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…

Examined several hypotheses about the suitability of the noncentral chi square in applied research using Monte Carlo simulation experiments with seven sample sizes and three distinct model types, each with five specifications. Results show that, in general, for models with small to moderate misspecification, the noncentral chi-square is well…

Describes an activity designed to demonstrate the birthday paradox and introduce students to real-world applications of Monte Carlo-type simulation techniques. Includes a sample TI-83 program and graphical analysis of the birthday problem function. (KHR)

Presents the design and implementation of a reliable multipeer protocol (RMPP), which is written in Java and is suitable for applications in the area of distributed virtual environments (DVEs). Discusses motivation, protocol classification, design goals and the error recovery algorithm and lists implementation issues. Presents two possible…

Estimates from a hazard model of college student departure for 3,975 students simulated how financial aid changes affect withdrawal decisions. Changing loans to scholarships has a large impact and front-loading aid (giving gift aid for the first 2 years) a modest impact on retention. Financial aid may represent more to students than its dollar…

A study of 46 management students compared three methods for learning strategic management: cases, simulation, and action learning through consulting projects. Simulation was superior to action learning on all outcomes and equal or superior to cases on two. Simulation gave students a central role in management and greater control of the learning…

A partnership between a university school of nursing and a health care information technology supplier resulted in the Simulated E-hEalth Delivery System (SEEDS). This program enables nursing students to learn clinical skills in a state-of-the-art environment using a live-production, clinical information system designed for care delivery. (JOW)
