Ackerman, Phillip L.; And Others – 1982
Statistical methods employed to test individual differences in dual-task performance and the existence of a general time-sharing ability are reviewed and critiqued. Specifically, both the types of data being collected and the types of data analysis procedures have been inadequate to the critical evaluation of a hypothetical…

Kingsbury, G. Gage – 1985
A procedure for assessing content-area and total-test dimensionality which uses response function discrepancies (RFD) was studied. Three different versions of the RFD procedure were compared to Bejar's principal axis content-area procedure and Indow and Samejima's exploratory factor analytic technique. The procedures were compared in terms of the…

Tatsuoka, Kikumi K.; Yamamoto, Kentaro – 1985
This study used the Montague-Riley Test to introduce a new scoring procedure that revealed errors in cognitive processes occurring at subcomponents of an electricity problem. The test, consisting of four parts with 36 open-ended problems each, was administered to 250 high school students. A computer program, ELTEST, was written applying a…

A method for statistical analysis of semantic differential data in educational evaluation is discussed. Estimated scores for unobserved affective variables are obtained using the canonical factor regression method. This method overcomes previous prolems of bias and inefficiency in computing composite affective indices. In an application of the…

Kaske, Neal K. – 1978
A number of sample inventories were conducted to measure the effectiveness of the Tattle-Tape book detection systems used in the Moffitt Undergraduate Library and the General Reference Services area of Doe Library, and to establish baseline data for missing materials in four branch libraries (Education-Psychology, Engineering, Environmental…

Molenaar, Ivo W. – 1978
The technical problems involved in obtaining Bayesian model estimates for the regression parameters in m similar groups are studied. The available computer programs, BPREP (BASIC), and BAYREG, both written in FORTRAN, require an amount of computer processing that does not encourage regular use. These programs are analyzed so that the performance…

Sorensen, Aage B. – 1978
This paper proposes a theory of the status attainment process, and specifies it in a mathematical model. The theory justifies a transformation of the conventional status scores to a metric that produces a exponential distribution of attainments, and a transformation of educational attainments to a metric that reflects the competitive advantage…

Kane, Michael T.; Brennan, Robert L. – 1977
A large number of seemingly diverse coefficients have been proposed as indices of dependability, or reliability, for domain-referenced and/or mastery tests. In this paper, it is shown that most of these indices are special cases of two generalized indices of agreement: one that is corrected for chance, and one that is not. The special cases of…

SAW, J.G. – 1964
THIS PAPER DEALS WITH SOME TESTS OF HYPOTHESIS FREQUENTLY ENCOUNTERED IN THE ANALYSIS OF MULTIVARIATE DATA. THE TYPE OF HYPOTHESIS CONSIDERED IS THAT WHICH THE STATISTICIAN CAN ANSWER IN THE NEGATIVE OR AFFIRMATIVE. THE DOOLITTLE METHOD MAKES IT POSSIBLE TO EVALUATE THE DETERMINANT OF A MATRIX OF HIGH ORDER, TO SOLVE A MATRIX EQUATION, OR TO…

Twenty-two papers and discussions presented at the 1979 annual meeting of the American Statistical Association are reproduced. Papers dealing with student evaluation of instruction include "An Analysis of Student Evaluation of Instruction and Relationships Among Salary, Chairman's Ratings, and Student Ratings of Faculty," by Alvin C. Rencher;…

Brennan, Robert L. – 1977
Rules, procedures, and algorithms intended to aid researchers and practitioners in the application of generalizability theory to a broad range of measurement problems are presented. Two examples of measurement research are G studies, which examine the dependability of some general measurement procedure; and D studies, which provide the data for…

Marshall, K. T.; Oliver, R. M. – 1979
The use of data on longitudinal student attendance patterns to determine variances, and hence confidence bounds, on student enrollment forecasts, in addition to finding the forecasts themselves, is demonstrated. The formulation of the enrollment model based on longitudinal student attendance patterns is described step by step, presenting the…

Stankard, Martin F., Jr.; Sisson, Roger L. – 1968
A model is developed which relates an index of school performance to management policy under a variety of environmental conditions. The process of education is defined by the qualitative concept that education is a process of communication. In the model development, the assumed relationships among the variables (factors controllable by management…

Moonan, William J. – 1974
The purpose of this paper is to lay a basis for and discuss the components of a system, called COMET, designed to objectively measure and evaluate the competency of trainees in military training enterprises. COMET is an acronym for "Computerized Objective Measurement and Evaluation of Trainees." These goals will be accomplished by: (a)…

Aims, Doug – 1971
A Markov model for predicting performance on criterion-referenced tests is presented,. The model is expressed mathematically as a function of transition matrix, a current state vector, and a future state vector. The matrix is defined in terms of conditional probabilities, i.e., the probability of making a transition to a specific future…
