This case study describes a program of research that developed a new measure--the Adaptability Scale--and then tested this new measure through a set of substantive research questions and publications. Three phases of this research program are detailed: a measurement phase, a modeling phase, and a mediation phase. The aim of this case study is to…

The authors center their presentation of material around a conceptual understanding of psychometric issues, such as validity and reliability, and on purpose rather than procedure, the "why" rather than the "how to." Their goal is to introduce psychometric principles at a level that is deeper and more focused than found in introductory…

The Organisation for Economic Cooperation and Development's (OECD's) Programme for International Student Assessment (PISA) surveys, which take place every three years, have been designed to collect information about 15-year-old students in participating countries. PISA examines how well students are prepared to meet the challenges of the future,…

Discusses articles by Richard Rystrom in the Winter and Spring 1970 issues of the Journal of Reading Behavior. Questions the validation procedures and statistical evidence behind the author's model of reading comprehension. Tables and bibliography. (RW)

Performed confirmatory factor analyses on the standardization data for the Wechsler Intelligence Scale for Children and the Wechsler Intelligence Scale for Children (Revised) to test competing two- and three-factor hypotheses. Results slightly favored the three-factor solution, but must be weighed against the greater convenience of the two-factor…

In the present study, we reject the view that computer use can be studied as an isolated variable in a learning environment. Our main objective is to develop an instrumental tool to measure different types of educational computer use in the classroom. This builds on a comprehensive review of the literature about computer use in education. This…

Provides a conceptual basis for understanding factor analysis as an analytical technique. Illustrates the basic concepts of factor analysis through Edward L. Rainbow's data from a study of variables influencing students' musical aptitude. Suggests that this technique is most appropriate in music applications where the interrelationships between…

Lists six problems related to descriptive data and to factor analysis performed in a previous research study reported in this journal. Includes the authors' response to the suggested weaknesses of their study. (JN)

Reports on a series of methodological refinements used in developing a systematic rationale for the construction, standardization and interpretation of the Personal Health Survey (PHS), a 200-item questionnaire designed to screen pathological functioning in the psychophysiological support systems that underlie physical and mental health. The PHS…

Presents the history of psychometrics in terms of the various investigators who worked in this area; the fields of computer utilization, testing, scaling, factor analysis, and learning theory are examined. (JM)

Described here are methods being worked out, inductively, to convert to quantifiable factors a set of 144 personal interaction variables observed during individual testing of a multi-cultural sample of 50 high school students referred for school problems. Factor analyses of subsets of variables and comparison of correlations among "factor…

This study examined the effects of four characteristics of instructional objectives presented to the student prior to reading, upon intentional and incidental learning. The most salient result was produced by providing instructional objectives to the student prior to the text. The main findings were that (a) density increases (Proportion of…

This study of motivational differences in the school situation and the development of a sensation-seeking scale of preadolescent children rests upon an interactive psycho-biological theory formulated by Farley (1981). Stimulation-seeking and arousal in relation to instructional features are central concepts. As a point of departure for the…

THE THEME OF THIS PROGRAM WAS THE USE OF PROBABILISTIC MODELS AS MEASUREMENT TOOLS FOR EXPERIMENTAL DESIGN IN TEST CONSTRUCTION AND FOR ANALYSIS OF TEST DATA. SOME CENTRAL ISSUES IN THIS FIELD ARE DISCUSSED AND RESOLVED IN THE FIRST FOUR CHAPTERS OF THE REPORT UNDER THE FOLLOWING TITLES--(1) CONTRIBUTIONS TO ITEM SELECTION, (2) CLUSTERING…

The purpose of the investigation was to determine the construct validity of a standardized achievement test. The test, administered to over 5800 subjects, is one examination in a diploma program for students pursuing the Chartered Life Underwriter (CLU) designation. Results of factor and multiple discriminant analysis indicated the presence of…
