In a computerized adaptive test (CAT), it would be desirable to obtain an acceptable precision of the proficiency level estimate using an optimal number of items. Decreasing the number of items is accompanied, however, by a certain degree of bias when the true proficiency level differs significantly from the a priori estimate. G. Raiche (2000) has…

Whether one should use null hypothesis testing, confidence intervals, and/or effect sizes is a source of continuing controversy in educational research. An alternative to testing for statistical significance, known as equivalence testing, is little used in educational research. Equivalence testing is useful in situations where the researcher…

The accuracy of Gibbs sampling, a Markov chain Monte Carlo procedure, was considered for estimation of item and ability parameters under the two-parameter logistic model. Memory test data were analyzed to illustrate the Gibbs sampling procedure. Simulated data sets were analyzed using Gibbs sampling and the marginal Bayesian method. The marginal…

This material provides students with information to prepare for a mock trial. The defendant in this case has been accused of the crime of driving under the influence of alcoholic beverages causing severe bodily injury. Case materials include stipulated facts, jury instructions, depositions, and other related materials. (EH)

This paper suggests that statistical significance testing and effect size are two sides of the same coin; they complement each other, but do not substitute for one another. Good research practice requires that both should be taken into consideration to make sound quantitative decisions. A Monte Carlo simulation experiment was conducted, and a…

Simulations were employed in a clerical skills training project for economically disadvantaged women in an attempt to relate the curriculum more directly to the student's needs. (AG)

Selection and training of coached clients and benefits resulting from their use (such as help in providing feedback to the trainee) are discussed. Reactions of students included in the program are given with suggestions for future improvements. (Author/EAK)

Discussed an instructional method for stimulating student interest in learning world history. (RK)

The instructional resource described, a game of learning activities, is designed to provide simulated experiences in how to find, apply, and interview for a job. (Author/AG)

A dynamic computer simulation of the four year college student has been conducted using the methods of system dynamics. (Author)

Some related mathematical models are presented of the bargaining process between an employer, or a group of employers, and a labor union. Its novelty is in the formulation and use of "reactive functions" to explain the attitudes of the respective parties at each stage of the negotiation process and its consequent time-path. (Author)

Discusses application of systems analysis to social and behavioral science as well as machine and non-machine systems. Presents rationale, principles, techniques, and advantages and disadvantages. (CJ)

The most recent simulation product of the University Council for Educational Administration (UCEA) is the Monroe City Simulation. The authors describe five generic issues that UCEA simulation developers must face in this kind of developmental work. (WM)
