Covariance structures associated with linear structural equation models are discussed. Algorithms for computing maximum likelihood estimates (namely, the EM algorithm) are reviewed. An example of using likelihood ratio tests based on complete and incomplete data to improve the fit of a model is given. (SLD)

This study examined the impact of a biology course emphasizing computer simulation on student achievement and student attitudes toward science. The students in the experimental group were placed in a class limited to 16 students to have 2 students to each computer. (YP)

Discusses the history and development of gaming and suggests possible future developments. Highlights include models, simulations, and games; the use of games in the military, in social sciences, in business, and in education; the impact of computers on gaming; and the relationship among gaming, game theory, and social psychology. (LRW)

Discusses the effectiveness of the use of simulations and games as alternative approaches to learning. Criteria for evaluating games and simulations for use in the classroom are given, and steps involved in the design of simulations and nonsimulation games are described. (LRW)

Outlines a three-equation simulation model which can be used to explain different types of inflation. Demonstrates the use of the model in accomplishing instructional objectives. Supports the use of the model as a replacement for the mathematical tool commonly used by economists but beyond the abilities of students. (KO)

The effectiveness of computer simulation in enhancing learning of a health unit by 30 mildly learning-disabled high school students was investigated. Results indicate that computer simulation in combination with structured teaching was effective, particularly in the area of teaching problem-solving skills. (TJH)

Presents five K-six lesson plans for law-related education. Mock trials by Gallagher and Michael R. Morris demonstrate a small claims court and apply concepts learned in the study of the constitution. Robey Alonzo and Steve Jenkins outline a brainstorming exercise while Katherine Zuzula offers exercises to help students understand immigration…

Kanji City, a hypermedia program for teaching Japanese through trial-and-error exploration of a simulated real-life environment, is described. The possibilities for designing materials in hypermedia format, and the advantages of Hypercard's potential for integrating text with synthesized sound, interactive graphics, and animation are explored.…

Outlines an approach to teaching management control activities via the use of case study material, microcomputer technology, and commercially available software. A case study for use by an undergraduate class is described; it includes a single regression analysis, a spreadsheet model, and a description of the man/machine decision process.…

Describes the design principles of computer-assisted learning (CAL) environments in which the software is interactive yet adaptable to different styles of learning and teaching, illustrated with a mathematics application. Following implementation, initial evaluation data taken from students showed marked performance improvements, and indicated how…

This study investigated what constitutes exploratory learning and what effects instructional support measures have on it. Among the conclusions were that students were reluctant to apply learning processes that are considered characteristic for exploratory learning. Students had problems with the process, especially with the process of generating…

"The Guide to Simulations/Games for Education and Training" was the authoritative reference book for the field from 1970 to 1985. Describes technological developments and changes in the field and the four editions that were created as a result of those changes. (AEF)

Compares results of giving undergraduate students actual instructor feedback, computer-simulated instructor feedback, or no feedback. There were advantages to giving actual instructor-supplied feedback for exam performance, in-class responsiveness, and attitudes toward the instructor and other students. (JMV)

Discussion of the use of programming as a learning activity focuses on software-realized scaffolding. Emile, software that facilitates programming for modeling and simulation in physics, is described, and results of an evaluation of the use of Emile with high school students are reported. (Contains 95 references.) (LRW)

Discusses the implications of authentic activity as a model of learning, particularly in the design of computer-based simulations and project-based learning activities. Addresses the characteristics of problem-solving situations, educational simulations, and authentic learning activities; and identifies key guidelines in the design and development…
