States that teaching the concepts of evolution to secondary school and college students is difficult. Presents a playing card game-based simulation that teaches the complex idea of natural selection in a simple, nonthreatening way. Includes three figures, one table, and step-by-step instructional procedures. (CFR)

Describes an instructional simulation of a commercial banking system. Identifies the teaching of portfolio theory, market robustness, and the subtleties of institutional constraints and decision making under uncertainty as the project's goals. Discusses the results of applying the simulation in an environment of local and national markets and a…

Extensions of unidimensional appropriateness indices are developed for multiunidimensional tests (multidimensional tests composed of unidimensional subtests). Simulated and real data (scores of 2,978 students on the Armed Services Vocational Aptitude Battery) were used to evaluate the indices' effectiveness in determining individuals who are…

W. M. K. Trochim and others defend the record of the regression-discontinuity (RD) design and blur the statistical tests for treatment effect. Their Monte Carlo results show the problematic nature of RD and its potential bias. New testing strategies and restrictions for the application of RD are proposed. (SLD)

The validity of vignettes used to elicit subject responses in social science research is examined in a study of the validity of a group of patient assault vignettes seen by 12 persons with experience in patient care. A model for establishing the validity of vignettes is proposed. (SLD)

Using a connectionist framework, it is possible to develop models exploring effects of biologically relevant variables on behavior. The ability of such models to explain schizophrenic behavior in terms of biological disturbances is considered, and computer models are presented that simulate normal and schizophrenic behavior in an attentional task.…

This study reports results of an investigation based on simulated data of the distributional properties of the item fit statistics that are commonly used in the Rasch model calibration programs as indices of the fit of responses to individual items to the measurement model. (SLD)

Factors that contribute to different perspectives and attitudes toward learning in both teachers and students are discussed, and MARKETING SIMULATION exercise for undergraduates at University of Lancaster is described. An evaluation of instructional effectiveness of this exercise is reported with emphasis on the impact of hidden curricula on…

This replication of a comparison of student perceptions and attitudes toward learning from case studies and from management simulations found that students perceive the simulation exercise to be superior to case study discussions for learning skills in the business policy course. Because these results contradict the findings of the original study,…

Describes the development of educational computer software called scenario software that was designed to incorporate advances in cognitive, affective, and physiological research. Instructional methods are outlined; the need to change from didactic methods to discovery learning is explained; and scenario software design features are discussed. (24…

Presents study results examining behavior associated with preservation and destruction of slowly regenerating natural resources by using commons dilemma simulation games. Reports that neither environmental concern nor proenvironmental behaviors were related to commons dilemma performance. Concludes that cooperation and competition were better…

Modifications are proposed to the recently developed method of comparing one-step M-estimators of location corresponding to two independent groups that provides good control over the probability of Type I error even for unequal sample size, unequal variances, and different shaped distributions. Simulation results reveal cautions required. (SLD)

Describes shortcomings of computer science/engineering education and explains a new focus on informatics. Highlights include simulation, visualization, algorithmization, design of information processing models, parallel computing, a history of informatics, informatics versus physics and mathematics, and implications for education. (51 references)…

Four blind adults explored the spatial layout of landmarks in a large-scale space utilizing a microcomputer simulation of the environment and a tactile graphic aid of a similar environment. Although subjects learned the landmarks' locations faster using the tactile graphic aid, the accuracy of their spatial knowledge was equal with both…

Discussion of design principles in creating interactive video simulations for second-language learning focuses on two interactive video simulations on the Eurocentres Videodisc (ECVD). Four design principles are explained, instructional procedures involved in the ECVD are described, and learners' reactions are discussed. (four references) (LRW)
