A shopping exercise for the foreign language classroom is described. In this exercise, students contribute unused items, "money" is provided, and the students then set up stores and buy and sell the items. (RM)

Explains how to simulate dinner at a foreign restaurant to aid language learning in adult education classes. (CK)

The relatively new shadow test approach (STA) to computerized adaptive testing (CAT) proposed by Wim van der Linden is a potentially attractive alternative to the weighted deviation algorithm (WDA) implemented at ETS. However, it has not been evaluated under testing conditions representative of current ETS testing programs. Of interest was whether…

Possible bias due to sampling problems or low response rates has been a troubling "nuisance" variable in empirical research since seminal and classical studies were done on these problems at the beginning of this century. Recent research suggests that: (1) earlier views of the alleged bias problem were misleading; (2) under a variety of fairly…

A study was conducted to determine the effectiveness of "Discretion vs. Valor," a simulation game designed to give North American players a chance to: (1) identify with "believers" (Christians) in the Soviet Union in order to form new images of these persons; (2) gain empathy for Christians by understanding the dilemmas they…

The booklet offers general suggestions, a quiz, specific activities, and a checklist to increase children's awareness of the needs and characteristics of persons with disabilities. Preferred terminology is explained and ways to provide children with direct experiences with persons with disabilities are suggested. The brief quiz serves both to…

A method is proposed that increases the accuracies of estimation of the operating characteristics of discrete item responses, especially when the true operating characteristic is represented by a steep curve, and also at the lower and upper ends of the ability distribution where the estimation tends to be inaccurate because of the smaller number…

A course at California State University, Northridge, titled Applied Organizational Communication, allows students to apply their understanding of group and organizational communication theory to an actual situation and then in turn to analyze the observations in the organization in terms of those theories. The class forms a simulated organization…

This game simulates trade and food production in the West African region of the Sahel which is susceptible to drought. Players are divided into teams of two and four persons, each team assuming the role of a farming household in the Sahel. Teammates collaborate on production and trade decisions under conditions of dearth and plenty. The game…

Using simulated item response data, the performance of several "robust" and conventional schemes for ability estimation was evaluated in conjunction with logistic item response theory models (one, two, and three parameter models). The simulated item response data were generated using a model that is more complex than are the usual…

Simultaneous estimation of many parameters can often be improved, sometimes dramatically so, if it is reasonable to consider one or more subsets of parameters as exchangeable members of corresponding populations. While each observation may provide limited information about the parameters it is modeled directly in terms of, it also contributes…

This paper reviews the existing multidimensional item response theory (IRT) models and demonstrates how one of the models can be applied to estimation of abilities from a test measuring more than one dimension. The purposes of this paper were threefold. First, the fundamental concepts required when considering multidimensional models for the…

This paper describes an experiment in using the "scenario," a concept parallel to that of the case study, as a research tool for obtaining information about possible sex discrimination in personnel decisions by high school principals in South Australia. A review of the literature indicated that in spite of legislation aimed at…

The focus of this booklet is on the use of simulations in secondary school writing classes. After guiding the teacher through five key questions that need to be addressed in the planning and carrying through of each simulation, the booklet presents four simulations. Varying from simple to complex demands, the booklet's simulations include the…
