The paper contains a model of a technique for increasing the quality of educational and instructional opportunity for all students. This model is developed around the flexible or modularly scheduled secondary school. Also included is a procedure containing a computer program, with which the administrator can develop the master schedule of the…

In order to devise an aid for the teaching of formal languages and automata theory, a system was developed which allows a student to design, test, and change automata in an interactive manner. This process permits the user to observe the step-by-step operation of a defined automaton and to correct or alter its operation. Thus, the need for lengthy…

The primary objectives of this paper are pedagogical: to provide a reliable semi-subjective transformation procedure that might be used without difficulty by beginning students in factor analysis; to clarify and extend the existing knowledge of oblique transformations in general; and to provide a brief but meaningful explication of the general…

The logical structure of the Campbell and Fiske multitrait-multimethod approach is applied to the problem of studying growth and its determinants. The resulting model is a special case of Joreskog's general model for the analysis of covariance structures. The relationships of traditional psychometric formulations to this model are detailed.…

Intraclass correlation reliability estimates are based on the assumption that the various measures are equivalent. Joreskog's (1970) general model for the analysis of covariance structures can be used to test the validity of this assumption. (For related document, see TM 002 301.) (Author)

The purpose of this paper is to evaluate the causes of the apparent failure of black parents to pass their status advantages along to their children. The black-white differences in status transmission found by Duncan are discussed, explaining his findings by means of the Wisconsin model of status attainment. To explain the lesser dependence of the…

A general Computer program is described that will compute asymptotic standard errors and carry out significance tests for an endless variety of (standard and) nonstandard large-sample statistical problems, without requiring the statistician to derive asymptotic standard error formulas. The program assumes that the observations have a multinormal…

The Monte Carlo method was used, and the factors considered were (1) level of main effects in the population; (2) level of interaction effects in the population; (3) alpha level used in determining whether to pool; and (4) number of degrees of freedom. The results indicated that when the ratio degrees of freedom (axb)/degrees of freedom (within)…

Campbell (l969) argued for the interrupted time-series experiment as a useful methodology for testing intervention effects in the social sciences. The validity of the statistical hypothesis testing of time-series, is, however, dependent upon the proper identification of the underlying stochastic nature of the data. Several types of model…

This paper discusses discrepancies between the observable labor market and the idealized world which is assumed in theory. The proposed solutions are focused on the development of an empirical model applicable to data on prime-age males from the Michigan Panel Study of Income Dynamics, but the author notes that many of these issues are relevant…

Mathematical models have been used extensively to describe the judgmental processes and strategies of individual decision makers, but rarely have the procedures been extended to describe the judgmental strategies of decision-making groups. The present study attempts to extend the procedures for the purposes of describing group decision-making…

An econometric model is formulated that explains income per person in various compartments of the labor market defined by three main levels of education and by education required. The model enables an estimation of the effect of increased access to education on that distribution. The model is based on a production for the economy as a whole; a…

Reviews arguments for and against the use of analytical modeling systems in higher education and presents findings of a national survey of user perceptions of frequently used modeling systems: CAMPUS, PLANTRAN, RRPM, and SEARCH. Concludes greatest needs are for user education, feedback to model builders, and institutional commitment to…

Discusses the status of modeling efforts to predict impact of different educational access and support policies and identifies pitfalls involved in using simulation models for state and national educational planning. Concludes that few goals held for large-scale models have been achieved. Points up needs for improvement, e.g. more information at…

Noting the disappointing results of past experimentation with computer modeling technology in higher education, the author discusses developments which promise potential: communication between model builders and users, interaction between large- and small-scale models, interface with operating data systems, emphasis on outcomes, and continued…
