The construction of parallel tests from item response theory (IRT) based item banks is discussed. Tests are considered parallel whenever their information functions are identical. After the methods for constructing parallel tests are considered, the computational complexity of 0-1 linear programming and the heuristic procedure applied are…

Fisher's information measure for the item difficulty parameter in the Rasch model and its marginal and conditional formulations are investigated. It is shown that expected item information in the unconditional model equals information in the marginal model, provided the assumption of sampling examinees from an ability distribution is made. For the…

When latent class parameters are estimated, maximum likelihood and Pearson chi-square statistics can be derived for assessing the fit of the model to the data. This study used simulated data to compare these two statistics, and is based on mixtures of latent binomial distributions, using data generated from five dichotomous manifest variables.…

An overview of participative exercises of the game/simulation/case study type is provided, and seven distinct types of exercises are identified and briefly described; i.e., "pure" games; "pure" simulations; "pure" case studies; simulation games; games used as case studies; simulated case studies; and simulation games used as case studies. The…

The booklet describes the approach to career education for hearing impaired students developed by the Kendall Demonstration Elementary School (KDES) in the District of Columbia. The KDES model is described in terms of project direction and the seven model components: planning, staff development, program development, curriculum development,…

Two games are presented which demonstrate the complexity of the hazardous waste problem through an introduction to the: (1) economics of waste disposal; (2) legislation surrounding waste disposal; (3) necessity to handle wastes with care; (4) damages to the environmental and human health resulting from improper disposal; (5) correct ways to…

This siting game is based on the assumption that students will become involved in research required to determine the need for a power plant. Once the need is established, students must determine the location and type of plant to be built. There are brief character sketches which describe the key actors in the simulation. It is suggested that…

Legislation regarding penalty severity and control over punishment raises questions about the effect of potential penalties on verdicts. Experimental evidence from previous studies is mixed and subject to debate over the worth of simulations. In this study it was expected that the effect of penalties on verdicts would depend on strength of…

The paper describes a microcomputer simulation program developed to train preservice special education teachers in the use of basic behavior modification skills. The program was written in SuperPILOT on an Apple IIe using a BCD interface card and a Panasonic NV 8200 video tape recorder. Production suggestions are offered. The incorporation of…

The "Rainbow Shoppe", a two-hour distributive education preparatory project laboratory, is unique in its approach to simulating the real world of business because it uses computers to chart its sales, purchases, profits, and inventory. (Author)

This article describes a simulation by means of which college students better understand the process of bureaucratic growth and the effects of this structure on alienation from work and expressive relationships. A brief discussion on the general nature of gaming and simulation techniques is included. (Author/DE)

Describes eight activities using a swimming pool in which elementary school children can simulate collecting data from the oceans. (JR)

A dynamic environmental simulator that will enable people to experience a walk or a drive through scale models of urban, suburban, or natural environments is described. The potentials and limitations of the simulation are discussed. (JP)

The use of computer simulations as teaching devices in two psychology courses (statistics and research design and physiological psychology) is discussed. In the statistics and design course the primary purpose of simulation activities was to provide a problem and data set which could be used to practice skills acquired through a traditional…

This paper attempts to summarize briefly the history of the Denison University project for learning through simulation, detailing the range of research, development, education and training, and evaluational efforts which resulted in the establishment of the Denison Simulation Center. The paper includes an explanation of the services currently…
