Reviews a HyperCard stack designed for use in schools and at home. Describes the program as primarily a database of information on Iraq, Kuwait, and the Gulf War. Contends that the program is pedagogically weak and of marginal use in the classroom. (CFR)

Describes the use of simulation to introduce the bootstrapping technique of creating confidence intervals for the mean, median, and variance. These bootstrap confidence intervals are compared to the traditional confidence intervals for the purpose of analyzing accuracy of the technique. A Minitab program to produce confidence intervals is…

A small-scale simulation investigated the impact of making essay topics available to test takers before the test. Results with 11 college students reveal little effect of the prepublished topic. Implications for teacher licensure examinations are discussed with reference to the Praxis Series: Professional Assessments for Beginning Teachers being…

Reports on two aspects of the SIMULATE (Simulation Authoring Tools Environment) project: an account of the learning processes that are involved in learning with computer simulations, and an inventory of learner attributes. Topics discussed include ISLEs (intelligent simulation learning environments), prior knowledge, motivation, cognitive style,…

The effects of priors and amount of bias in the Bayesian approach to the estimation problem in item response models are examined using simulation studies. Different specifications of prior information have only modest effects on Bayesian estimates, which are less biased than joint maximum likelihood estimates for small samples. (TJH)

Explains virtual reality as a computer-synthesized three-dimensional environment (cyberspace) in which human participants, appropriately interfaced, appear to be enveloped. Cyberspace in science fiction is discussed; contributions of aerospace and military simulation trainers, digital imaging, and motion picture special effects are described; and…

A detailed investigation is provided of Stout's statistical procedure (the computer program DIMTEST) for testing the hypothesis that an essentially unidimensional latent trait model fits observed binary item response data from a psychological test. Three refinements achieve greater power. The revised approach is validated using real data sets.…

The director of Northwestern University's Institute for the Learning Sciences describes software that creates simulated environments in which learners focus on skills rather than facts. Also addressed are learning motivation and learning style issues. (SK)

Discussion of integrating computer technology with the case-based approach for teaching school leadership focuses on an overview of project activities and initial findings of one funded multimedia research and development effort, the Administrator Case Simulation Project, to design, develop, and use CD-ROM case simulations as reflective thinking…

Discusses the use of virtual reality as an educational tool. Highlights include examples of virtual reality in public schools that lead to a more active learning process, simulated environments, integrating virtual reality into any curriculum, benefits to teachers and students, and overcoming barriers to implementation. (LRW)

Special education uses three types of computer-based instruction software: drill and practice, tutorials, and computer simulation. Assistive technology applications (electronic communication devices, voice-activated software, and print readers) are available for students whose disabilities do not allow them to perform functional tasks…

Discusses the use of constructive modeling and virtual simulation in team training; describes a military application of constructive modeling, including technology issues and communication protocols; considers possible improvements; and discusses applications in team-learning environments other than military, including industry and education. (LRW)

Highlights changes brought on by computers and technological advancement and notes that only those with a vision of the future can direct and participate in the evolution of education. Suggests that virtual reality, simulation, animation and other computer-based features will render traditional class learning futile and that computerized education…

A study investigated whether rotating three-dimensional objects using virtual reality would affect flexible thinking in 14 children (ages 8-11) with hearing impairments. Children played virtual 3-D Tetris individually, 15 minutes once weekly over 3 months. Before-and-after testing showed significantly improved flexible thinking in the experimental…

Describes a study that examined high school students' ethical reasoning in the context of their participation in a computer simulation of a workplace environment. Includes opportunities for ethical decision-making, classroom observation of participating students, and responses to hypothetical ethical dilemmas. (Author/LRW)
