Definitional questions are raised first, followed by discussion of simulations and their place in the mathematics classroom. Variety and classification are discussed, plus some comments on designing simulations. (MNS)

Describes a computer simulation program which helps students learn the main biochemical tests and profiles for identifying medically important bacteria. Also discusses the advantages and applications of this type of approach. (ML)

Investigates whether the hypothesis that the mother's work situation influences parents' perceptions of their three-year-old children can explain reported differences in effects of maternal employment on the child. The sample consisted of 152 white, two-parent families. Results support the generalization that maternal employment may entail both…

The Search of Associative Memory (SAM) model for recall is extended by assuming that a familiarity process is used for recognition. The model, formalized in a computer simulation program, correctly predicts a number of findings in the literature as well as results from an experiment on the word-frequency effect. (Author/BW)

Demonstrating petroleum engineering concepts in undergraduate laboratories often requires expensive and time-consuming experiments. To eliminate these problems, a graphical simulation technique was developed for junior-level laboratories which illustrate vapor-liquid equilibrium and the use of mathematical modeling. A description of this…

Describes five categories of computer programs useful for content area reading instruction: utility programs, word processing, simulations, telecommunications for access to a database, and story architecture. (HOD)

The EM algorithm is used to derive maximum likelihood estimates for item parameters of the two-parameter logistic item response curves. The observed information matrix is then used to approximate the covariance matrix of these estimates. Simulated data are used to compare the estimated and actual item parameters. (Author/BW)

Description of encoding of art works and digitization of paintings to preserve and restore them reviews experiments which used chromatic selection and abstraction as a painting restoration method. This method utilizes the numeric processing resulting from digitization to restore a painting and computer simulation to shorten the restoration…

Describes and lists a program for Apple Pascal Version 1.1 which investigates the behavior of the bicarbonate-carbon dioxide buffer system in acid-base disorders. Designed specifically for the preclinical medical student, the program has proven easy to use and enables students to use blood gas parameters to arrive at diagnoses. (DH)

Describes and reviews commercially-available computer software for social studies (SS). They are: "Jury Trial II" (utilizes artificial intelligence); "Africa" (utilizes creative graphics to teaching SS facts; "Revolutions: Past, Present and Future"; "The Other Side" (examines world peace using values…

Suggests new method of external distribution called tree partitioning that involves use of binary tree to split incoming file into successively smaller partitions for internal sorting. Number of disc accesses during a tree-partitioning sort were calculated in simulation using files extracted from British National Bibliography catalog files. (19…

Investigators have suggested that faculty attitudes toward diagnostic testing may encourage inappropriate laboratory use. Those attitudes were determined from case simulations prepared by the faculty for senior medical student examinations. Faculty indifference to tests with limited usefulness may be perceived by students as permission for their…

Seven possible applications of microcomputers in high school science programs are discussed. They include computers as calculators, computers as black-box number crunchers, computers for teaching computer literacy, computers as blackboards, computer-assisted instruction, computer simulations, and process control. (JN)

Discusses several ways in which computers are being used in sociology and how they continue to change this discipline. Areas considered include data collection, data analysis, simulations of social processes based on mathematical models, and problem areas (including standardization concerns, training, and the financing of computing facilities).…

Describes a computer-based Wilderness Travel Simulation Model that reduces the complexity of the outdoor system under study, allows students to act as managers (devising and testing their own management strategies), and increases student exposure to characteristics of actual park and wilderness areas. Two scenarios of recreational use patterns are…
