The evolution of a computer program that plays a game involving dice is described. The overall strategy was improved by introducing skill levels. (MP)

Utopolis, an imaginary community, was created by 48 fourth, fifth, and sixth grade students. Given only geographical boundaries, the group created the town complete with its many complex and interrelated problems. (NQ)

Identifying employees with management potential is just one of the many uses of an assessment center. (For availability, see EA 507 433.) (Author)

A simulation was designed and evaluated that permitted teacher trainees to experiment with varied conditions of specificity of objectives. Findings indicated that effects of the simulation could be replicated and trainees' statements concerning the value of objectives could be affected in favor of specific objectives. (Author)

Discusses the use of engineering case studies to prepare students to define and solve the open-ended problems characteristic of engineering practice. (MLH)

Deals with decision-making in the light of monetary values, with emphasis on minimizing educational losses. (Author)

The simultaneous assessment of differential item functioning (DIF) for a collection of test items through an index that measures the variance of DIF on a test as an indicator of the degree to which different items show DIF in different directions is proposed and evaluated through simulations. (SLD)

Sample covariance matrices constructed with pairwise deletion for randomly missing data were used in a simulation with three sample sizes and five levels of missing data (up to 50%). Parameter estimates were unbiased, parameter variability was largely explicable, and no sample covariance matrices were nonpositive definite except for 50% missing…

Describes a DNA fingerprinting simulation that uses vegetable food coloring and plastic food containers instead of DNA and expensive gel electrophoresis chambers. Allows students to decipher unknown combinations of dyes in a method similar to that used to decipher samples of DNA in DNA fingerprint techniques. (JRH)

Presents a genetics simulation that uses a noncomputer version of BioQUEST's Genetics Construction Kit. Provides students with opportunities for solving realistic genetics problems and allows them to experience how classical geneticists think. Discusses the problem's search space, thinking qualitatively, hypothesis generation and testing, thinking…

Business policy students (n=80) participating in a business simulation game were able to apply their classroom learning. Their satisfaction was not determined solely by game attributes; locus of control, achievement need, risk propensity, and satisfaction with their group were influential factors. (SK)

Presents efforts in exploring new ways for designing innovative pedagogical scenarios to support learning about complex domains that involve the design of interactive learning environments (ILE) to integrate systems supporting alternative ways of interaction with simulations with an emphasis on support for shared interaction to mediate social…

Presents empirically based item selection guidelines for moving the cut score on equated tests consisting of "n" dichotomous items calibrated assuming the Rasch model. Derivations of lemmas that underlie the guidelines are provided as well as a simulated example. (SLD)

Developed two methods for estimating the individual level correlation coefficient that combines information from aggregate data with a small fraction of the individual level data. Results of a simulation study support the use of these methods. (SLD)

Proposes a new approach (random strategy criterion) for measuring the internal validity of simulation game participation that offers a more logical conceptual foundation than past research approaches. Results of classroom testing with 660 undergraduate marketing students supports the use of random strategy criterion for measuring internal…
