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).…

This article asks if testing can serve minority needs. The review suggests that testing can serve a useful purpose if it will help ensure quality to all students. (MFD)

The validity of Tinto's (1975) theory of student attrition, which asserts that withdrawal relates most directly to students' integration in the social and academic systems of an institution, is examined. This study supports that theory and also suggests that informal interaction with faculty plays an important role as well. (Editor/LBH)

Evaluated the Wechsler Intelligence Scale for Children-Revised (WISC-R) as a tool for understanding children's learning problems. Analyzed the predictive utility of several WISC-R subtest recategorizations with regard to academic achievement for 105 children referred for psychoeducational evaluation because of classroom learning problems. Stepwise…

Admissions criteria used for three classes of occupational therapy students were subjected to statistical analysis. Weighted factors included cumulative, science, and behavioral science grade point average, reading and mental ability test scores, and essay and interview scores. Revised factors eliminated the reading test and subject-specific grade…

A retrospective study was performed to determine whether graduates of a baccalaureate program in nursing who failed or were within a chance level of failure on the National Council Licensure Examination could have been identified as "risk" students during their undergraduate nursing program from data that are routinely collected.…

Examines the importance of levels of questioning and types of feedback in designing courseware for computer-based education. Test results are analyzed for four groups of high school students who completed different versions of a computer-based science lesson, and recommendations for future research are given. (Author/LRW)
