Performance testing often entails the usage of expensive, time-consuming measures in the quest for determining the level of performance on some desired behavior. It is concluded that a generalizability theory approach to dealing with departures from reality in testing can aid in the establishment of empirically-based choices of measurement…

During the past few years the problem of bias in testing has become an increasingly important issue. In most research, bias refers to the fair use of tests and has thus been defined in terms of an outside criterion measure of the performance being predicted by the test. Recently however, there has been growing interest in assessing bias when such…

The report provides additional amplification for the concepts, purposes, techniques, and procedures of economic analysis. It also focuses on and discusses potential difficulties one is likely to encounter in doing an economic analysis. The key elements of the process are discussed in detail: (1) establishing and defining objectives, (2)…

This study, the fourth in a series of longitudinal studies, investigates causal and other relationships between leadership, teacher, and student variables in curriculum engineering. Measures were taken on leadership, teacher attitudes and performance, and student performance. A causal time-series model and path analysis were used to demonstrate…

Expertise in the technical aspects of planning and a keen appreciation of the social factors involved are not, in themselves, sufficient for satisfactory educational planning. The plan will still not be feasible unless there is attention to a third group of factors called "practical issues", "organizational features", or…

This paper addresses one element of the educational planning process -- the objectives to be attained as a result of the implementation. The authors first discuss objectives in the context of planning in general and the relationship of planning to the process of education. Within this context, the need for goal analysis is identified. Next, there…

Computer-assisted instruction (CAI) has become sufficiently widespread to require attention to the relationships between its costs, administration and benefits. Despite difficulties in instituting them, quantifiable cost-effectiveness analyses offer several advantages. They allow educators to specify with precision anticipated instructional loads,…

This report presents the methodology for short-run forecasting of personal income and employment in Hawaii. The econometric model developed in the study is used to make actual forecasts through 1973 of income and employment, with major components forecasted separately. Several sets of forecasts are made, under different assumptions on external…

The previous theoretical development of the Poisson process as a strong model for the true-score theory of mental tests is discussed, and additional theoretical properties of the model from the standpoint of individual examinees are developed. The paper introduces the Erlang process as a family of test theory models and shows in the context of…

This study was concerned with various schemes for reducing the number of variables in a multivariate analysis. Two sets of illustrative data were used; the numbers of criterion groups were 3 and 5. The proportion of correct classifications was employed as an index of discriminatory power of each subset of variables selected. Of the four procedures…

This document begins by defining and discussing educational planning. A brief overview of mathematical programing with an explanation of the general linear programing model is then provided. Some recent applications of mathematical programing techniques to educational planning problems are reviewed, and their implications for educational research…

In order to describe and predict career patterns of young men, this report provides: (1) Markov chains of the career patterns for four groups of 5,225 young men divided according to race and age, (2) tests of the predictive validity of the chains, and (3) comparisons of the four race-groups using the Markov models. Using the Holland occupational…

The final report summarizes accomplishments and implications of the project for the development and implementation of Navy training devices that utilize computer-based simulation. The emphasis is on Navy anti-air warfare in the shore-based training environment, but the results are applicable to other training environments. The report also…

A computer program for solving the conditional likelihood equations arising in the Rasch model for questionnaires is described. The estimation method and the computational problems involved are described in a previous research report by Andersen, but a summary of those results are given in two sections of this paper. A working example is also…

The model for educational measurement developed by George Rasch, a Danish psychometrician, is reviewed and its application to occupational educational testing discussed. The Rasch model is an adaptation from the theory of latent trait analysis. According to it, answering an item correctly is a function of the difficulty of the item and the ability…
