This paper reviews studies of teacher anxiety (stress and tension) with a focus on the incidence, sources, and effects of anxiety, and methods of reducing it. Previously, global definitions of anxiety have been used, and assessment has been largely restricted to paper-and-pencil measures. The incidence of anxiety among teachers, both beginning and…

One approach to the study of structures that underly receiver response to perceptual stimuli has been that of factor analysis. This method was used to study responses of 92 students at the University of Connecticut to drug abuse commercials. Responses to five anti-drug television commercials were categorized according to: (1) "relative…

Item responses of two samples each of 622 normal and 573 educable mentally retarded children, 6 to 15 years of age, on Raven's Colored Progressive Matrices were submitted to a principal components analysis and varimax rotation. The following four factors were obtained: continuity and reconstruction of simple and complex structures, discrete…

This is one of a series of reports on the National Longitudinal Study of Mathematical Abilities (NLSMA). This report is a discussion of many of the programs from the SMSG Computer Program Library as it existed in June, 1972. Major programs included involve item analysis, attitude item analysis, scale scoring, correlation and t-test, stepwise…

Under some circumstances, it is desirable to compare the factor patterns obtained from different factor analyses. To date, the best method of simultaneously achieving simple structure and maximum similarity is the technique devised by Bloxom (1968). This technique simultaneously rotates different factor patterns to maximum similarity and varimax…

Three topics in factor analysis are covered: a) a reliability coefficient for assessing the quality of a maximum likelihood factor analysis, b) an application of three-mode factor analysis to serial learning data, showing variations in learning curves over stages of learning and individuals, and c) the use of personal probability functions to…

This paper is concerned with the study of similarities and differences in factor structures between different groups. A common situation is when a battery of tests has been administered to samples of examinees from several populations. A very general model is presented, in which any parameter in the factor analysis models (factor loadings, factor…

Guttman's "rank-reduction" theorem is employed to demonstrate how most of the algebra and computational work for standard correlational and analysis of variance methods can be examined within a single matrix system. Analyses of both correlational and experimental data are illustrated with an easy-to-use computer program. This application…

Measurement properties of the written rules tests were examined to determine their suitability for assessing driver knowledge and skill. It was concluded that the tests, as measurement tools for granting or renewing a driver's license, were not adequate. Recommendations for test improvement and a sample test copy are included. (AG)

In order to examine the effects of such demographic characteristics as sex, age, education, occupational tenure and status, company and job tenure and management level on job satisfaction, the responses of 1,139 exempt employees in six companies to 28 satisfaction scales were factor analyzed. In comparing the factor structures for the various…

Aitkin's generalized least squares (GLS) principle, with the inverse of the observed variance-covariance matrix as a weight matrix, is applied to estimate the factor analysis model in the exploratory (unrestricted) case. It is shown that the GLS estimates are scale free and asymptotically efficient. The estimates are computed by a rapidly…

Data required for evaluating a Criterion Referenced Measurement (CRM) is described with a matrix. The information within the matrix consists of the "pass-fail" decisions of two CRMs. By differentially defining these two CRMs, different concepts of reliability and validity can be examined. Indices suggested for analyzing the matrix are listed with…

Mathematics items developed to measure concept attainment for the topics of set theory, division, and expressing relationships were studied. A completely crossed design with 30 concepts and 12 tasks was used. The items were administered to 196 girls who had just completed the fifth grade and to 195 boys who had just begun the sixth grade.…

This study's aim was to explore the relationship of acquiescence, social desirability (SD), and defensiveness response styles with first, second, and any higher order factors on the 16 PF. All the various kinds of response bias indexes were appreciably correlated with the first order factor scales. Each kind of response style measure predominantly…

In a previous Semantic Differential study, Ayrer and Farber (1972) reported the results of a factor analysis which utilized a matrix sampling approach. Some problems were encountered (negative eigen-values). The current study did not involve matrix sampling, but the same basic results were obtained. This suggests matrix sampling may be an…
