A theory was conceived to explain student, teacher, and classroom environment characteristics or constructs, which may influence student attitudes toward school and various subjects. A questionnaire representing the constructs, the Inventory of Affective Aspects of Schooling (IAAS), was developed and administered to 601 students in grade 4. Factor…

Charles Spearman originally suggested in 1927 that the varying magnitudes of the mean differences between whites and blacks in standardized scores on a variety of mental tests are directly related to the size of the tests' loadings on g, the general factor common to all complex tests of mental ability. Several independent large-scale studies…

The Pittsburgh Adjustment Survey Scales were developed to meet the need for the objective evaluation of the social behavior of elementary school-age boys using the observations of classroom teachers. An initial item pool was reduced to 94 items by an extreme-group procedure (202 subjects). A factor analysis (209 subjects) of the inventory resulted…

Piaget has hypothesized that concrete and formal operations can be described by specific logical models. The present study focused on assessing various aspects of four concrete operational groupings and two variations of two formal operational characteristics. Six hundred twenty-two 9-14 year old students participating in the Human Sciences…

The results of this study empirically demonstrate the importance of cross-validating an instrument intended for use in a future study. The instrument used was the Teachers' Practices Questionnaire (TPQ) which had been devised in 1963 to measure teachers' subjective role expectations. Three samples of undergraduate and graduate students who were,…

The generalizability of factor structures of student ratings of instruction based on instructors' individual differences was examined. The subjects were instructors from the humanities, social science, and mathematics divisions who had had their courses evaluated at least twice using the same evaluation questionnaire. The data from the three…

The equivalency of item sampling and student sampling of attitudes of college students was investigated. A factor analysis of student-sampled data collected during Spring 1968, was compared with a factor analysis of item-sampled data collected each quarter from Fall 1968, through Winter 1970, at Mankato State College, using the Campus Environment…

This paper examines interaction in a school class through the factor-analytical P-technique, considers the behavior of the factor scores in combination with certain other variables included in the interaction matrix, explores the formation of homogeneous groups of lessons in a grouping analysis based on the factor scores, and compares this latter…

The validity of a Hebrew version of the Illinois Course Evaluation Questionnaire was investigated in eighty courses in science and engineering at the Israel Institute of Technology. Factor analysis revealed a reasonable correspondence between empirical structure and that afforded by logic and intuition. (Author/JKS)

Explores the factor structure of the Mooney Problem Check List (MPCL) at the junior and senior high school level by undertaking a large obverse factor analysis of item responses in three adolescent criterion groups. (Author/DEP)

Common factor scores were compared to unfactored data-level variables as predictors in terms of the correlation of a criterion with the predicted value in multiple regression equations applied to replication (cross-validation) samples. (Editor)

Intercorrelations among primary personality traits of the Clinical Analysis Questionnaire were factor analyzed with 925 normal adults and 950 clinical cases. When separate analyses were carried out for men and women, 10 second-order factors were clearly replicated across the two data sets. (Author)

Factor analysis of an instructor rating form administered to three successive student and teacher populations revealed a reasonably consistent factor structure across analyses. Substantial changes in proportions of common variance appeared when comparing anonymous and nonanonymous conditions. (Author/LBH)

Since The Graduate Record Examination-Verbal measures two factors (reading comprehension and discrete verbal ability), the unidimensionality of item response theory is violated. The impact of this violation was examined by comparing three ability estimates: reading, discrete, and all verbal. Both dimensions were highly correlated; the impact was…

Two hundred child care program directors were surveyed as to their most pressing administrative concerns. The primary problem areas targeted by most administrators involved (1) evaluating personal effectiveness; (2) developing a center's philosophy; (3) evaluating the effectiveness of the center for the child; and (4) establishing effective…
