A set of Tests of Scientific Thinking were developed for possible use as criterion measures in research on creativity. Scores on the tests describe both quality and quantity of ideas produced in formulating hypotheses, evaluating proposals, solving methodological problems, and devising methods for measuring constructs.

Generalizability theory is used here to separate the ratings of courses by students into various components. Results indicate reliable findings when generalizing over students and items (to rate teachers and courses), and over students, items and courses (to rate teachers). (JKS)

This study reports the progress in developing and validating an instrument that can be used to measure critical aspects of a parent's attitudes and behavior that influence child development. This instrument should aid in reaching the goal of treating participants in parent education programs as individuals. (Editor/KC)

Describes the development of a standardized achievement test for high school horticulture students and analyzes resulting data from 37 high schools. Although the sample may not have been truly random, the test is felt to be sufficiently reliable and valid for use as a research and evaluation tool. (MF)

The test-retest reliability of criteria often used in diagnosing brain damage through the use of children's drawings was found to be low. A review of the literature showed different opinions on what drawing characteristics were indicative of brain damage. Low test-retest reliabilities may explain the variations in the literature. (Author/GDC)

Five studies are presented describing the development of a self-report inventory for measuring individual differences in learning processes. Factor analysis of items yielded four scales: Synthesis-Analysis, Study Methods, Fact Retention, and Elaborative Processing. There were no sex differences, and the scales demonstrated acceptable reliabilities…

The article describes the circumstances leading to the development of the Illinois Test of Psycholinguistic Abilities and discusses the malpractices in administration, scoring, and interpretation of the test. (Author)

For a sample of seven and eight-year old Nigerian elementary pupils, validity coefficients of a modified matrix completion instrument entitled Modified Hall's Matrices, were determined relative to two achievement tests. The coefficients were quite high. (Author/JKS)

The early development of the Academic Motivations Inventory, a self-report measure of the academic motivations of college students, is described. Validation and reliability studies suggest that, at present, the instrument could be used to assess motivation of a group or class of students, but not yet as individuals. (Author/JKS)

Test-retest item instability indices for low, middle, and high scores on the Piers-Harris Children's Self-Concept Scale were calculated in order to test the hypothesis that low scores are invalid because of unreliability of responding. The hypothesis was not supported. (Author/JKS)

The psychometric application of Joreskog's procedure for simultaneous factor analysis in several populations is illustrated. Using Scholastic Aptitude Test data from two samples, procedures are shown for checking test construction assumptions about units of measurement and error variance, within and between samples. (Author)

An eighteen-item scale designed to indicate a relative, absolute, or mixed philosophical orientation to the nature of reality was related to a variety of other measures on a sample of community college students. Results indicate relationships among some measures with the scale. (Author/JKS)

Assessment procedures and psychometric properties of an instrument used to measure psychological well-being in black adolescents are described. The How I Feel test, presented in an audiovisual format, reliably and validly measures several multi-item constructs representing psychological well-being. Two major components are self esteem and…

The diversity among interpretations of single items in personality questionnaires has been noted previously. Using adjectives from the Adjective Check List (ACL), the study sought evidence bearing on these questions: Does such diversity make the responses to an item not comparable across subjects? If so, what are the implications for scores based…

Differential Aptitude Test (DAT) scores of 2,622 students who were tested in the 8th, 9th, or 10th grades and who later entered a Minnesota area vocational-technical school were analyzed to determine the relationships between test scores and training program entered. Results are presented. (Author)
