outcomes, we describe patterns in the ratings of science and engineering subjects from the…

The study scrutinized the probable interaction between using cognitive test-taking strategies, reading proficiency, and reading comprehension test performance of Iranian postgraduate students, who studied English as a foreign language. The study also probed the extent to which the participants' test performance was related to the use of certain…

Replied to Hays and Stacy's critique of an article by Holmes, Dungan and McLaughlin in which the validity of the Minnesota Multiphasic Personality Inventory alcoholism scales was questioned. Presents support for the original conclusions and comments on Hays and Stacy's reanalysis. (JAC)

Validity coefficients, standard errors of estimate, and prediction are discussed. An argument is made for the potential utility of tests with validity coefficients of .60, .50, .40, and even .30, because they can predict the extremes, which is especially valuable for many purposes, such as counseling, college admissions, and personnel selection.…

Ways are suggested in which validation studies may be carried out by personnel workers who use tests in selection and placement. The correlational techniques discussed are the product-moment correlation coefficient, biserial correlation coefficient, tetrachoric coefficient of correlation. The summarizing techniques (a term used to refer to methods…

In this paper it is argued that the problem of construct validation in the construction of instruments and indicators is an important problem for educational researchers and practitioners; moreover, it is claimed that the popular notion of operational definition is a misleading idea which has obscured the problem of construct validity in…

Measurement terms used in Title I evaluation are contained in this glossary. Several types of measurement techniques are identified and defined. Other measurement terms which are defined include those relating to validity, reliability, statistical analysis, test interpretation, and program effectiveness. (DWH)

Compared were the relationships between the Wechsler Intelligence Scale for Children and the Illinois Test of Psycholinguistic Abilities by means of the statistical methods of factor analysis and canonical correlation analysis as applied to scores of 63 children (mean age 7 1/2 years) referred for reading problems.

This tutorial summarizes some of the widely known limitations of tests of statistical significance and then focuses on extracting measures of variation accounted for as a supplement to significance testing. Two measures of variation accounted for, eta squared and omega squared, are discussed. Computational formulas, computational examples, and…

The test scores of some examinees on a multiple-choice test may not provide adequate measures of their abilities. The goal of appropriateness measurement is to identify such individuals. Earlier theoretical and experimental work considered examinees answering all, or almost all, test items. This article reports research that extends…

This study tests the appropriateness of Torrance's assumptions of trait independence and the combinability of measures (Torrance Tests of Creative Thinking) with respect to the scoring of the tests for a younger population and estimates the homogeneity of the scores. The sample consisted of 128 elementary school children. Results indicate that…

Provides necessary statistical information for comparing subtests of the Test of Language Development-Primary (TOLD-P) to an individual's mean scaled score at each of five age levels. While it would be convenient to use the average of these values across the age levels, this procedure is inappropriate for the TOLD-P. (Author/JAC)
