The distinction between deterministic and statistical reasoning in the application of models to educational measurement is explicated. Issues addressed include the relationship between data and estimation equations, distinction between parameters and parameter estimates, and power of tests of fit of responses across the ability continuum.

Used simulation group approach in teaching social work students (N=6) technical and interpersonal skills. Results showed students found their interpersonal skills complementary to goals and dynamics of situations. Also observed students found learning of technical skills challenging in the context of a simulation group. (ABL)

It is demonstrated, theoretically and empirically, that item sets can be selected that meet the unidimensionality assumption of most item response theory models, even though they require more than one ability for a correct response. A method for identifying such item sets for test development purposes is presented. (SLD)

The authors describe how a small school district produced a major interactive video program on employability that won the Silver Star Award at the 1988 Houston Film Festival. Topics covered include obtaining financial support and assembling an ad hoc production company. (CH)

The effects of limiting the availability of immediate feedback while using LOGO were studied for 48 students aged 9 to 11 solving rotation problems. Limiting feedback reduced the incidence of trial and error strategies, and higher level problem solving strategies were apparently used to compensate for the restricted feedback access. (SLD)

A theorem is presented that describes conditions under which measurement invariance is consistent with predictive invariance for the linear case. These two forms of invariance are shown to be inconsistent under realistic conditions, and the duality is illustrated with simulated data. Implications for group differences research are discussed.

Summarizes recent advances in computer simulation and "reverse engineering" technologies, highlighting the Human Genome Project to scan the human genetic code; artificial retina chips to copy the human retina's neural organization; high-speed, high-resolution Magnetic Resonance Imaging scanners; and the virtual book. Discusses…

Instruction in computer-based business communication is vital to prepare students for the current environment. Course design should include hands-on training using electronic messaging, a simulated environment in which to practice networking, and encouragement of teams and collaboration among students. (SK)

Business students involved in group presentations (n=28), industry research projects (n=44), and computer simulation (n=51) rated each method on 10 criteria: interest, novelty, motivation, effort, business relevance, major relevance, course relevance, course improvement, learning, and difficulty. Simulation scored highest on 6 of the 10 areas. (SK)

This article presents a queuing model simulation of scientific productivity utilizing critical path analysis. Creativity is found to have a large positive effect, a negative effect, or no effect on productivity, depending on the stage of the problem-solving process to which it is applied and the nature of the bottlenecks inherent to the specific…

Examines the Triad Training Model for training counselors to better articulate a client's internal dialog during simulated counseling interviews. The theoretical basis for the model is discussed, positive and negative feedback is considered, and supporting research is presented. (Contains 20 references.) (LRW)

The analysis of contingency tables via set correlation allows the assessment of subhypotheses involving contrast functions of the categories of the nominal scales. The robustness of such methods with regard to Type I error and statistical power was studied via a Monte Carlo experiment. (TJH)

Computer simulation is an ideal framework to encourage decision making, active learning, and motivation. Appropriate software should be judged in terms of realism, relevance, complexity, interface, administrative efficiency, and use of microcomputers. (SK)

Describes step-by-step techniques that can be used to develop educational simulations for undergraduate biology students. Also discussed are simulations that are currently being developed with the support of the National Science Foundation. (ZWH)

A new approximation is proposed for testing the equality of "k" independent means in the face of heterogeneity of variance. Monte Carlo simulations show that the new procedure has nearly nominal Type I error rates and Type II error rates that are close to those produced by James's second-order approximation. (SLD)
