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)

The rank transformation approach to analysis of variance (ANOVA) as a solution to the Behrens-Fisher problem was examined. Using simulation methodology, four parameters were manipulated for the two-group design: (1) ratio of population variances; (2) distribution form; (3) sample size; and (4) population mean difference. As a general solution to…

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 predicted scores produced by regression with (1) single best predictor, (2) two best predictors, (3) all predictors with observed values, and (4) all predictors with or without observed values were compared with variable means as estimates of missing values. The study was conducted in a simulation mode on nx8 data matrices using various levels…

The notion of buggy procedures has played an important role in recent cognitive models of mathematical skills. Some earlier work on student modeling used artificial intelligence methods to automatically construct buggy models of student behavior. An alternate approach, proposed here, draws on insights from the rapidly developing field of machine…

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…
