The rational model of classical economic theory assumes that the decision maker has complete information on alternatives and consequences, and that he chooses the alternative that maximizes expected utility. This model does not allow for constraints placed on the decision maker resulting from lack of information, organizational pressures,…

The chapters in this yearbook describe some of the experiences the individual authors have had in making and/or using multisensory aids in mathematics instruction. A number of different aids are noted to indicate the range of possibilities. Three more chapters set the stage for the remainder of the book which is divided into the following…

The survey reported on in this document addressed itself to discovering what kinds of quantitative models have been developed and implemented for educational decisionmaking during 1965-72, and what planning questions they are intended to answer; where these models have been implemented and to what extent they are being used; and the cost of such…

In this paper, the problem of choosing between education with the usual teacher-student interaction and television-assisted education is considered. The method used to select the alternative with minimum costs is presented, discussed, and applied to Botswana. (Pages 5 and 10 may reproduce poorly.) (Author)

Statistical methods are described for diagnosing and treating three important problems in covariate tests of significance: curvilinearity, covariable effectiveness, and treatment-covariable interaction. Six major assumptions, prerequisites for covariate procedure, are discussed in detail: (1) normal distribution, (2) homogeneity of variances, (3)…

The problem considered is that of an investigator sampling two or more correlation matrices and desiring to fit a model where a factor pattern matrix is assumed to be identical across samples and we need to estimate only the factor covariance matrix and the unique variance for each sample. A flexible, least squares solution is worked out and…

Production function applications to improve the efficiency of educational programs require identification of inputs and outputs and the establishment of a data bank to provide information on input and output variables. This generalizable input identification model organizes inputs for systems analysis at various levels of inputs and provides a…

The purpose of this paper is to describe the changing nature of educational planning and administration, thereby removing much of the semantic confusion surrounding these terms. At the same time, the authors emphasize the need for educational institutions to identify explicitly their objectives and activities in these two fields. The paper also…

The purpose of the study was to develop a linear programming model to be used for prediction, test the accuracy of the predictions, and compare the accuracy with that produced by curvilinear multiple regression analysis. (Author)

Contents of this book include: an introductory preface by C. Loring Brace; "Introduction to Jensenism," C. Loring Brace; "Can we and should we study race differences?" Arthur R. Jensen; "Intelligence in Black and White," Alexander Alland, Jr.; "Whose is the failure?" Vera John; "The influence of…

The Answer-Until-Correct (AUC) procedure has been proposed in order to increase the reliability of multiple-choice items. A model for examinees' behavior when they must respond to each item until they answer it correctly is presented. An expression for the reliability of AUC items, as a function of the characteristics of the item and the scoring…

This study was undertaken for the Center for Applied Linguistics to survey and analyze its information system program for the language sciences. The study identifies and defines the generalized sets of parameters required for subsequent quantitative analysis of proposed alternative Language Information Network and Clearinghouse Systems by means of…

Previous Studies have yielded mixed results concerning the relationships between student learning, instructor leniency, and student evaluations of instructors. A three-equation model is presented that disentangles learning from leniency and relates the results to evaluations. It indicates no significant relationship between either leniency or…

The Rasch Model was applied to the results of an academic self-concept test administered to junior high school students, and some items were eliminated. The resulting scale possessed several properties permitting its use in the measurement of school-induced change in self-concept. The questionnaire is appended. (Author/MV)

An application of confirmatory factor analysis, using the LISREL program, to retrospective analysis of rating data common in health professions education was illustrated. A causal model was specified and tested. Although most measures clustered around latent traits, there was more method variance in the data set than trait variance. (Author/JAZ)
