A study investigated the performance of 6 successive medical school classes on 80 standardized-patient case examinations, looking for effects of student or standardized-patient gender on scores. Results showed no interaction of any practical consequence. Cases with gender-related concern (e.g., breast problems) also did not differentiate between…

A study investigated whether the more efficiently graded extended-matching questions were equivalent to short-answer questions in evaluating medical students' (n=98) ability to elicit physical findings and generate diagnoses and treatment plans, using standardized-patient examinations. The differences found in the two question types did not favor…

The University of Illinois' National Center for Supercomputing Applications, a cooperative effort of the National Science Foundation, University of Illinois, the state, and industry, offers training and support services in the use of technologically advanced computing for scientific research. The computers simulate physical phenomena that are…

Using simulated and real data, this study compares the performance of three methodologies for assessing unidimensionality: (1) DIMTEST; (2) the approach of Holland and Rosenbaum; and (3) nonlinear factor analysis. All three models correctly confirm unidimensionality, but they differ in their ability to detect the lack of unidimensionality.…

Describes results of a study of business school students that investigated the link between the ability of business simulation team participants to forecast financial and/or market-related outcomes and the actual results of their decision making. Profitability and forecasting errors are discussed, and implications for designing business…

The usefulness of a two-step version of the Mantel Haenszel procedure for distinguishing between differential item functioning (DIF) and item impact was studied by comparing the single-step and two-step procedures using a simulated data set. Results show changes in the identification rate for the two-step methods. (SLD)

Reviews the different types of models that can be used in groundwater modeling. Discusses the flow and contaminant transport models in the saturated zone, flow and contaminant transport in variably saturated flow regime, vapor transport, biotransformation models, multiphase models, optimization algorithms, and potentials pitfalls of using these…

Explains how training simulations can make on-the-job learning faster and safer by providing hands-on experience and controlled environments. Offers tips for assessing the costs and designing and effective simulation. (Author)

Describes a simulation exercise involving an imaginary organism in which students study the effect of predation on allele frequencies, examine the assumptions of the Hardy-Weinberg law, and consider whether the need to survive is a guiding force in evolution. Includes instruction for conducting the exercise. (MDH)

Argues that introductory texts in population geography overlook many important issues and current debates. Suggests that teaching population geography would benefit from reading and discussing Malthus' actual words; examining fertility dynamics and influences on reproductive choice; and considering gender issues. Presents a classroom activity to…

A media training program conducted for faculty and administrators at Seton Hall University (New Jersey) is described. The program has helped participants become more confident in speaking to media, enhanced the university's visibility, and built campus confidence in the public relations staff. Suggestions are made for selecting the target audience…

Describes several experiential-learning activities (three cultural-simulation games, a negotiation skills self-assessment exercise, and 20 rules for intercultural negotiation) that train students for intercultural business negotiations by helping them learn through experience how cultural clashes feel, and how they must be identified, understood,…

Discusses a case study on discovery learning with a computer simulation environment in the physics domain of collisions. Finds that providing assignments with the simulation improves students' performance on one aspect of an intuitive-knowledge test. Contains 43 references. (Author/WRM)

Describes Wavemaker, a simulation environment developed to graphically reveal the behavior of periodic systems using a series of increasingly sophisticated visual tools. Results indicate that the software is helpful in connecting real to simulated systems. (Author/CCM)

Reports on a study that examined the prior use of simulation on frog dissection in improving students' actual dissection performance and learning of frog anatomy and morphology. Finds that students who performed the simulation before dissection performed significantly better than students who performed dissection before using the simulation or…
