Because the Brookover Self-Concept of Ability Scale has been widely used during the past decade as an index of general academic self-concept, this scale was selected to investigate the hypotheses in the present study. The purpose of this study were twofold: (1) to investigate the dimensionality of academic self-concept through patterns of item…

A 4-year United States Office of Education prekindergarten-kindergarten series of research studies has provided data useful in predicting school success. The present study compares test scores of the Complete Assessment Battery administered before the children entered kindergarten with scores of the same children on the Metropolitan Readiness…

This monograph contains the third section, operations at the factor level, of a report of studies done in Helsinki, Finland, describing school achievement in terms of ability, trait, situational, and background variables. The report (1) investigates the structure of school achievement, (2) describes school achievement in terms of selected…

An audiovisual sensory test on 66 educational psychology students supported the contention expressed in Holmes'"Substrata Factor of Reading" that the individual differences in the sensory modes are not necessarily highly correlated. It further suggested that there exists an "intersensory facilitation," but that facilitation is probably not at the…

Livingston's reliability coefficients and Harris' indices of efficiency were computed along with the classical internal consistency coefficients, KR-20's (Kuder-Richardson internal consistency coefficient), for 678 criterion-referenced tests in the A through E levels of an individualized mathematics program. The coefficients were carefully studied…

This project investigates changes in the socioeconomic level (SEL) of the families of Puerto Rican school children in the last 10 years. The effects of these changes on selected educational variables--reading comprehension, school dropouts, and admission to institutions of higher education--are studied. A comparison is made between data collected…

An approach for clearer observation of differences when evaluating educational programs is presented. The standardized tests utilized in evaluating programs are designed to measure topics commonly taught and to maximize individual differences. This masks between-program differences and the unique aspects of different programs. Analysis of item…

Four-hundred and nine students (grades 8, 10, 12 and 14) were given logical syllogism problems of the form "If p...then q" along with tests of dogmatism and intolerance of ambiguity. Aptitude scores were also obtained. Major results indicated that expressed dogmatism and intolerance of ambiguity were negatively correlated with syllogistic…

This memorandum reports results of an analysis designed to obtain answers to the following questions: (1) How does the Overall High School Average compare with Converted Rank in Class as a predictor of Freshman Year Grades in college? and (2) Will more detailed information provided by analysis of high school records by subject help to improve…

The primary purpose of this study was to obtain estimates of the human attribute requirements of the job elements of the Position Analysis Questionnaire (PAQ). A secondary purpose was to explore the reliability of job-related ratings as a function of the number of raters. A taxonomy of 76 human attributes was used and ratings of the relevance of…

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…

Besides the ubiquitous Pearson product-moment r, there are a number of other measures of relationship that are attenuated by errors of measurement and for which the relationship between true measures can be estimated. Among these are the correlation ratio (eta squared), Kelley's unbiased correlation ratio (epsilon squared), Hays' omega squared,…

Recent studies have shown that in heterogeneous populations differential validities are often found in the population subgroups. In the light of the increasing societal emphasis on higher education, the valid prediction of academic success for all racial groups has become a necessity. This study is concerned with the differential validity for…

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…
