Rasch between and total weighted and unweighted fit statistics were compared using varying test lengths and sample sizes. Two test lengths (20 and 50 items) and three sample sizes (150, 500, and 1,000 were crossed. Each of the six combinations were replicated 100 times. In addition, power comparisons were made. Results indicated that there were no…

A population data set was randomly generated from which a random sample was drawn. This sample was randomly divided into two data sets, one of which was used to generate parameter estimates, which were then used in the second data set for cross-validation purposes. The best variable subset models were compared between the two data sets on the…

Training of active duty forces is a never-ending process beset with challenges and lessons. Despite the widely shared view that today's military forces are the best trained forces in the world, some common recurring weaknesses reinforce the need for a continuing emphasis on repetitive training if U.S. forces are to be prepared to fight and win the…

A two-stage study was conducted to compare the ability estimates yielded by tailored testing procedures based on the one-parameter logistic (1PL) and three-parameter logistic (3PL) models. The first stage of the study employed real data, while the second stage employed simulated data. In the first stage, response data for 3,000 examinees were…

Research was undertaken to develop an experimental computer-based training system and to conduct a number of experiments in dynamic skill training using the system. (Training for such tasks is distinguished from the teaching of fact systems, the training domain most heavily studied in CAI applications.) Based on the hypothesis that the attentional…

Suitable for use in a high school social studies course, this class game simulates the political interaction and general unrest in the nine-month period following the death of Tsar Nicholas II in Russia in 1917. Eight class groups take the roles of the leaders of the following political factions: the bourgeoisie, nobility, Socialist…

Designed for high school world history courses, this classroom simulation recreates the power politics within the Roman Republic between 120 B.C. and the Battle of Actium in 31 B.C. Following an introduction which places the game in historical context, game preparation procedure is described. This includes assignment of Roman names, explanation of…

Teaching economics and consumer education is the topic of this annotated bibliography. The following kinds and amounts of materials are cited: (1) 10 citations from "Resources in Education" (RIE); (2) 10 citations from "Current Index to Journals in Education" (CIJE); (3) 35 commercially available "Student and Teacher…

A review of the theoretical and empirical literature was conducted to identify, in a systems framework, organizational processes and dimensions associated with effective functioning. Potential methodologies for use in controlled organizational experimentation were also explored. Literature was reviewed according to an empirically derived…

Computers in non-school settings, educational computer games, and education without schools are the primary topics covered in this three-section paper. The first section describes the use of personal computers in two different, non-school environments: the home and computer clubs. A "diary study" by Yaakov Kareev is summarized, in which…

Describes a four-phase method of helping students who are mathematically unsophisticated and have difficulty relating their common sense, English-language understanding of a system to an abstract, mathematical description. The approach uses interactive simulation models. (Author/IRT)

Artificial data were used to assess the correlation between several estimates of average student change in various schools and the true impact of those schools on the academic achievement of the student. (Author/DEP)

Introduction: The goal of information sharing is to change a person's image of the world and to develop a shared working understanding. It is an essential component of collaboration. This paper examines barriers to sharing information effectively in dynamic group work situations. Method: Three types of battlefield training simulations were…

The effect of dimensionality on an adaptive test's ability estimation was examined. Two-dimensional data sets, which differed from one another in the interdimensional ability association, the correlation among the difficulty parameters, and whether the item discriminations were or were not confounded with item difficulty, were generated for 1,600…
