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…

The future of educational research with the videodisc is discussed in relation to: (1) recent and planned hardware developments, and (2) research areas where videodisc technology may be appropriate. Examples of some of the different configurations possible among videodisc players, microcomputers, touch screens, and printers are provided. The…

Research efforts to model speech perception in terms of a processing system in which knowledge and processing are distributed over large numbers of highly interactive--but computationally primative--elements are described in this report. After discussing the properties of speech that demand a parallel interactive processing system, the report…

Instructional design considerations involved in using level four videodisc systems when designing simulations are explored. Discussion of the hardware and software system characteristics notes that computer based training offers the features of text, graphics, color, animation, and highlighting techniques, while a videodisc player offers all of…

This study investigated the effects on group performance of both the promotion origin of new leaders (from within the group or brought in from the outside) and the reassignment of the former leader (either remaining with or leaving the group). Using the National Aeronautics and Space Administration (NASA) moon survival exercise, same-sex groups of…

These instructional materials involve secondary students in simulating a criminal trial concerning teenage drinking. Included are all materials necessary for participation in the 1984 California Mock Trial Competition. Part I of the document describes a hypothetical situation involving a high school senior who faces state felony charges for…

Past research has shown that those in a subordinate (learner) role are more sensitive to how their leaders (teachers) feel about them than are leaders sensitive to their followers. This study was conducted to further investigate this phenomenon by assigning subjects to be either a boss or an employee. Subjects (N=120) interacted in pairs.…

Experiential learning has seen limited application in the preparation of higher education administrators. During recent years, however, simulation games which link cognitive social science knowledge with management skills have been applied to classroom training in this field. A National Center for Higher Education Management Systems (NCHEMS)…

Real test data of unknown structure were analyzed using both a unidimensional and a multidimensional latent trait model in an attempt to determine the underlying components of the test. The models used were the three-parameter logistic model and a multidimensional extension of the two-parameter logistic model. The basic design for the analysis of…

This research project analyzed the manifest and hidden curriculum of a sixth-grade writing project to determine how it transmitted societal values. Entitled "Right is Write", the writing project was a simulation game in which students played roles of writers, agents, editors, and publishers interacting to produce, evaluate, buy, and sell…

This paper explores new technologies, including computers and videodiscs, considering what they offer to education, how they can help contain educational costs, and how schools can begin to plan a smooth transition from today's primitive classroom environment to the electronically-equipped classroom of tomorrow. The introduction discusses general…
