Compares the performance of 85 freshmen and sophomores enrolled in two sections of an online introductory networking and telecommunications course. One section utilized a network simulation package that allows the student to build and send data through different network configurations; the second section used a static network diagramming software…

Developed are simple recursion formulas for generating the exact distribution of the longest run of heads, both for a fair coin and for a biased coin. Discusses the applications of runs-related phenomena such as molecular biology, Markov chains, geometric variables, and random variables. (YP)

In a few select high schools in the U.S., supercomputers are allowing talented students to attempt sophisticated research projects using simultaneous simulations of nature, culture, and technology not achievable by ordinary microcomputers. Schools can get their students online by entering contests and seeking grants and partnerships with…

Describes how to enhance the benefits of using the Carmen Sandiego educational software programs by building in generous amounts of creative fun and writing activities. Discusses journal writing, character sketches, letter writing, writing a book, and report writing. (RS)

Discussion of educational games that can be configured to accommodate changes in the structure of the game focuses on MANAGEMENT 500, a microcomputer-controlled prototype business simulation game. Three modes of learning that can be emphasized through a configurable simulation game are explained: learning by discovery, by perseverance, and by…

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)

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…

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…

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…
