The impact of detailed information on closed head injury (CHI) and Minnesota Multiphasic Personality Inventory-2 (MMPI-2) validity scales on malingering psychological symptoms of CHI on the MMPI-2 was studied in an analog experiment with 270 undergraduates. Results suggest the impact of such coaching on simulation of CHI. (SLD)

Examines two methods of conducting an employment interviewing training exercise for interviewees. Compares instructor-facilitated and peer-facilitated exercises specifically. Discusses the advantages and disadvantages of each. Concludes that instructor-facilitated training was preferred over peer-facilitated training, and suggests directions for…

British high school students (n=120) participated in a management exercise in which teams prepared a marketing contract, drafted a promotional leaflet in French, and gave a marketing presentation to hotel management. The exercise developed teamwork, decision making, and leadership, as well as other skills valued in the workplace: bilingualism,…

Discusses the current use of simulation and gaming in a variety of settings. Describes advances in technology that facilitate the use of simulation and gaming, including computer power, computer networks, software, object-oriented programming, video, multimedia, virtual reality, and artificial intelligence. Considers the future use of simulation…

This document describes the construction/simulation software called Stella which can be used in the investigation of dynamic causal models. Topics considered are its built-in perspective of system dynamics and capabilities, its potential drawbacks, and its cognitive implications for educational applications. (JJK)

This report describes a dental model technique used at the Academy of Health Sciences, Fort Sam Houston, Texas. The technique uses Dentoform which provides a realistic set of Ivorine plastic teeth set in rubber "gingivae" upon which operative dentistry, prosthodontics, and limited periodontal scaling can be practiced. (GLR)

Describes an activity for use with a chapter on dinosaurs, prehistoric life, or digestion in which children make simulated dinosaur stomachs to gain hands-on experience about the theory of gastroliths, or stomach stones. Presents teacher information about the digestive processes in birds and dinosaurs. Discusses materials needed, objectives,…

Examines reasons for cataloging backlogs in libraries and describes a preliminary theory of backlog dynamics. Formulas for predicting backlogs are discussed, backlog models are explained, the use of computer simulation software to form models is described, and further research is suggested. (five references) (LRW)

Describes algorithms used in the computer program LOGIMO for obtaining maximum likelihood estimates of the parameters in loglinear models. These algorithms are also useful for the analysis of loglinear item-response theory models. Presents modified versions of the iterative proportional fitting and Newton-Raphson algorithms. Simulated data…

Reviewed transition to work life literature and interviewed 5 youth counselors and 14 youths regarding their views of transition process, barriers to successful transitions, characteristics of successful transitions, and meaning of work. Both groups consistently identified employment skills, employer characteristics, and social support as…

Contrasts modeling methods in control theory to the methods of statistical generalizations in empirical studies of human or animal behavior. Presents a computer simulation that predicts behavior based on variables (effort and rewards) determined by the invariable (desired reward). Argues that control theory methods better reflect relationships to…

An adaptive testing algorithm is presented based on an alternative modeling framework, and its effectiveness is investigated in a simulation based on real data. The algorithm uses a latent class modeling framework in which assessed latent attributes are assumed to be categorical variables. (SLD)

The importance and value of modeling in physics teaching is discussed from two different points of view: to teach physics as it is nowadays practiced; and to take into account research into cognitive science and learning. Two kinds of modeling software are briefly described. (40 references) (Author)

Investigates the BILOG computer program's ability to recover known item parameters for different numbers of items, examinees, and variances of the prior distributions of discrimination parameters for the two-parameter logistic item-response theory model. For samples of at least 250 examinees and 15 items, simulation results support using BILOG.…

Kernel smoothing methods for nonparametric item characteristic curve estimation are reviewed. A simulation with 500 examinees and real data from 3,000 records of the Graduate Record Examination illustrate the rapidity of kernel smoothing. Even when population curves are three-parameter logistic, simulation suggests no loss of efficiency. (SLD)
