This study was designed to investigate the impact that collective negotiations have had on teachers' salaries in Ohio; and the relationships between the incidence of work stoppages and the characteristics of Ohio school districts. Since the focus of this was twofold, it was found necessary to employ several statistical techniques to accomplish the…

Factors which may explain differences in the level of achievement among elementary schools with similar socioeconomic status and racial composition were explored. Based on data from a statewide assessment in 1969, 25 schools were identified as having similar socioeconomic status and racial composition but significantly different levels of…

This collection of papers, concerned with the nature and theory of intelligence, forms part of a project to integrate test and factor theory with the empirical, functional relationships involving standard intelligence tests. The project will render more objective the use of factor analysis in personnel research. A definition of intelligence…

The roles of (1) the sequence of instruction and (2) cognitive ability variables were investigated using a computer-assisted instruction (CAI) course on an imaginary science of "Xenograde systems." A rationale for an information processing task analysis was developed to overcome the deficiencies of other analytic methods. The new method was found…

Failure to consider errors of measurement when using partial correlation or analysis of covariance techniques can result in erroneous conclusions. Certain aspects of this problem are discussed and particular attention is given to issues raised in a recent article by Brewar, Campbell, and Crano. (Author)

The technique of factor analysis was used to explore the structure of five batteries of readiness tests (Gates Reading Readiness Test, Developmental Tests of Visual Perception, Metropolitan Readiness Tests, Specially Constructed Readiness Test by Olson, and Wechsler Intelligence for Children) as predictor variables for the Stanford Achievement…

The Class Activities Questionnaire (CAQ) was used to compare a Canadian high school participating in a research project employing an information retrieval system with another not involved in the project. This paper evaluates the validity of the CAQ as a measurement instrument for this study. The CAQ was administered to 1831 students, 806 Science…

Rationally defined outcome variables, for use in evaluating youth-work training programs, were incorporated in questionnaires administered to present and former Neighborhood Youth Corp enrollees and analyzed to determine their suitability as criterion measures. Using a factor analytic technique, empirically defined clusters were obtained for…

First grade students stratified on the basis of their racial-ethnic and socioeconomic status (SES) were studied to determine factors measured by several readiness (aptitude) tests and to learn whether these factors differed for the children from the various groups. SES was determined by father's occupation, or if absent, mother's occupation; the…

Statistical procedures are presented for determining ordinal and disordinal aptitude-treatment interactions with linear and curvilinear data. The paper presents a method for testing the homogeneity of group regressions for a single aptitude and provides models for expanding this test to linear and curvilinear regression planes. Procedures are…

The nature of the relations between traditional psychometric and Piagetian instruments is analyzed, in order to provide information relevant to the question of which type of test or combination of them will provide the most useful information to those seeking to construct and maintain optimal learning environments. Four hypotheses are posed: (1)…

A computerized content analysis of the "theory input" for a basic speech course was conducted. The questions to be answered were (1) What does the inexperienced basic speech student hold as a conceptual perspective of the "speech to inform" prior to his being subjected to a college speech class? and (2) How does that…

This document summarizes the authors ideas and ideas which were communicated during his meetings with various members of various national and international organizations. The purpose of these conversations was to study and evaluate the importance of the human factor which has determined the success of a demonstration farm at Vientiane and to…

An exploratory study of a prison community is presented. The study employed a three-phase design: (1) a pre-survey of the prison community, (2) limited intervention, based on findings of the pre-survey, and (3) a post-survey to determine effects of intervention and to validate findings of the pre-survey for which no intervention had been designed.…

The objective of the study was "to determine how the elementary school child evaluates his school environment through a comparison of the school as he sees it with how professional education intends it to be." The "Keys to Elementary School Environment," an instrument designed to measure the environmental press as perceived by elementary school…
