A simulation study was conducted to identify the best hot-deck variation to impute missing values. The three variations included in the study were the hot-deck random, the hot-deck sequential, and the hot-deck distance. The properties of these methods were investigated under three levels of the proportion of incomplete records and four levels…

In response to requests for information relating to the emotional maltreatment of children, the Region 6 Child Abuse and Neglect Resource Center produced a videotape depicting a fictional courtroom hearing conducted to determine whether or not a child should be temporarily removed from his parents' custody on the grounds of emotional maltreatment.…

The fourteenth in a series of profiles documenting experiences with the use of instructional technology describes the way an entire course can be shaped around a single game. Projects established to promote and support gaming and sources for more information on the subject are also presented. (Author/MLF)

The author lists the objectives of simulations and briefly mentions the types of games available and how they may be used in the classroom. (AG)

A discussion of the complex interrelationships that impinge upon the community college, and how systems development might assist in the decision-making process. (Author)

When circulation data are used as input parameters for a computer simulation of a library's circulation subsystem, the results of the simulation provide information on book availability and delays. The model may be used to simulate alternative loan policies. (Author/LS)

This study derived an expectation-maximization (EM) algorithm for estimating the parameters of multidimensional item response models. A genetic algorithm (GA) was developed to be used in the maximization step in each EM cycle. The focus of the EM-GA algorithm developed in this paper was on multidimensional items with "mixed structure."…

A discussion of using a simulation game as the entire focus for a course. (HB)

An exemplary project was funded in North Dakota to develop, implement, and evaluate a versatile office simulation program that would meet the needs of secondary students in varying situations. The Occupational Model Plan can substitute for, or complement the cooperative method in vocational office education. (Author/KP)

Various types of games are useful in the educational process both in school and beyond. This paper discusses some types and uses of games, as well as the issues involved, under these headings: nature of the learning process, educational games, nonsimulation games, gaming-simulations, simulations in urban planning, and gaming-simulations as…
