This report summarizes the roundtable on information technology which brought together leaders from business, government, the non-profit sector, and academia to explore the use of complex adaptive systems as a model for determining information technology's role in both the workplace and diverse societal settings. Topics covered in this document…

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…

The use of paper and pencil, videotape recordings, and microcomputers in student testing provide three very different views of student achievement. Paper and pencil tests can record how students compose tests and documents, and how they critique documents or performances. Video recordings can record how students explain ideas, answer questions,…

This document reports an experiment designed to assess the effects of learner control over the level of challenge in computer-assisted instruction (CAI) and collect data that will guide the design of future learner control experiments. The subjects were 78 undergraduate students in the College of Education at a large public university. The CAI…

This simulation study involved the design of two two-stage tests in which the routing tests and the second-stage measurement testlets took the form of a multidimensional knapsack problem with prespecified target informations and constraints to be enumerated using the algorithm of E. Balas. Two conventional tests of similar length to the two-stage…

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 case is made for the use of computer assisted instruction (CAI) in Child Development Associate (CDA) training programs conducted on-campus in conjunction with an educational curriculum or conducted off-campus in conjunction with child care programs. The following points are made: (1) CAI can be used to supplement and amplify a teacher's…

This paper presents preliminary results of research founded on the hypothesis that in real environments there exist regularities that can be idealized as mathematical structures that are simple enough to be analyzed. The author considered three steps in analyzing the encoding of modularity of the environment. First, a general information…

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…
