A 158 ITEM SURVEY, THE BEHAVIOR CLASSIFICATION CHECKLIST (BCC), WAS CONSTRUCTED TO MEASURE THE VARIABILITY IN INTENSITY REACTION TO PUPIL CLASSROOM BEHAVIORS. THE NINE SCALES OBTAINED BY FACTOR ANALYSIS WERE EXPLORED TO CHECK THEIR CONSTRUCT VALIDITY AGAINST OTHER MEASURES AND OTHER INFORMATION ON THE SUBJECTS. WHEN SPECIAL SCHOOL PERSONNEL AND…

ULTIMATE OBJECTIVE OF THIS STUDY IS A SYSTEM IN WHICH INSTRUCTORS MAY IDENTIFY RELEVANT AUDIENCE CHARACTERISTICS AND THEN DESIGN A PROGRAM TO OPTIMIZE LEARNING. MULTIPLE REGRESSION, FACTOR ANALYSIS, AND CROSS-VALIDATING PROCEDURES WERE USED TO ASSESS THE IMMEDIATE AND DELAYED LEARNING EFFECTS OF PROGRAMMED INSTRUCTION. INDEPENDENT VARIABLES…

AN INVESTIGATION WAS CONDUCTED TO DETERMINE A DEFINITION OF CURIOSITY THAT WOULD HELP IDENTIFY PERSONALITY PATTERNS OF CHILDREN WHO ARE MOST LIKELY TO BE EITHER HIGH OR LOW IN CURIOSITY. DATA COLLECTED IN EARLIER STUDIES WERE FACTOR ANALYZED TO IDENTIFY THE PERSONAL AND SOCIAL VARIABLES THAT DIFFERENTIATE CHILDREN HIGH IN CURIOSITY FROM THOSE LOW…

Using the work of Chester I. Barnard as a theoretical basis, the author developed a model to illustrate 36 combinations of leader styles. Six levels of efficiency (orientation to human needs) are plotted against six levels of effectiveness (task orientation) to form an Administrator Grid. The location of leaders within this grid is determined by…

An attempt is made to judge characteristics affecting a school district's fiscal performance by conducting a factor analysis on 74 variables having factor loadings of .30 or greater. The 16 factors studied (containing the 74 variables) include many facets of school board fiscal policy and information on the kinds of people who make the policies.…

The relationship of sample size to number of variables in the use of factor analysis has been treated by many investigators. In attempting to explore what the minimum sample size should be, none of these investigators pointed out the constraints imposed on the dimensionality of the variables by using a sample size smaller than the number of…

This report is on one aspect of a study that is trying to provide a reference basis for different researchers in their combined efforts to conceptualize and develop a theory and structure of human abilities and temperament. Specifically, the study is directed toward the identification of tests and other instruments that can serve as markers for…

A limitation of most past studies of university environments is that they have been restricted to institutions in the United States. Accordingly, in this study two approaches to the measurement of environments were applied to Japanese universities: factor analysis and classification of faculties according to the Environmental Assessment Technique…

A homophone is a word having the same pronunciation as another English word, but a different spelling. A list of 7,300 English homophones was compiled and used to construct two tests. Scores were obtained in these and on reference tests for J. P. Guilford's factors CMU, CSU, DMU, and DSU for 70 native speakers of midwestern American English from a…

Explicit formulas are derived for the asymptotic sampling variances and covariances of the maximum likelihood estimators for factor-analysis parameters in the special case where there is just one common factor. The effect of the number of variables on these variances and covariances is indicated. A formula is given showing to what extent the usual…

The report summarizes the aims of a 3-year program of work concerned with psychological factors in solar observing. Part I identifies several psychological factors which may affect solar observing and outlines a program of research. Part II is a report of a program of studies dealing with the application of visual perceptions in solar flare…
