This report was prepared in response to a request for information on supercomputers and high-speed networks from the Senate Committee on Commerce, Science, and Transportation, and the House Committee on Science, Space, and Technology. The following information was requested: (1) examples of how various industries are using supercomputers to…

This military history board game can be used as an extracurricular, extra credit, or classroom incentive project. The game serves to quantify an historical event so that it enriches the study of history for both verbally and mathematically inclined students. Although most suitable for eighth grade and above, the game may be played by some younger…

This paper discusses methodologies which allow in-depth exploration of usage patterns and preferences in screen-based computer-mediated communication (CMC). The paper, which focuses on usage by the general public, is divided into five parts. The first part discusses the growth trends and special characteristics of CMC in comparison to other…

Related to the earlier ACT production system theory, this book's basic goal is to present evidence for the psychological reality of a production system model of mind. Distinguished from the original theory in three ways, this volume uses previous rational analyses to improve upon that theory and extend its scope. It also relates the theory to new…

Half of New York State's 50 school-to-work (STW) programs are in rural areas. Following background on the development of New York's STW initiative, this paper describes four programs that are overcoming rural barriers to building an STW system. The GLOW Partnership addressed a primary concern of business partners: over-saturation of the limited…

Designed to introduce concepts in international trade and global economics to upper elementary and secondary level students, this simulation activity engages students in the group task of assembling flashlights. A variety of topics can be explored, such as energy shortages, international crises, relationships between rich and poor nations, foreign…

The empirical performance of the technique proposed by P. O. Johnson and J. Neyman (1936) (the JN technique) and the modification of R. F. Potthoff (1964) was studied in simulated data settings. The robustness of the two JN techniques was investigated with respect to their ability to control Type I and Type III errors. Factors manipulated in the…

This paper presents the results of a study on the effects of using 3 simulators with 14 computer science majors enrolled in an undergraduate computer architecture course. Three ability groups (high, medium, and low) were formed based on the students' quality point averages for prior computer science courses. Analyses of data from a pretest, a…

The performance of the following four methodologies for assessing unidimensionality was examined: (1) DIMTEST; (2) the approach of P. W. Holland and P. R. Rosenbaum; (3) linear factor analysis; and (4) non-linear factor analysis. Each method is examined and compared with other methods using simulated data sets and real data sets. Seven data sets,…

A part-form methodology was used to study the effect of varying degrees of multidimensionality on the consistency of pass/fail classification decisions obtained from simulated unidimensional item response theory (IRT) based licensure examinations. A control on the degree of form multidimensionality permitted an assessment throughout the range of…

In this paper a quadratic curve equating method for different test forms under a random-group data-collection design is proposed. Procedures for implementing this method and related issues are described and discussed. The quadratic-curve method was evaluated with real test data (from two 30-item subtests for a professional licensure examination…

This report reflects research and development on visualization and the use of multimedia carried out at the Department of Applied Education, Division of Instrumental Science and Technology of the University of Twente (Netherlands) and the Andersen Consulting Educational Computing Consortium, also at the University of Twente. The report contains 11…

The purpose of the training model described in this paper is to provide proactive and intervention strategies for managing classroom conflict. The impetus for the creation of this model came from a workshop collaboratively developed by high school students, teachers, and university faculty. The training model is designed for both prospective and…

This introduction to computer simulations as an integrated learning experience reports on their use with students in grades 5 through 10 using commercial software packages such as SimCity, SimAnt, SimEarth, and Civilization. Students spent an average of 60 hours with the simulation games and reported their experiences each week in a personal log.…

Mathematics problem solving skills need to be developed through meaningful interactions. Computer simulations combined with cooperative learning methods provide students a context within which to construct an understanding of mathematics problem solving. This study examines the distribution and sequence of events that result in acquisition of…
