This study compared three approaches to the two-factor experiment with repeated measures on one factor: (1) the conventional mixed model analysis of variance, (2) the Greenhouse-Geisser conservative analysis of variance, and (3) multivariate extensions of analysis of variance. Computer simulated data were used in a total of 96 sets of covariance…

The purpose of this study was to analyze data collected from participants in the Pennsylvania Governor's School for the Arts (PGSA) in terms of their relevance to science education. Its objective was to investigate relationships between variables common to the arts and sciences as a means for hypothesizing alternative approaches for growth in…

Longitudinal support was obtained for a positive relationship between cognitive and social development. From a large sample of kindergarteners, three groups of 12 children of comparable age and IQ were selected as displaying substantial, moderate, or no mastery of Piagetian concrete operations. From kindergarten through second grade, the social…

This report covers part of a project designed to develop and to make available to research workers markers for some of the temperament factors that have been established in the factor-analytic literature. An earlier report describes 28 such factors and defines several divisions of each factor, called subfactors, that appear in the literature to be…

This study involved an investigation of the use of Pearson r, tetrachoric r, phi, phi/phi maximum, and Kendall Tau-B coefficients as measures of association for the incomplete principal components analysis of simulated Likert scale attitudinal data, based on a known factor pattern and possessing different types of severe departures from normality.…

Response latency data from two studies of 30 5-to 7-year-old and 50 3 to- 4-year-old children were analyzed to assess the interrelations of response latencies with previously reported orienting response data and standard learning data. Ss in the first study were tested on an oddity task in three distraction conditions (mirror, sound, and control),…

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…
