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)

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,…

Describes how experiential learning provides a context for developing work readiness in primary grades. Discusses how the competencies outlined in the SCANS Report (resource use, interpersonal skills, information utilization, knowledge of work-related systems, and technological expertise) can be applied in early childhood education. Details the…

Describes an activity for primary students on bees. Demonstrates life in a beehive using students playing bees. Reports the effects of this activity on student learning. (YDS)

Describes an activity called the "Freedom Train": a simulation for eighth grade students that enables them to gain an understanding of the importance and dangers of the Underground Railroad. Explains that the project encourages students to work cooperatively while also reinforcing their research and map skills. Provides follow-up…

Addresses some of the issues associated with teaching chemical engineering design, specifically the capstone design sequence developed at the University of Dayton and the experience gained developing and teaching these courses. Discusses the pros and cons of chemical-process flowsheet-simulator use. (Contains 11 references.) (WRM)

Describes a course in international business writing that has been taught simultaneously since 1994 at institutions in Belgium, Finland, and the United States. Describes the course's three components: instruction; simulation, in which students exchange business documents internationally; and case studies of business people who communicate…

Pseudo-Maximum Likelihood (p-ML) and Asymptotically Distribution Free (ADF) estimation methods for estimating dynamic factor model parameters within a covariance structure framework were compared through a Monte Carlo simulation. Both methods appear to give consistent model parameter estimates, but only ADF gives standard errors and chi-square…

Describes a methodology for supporting exploratory learning that attempts to limit learning space, called exploration space, and adequately control the cognitive load learners would face in their exploration process. In Exploration Space Control (ESC) the extent of exploration space is controlled according to domain complexity, but also to…
