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)

Medical students (N=284) from four Northeastern medical schools interacted with standardized patients, then were given a free-response form (blank form for writing diagnostic impressions) and then they completed a cued-response form, which listed a series of diagnoses generated by the case author. The patients also completed a checklist. (MLW)

The extent that order effects in multiple-station clinical examinations are prevalent is addressed and an analysis of individual student score profiles pertaining to order effects is included. A clinical skills examination using standardized patients was administered to 157 medical students at the University of Illinois College of Medicine at…

A clinical law simulation exercise based on students testimony about events in their own lives was designed to train students as effective trial lawyers through direct and cross-examination, sensitization to the roles of other courtroom players, and consideration of social and ethical consequences of our trial methods.

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…

Describes an activity to simulate the geometries of a spreading pathogen such as HIV throughout a generation. Students exchange "bodily fluids" three times and are then tested for the presence of "infection." Materials used include base solutions (NaOH or KOH), phenolphthalein (pH indicator), clear plastic cups, and an eye dropper. (PR)

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)

Presents a classroom trial exercise in which student teams representing the plaintiff and defense provide calculations of economic damages. Argues that because the exercise replicates actual activities by economists in trial settings, it is a credible exercise for motivating economics students in general and pre-law students in particular. (DSK)

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)

Proposes the use of simulations to develop oral-language skills in the English-as-a-Foreign-Language classroom. Simulations allow students to interact in meaningful and realistic contexts and generate their own discourse. (Author/VWL)

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…
