Provides an overview of issues concerned with the design and use of computer-based simulations. Learning processes are discussed, and the SIMULATE project, which was developed to design an integrated set of authoring tools for the construction of an intelligent simulation learning environment (ISLE), is described.

Experimentally examines reorganization, a fundamental component of William T. Powers' theory of mind based on the control theory of behavior. Attempts to model reorganization, focusing on improvements in performance with practice and how practice influences attention. Speculates how outputs from higher levels of the control hierarchy are involved…

Discussion of discourse created by computers defines discourse as a pattern of cognitive functioning and identifies two such modes of thought: narrative and expository. Discussion covers the computer as discourse; schemas as a way to understand how knowledge is organized; simulations, hypermedia, and databases as discourse; and interactive…

Describes a computer simulation, CACTUS, that was developed in the United Kingdom to help police with command and control training for large crowd control incidents. Use of the simulation for pre-event planning and decision making is discussed, debriefing is described, and the role of the trainer is considered. (LRW)

Describes TECH 2000, a permanent gallery of interactive multimedia applications contributed by manufacturers and producers of multimedia systems. Located in Washington, DC, the gallery includes examples of multimedia technology in the areas of arts and culture, new technology, interactive training, educational tutorials, community information,…

A mechanical analogy between the microscopic motion of a charged carrier in an ordinary resistor and the macroscopic motion of a ball falling along a slanted board covered with a lattice of nails is introduced. The Drude model is also introduced to include the case of inelastic collisions. Computer simulation of the motion is described. (KR)

Describes accomplishments of the Global Systems Analysis and Simulation (GLOSAS) project from 1973 to the present, including a system for global peace gaming. The capabilities of interactive multimedia to link people across political and geographic boundaries for joint study, debate, research, planetary problem solving, and political action are…

Discussion of virtual reality (VR) focuses on the promise that VR offers for information systems by describing current systems which use VR and by projecting possible developments for the future. Types of information problems which could be helped by VR are considered, as well as those that could not be helped. (Contains 13 references.) (LRW)

Considers the role and effectiveness of virtual reality in simulation-based training. The theoretical and practical implications of verity, integration, and natural versus artificial interface are discussed; a three-dimensional classification scheme for virtual reality is described; and the relationship between virtual reality and other…

Three heuristic methods of assessing the dimensionality of binary item pools were evaluated in a Monte Carlo investigation. The indices were based on (1) the local independence of unidimensional tests; (2) patterns of second-factor loadings derived from simplex theory; and (3) the shape of the curve of successive eigenvalues. (SLD)

A method is presented for estimating the item characteristic curve (ICC) using polynomial regression splines. Estimation of spline ICCs is described by maximizing the marginal likelihood formed by integrating ability over a beta prior distribution. Simulation results compare this approach with the joint estimation of ability and item parameters.…

Describes a computer-assisted simulation that was used to improve foreign language learning among engineering and teaching students. The use of telecommunications is discussed; the foreign policy orientation of the simulation is described; and the positive effects of the simulation on student motivation, independent learning, and cooperation are…

In a simulation study, factor analysis and multidimensional item response theory (IRT) models are compared with respect to estimates of item parameters. For multidimensional data, a common factor analysis on the matrix of tetrachoric correlations performs at least as well as the multidimensional IRT model. (SLD)

Described is the author's decision to help a student find alternatives to performing several terminal experiments on animals in a college physiology class. Replacement exercises used for studying the properties of muscle types are described. Details about the difficulties and successes of the entire experience are reported. (KR)

Reviews the development and the principal elements of total quality management (TQM) and demonstrates methods for introducing some of the key elements into a strategy-oriented business simulation game that can be used to teach future managers. Topics discussed include increased focus on the customer; continuous improvement; and competitive…
