Reviews evidence that children use diverse cognitive strategies; discusses the adaptive value of using diverse strategies; describes models of strategy choice based on rational calculations; and presents an overview of the distributions of associations model of children's strategy choice. (RH)

Investigates the value of applying principles derived from simulated annealing to clustering tuples in database design, and compares this technique with a graph-collapsing clustering method. It is concluded that, while the new method does give superior results, the expense involved in algorithm run time is prohibitive. (24 references) (CLB)

Establishes a theoretical basis for both understanding and testing the molecular level assumptions in mixtures. Considers activity coefficient models and equation of state mixing rules. (YP)

Described are analytical applications of the theory of random processes, in particular solutions obtained by using statistical procedures known as Monte Carlo techniques. Supercomputer simulations, sampling, integration, ensemble, annealing, and explicit simulation are discussed. (CW)

Student teams in a senior capstone course in marketing completed microcomputer simulation in which they developed six-month marketing plan for a new product. A procedure similar to Kelly's Role Repertory Test was applied to define the role that various information sources played in their decision-making process, a means of determining the amount…

This study investigated the distributional properties of the standardized residual that is commonly used in the Rasch model calibration program to develop various indices of item and person fit. The power of the standardized residual to detect measurement disturbances is also addressed. (TJH)

A computerized, simulation-based instrument, consisting of four community practice clinical scenarios, collected information-searching data and the students' decisions. The appropriateness of the decisions, assessed by three clinical judges, and the focus of information search, based on the computer-collected process data, were the dependent…

A year-long simulation of a single case supplements a traditional civil procedure course at Georgetown University. Experience with the approach suggests that design features can reduce the burdens on the instructor without reducing course effectiveness, making the approach feasible even with larger classes. (MSE)

Investigates the use of personal computer (PC) programs to help participants in simulation exercises transform their experiences into knowledge, skills, and attitudes. Six programs developed at Queensland Institute of Technology are described that involve operations management, strategic management, and macroeconomics. Examples of spreadsheets are…

Provides an overview of a graduate course on particulate processes, especially on crystal size distribution (CSD). Describes the course and includes a list of course topics. Discusses the CSD simulation and manipulation. (YP)

This article presents a rationale for development and implementation of computer based interactive videotape (CBIV) in preservice teacher education; identifies advantages of CBIV simulations over other practice exercises; describes economical production procedures; discusses implications and importance of these simulations; and makes…

Describes a simulation of OCLC's TAPECON retrospective conversion service and its impact on an online catalog in a large university research library. The analysis includes results of Library of Congress Card Numbers, author/title, and title searches, and hit rates based on an analysis of OCLC and locally generated reports. (three references)…

Compares two basic types of computer-based simulations--(1) variable-assignment simulations, and (2) diagnostic problem-solving simulations. Differences in the role of the computer, in the nature of the problem presented to the learner, and in the decision making required of the student are described. (eight references) (LRW)

A detailed description of a layered network model is provided, with computer simulations of key associative learning phenomena and predictions generated from the model. The model is compared to more conventional theories of learning to learn and configural learning. (SLD)

Reviews current research topics relating to computer simulations in German-speaking countries that emphasize problem solving and decision making. Topics discussed include the number of independent variables; studies that focus on personality characteristics; studies that focus on situational characteristics; and suggestions for further research…
