Describes a problem-based course in developmental support communications sponsored by the Media Department of the British Council. Participants from developing nations learned to analyze problems in non-formal education, improve their decision-making, and plan, produce and evaluate materials for a specified audience. (Author/BD)

Describes a news conference simulation involving students from business communication classes and presentational speaking classes, which is used to prepare business students to "think on their feet" while under stress and facing a potentially hostile audience--conditions that business professionals are apt to encounter. (SR)

Presents a simulation that helps students understand the concepts of equilibrium and Le Chatelier's principle. (JRH)

Purdue University (Indiana) is developing a series of computer modules of state-of-the-art chemical engineering processes to serve as the basis for computer-simulated experiments. One, sponsored by Procter and Gamble, models the extraction step in the decaffeination process and allows students to determine the optimal extraction conditions for…

One-parameter (1PPC) and two-parameter partial credit (2PPC) models were compared using real and simulated data with constructed response items present. Results suggest that the more flexible three-parameter logistic-2PPC model combination produces better model fit than the combination of the one-parameter logistic and the 1PPC models. (SLD)

The utility of the three-form design coupled with maximum likelihood methods for estimation of missing values was evaluated. Simulation studies demonstrate that maximum likelihood estimation and multiple imputation methods produce the most efficient and least biased estimates of variances and covariances for normally distributed and slightly…

Describes the Financial System Simulator game, an Internet-based, interactive teaching aid that introduces undergraduate students to the domestic and international consequences of monetary policy. States that student surveys indicate the game keeps learners motivated and interested and helps them understand monetary policy. (JEH)

Proposes a microbial mystery activity to test students' knowledge of human anatomy and their ability to identify microbes. Provides an opportunity for students to develop logical deductive reasoning. Includes national science education standards related to this activity, activity sheets with whole procedures, and Internet resources. (KHR)

This article discusses the value of using fantasy and role playing games (FRPG) in the curriculum of gifted students. It lists ways that FRPG can supplement 26 academic subjects and develop 24 learning skills. Objections from religious groups to use of the games are addressed. Different types of games are compared.

Used computer simulations to examine effectiveness of different criteria for measuring infant visual habituation. Found that a criterion based on fitting a second-order polynomial regression function to looking-time data produced more accurate estimation of looking times and higher power for detecting novelty effects than did the traditional…

Describes how to lead students through a classroom-based simulation to teach a variety of concepts such as X-linked traits, sex determination, and sex anomalies. The simulation utilizes inexpensive materials such as plastic eggs that twist apart to represent human eggs and sperm. (AIM)

Observations of and interviews with a class of adult learners using an organizational behavior simulation explored how they applied difficult concepts within an ill-structured environment. Group competition inhibited communication and application of knowledge; in an atmosphere of trust, learners empower themselves, enabling articulation of…

Examines computer based simulations of practical laboratory experiments in engineering. Discusses the aims and achievements of lab work (cognitive, process, psychomotor, and affective); types of simulations (model building and behavioral); and the strengths and weaknesses of simulations. Describes the development of a centrifugal pump simulation,…

Proposes a mixture item response model for investigating individual differences in the selection of response categories in multiple choice items. A real data example illustrates how the model can be used to distinguish examinees disproportionately attracted to different types of distractors, and a simulation study evaluates item parameter recovery…
