Examines the effectiveness of paper versions and computer versions of 10 ethical situations posed for student photojournalists. Finds that in-depth situations presented through computer software can give students more information on photojournalism ethics than 2-sentence scenarios on paper. (MS)

Results are reported from a study designed to determine whether computer-based teaching simulation could influence short- and long-term skill acquisition in 61 preservice teachers. Two factors (task realism and clear, immediate post-teaching feedback) are identified as significant contributors to the simulation's training success. (IAH)

An asymptotic expression for the reliability of a linearly equated test is developed using normal theory. Reliability is expressed as the product of test reliability before equating and an adjustment term that is a function of the sample sizes used to estimate the linear equating transformation. The approach is illustrated. (SLD)

Hierarchical Bayes procedures for the two-parameter logistic item response model were compared for estimating item and ability parameters through two joint and two marginal Bayesian procedures. Marginal procedures yielded smaller root mean square differences for item and ability, but results for larger sample size and test length were similar.…

One college teacher's use of mock trials in sociology instruction is described. Students are assigned roles as petitioner, respondent, attorneys, judge, courtroom staff, witnesses, reporters, and jurors. Pretrial investigations provide experience in information-gathering and critical thinking. Posttrial debriefing reveals others' thinking…

Presents the first stage in a research effort developing a detailed computational model of working memory. The central feature of the model is counterintuitive. It is assumed that there is a primacy gradient of activation across successive list items. A second stage of the model is influenced by the combined effects of the primacy gradient and…

Presents a one-day, integrated activity in which a class monitors several students simulating a NASA space-shuttle flight. Includes space-shuttle crew application and space-shuttle time line. (MKR)

Describes a computer program that can model the equilibrium processes in the production of ammonia from hydrogen and nitrogen, sulfur trioxide from sulfur dioxide and oxygen, and the nitrogen dioxide-dinitrogen tetroxide equilibrium. Provides information about downloading the program ChemEquilibrium from the World Wide Web. (JRH)

Basic procedures for performing computerized adaptive testing based on the successive intervals (SI) Rasch model were evaluated. The SI model was applied to simulated and real attitude data sets. Item pools as small as 30 items performed well, and the model appeared practical for Likert-type data. (SLD)

Reports on a trial simulation in which exposure to publicity regarding the defendant and general stories about acquaintance rape were manipulated; participants then viewed an enacted rape trial. Finds that male subjects exposed to predatory rape publicity were pro-defendant, whereas women were unaffected. Discusses male reaction to information…

Examines the advantages of presenting case study information via multimedia. Highlights identify advantages of using multimedia, including browsability, comprehensiveness, currency, flexibility, linkage, simplicity, precision, closeness to problem, and cost savings. Potential problems are also discussed. (Contains eight references.) (SLW)

Computer simulations indicate that the correlation between baseline and change, by itself, does not invalidate the use of gain scores to measure change, but when the negative correlation is accompanied by decrease in variance from pretest to posttest, covariance is a superior measure of change. (SLD)

Reviews the rationale for the use of simulation and game exercises as part of counselor education programs. Counselor competencies in the areas of knowledge, skills, and self-awareness are discussed; and the use of experience-based learning activities is explained, including the debriefing stage. (Contains three references.) (LRW)

Examines four working steps from an empirical model where an expert abstractor discovers what a paper is about and drafts a topic sentence; a simulation system is developed using this model. Discusses knowledge processing activities of professional summarizing. Results indicate that a small simulation model of professional summarizing is feasible.…

Discussion of the changing economic environment and the resulting restructuring of society focuses on changes in education needs. Highlights include evaluative simulations, interactive distance learning in the home and in the workplace using interactive media, and a list of World Wide Web information sources for distance education.
