Three computer simulations were conducted to show that very high aggregate predictive validity coefficients can occur when the across-case variability in absolute score stability occurring in both the predictor and criterion matrices is quite small. In light of the increase in internal consistency reliability achieved by the method of aggregation…

Although it is widely known that special assumptions are needed for univariate analysis of repeated measures data, researchers seldom examine their data for violation of these assumptions. This paper reviews ways in which repeated measures analyses are usually handled and describes limitations of these methods. A design with two within subject…

Intended for use with college students in introductory macroeconomics or American economic history courses, these two computer simulations of two basic macroeconomic models--a simple Keynesian-type model and a quantity-theory-of-money model--present largely incompatible explanations of the Great Depression. Written in Basic, the simulations are…

The procedure was to isolate the component variables and then to formulate the logical and mathematical rules governing their interaction. Students were classified by age, grade, and sex; also, their entry to, movement through, and graduation from the system were examined. (Author)

The index term input to three information retrieval systems has been analyzed in detail in order to form the input to a completely computerized simulation of an information retrieval system. The paper reports that, with certain reservations, index terms conform in general with the Bradford distribution. (Author)

A simulated chemistry experiment which has been programmed is described in detail. (Author)

The article contains a simulation-game which facilitates the study of political geographic aspects of guerrilla-type conflicts. The game can be used with high school and college students. (Author/RM)

A simulation model for use in library professional continuing education is described. (PF)

This study examines how closely the kernel equating (KE) method (von Davier, Holland, & Thayer, 2004a) approximates the results of other observed-score equating methods--equipercentile and linear equatings. The study used pseudotests constructed of item responses from a real test to simulate three equating designs: an equivalent groups (EG)…

A simulated chemistry experiment which has been programmed is described in detail. (Author)

To investigate the variables considered important to decisionmakers on an individual basis and within the natural context of the committee meeting, 110 members of 26 Committees on the Handicapped, and 102 members of ancillary professional groups responded to simulated case studies of hearing impaired children. Ss assigned the simulated cases in…

The paper examines current thoughts on leadership (specifically the works of James MacGregor Burns) and presents a simulation exercise developed as a practical application of Burns' model which can be used in secondary social studies classes for gifted students. Concepts of leadership and its development are addressed, as is the relationship of…
