The purpose of this paper is to derive explicit estimates of the parameters of a latent structure model when the skills represented by the test items are hierarchically related. Two special cases are described, which may be used as an approximation to the Dayton and Macready model and also provide initial estimates in an iterative estimation…

Because it is difficult to ascertain the dimensionality of a test composed of binary items through the use of factor analysis alone, a method is proposed that combines item characteristic curve (ICC) theory with factor analysis. Factor structure of tetrachoric correlations is distorted by non-normal distribution of ability. Item characteristics…

A STUDY WAS MADE TO DEVELOP A QUICK AND ACCURATE METHOD FOR MEASURING OCCUPATIONAL ASPIRATIONS, ADDING TO KNOWN EXPLANATORY AND PREDICTIVE TECHNIQUES CONCERNING THE OCCUPATIONAL SELECTION PROCESS. "LEVEL OF OCCUPATIONAL ASPIRATION" (LOA) WAS THE CONCEPTUAL FOCAL POINT OF THIS PROJECT. SUBJECTS OF THE PROJECT, APPROXIMATELY 450…

THE CROSS-CULTURAL VALIDITY OF AN EVOLVING CONCEPTUAL MODEL FOR PARENT BEHAVIOR WAS INVESTIGATED. PREVIOUS RESEARCH STUDIES SUGGEST THAT THE PARENT BEHAVIOR DIMENSIONS OF SEVERAL CONCEPTUAL MODELS COULD BE INTEGRATED BY VISUALIZING THESE DIMENSIONS AS PLOTTED ON THE SURFACE OF A SPHERE. THE PROPOSED SPHERICAL CONCEPTUAL MODEL WAS OBTAINED USING…

THIS DOCUMENT IS A POPULATION STUDY OF JUNIOR (JKP) AND SENIOR (SKP) KINDERGARTEN PUPILS IN TORONTO, CANADA. IT IS TO BE USED IN CONJUNCTION WITH A LONGITUDINAL "STUDY OF ACHIEVEMENT" (PS 000 355) THAT WILL ATTEMPT TO ASCERTAIN WHETHER THE EFFECTS OF JUNIOR KINDERGARTEN ON PUPILS' SCHOOL ACHIEVEMENT TEND TO DIMINISH FROM GRADE TO GRADE…

THE EXTENT TO WHICH READING READINESS TESTS RELATE TO A GROUP OF INTELLIGENCE TESTS WAS INVESTIGATED. APPROXIMATELY 300 FIRST GRADERS IN 15 CLASSROOMS IN GEORGIA WERE ADMINISTERED THE METROPOLITAN READINESS TEST, THE LEE CLARK READINESS TEST, AND THE CALIFORNIA TEST OF MENTAL MATURITY. FACTOR ANALYSIS WAS USED TO ANALYZE THE DATA. THE SUBTESTS OF…

APPROXIMATELY 180 EIGHTH- AND 180 NINTH-GRADE STUDENTS, PLACED IN THREE ABILITY "TRACKS," WERE ADMINISTERED AN 80-ITEM ATTITUDE SURVEY AND AN 80-ITEM MOTIVATION INVENTORY. THE RESULTS OBTAINED WERE DEVELOPED AS PART OF A LONG-RANGE STUDY TO IMPROVE SCHOOL ATTITUDES AND MOTIVATION THROUGH INCORPORATING A REVISION OF INSTRUCTIONAL AND…

TO INVESTIGATE HOW ATTITUDES TOWARD EDUCATION INFLUENCE PERCEPTION OF DESIRABLE TEACHER BEHAVIORS, AN EDUCATIONAL ATTITUDES INSTRUMENT (KERLINGER'S ES-VII) AND AN 80-ITEM TEACHER BEHAVIORS Q-SORT WERE ADMINISTERED TO 80 ELEMENTARY AND SECONDARY SCHOOL TEACHERS. THIRTY-TWO TEACHERS WERE RATED AS "PROGRESSIVE," 32…

NEW INTELLECTUAL APTITUDES WERE INVESTIGATED TO DETERMINE TO WHAT EXTENT THEY INFLUENCE ACHIEVEMENT IN NINTH-GRADE ALGEBRA AND GENERAL MATHEMATICS COURSES. TESTS AND CRITERIA WERE COMPLETED FOR APPROXIMATELY 400 STUDENTS IN THE NINTH GRADE. THEY WERE ENROLLED IN ONE OF FOUR MATHEMATICS COURSES AND ADMINISTERED ACHIEVEMENT EXAMINATIONS UPON…

THE PURPOSE OF THIS STUDY WAS TO EVALUATE THE PROGRAM ANALYZER, KINESCOPE, AND AUDIOTAPE AS AIDS IN TRAINING TELEVISION TEACHERS. FOLLOWING 10-MINUTE PRESENTATIONS, EACH TEACHER'S PERFORMANCE WAS REVIEWED BY ONE OF FIVE METHODS--(1) SOUND ONLY, (2) SOUND AND PROGRAM ANALYZER, (3) KINESCOPE ONLY, (4) KINESCOPE AND PROGRAM ANALYZER, OR (5)…

Mastery of sixteen "life skills" tasks will be a Seattle Public Schools graduation requirement beginning in 1981. Five forms of the Minimum Competencies Performance Test, which will be used to measure mastery of those tasks, are presently being developed and field tested. This report presents the results of the analysis of the first…

Several advantages to the use of factor scores as independent variables in a multiple regression equation were found. To help select the most desirable type of factor score on which to calculate a regression equation, computer-based Monte Carlo methods were used to compare the predictive accuracy upon replication of regression of five…

This report presents intercorrelations and factor analyses of items from the principal questionnaire administered as part of the Educational Opportunities Survey (EOS). The correlations among selected items from the questionnaire were computed (1) to display their interrelationships, (2) to document them for other researchers, and (3) to serve as…

This study was designed to factor analyze the correlation matrices of a number of studies utilizing the Illinois Test of Psycholinguistic Abilities (ITPA). All of the correlation matrices were analyzed on the same program using the same criteria. By this approach, it was possible to examine trends between studies. More factors tended to appear as…

This study examines the relationship between physical attractiveness and behavior by assessing whether behavioral differences exist between children judged by adults to be physically attractive and unattractive. Sixty-four 3- and 5-year-old boys and girls were selected as subjects on the basis of physical attractiveness. Three types of same-age…
