Previous systematic reviews indicate a lack of reporting of reliability and validity evidence in subsets of the medical education literature. Psychology and general education reviews of factor analysis also indicate gaps between current and best practices; yet, a comprehensive review of exploratory factor analysis in instrument development across…

In this research investigation of score comparability for language minority students (English language learners [ELLs] and former English language learners), we examined 3 indicators of score comparability (reliability, internal test structure, and differential item functioning) for 4th and 8th grade students who took the NCLB-mandated content…

This report evaluates the construct coverage of the e-rater[R[ scoring engine. The matter of construct coverage depends on whether one defines writing skill, in terms of process or product. Originally, the e-rater engine consisted of a large set of components with a proven ability to predict human holistic scores. By organizing these capabilities…

The Science Teacher Inventory of Need (STIN) was developed specifically to assess the perceived needs of science teachers in developing nations. The purpose of this reported study was to apply factor analysis to the perceived needs data collected from a sample of Malaysian secondary science teachers in order to clarify further the factorial…

This report presents a thematic summary of the AERA papers dealing with test development, interpretation, and use, presented at the 1971 meeting in New York City. Papers were grouped into the following categories: test development and validation; inventory development and validation; measurement of creativity; factors in test performance; use of…

Factor analysis was used to test the hypothesis that College Level Examination Program (CLEP) General Examinations, when administered to students who have completed 2 years of college, do not measure anything different from that measured by the traditional battery of pre-college aptitude examinations. The CLEP examinations were taken in the fall…

A random sample of 225 grade one children were given the Canadian Cognitive Abilities Test (CCAT) on two occasions within seven months. During the second administration the WISC was also administered. KR-20 reliabilities of the CCAT for the two administrations were respectively .83 and .74. The test-retest reliability was .75. The correlation…

This document is an English-language abstract (approximately 1,500 words) of part of a comprehensive research project concerning the Finnish matriculation examination. The goal of the project was to explore the matriculation examination as a series of tests indicative of ability differences between individuals, regardless of their causes. The…

THE AUTHOR POINTS OUT PROBLEMS IN TEST RESEARCH AND INTERPRETATION, SOME OF WHICH ARE DUE TO CONFLICTS BETWEEN THE FINDINGS OF THE DATA ANALYST WHO IS RESTRICTED TO BASING HIS DECISIONS ON SELECTED DATA ONLY, AND THE TEST INTERPRETER WHO IS AWARE OF VARIABLE VALIDITIES OF SUCH UNTESTED FACTORS AS SITUATIONAL ANXIETY, PERSONALITY, MOTHER-TONGUE…

Bayesian estimation procedures are summarized and numerically illustrated by means of simulation methods. Procedures of data generation for simulation purposes are also delineated and computationally demonstrated. The logistic model basic to the Bayesian estimation procedures is shown to be explicit with respect to the probability distribution…
