In order to determine if there are differences in the work values of two-year college students among various vocational/occupational majors, Super's Work Values Inventory was administered to 391 freshmen entering Middlesex Community College in the fall of 1973. Among the 127 males and 268 females surveyed, there were 178 liberal arts majors, 73…

Employed were a small sample of fifth graders to examine techniques for assessing the validity of psychosocial maturity (PSM) and the scales used to measure it. Three validation techniques were examined: (1) Data obtained from self-report scales, teacher ratings, and peer ratings were used to generate three multitrait-multimethod matrices (total…

The purposes of this research project are (1) to test a theory which purports to identify the predictive antecedents (i.e., precursors) of developmental dyslexia (specific reading disability) several years before the disorder is clinically evident, and (2) to evaluate the mechanism which is postulated to underlie and influence later developmental…

Research conducted during the two earlier phases of this study showed a definite correlation between certain knowledges, abilities, and aptitudes, and success in the trade machine shop and trade electrical shop programs. On the basis of this and other research and experience, this study sought to develop reliable evaluative instruments and…

This study evaluated the Minnesota Multiphasic Personality Inventory (MMPI) as a predictor of employment status with male, physically handicapped vocational rehabilitants of employable age who had been patients at centers at the University of North Dakota and the University of Minnesota; and compared Katzell's Double Cross-Validation (DCV) with a…

An aptitude battery was validated against a Job Knowledge Test to determine if aptitude tests are culturally biased when used to predict occupational success. 287 white and 168 Negro Medical Technicians completed an eight test experimental aptitude battery and a Job Knowledge Test developed as a criterion measure of job performance. Linear…

Research examined the relative desirability of categories of information supplied by a keysort search procedure, as judged by users. The Career Information System was used as the framework for obtaining occupational information organized around the concept of the Worker Trait Group (WTG). Four groups of students in each of grades 9 through 12…

This paper offers a preliminary analysis of the effects of a semi-segregated school system on the IQ's of its students. The basic data consist of IQ scores for fourth, sixth, and eighth grades and associated environmental data obtained from their school records. A statistical model is developed to analyze longitudinal data when both process error…

From some simple and schematic assumptions about information processing, a stochastic differential equation is derived for the motion of a student through a computer-assisted elementary mathematics curriculum. The mathematics strands curriculum of the Institute for Mathematical Studies in the Social Sciences is used to test: (1) the theory and (2)…

Differential prediction of grade point average for black and white freshman students was empirically investigated at 13 integrated institutions by comparison of regression planes. Particular attention was given to the possibility that prediction procedures that are appropriate for white (majority) students would under-predict the performance of…

The development of a Student Rating Form to be used by faculty in systematically describing college students is outlined in this first of a series of reports concerned with faculty characterizations of students. The treatment is primarily historical, providing a basis for subsequent technical reports of analyses of faculty definitions of desirable…

This text was developed on an autoinstructional basis to familiarize the reader with the various interpretations of reliability and validity, their measurement and evaluation, and factors influencing their measurement. The text enables those with prior knowledge of statistics to increase their understanding of variance and correlation. Review…

The purpose of this study was to attempt to identify those factors that influence a high school student's success on the Advanced Placement (AP) Examinations by examining and comparing the variables contained in the high school records of former AP participants. A total of 248 high school students participated in the research. The criterion for…

Alternate admission systems are reviewed in respect to the minority applicant in an attempt to assess the nature of the bias frequently referred to in connection with standardized testing. The connection between the use of the Graduate Record Examinations (GRE) as a standardized test and the admission system was explored, concluding that the role…

This article presents predictive validity data for on-job performance for a set of computerized Graphic and Interactive Processing (GRIP) tests in conjunction with data for both experimental paper-and-pencil and operational tests. Validity coefficients for job element and global criteria are reported for four different jobs. (See also EJ 161 400).…
