This study was designed to determine if the Cooperative School and College Ability Test (SCAT) can predict future college academic success of Negro college students with the same degree of accuracy as it does for white college students and to discover if the sex factor need be considered in making predictions. The sample consisted of 180 Negroes…

The two purposes of this study were: (1) to identify those factors that significantly affect the use of the science process skill of prediction, and (2) to construct and test a probabilistic equation, based on a competence-performance model of cognitive development that accounts for a child's performance on tasks involving the skill of prediction.…

The purpose of this study was to facilitate the development of relevant and valid modes of economic education for future needs of our society. The Delphi forecasting method operated through the submission and successive iteration of three rounds of questionnaires to a wide range of specialists in economics and education and of community economic…

This paper presents the description and several applications of a model which can be used to determine how long a researcher must wait for the return of completed mail questionnaires to be sure the data collected reflect the true values of the parameters of interest. This model proposes to fit two linear time trend lines to a set of mailed…

This paper suggests the applicability of metric multidimensional scaling for research within the political arena. Multidimensional scaling allows the researcher to simultaneously observe change and rates of change within the policy's attitudes toward the candidates and issues in election campaigns. Multidimensional scaling also reveals which…

Empirical results are presented as regards the implementation of a latent-trait psychometric model by means of conditional maximum likelihood estimation. Items are scored polychotomously into varying numbers of nominal categories and the test and item characteristic curves and information functions are examined. It is concluded that scoring items…

The Planning Unit is a concept employed in resource requirements forecasting for the public service agencies, as an alternative to the conventional hierarchical program-structure used in PPB systems. The planning unit concept allows analysts to generate cost analyses by several simultaneous program-structures, not all of which need be in a…

Educational and occupational status projections are conceptualized as mobility linked social psychological components of more general status attainment models. Limitations of such submodels are noted and a rationale is offered. Investigating the stability and reciprocal linkage of 2 status projection variables in a subset of a Southern Youth…

Described is an attempt to develop an instrument which could be useful in selecting teacher education candidates. A sample of 330 beginning teachers (100 elementary, 108 language arts/social science, and 122 mathematics/science) had responded to four self-report instruments (covering values, adjustment, practices, and attitudes). Their teaching…

The feasibility and effectiveness of a Bayesian method for estimating regressions in m groups is studied by application of the method to data from the Basic Research Service of The American College Testing Program. Evidence supports the belief that in many testing applications the collateral information obtained from each subset of m-1 colleges…

Since personnelmen (PNs) represent a major point of contact between the Navy and its enlisted men, the attitude a PN projects while performing his duties is believed to have an effect on his servicemen clients' satisfaction with the Navy and subsequent re-enlistment decisions. Because all rated servicemen must attend "A" school,…

The study explored relationships between aptitude test composites and final school grades in Air Force technical training for various cultural subgroups based on race, educational level, and geographical area of enlistment. Regressions of final school grade on an aptitude index were compared for the different subgroups in ten samples of technical…

The purposes of this conference are: to define the current state of technology; to identify the problems, needs and emerging technology; and to consider alternative computer applications to multiple-facility medical information systems for the delivery of medical care and for health services research. The papers presented include: (1) General…

This study examined relationships among conformity to biographical item writing rules, rated stability, and obtained response stability. First and second administration data were collected and a stability index was obtained on 88 items using a college freshmen sample (N=106). One group of judges then educed rules to discriminate between the more…

This paper evaluates the effects of two distinct modes of feedback to students. These two modes comprise: (1) predicted final course grade, and (2) current standing in class. The experiment was conducted with a final year class of 56 students attending a required half-year course in Educational Measurement. The class was divided into four…
